Abstract:
Data apparatus operable with a host computer, said apparatus comprising:a schedule data bus; a scheduler separate from said host computer for receiving request information from said host computer and in response thereto for generating scheduled data for instructing reading and multiplexing of data clips stored in a data store; a reader for sequentially reading from said data store the stored clips in the form of transport stream packets corresponding to said scheduled data, said transport stream packets being allocated to a plurality of channels; a multiplexer for time-divisionally multiplexing the transport stream packets output from said reader in accordance with said scheduled data, and without being separated into respective ones of said channels of transport stream packets; and a data transmitter for transmitting the time-division multiplexed transport stream packets output from said multiplexer, whereby said host computer is not directly coupled to said schedule data bus and whereby said scheduler, said reader, and said multiplexer are directly coupled to said schedule data bus so as to enable said scheduler to supply said scheduled data to said reader and said multiplexer.
