Abstract
A particular implementation correlates a broadcast media item, which has a metadata element containing either a station call sign or channel number for a program, to a specific broadcast frequency and a virtual channel that a service provider broadcasts the program on. A command string is algorithmically defined to encode the frequency and physical channel, and is presented to the tuner hardware for locking onto and decoding the signal. A URL including the command string can then be generated. Consequently, a DLNA client device can engage a media renderer to play the broadcast media item through the exchange of a URL and a control interface.
