hi,Mauro: thanks for replying. i am not sure the dtv api can be used in my project.because cmmb's protocol is different to dmb :(
in Windows, we download firmware using windows driver,config fx2 as bulk transfer,and read the TS stream,finally decode it and display. I also read this post: "http://www.linuxjournal.com/article/7466"---- Writing a Real Driver―In User Space. if i just want to read the ts stream,should i use this method? or another way?

If the driver will support just digital TV, you don't need V4L2 API, just DVB API. The latest version of the API's are at: http://linuxtv.org/downloads/v4l-dvb-apis/ In order to start, you need first to understand the API. Then, you'll need to get one driver as an example (for example, cxusb.c - if the device is USB). If the driver also supports analog TV, then the better is to use a driver that supports both API's, like em28xx Cheers, Mauro -------------------------------------------------------- ZTE Information Security Notice: The information contained in this mail is solely property of the sender's organization.
