EPG Sr.

2011-01-01T11:46:53Z

Woddfellow2: Undo revision 951 by Loldongs (Talk)

Ran on the Amiga 1000 and 2000 platforms. The software came in two varieties: A full-screen version that looked a lot like the [[EPG Jr.]], and a split-screen version that looked like the first version of [[Prevue List|Prevue Guide]]. Text and image advertisements could be shown in the top half of the screen in this version. Unfortunately, we do not currently have either version of the EPG Sr. software.

Prevue Channel

Woddfellow2: Undo revision 952 by Loldongs (Talk)

The '''Prevue Channel''' (known from 1988-1993 as '''Prevue Guide''' and from 1999-2007 as '''[[TV Guide Channel]]''') was a network founded by [[United Video Satellite Group]] in 1988. Prevue has utilized several different types of hardware over the years, including [[:Category:Prevue_Software|Atari and Amiga-based machines]].

==TV Guide Transition==

In 1999, [[UVSG]] acquired TV Guide from News Corp, and on February 1st, 1999, the Prevue Channel was relaunched as the [[TV Guide Channel]] at exactly 12:00 AM. YouTube user HulkieG has posted a video of the switch [http://www.youtube.com/watch?v=rLApAmSQQ5U on YouTube]. Several months after this name change, the existing [[Prevue Grid]] Amiga-based platform was phased out, replaced by a Windows NT-based system referred to as [[Yellow Grid]] due to its new appearance.

Many fans of the Prevue Channel regard this relaunch as the beginning of TV Guide Channel's downhill climb. In 2001 and 2002, the channel's programming began to drastically change, andome were turned off by the half-hour advertisements and constant "celeb-talk". The channel began moving away from the previews and highlights that had been the foundation of Prevue Guide.

==Logo History==
The original Prevue logo trademark had a USPTO serial of 74108440.

[[File:PrevueOriginal.gif]]

An alternative version of the logo, without the guide text. This was used as the primary logo just after the "Prevue Guide" name was phased out, and is filed with the USPTO under serial 74491852.

[[File:PrevueText.png]]

This version of the logo, introduced around 1996, continues to use Prevue's typeface, but introduces an eye-like design around it. This logo has a USPTO serial of 75066864.

[[File:PrevueEye.png]]

The final version of the Prevue logo used the same eye-like style with the '''Univers''' font instead of the original Prevue typeface. This logo has a USPTO serial of 75463258, and the trademark was not cancelled until 2006.

UVSG Satellite Data

2011-01-01T11:46:31Z

Woddfellow2: Undo revision 953 by Loldongs (Talk)

This was the format used by [[United Video Satellite Group]] to send data out at 2400 baud over a satellite feed. Many different types of information were sent out through this feed, including time/date information, system settings, channel listings, and system updates.

Tin has successfully reverse engineered parts of this format, and it is now possible to send our own messages to emulated or real EPG/Prevue machines over serial. Additionally, some test files received from an ex-UV employee have helped to further the reverse engineering effort.

==Overview==

Every box on message always starts with the header "55 AA", followed by a [[select code]], a 00, and a checksum. A command is started with a "55 AA", then a byte indicating which mode of command is being sent out, then the data of the command, which is usually followed by checksum.

For example, here are two commands that will tell an EPG machine to listen, then change its title to "PREVUE GUIDE":
55 AA 41 2A 00 94 55 AA 54 50 52 45 56 55 45 20 47 55 49 44 45 00 D0

In this example, the select code being addressed is 2A, or the ASCII code for an asterisk (*). This means every machine that is connected to the satellite feed will act on this command. Then, a 00 to terminate the string, and a checksum (94). After the 55 AA, you see the mode byte (54, or T for '''T'''itle), and then an ASCII string (PREVUE GUIDE). Lastly, there is another 00 to terminate the string, and D0, the checksum for the entire string.

==Initial Checksum==

Most commands have a checksum that is calculated on all the bytes of the data part of the command. This is sent over the serial port and compared to the correct value by the receiving machine. If the checksum does not match, the computer discards the whole command. The checksum is calculated by bitwise XOR of each byte of data within the command excluding the command letter itself. Each command has its own hardcoded seed checksum which is loaded as the initial value of the checksum as soon as the initial command letter is recieved.

==Command Modes==

Some of this is conjecture and named according to clues found in the reverse-engineered code - it's subject to change and mistakes! Some of the checksums were found from an Atari disassembly, and a few were found by running UVSG sample messages through [[UVSGXOR]].

