Abstract:
A format converting apparatus for converting data of a first format structure into a second format structure, comprising:a first selector which selects m number from M number of received isochronous channels, where m&gE;1, and multiplexes the selected m number of isochronous channels; a second selector which selects n number from N number of received asynchronous channels, where n&gE;1, and outputs the selected n number of asynchronous channels; a format converter which analyzes control commands contained in the selected n number of asynchronous channels to extract OSD information, converts and packetizes the extracted OSD information into a transport packet structure; and a multiplexer which multiplexes the outputs from the first selector and the format converter, and outputs a multiplexed stream with a data rate matching a bandwidth of the second format structure.
