"It can do PAL-BGHID, PAL-M, PAL-N, NTSC, NTSC_J. It just a matter of programming the TV-out hardware. We might not support all standards from the beginning though."
The RPi does have a bunch of I/O on a header. I believe they can be configured for a variety of applications, I think the 8 bit GPIO is the one. I2C could be handy too.. The expansion connector descrioption is:-
Top row, left to right:
Bottom row, left to right:
- all the UART, SPI and I2C pins can be reconfigured as GPIO if needed.
- some of the do-not-connect (DNC) pins will likely be replaced by
GPIO in a subsequent board revision.
Pity the NZ version of DigiLite software is being developed on an x86 platform. The code might not port to the RPi as it is arm based. Anyway at under 30 quid and consuming very little power this little ''toy' looks as if it could be useful. The screenshots I have seen of the composite output are not bad at all and it does have the USB ports too (Digilite transmit version 1.999b???) as well as the above header. We shall find out when they get round to clearing the order list and I have one to play with.
I must be patient. I must be patient. I must be patient. I must be patient...............................
DigiLite Transmit is written in C, so it should port over quite easily with changes to the input and output routines. I wonder if it will run V4L2? Could you attach a PVR USB2 to make a compact solution?
I see they've started shipping at last.
I have found a linux driver for the WinTV PVR USB2 but have yet to try it. It is in c with a makefile so will need compiling on the target machine. I will look into that later.
The limiting factor will be how fast the Raspberry Pi can transfer data. It will be abysmally slow writing to the SD card. 6MB/S on sequential write but around 2MB/S random read. Probably better with a USB hard drive. The RPi only has two USB ports but are channelled through one port at core level. Handling the WinTV and transmit paths simultaneously may be asking too much so I expect it will only be possible to play pre-recorded .mpg files via a linux version of DigiLite Transmit.
Don't hold your breath!
I have a beagleboard i got last year (before the Pi was revealed.. bad timing eh! ) for the same thing, they aparrently handle the pvr usb fine, unfortunately not had time to try much with it yet.
They have released some information (under duress)

But not on the video part of their chip as far as I can see. Shame as it has a nice MPEG4 encoder/decoder as part of it.
You would be better off using a cheap Chinese FPGA board and a video DAC from AD.
