Default DIY DTS/DD processor?

I could swear I've seen this come up on the forums, although maybe it was on another one. Has anyone tried to DIY a processor for DTS/Dolby Digital? I was talking about this the other day with my brother. There seems to be a few all-in-one chips from Cirrus and TI that may do the trick, but I'm wondering ahead of time if this will be a futile attempt. If there is a thread that exists on this subject, please give me a link. Thanks.

Plenty of threads about this I should think.

Basically, you need a license from Dolby/DTS to purchase the chips and MOQ is typically 1000 pcs. In short: Many have tried, none have suceeded....


PS: IIRC some people have build something themselves, but always starting out with the DSP-board from a scrapped DVD or receiver.

Try the STA310 from ST Microelectronics.

The Dolby AC-3 spec (as A/52) is published and available almost anywhere on the net, and there's lots of software already that can decode it. For DTS, look around for libdca / libdts... originally it was part of VideoLAN, but it's been pulled from development due to patent issues.

Both will give you a decoder that you can port to a DSP, if you're so inclined. Just you won't be able to share the DTS version.

Would it be possible to use the chips out of a (old/cheap/dead) DVD 5.1 player??
The DIY bug. Nothing is ever finished.

Possibly, if it's not a one-chip solution, which connects directly to the transport and outputs I2S, unless you can find the RAW data stream on the transport cable and send something else.
