A method and apparatus for interface adapting IPTV with a stream media device, including: an adaptation layer receives the batch commands from the service layer and judges the type of the batch commands; the adaptation layer judges the type of the batch commands, and analyzes or generates the batch commands into the atom commands respectively; the adaptation layer stores the analyzed or generated atom commands in the queue according to the constraint condition of the atom commands in the stream media device; the adaptation layer obtains the atom commands from the queue and transmits the request to the stream media device when the constraint condition is satisfied; the adaptation layer judges the performing result, if successful, ends process; otherwise, the adaptation layer selects the corresponding transmission mode according to the predefined policy. Using the invention, supplier can use a variety of stream media devices expediently and provides services for stream media consumers more conveniently and effectively.
