I don't think this ATI chipset is supported by linuxTV and have had no joy search google as others also hit a dead end. Hello, I'm working on writing a partial userspace driver for this device from traffic dumps presently. I believe that it supports / performs similar functions to the rtl-sdr project, but with better specifications (minus the great tuner range of the E4000). See https://github.com/roysjosh/tvw-sdr for current progress. I suspect it can send 8MHz at 12 bits resolution (it sends roughly 125Mbps through the USB interface when listening to an FM station). Currently, my code initializes the T507 and uploads the firmware blob(s) and all register readouts match. Also, my code does it in under 2 seconds (including a 1 second sleep after the 2nd blob upload) compared to the over 45 seconds the closed driver needs. I can reach the TDA18271 through an I2C bridge, but I don't configure it yet. I'm considering how to use existing code rather than write my own from scratch, as much code already exists (as was mentioned already). I would love some help, especially from people who are able to safely RE without legal issues.

ATI theatre 750 HD tuner USB stick
Hi all, My name is Fisher Grubb, I have an ATI (now AMD) theatre 750 HD based TV tuner USB stick. I don't think this ATI chipset is supported by linuxTV and have had no joy search google as others also hit a dead end. I have put USB bus dump for that device and the chip part numbers at the bottom. Please may I have a quick reply if someone looks at this, thanks. Model number is U5071, manufacturer site: http://www.geniatech.com/pa/u5071.asp I think this is a very impressive piece of hardware as it can do: Analogue TV, DVB, AV capture and S video capture. There is an IR receiver on board and came with IR remote control. I'm happy to provide any info on it that you may want such as picture of board chips. I'm almost finished my electronics degree and so can do hardware probing if someone may give me something specific to look for. I'm also happy to run software or commands to dump stuff or even help with dumping things from the windows drivers if I've given directions etc. Thank you, Fisher lsusb: Bus 002 Device 021: ID 0438:ac14 Advanced Micro Devices, Inc. sudo lsusb -vd 0438:ac14 Bus 002 Device 021: ID 0438:ac14 Advanced Micro Devices, Inc.

Re: ATI theatre 750 HD tuner USB stick
Hi all, I was in contact with AMD today regarding this tuner haveing no support on Linux and I was given a link for a feedback form and told to get specific needs from www.linuxtv.org to help the cause and if there were enough people, then the AMD developers may help. Of course I wouldn't be surprised if people will have to reverse engineer it from the windows drivers but I thought I would mention it. I could not find any info on this 750 HD on www.linuxtv.org regarding where it stands. What help is needed for it?

I'm not sure why they would direct you to linuxtv.org. *They* are the ones with all the information that the linuxtv community would need. Of course I wouldn't be surprised if people will have to reverse engineer it from the windows drivers but I thought I would mention it. I could not find any info on this 750 HD on www.linuxtv.org regarding where it stands. What help is needed for it? 1. Datasheets for the 750 (under NDA is fine), but they need to agree to allow them to be used to author a GPL driver. 2. Reference driver sources which can be legally incorporated into a GPL driver. 3. Firmware with a license that permits free redistribution. I attempted to work with them back in 2009 on the T316 chip (an ATSC/ClearQAM demodulator), and they couldn't provide all of the above. Perhaps things have changed since then but I doubt it (in particular, the sale of their TV chip unit to Broadcom left all sorts of unknowns regarding who owns the relevant intellectual property). Finally, even if you get the above, there still needs to be some developer who has the time/interest to do the work. While three years ago the big challenge was getting access to the datasheets, nowadays a much bigger problem is there are no developers who are both qualified and not already too busy with other work. Bootstrapping a new chip like that is probably a 50-100 hour investment for somebody who is experienced in this area, which is a fairly big chunk of time if the developer doesn't have any vested interest.

We sold our multimedia DTV division to Broadcom several years ago. IANAL, so I don't know exactly what rights we retained for the IP. You may need to talk to Broadcom now.

Chips: ATI: T507 0930 MADE IN TAIWAN P0U493.00 215-0692014 T507 driver is the missing piece. I suspect that SoC integrates many chips, USB-bridge (with IR etc.), DVB-T demodulator and analog decoder. Getting it work as DVB-T device is not mission impossible even without a specs. Reverse-engineering is fun ;-) Generally speaking DVB-bridge is very simple, no problems at all to reverse. DVB demodulator is little bit harder but still possible without loosing even sensitivity. What you lose is configuration options like how IF frequency, SNR, BER is calculated. Tuners are most tricky as there is all kind of calibration routines etc. but in that case tuner driver exists. NXP: TDA18271HDC2 P3KN4 02 PG09361 That TDA18271 driver already exists - even two different drivers. regards Antti -- http://palosaari.fi/ -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
