How to feed a DSS signal to your PC................................ Subject: Re: How can I feed DSS digital stream to a PC??

As it happens, I've recently been working on this. Getting the decrypted MPEG data out of the receiver is easy. In the 2nd and 3rd generation Sony receivers, both the audio and video are transferred across an 8-bit data bus from the transport stream demuliplexer ASIC to the SGS/Thomson STi3520 decoder. There are two associated strobe signals, one each for video and audio. The data is set up about 100 nS before the leading edge of the strobe, and the strobe is active low for about 40 nS. The first generation receivers are similar, but use separate audio and video decoders (SGS/Thomson STi3500 and TI TMS320AV110). Getting the data into a PC is tricky because the burst data rate is about 2.5 Mbytes/second, which is a bit much for a non-bus-mastering ISA card. For my prototype I'm using a PLX/Twin 9050RDK PCI prototyping card to which I've added a FIFO chip, some buffers, miscellanous control logic, and a connector. Using the satellite reciever to play back the captured data seems difficult at best, because the STi3520 doesn't seem to be smart enough to play back an MPEG stream without processor intervention. My current plan for playback is to try to play the video through a C-cube ZiVA-DS decoder chip on a Creative Labs Dxr2 decoder (part of the Creative Labs PC-DVD Encore Dxr2 package).

I don't think there is much value to examing the data at that point, since it is still encrypted. Unless, of course, you're trying to reverse-engineer the conditional access system :-) Cheers, Eric
