DTMB support for DVB API


It has been rather slow progress week. Initially I started studying changes needed to support SDR (Software Defined Radio) via Kernel API. For me it sounds quite easy and logical to extend DVB API for SDR. Just adding new delivery system and implement other relative small changes for DVB-core. After some discussion on Linux-Media mailing list, idea of extending DVB API was refused as V4L2 API is more correct API for that kind of stuff. V4L2 API covers FM-radio, camera, web-camera and analogue television stuff whilst DVB API is used only for digital television. Unfortunately I have quite zero experience from V4L2 devices. After hacking with Silicon Laboratories Si472x based USB FM-radio I decided to leave whole SDR for a while. Have to get more suitable radio for V4L2 learning...

DTMB support for DVB API

After adversity with the SDR I decided to do easier DVB enhancements I planned. DTMB (Digital Terrestrial Multimedia Broadcast) is Chinese digital television standard and there is some existing Linux Kernel drivers for that standard. One of those drivers, HDIC HD29L2, was made by me in last autumn and initial interest is coming from there. Big work for whole DTMB API support was done during last Christmas holiday. I even ran some initial RFCs but never finalized work. Learning many research papers and listing all the used parameters, finding out equivalent ones from the existing API, was quite many working days in that time!

1. [PATCH RFCv3] add DTMB support for DVB API
2. [PATCH RFCv3] add DTMB support for DVB API


  1. Sorry to resurface that 2012 blog post about DTMB but I will need to do some scans in HK/China and was wondering if you could have some advice of an USB device that should work under Linux? Looking for HDIC HD29L2 chip-set I'm in pain to find a model reference? One device referenced as working under Linux is
    MyGica D689 but some forum seems reporting some tuning issues...
    Many thanks.

    1. No idea. I did HD29L2 linux driver, but I suspect device I used is never released.
