Abstract:
A multichannel broadcasting system for outputting a plurality of broadcast contents to a plurality of output channels comprising:a storage unit for supplying said plurality of broadcast contents; a plurality of main output buffer apparatuses corresponding to said plurality of output channels, respectively, for storing said plurality of broadcast contents and for transmitting the stored broadcast contents to the corresponding output channels in accordance with a predetermined transmission order; means for assigning a priority order to said broadcast contents to be transmitted to said plurality of output channels on the basis of said predetermined transmission order; a backup output buffer apparatus for storing said broadcast contents from said storage unit based on said priority order prior to the transmission of said broadcast contents from said main output buffer apparatuses to said corresponding output channels; and a control unit for controlling said backup output buffer apparatus so that said backup output buffer apparatus transmits said broadcast contents stored therein to an output channel of a failed main output buffer apparatus instead of said broadcast contents stored in said failed main output buffer apparatus when said failed main output buffer apparatus fails, wherein in the event of a failure occurring in any of said plurality of main output buffer apparatuses, said control unit assigns said backup output buffer apparatus as a main output buffer apparatus to said output channel corresponding to said failed main output buffer apparatus; and thereafter, signals of broadcast contents to be transmitted to said corresponding output channel corresponding to said failed main output buffer apparatus are copied from said storage unit to said backup output buffer apparatus, and when said failed main output buffer apparatus is fixed, said control unit catalogs said fixed failed main output buffer apparatus as said backup output buffer apparatus; and broadcast contents to be transmitted to said plurality of output channels are copied from said storage unit to said fixed failed main output buffer apparatus cataloged as said backup output buffer apparatus based on said priority order.