Select code

2011-01-01T11:46:10Z

Woddfellow2: Undo revision 955 by Loldongs (Talk)

The '''select code''', also known as a serial number, is a unique alphanumeric string that identifies each EPG/Prevue piece of hardware. When [[UVSG Satellite Data|commands]] are sent out to the guide machines, they are addressed by select code. Some commands use asterisks as wildcard characters in the serial numbers so that, for example, the time or a system update can be sent out to all machines at once.

[[File:Ad_-_Prevue_Grid.png|200px|thumb|right|Prevue Grid displaying an ad]]
'''Prevue Grid''', also known as '''blue grid''' and '''a2-blue''', was the final iteration of the Prevue software, used from 1993-1999. Like [[Prevue List]] and [[EPG Sr.]], Prevue Grid ran on the Amiga platform. There were many differences between these three Amiga-based software editions, however. Whereas [[Prevue List]] displayed a list of what was currently on on each channel, then what would be on in the future at different times, the Prevue Grid showed what was on each channel currently and in the future at the same time.

The Prevue Grid software had 3 different names over the course of its history: Prevue Guide, Prevue Channel, and lastly, for just a few months, TV Guide Channel. Only one version of the Prevue Grid software, which is thought to be the final version, is currently known to be on the internet. This is version 9.0.4, with TV Guide Channel branding. This copy of the disk contains listings from December 13th 1999. If one were to set their Amiga (emulated or real) to that date, said listings would suddenly appear and start scrolling. As the software internally counts days from January 1, the year is unimportant, but if a leap year is used, make sure to select December 12th instead. Under emulation, the most reliable way to set the Amiga date is to change it on the host computer, as WinUAE will always reset the clock to that of the host upon a reboot.

YouTube clips: [http://www.youtube.com/watch?v=rLApAmSQQ5U Blue Grid Example] [http://www.youtube.com/watch?v=NSwIHoFaAfQ Emulated Blue Grid Example]

[[File:System_Initializing_-_Prevue_Grid.png|200px|thumb|right|The Blue Grid software initializing displaying the software version and select code]]
[[File:Screen_shot_2010-11-28_at_12.03.50_AM.png|200px|thumb|right|The Blue Grid's Scroll Speed can go over 9000 (9001 displayed here, a few minutes before was brought down from 9003)]]

==Specifications==

This version of the Prevue Grid software requires the following minimum specifications:

*2.04 or 2.05 Kickstart ROM
*Chip RAM: 1.0MB
*Fast RAM: 1.0MB
*CPU: 68000
*Chipset: ECS

When running it under emulation, it's a good idea to make the window size 760x480 - this causes the image to be perfectly centered in the window. To create screenshots with the proper aspect (to simulate what you'd get from a video capture on a real Amiga), crop the 760x480 screenshots down to 740x480, then resize it using a bilinear algorithm to 640x480.

[[File:Guru_Error.jpg|200px|thumb|right|Common Amiga Guru Meditation error produced by Prevue Grid]]
This particular Guru Meditation error is caused by insufficient chip RAM. Insufficient fast RAM will not cause a Guru Meditation, but it will cause the software to throw an ER011 error and freeze up. It is '''not''' compatible with Kickstart 3.1 - the software will boot, but there are major graphical problems. It is compatible with the AGA chipset, but requires softkicking with a 2.x ROM in order to avoid the glitches.

==Operation==

The software has several different modes, which are accessible through the system's menu. To access the menu, press ESC while in listings mode. The keyboard commands that are available depend on which mode the software is in. While in Diagnostic mode, any keypress that is not recognized by the software as a valid command will dump back out to the main menu.

===Listings mode===
'''Ctrl-B''' - this shows '''SCRLSPD = ''x'' ''' to appear on the top half, showing the current scroll speed.

'''Ctrl-C''' - this causes the software to redraw the screen. This is not done cleanly - there are glitches while it happens, but it redraws the screen freshly.

'''Ctrl-D''' - this causes the scroll speed to decrease by one (making it faster). This also allows access to the "disallowed" speeds 0 and 1.

'''Ctrl-E''' - this causes the scroll speed to increase by one (making it slower). If you press '''Ctrl-B''' beforehand, the on-screen speed will change as well.

'''Ctrl-G''' - this causes the software to draw a calibration grid, useful for adjusting an attached monitor to ensure that none of the image is being cut off at the edges. If done in Listings mode, it can cause display corruption which will be repaired once the listings have a chance to cycle around. This works in Diagnostic mode too, but causes the software to erroneously begin using the listings font to draw the diagnostic menu, instead of the ad-editing font, causing text to be positioned incorrectly.

