HD Radio

With more and more stations supporting HD Radio, it would be nice to see support for HD Radio in the SoundBridge .

HellerMD98,

that indeed would be a nice feature. Hopefully the Roku people will find a way to put the necessary digital FM tuner into one of the next firmware updates.

There is zero chance I'm afraid. HD radio requires much more processing power than the DSP in the SoundBridge products can provide. (I have in my recent career worked for a company selling HD radio solutions.)

Objection, Your Honour! The DSP will easily handle all HD signals that the Soundbridges can receive.

Hi KlaasV,

It's not the codec that is the problem - as I understand it, it is the recovery of the digital stream from the AM or FM signals that is the problem. A 400MHz Blackfin is not sufficient for that. The first HD decoders used an array of Sharc DSPs. Later ones (TI chips) use single C64xx class DSPs. More than that I cannot say without breaching non-disclosure agreements.
