Abstract: To receive new services including audio or video content for presentation by a cable-compatible digital television or other digital audio/video receiver, a module may be connected to the HOST-POD interface of the digital television. The module has a receiver for receiving audio or video content in a first compression format, a transcoder for converting said audio or video content from the first compression format into a second, different compression format, and a controller for transmitting the audio or visual content in the second compression format to the digital television over a HOST-POD interface. By using such a module, front-end components of the digital television may be bypassed while back-end components may be utilized to decompress and present the content. The module may be a PC card or smart card for example.