'''Ctrl-S''' - this causes the listings to switch into single-step mode. Each keypress of Ctrl-S from this point will make the listings scroll one step, then stop.

'''Ctrl-U''' - once the current "block" fully scrolls on the screen, the clock will stop and no more blocks will scroll onto the screen, parking the floppy drive and enabling a safe reboot or shutdown.

'''C''' - this causes the current color palette to be displayed on top of the listings.

'''F''' - this causes text to appear on the top half denoting some internal settings. It is currently unknown how to modify these settings.

'''G''' - this triggers graphical ad mode, which currently goes through all the banners present on the disk.

'''H''' - shows CLU (~channel) information on the top half of the screen (use ad mode (shift-A) first to see it clearly). Each press steps through the list. CTRL-H steps backwards through the list.

'''J''' - shows PI (programme information) on the top half of the screen, according to which ever CLU was just selected by pressing H. Each press steps through the list. CTRL-J steps backwards through the list.

'''K''' - tries to load clock.cmd from DF0: which fails given the disk we have (although there is a ClockCmd=1 shown on the diagnostics when pressing F)

'''L''' - switches off overscan - possibly a function when using a monitor to view the output of the Amiga.

'''N''' - this causes the top half to switch to color 0, enabling display of external video via the genlock.

'''P''' - reload gradient.ini from DF0: (use unknown)

'''S''' - this causes the listings scroll to continue.

'''Y''' - cycles the colour indexes of the 32 colour palette used on the top half. The graphics ("logos") on the disk we currently have are all in 320x240 32 colours. Adverts are actually shown on a 32 colour screen, although only 8 colors are accesible via the editor. Press it 32 times to return to the "normal" palette.

'''/''' - this cycles through 9 "Viewmode" tests on the top half. They cycle through different resolutions and different positions (left half, right half, full screen).

'''Shift-A''' - this causes text ads to appear on the top half, and will cycle through all ads that are marked "active" through the menu.

'''Shift-D''' - this causes the software to reload its current listings from its cache stored on disk.

'''Shift-K''' - creates (in the background) a list of the logo files within DF0:logos and (seemingly) updates DF0:logo.lst

'''Shift-N''' - this causes some diagnostic text stating "BitPlane1 = 40468" to appear over the listings. Numbers seen have been 40468, 3C3A8 and 38568. Unsure as to the reason this exists.

'''Shift-S''' - this causes the listings scroll to stop.

'''Shift-T''' - this seems to have the same effect as Shift-A at the moment. It is unknown what difference there is to Shift-A.

===Diagnostic mode===
'''Shift-1''' - Changes TEXT between L, S, N, and R. L most likely means Local, as setting TEXT to L is the only way to access the Edit Ads and Edit Attributes main menu items. Unsure about the others but it's possible that either S (serial) or R (RS-232) refers to feeding ads in over serial. S may also refer to Satellite (though operationally this would be the same as Serial).

'''Shift-2''' - Changes VIN between L, I, Z, N, Y, and y. Perhaps VIN refers to Video INput? Conjecture at this point without a manual or some good old RE'ing.

'''Shift-3''' - Changes LINE between 6, 5, 4, and 3. This controls the maximum number of text lines per ad.

'''Shift-4''' - Changes GRPH between L, R, S, N, and Y. Once again, it is unknown what this means, perhaps it allows the PowerPacked IFF files to come in from another source, allowing graphic updates without exposing the UI to the viewer?

'''Shift-9''' - Causes a brief pop-up above the visual indicators for these settings that says Start TAPE Video.

'''Shift-0''' - Causes a brief pop-up in the same spot as Shift-9 that says stop.

'''1''' - Causes '''KHHR''' to change to '''Silence''', but this does not persist when you re-enter the diagnostic screen.

'''2''' - Causes '''Left''' to appear in this spot.

'''3''' - Causes '''Right''' to appear in this spot. Looks like it might be used to test the audio source that goes to air?

'''4''' - Causes '''Background''' to appear in this spot.

'''5''' - Causes '''Ext. Video Only''' to appear haphazardly over the "Press any key to continue." prompt.

'''6''' - Causes '''Computer Only''' to appear there.

'''7''' - Causes '''Overlay Ext. Video''' to appear there.

'''8''' - Causes '''Negative Video''' to appear there.

'''9''' - Causes '''Video Switch Open''' to appear where the earlier Start and Stop message did.

'''Ctrl-A''' - Shows all free RAM types.

