[linux-sunxi] Re: tv-in documentation from allwinner?
the lack of parts (DVB tuners) that can feed a TS to the A20 so no proper integration with a DVB linux subsystem has been done. Oh, I missed the fact that the onboard part only does the TS part. If you need an external tuner, then indeed it's probably not worth the trouble. Stefan -- You received this message because you are subscribed to the Google Groups linux-sunxi group.

[linux-sunxi] Re: tv-in documentation from allwinner?
There is quite a bit of documentation on the MPEG-TS part. And some people have been looking into writing a driver, but lack of commonly available hardware to develop on slows things down. I suspect that lack of driver for that part is also a reason for the lack of boards that provide access to the DVB functionality :-( With good mali+cedar+ts drivers, the A20 would be a great platform to run Kodi, but sadly none of those three has seen much activity.

I suspect that lack of driver for that part is also a reason for the lack of boards that provide access to the DVB functionality :-( yeah, but i suspect the problem is the other way around.. the lack of parts (DVB tuners) that can feed a TS to the A20 so no proper integration with a DVB linux subsystem has been done. as far as i can see there are some choices: * ready to go but expensive: NIMs from Sr-systems http://sr-systems.de/content.php?show=Produktelng=engstyle=std they showcase the proper busses TS+I2C for being driven by a sunxi card (but they are professional gears: 100€ or so for such a card).. * Extension card for the Octopus Digital Devices DVB bridge: i really suppose this too is based on link with TS+I2C between base DVB bridge card to PCI express and extension (DVB tuners/ CI modules..) BUT some investigation still needed: http://www.digitaldevices.de/english/Octopus_PCIe_Bridge.html * _slightly_ less expensive but with high hacking value :-) , the Hauppauge Triplestick, pretty powerful USB DVB dongle composed of two boards, one is the DVB tuner and the other is the USB driver, here a good naked review: http://blog.palosaari.fi/2014/04/naked-hardware-15-pctv-triplestick-292e.html if you desolder the _tiny_connector (1mm step IIRC), you can again have the TS+I2C (+VCC/GND) stuff. the SiLabs tuner/demod is pretty unknown as there are no PDF freely available, but powerful, and it's already supported by Linux, so you could use the dongle as it is, through USB, and save the effort to link it to the DVB Allwinner subsystem.. that was the best i could put together, but maybe other can share other solutions. of course i've no economic interest in any of these vendors. and sorry if we have hijacked the analog tv decoder main topic! -- You received this message because you are subscribed to the Google Groups linux-sunxi group.

This is AW at its best! Selling H/W and not providing the proper documentation or even source code showing how the H/W block works! It is no coincidence that many people simply gave up on all this totally lost company called All Winner.
