Hi Shine, In general, Uri does not work for Siano anymore, so Linux related issues can be directed to Udi (CC). For the issue you raise below: Operating SMS1180 CMMB requires a user mode host stack, on top of the driver. CMMB has a proprietary data format, proprietary control table etc. It is not based on MPEG2 transport steam live DVB-T or ISDB-T.

I was about to write drive for it under Linux, but I found some SMS messages I can't recognise: SMS messages with header 0x026a, 0x026b, 0x026f, 0x028d, 0x028e, 0x0300 and 0x0301. These messages should be for CMMB. I want to know the messages format and what these header ID mean but I can't find these definations in current siano source code. Could you give me some help on this?