'''Ctrl-C''' - Shows free chip RAM.

'''Ctrl-F''' - Shows free fast RAM.

'''Ctrl-M''' - Shows largest contiguous block of RAM.

'''C''' - Shows julian date information again overlaid over other information. Julian day and next represents CURDAY and NXTDAY. jday1 and jday2 are the julian dates found in the cached files.

==Special Characters==

The following is a list of special characters available on the Prevue Grid software in the listings. These characters are drawn from the [http://ariweinstein.com/prevue/PrevueC.font.png PrevueC.font] file, but the order of the characters does not quite match up exactly with their order in the font itself. These were discovered by editing the curday.dat file, which contains the current listings cache.

* 80 - Right Triangle
* 81 - Upside-Down Right Triangle
* 82 - Right Double Triangle
* 83 - Upside-Down Double Right Triangle

==Known Error Codes==
[[File:ER009.png|200px|thumb|right|ER009 is shown because TVGBANNR.UV is missing]]
* ER005 - Attempt to boot on 1.x Kickstart (cannot actually be seen, since 2.0 is the minimum KS for the Amiga FFS format)
* ER007 - No listings data available
* ER009 - The wrong color palette is being used in the file defined in Banner.ini, the color palette must contain 8 colors
* ER010 - The resolution of the file defined in banner.ini is too large

[[File:Ad_-_Prevue_Grid.png|200px|thumb|right|Prevue Grid displaying an ad]]
'''Prevue Grid''', also known as '''blue grid''' and '''a2-blue''', was the final iteration of the Prevue software, used from 1993-1999. Like [[Prevue List]] and [[EPG Sr.]], Prevue Grid ran on the Amiga platform. There were many differences between these three Amiga-based software editions, however. Whereas [[Prevue List]] displayed a list of what was currently on on each channel, then what would be on in the future at different times, the Prevue Grid showed what was on each channel currently and in the future at the same time.

The Prevue Grid software had 3 different names over the course of its history: Prevue Guide, Prevue Channel, and lastly, for just a few months, TV Guide Channel. Only one version of the Prevue Grid software, which is thought to be the final version, is currently known to be on the internet. This is version 9.0.4, with TV Guide Channel branding. This copy of the disk contains listings from April 1, 1999. If one were to set their Amiga (emulated or real) to that date, said listings would suddenly appear and start scrolling. As the software internally counts days from January 1, the year is unimportant, but if a leap year is used, make sure to select March 31 instead. Under emulation, the most reliable way to set the Amiga date is to change it on the host computer, as WinUAE will always reset the clock to that of the host upon a reboot.

[[File:System_Initializing_-_Prevue_Grid.png|200px|thumb|right|The Blue Grid software initializing (with a custom serial number)]]

==Specifications==

This version of the Prevue Grid software requires the following minimum specifications:

*2.04 or 2.05 Kickstart ROM
*Chip RAM: 1.0MB
*Fast RAM: 1.0MB
*CPU: 68000
*Chipset: ECS

When running it under emulation, it's a good idea to make the window size 760x480 - this causes the image to be perfectly centered in the window. To create screenshots with the proper aspect (to simulate what you'd get from a video capture on a real Amiga), crop the 760x480 screenshots down to 740x480, then resize it using a bilinear algorithm to 640x480.

[[File:Guru_Error.jpg|200px|thumb|right|Common Amiga Guru Meditation error produced by Prevue Grid]]
This particular Guru Meditation error is caused by insufficient chip RAM. Insufficient fast RAM will not cause a Guru Meditation, but it will cause the software to throw an ER011 error and freeze up. It is '''not''' compatible with Kickstart 3.1 - the software will boot, but there are major graphical problems. It is compatible with the AGA chipset, but requires softkicking with a 2.x ROM in order to avoid the glitches.

==Operation==

The software has several different modes, which are accessible through the system's menu. To access the menu, press ESC while in listings mode. The keyboard commands that are available depend on which mode the software is in. While in Diagnostic mode, any keypress that is not recognized by the software as a valid command will dump back out to the main menu.

===Listings mode===
'''Ctrl-B''' - this shows '''SCRLSPD = ''x'' ''' to appear on the top half, showing the current scroll speed.

'''Ctrl-C''' - this causes the software to redraw the screen. This is not done cleanly - there are glitches while it happens, but it redraws the screen freshly.

'''Ctrl-D''' - this causes the scroll speed to decrease by one (making it faster). This also allows access to the "disallowed" speeds 0 and 1.

