You need the I2C programming manual of your DVB tuner to be able to do the channel tuning. Usually this manual can get from the manufacturer of the RFIC tuner chip set.

General I2C specification can find here:

Dear vfone,
thanks for your response.
I need STB6100 datasheet and STB0903B datasheet, but I can not find the full datasheet on the net. Can you help me?
