PVR

Here are some modifications I've made to the Digitel+ HT8400 PVR firmware (April 2012/1.02.3A). Unfortunately, I wasn't able to crack of the one checks it makes, so before I go to the trouble of creating instructions for how to load it into the unit (you'll need a null-modem cable), I'll see if there's any interest first.

• blink the clock colon a bit more consistently
• use INPUT to toggle between channel and clock
• use the left-most line to indicate recording; as a consequence, switch to 12-hour time for hours 20 to 23 (so during recording the hour goes 19, 8, 9, 10, 11, 0)
• update the clock during standby recording

• enter three digits to jump to a specific minute (e.g. 120 will jump to exactly 2 hours)
• start with Red or Green to jump backwards or forwards that many minutes (e.g. Green 10 will jump forward 10 minutes)
• pressing Slow after Pause will set ¼ speed
• allow jumping and MARK during pause/forward/rewind/slow (unfortunately, the picture is not updated during pause)
• Down & Up will skip four times Left & Right (i.e. one minute with the default jump of 15 seconds)

• don't show the number if it's 1
• add a space between the title and number
• remove the space between month and year
• use a lighter shade of green for viewed titles
• sorting by name will sub-sort by time (oldest first)
• Move will preserve the time
• added a "Clone" option to Copy/Move (like Copy but a lot quicker and it updates the time to reflect the current playback position; intended as a pseudo-split)

• start with the existing name (truncated to 28 characters)
• always start the number at 1, increasing until it doesn't exist
• update list order when done

• use apostrophe (') instead of caret (^)
• swap Delete & Clear with case & save (Delete's image just uses the right arrow, Clear is like a space; case becomes "Table" and save is "Done")
• set initial position to the new clear
• allow the text cursor to wrap
• INPUT & SLEEP can be used as OK

• start in this mode
• slight improvement to next/prev day
• page up will move up an entire page
• blank out the time when "No synopsis available"
• stop chopping off the descenders (j is not i!)
• use INPUT to reset the EPG (for all channels)

• if the next program starts in less than 16 minutes and that is also less than half the total length, use the next program's title & info
• Down & Up will change time by 30 minutes

• fix length across midnight

• ignore case when testing extensions
• recognise flv (although whether it plays depends on the encoding), mpg and xvid

• enable telnet (and tweak the prompt)
• reboot after crash
• run a program (HT8400.run) from the front USB after powerup/reboot
• press INPUT immediately (within quarter-second) followed by SLEEP to exit (and reboot)

• prevent MON_EIT being registered twice
• set the date via Micom to avoid fsck seeing future times
• bypass "ssdcheck" (couldn't crack it, but trivial to ignore)

• remove the space in the "Children's" category
• remove the leading 0 from day and hour for most times and use space instead of slash to separate day and month