'''Ctrl-E''' - this causes the scroll speed to increase by one (making it slower). If you press '''Ctrl-B''' beforehand, the on-screen speed will change as well.

'''Ctrl-G''' - this causes the software to draw a calibration grid, useful for adjusting an attached monitor to ensure that none of the image is being cut off at the edges. If done in Listings mode, it can cause display corruption which will be repaired once the listings have a chance to cycle around. This works in Diagnostic mode too, but causes the software to erroneously begin using the listings font to draw the diagnostic menu, instead of the ad-editing font, causing text to be positioned incorrectly.

'''Ctrl-S''' - this causes the listings to switch into single-step mode. Each keypress of Ctrl-S from this point will make the listings scroll one step, then stop.

'''Ctrl-U''' - this will sometimes cause the software to disregard future keyboard input. The actual function of this command is unknown, but once the current "block" fully scrolls on the screen, the clock will stop and no more blocks will scroll onto the screen. Don't do this unless you wish to reboot, unless you can determine what it actually does.

'''C''' - this causes the current color palette to be displayed on top of the listings.

'''F''' - this causes text to appear on the top half denoting some internal settings. It is currently unknown how to modify these settings.

'''G''' - this triggers graphical ad mode, which currently goes through all the banners present on the disk.

'''N''' - this causes the top half to switch to color 0, enabling display of external video.

'''S''' - this causes the listings scroll to continue.

'''Y''' - this causes the software to cycle through 32 colors on the top half, even though the hires screenmode normally in use only allows 16 colors. Press it 32 times to return to the "normal" palette.

'''/''' - this cycles through 9 "Viewmode" tests on the top half. They cycle through different resolutions and different positions (left half, right half, full screen).

'''Shift-A''' - this causes text ads to appear on the top half, and will cycle through all ads that are marked "active" through the menu.

'''Shift-D''' - this causes the software to reload its current listings from its cache stored on disk.

'''Shift-K''' - causes the software to alternately read from track 62, then track 6. Unknown what data it is reading.

'''Shift-N''' - this causes some diagnostic text stating "BitPlane1 = 40468" to appear over the listings. Unsure as to the reason this exists.

'''Shift-S''' - this causes the listings scroll to stop.

'''Shift-T''' - this seems to have the same effect as Shift-A at the moment. It is unknown what difference there is to Shift-A.

===Diagnostic mode===
'''Shift-1''' - Changes TEXT between L, S, N, and R. L most likely means Local, as setting TEXT to L is the only way to access the Edit Ads and Edit Attributes main menu items. Unsure about the others but it's possible that either S (serial) or R (RS-232) refers to feeding ads in over serial. S may also refer to Satellite (though operationally this would be the same as Serial).

'''Shift-2''' - Changes VIN between L, I, Z, N, Y, and y. Perhaps VIN refers to Video INput? Conjecture at this point without a manual or some good old RE'ing.

'''Shift-3''' - Changes LINE between 6, 5, 4, and 3. This controls the maximum number of text lines per ad.

'''Shift-4''' - Changes GRPH between L, R, S, N, and Y. Once again, it is unknown what this means, perhaps it allows the PowerPacked IFF files to come in from another source, allowing graphic updates without exposing the UI to the viewer?

'''Shift-9''' - Causes a brief pop-up above the visual indicators for these settings that says Start TAPE Video. This would undoubtedly be used to test the functionality allowing locals video ads to run on the top half, because of the next item...

'''Shift-0''' - Causes a brief pop-up in the same spot as Shift-9 that says Stop.

'''1''' - Causes '''KHHR''' to change to '''Silence''', but this does not persist when you re-enter the diagnostic screen.

'''2''' - Causes '''Left''' to appear in this spot.

'''3''' - Causes '''Right''' to appear in this spot. Looks like it might be used to test the audio source that goes to air?

'''4''' - Causes '''Background''' to appear in this spot.

'''5''' - Causes '''Ext. Video Only''' to appear haphazardly over the "Press any key to continue." prompt.

'''6''' - Causes '''Computer Only''' to appear there.

'''7''' - Causes '''Overlay Ext. Video''' to appear there.

'''8''' - Causes '''Negative Video''' to appear there.

'''9''' - Causes '''Video Switch Open''' to appear where the earlier Start and Stop message did.

'''Ctrl-A''' - Shows all free RAM types.

'''Ctrl-C''' - Shows free chip RAM.

'''Ctrl-F''' - Shows free fast RAM.

'''Ctrl-M''' - Shows largest contiguous block of RAM.
