LIDIC USB interface

I'm pretty sure that the LIDIC interface provides a two-way digital stream of data between the BW and the LIDIC, so you can change channels, and receive Video/Audio back.

I wondered if the same interface might provide for a DAB+ radio, that is, change channels, and receive Video/Audio back.

I'd really like my BW to become my media centre with music as much as video.

A twin HDTV tuner plus DAB+ tuner would sure be sweet. Someday......

My point was that the existing hardware/firmware has 99% of this ready to go "today". No new tuner needed.

Are you saying that HDTV tuners can pick up DAB+?

No, I'm saying that the LIDIC produces a digital feed that the BW can store/playback. All that is required is a device that receives DAB+, that translates its output into the same format as the LIDIC, which the BW can then deal with.

I hope it gets the aspect ratio correct

The aspect ratio of radio -- I'd like to see that

All the music will be in 3/4 or 9/16 time.

Apologies to Dave Brubeck but probably in 5/4 time

If you have a DAB receiver that has Stereo RCA outputs then you can use the LiDiC (or A/V input on the DP-P2) to record and/or timeshift DAB radio broadcasts.

You could connect the LiDiC to a Windows PC's USB2 port and record it onto the PC's HDD. But you could just as easily use the PC's stereo input(s) to record into any of the BW's supported audio formats.

Ick! But at least it's possible.

And apparently allowed in the Copyright Act under the same conditions that allows timeshifting a TV broadcast:

COPYRIGHT ACT 1968 - SECT 111
Recording broadcasts for replaying at more convenient time

(1) This section applies if a person makes a cinematograph film or sound recording of a broadcast solely for private and domestic use by watching or listening to the material broadcast at a time more convenient than the time when the broadcast is made.

My emphasis.

Has anyone who actually has a LiDiC plugged the device into their computer to see what vendor and product id it returns?

Why do I care?

A LiDiC streams Audio and Video to a BW. There is no reason that the stream has to come from a device connected to a LiDiC, it could perhaps come from another device altogether like a PC pretending to be a LiDiC, which is sending Internet Radio, or YouTube, or DAB+ radio to the USB port of the BW.

It's not a direct answer to your question, but Beyonwiz has released the source code for WizDR, a Windows program that allows a PC to capture data from the LiDiC. It should reveal a bit about how the LiDiC communicates over the USB connection. The source code is on the Beyonwiz corporate downloads page, under Source Code.

Oooh, goodie

Nice idea!
This is kind of what prompted me to have a fiddle with the WizPNP protocol to build a WizPNP server (rather than client like Peter built). So that is how "wizmongoose" was born (a web server called "mongoose" that I hacked around with the source in order to put in the WizPNP protocol communications and mimick a beyonwiz WizPNP server). So with a bit of thought, this could be expanded to sooo much more. The motiviation behind this was to make files in a directory shareable to the Wiz via the WizPNP protocol rather than Windows sharing as soooo many people struggle to setup Microsoft Windows network file sharing properly.

The reason I chose mongoose: one exe/binary file, no libraries, C rather than C++, only 2 C files to worry about, rather than directory structures full of them (hard to track what is going on with multiple source files, much easier to go through a simple structure of only 2 files). So the binary is tiny, I compiled one to run on Windows, on the NSLU2 slug, on win32 linux, and Mac users can also compile it. I made all the changes in programmers notepad, I don't have a C dev environment (learning a dev environment is probably longer than the couple of weeks I spent on the whole thing!).
