ABSTRACT:
A cell-discard control apparatus includes an encoding unit for encoding voice/image information in accordance with a prescribed coding scheme. An information dividing unit divides the encoded data into basic information data and detail information data. A basic information cell assembling unit assembles the basic information data into basic information cells. A detail information cell assembling unit assembles the detail information data into detail information cells. A basic information multiplexing unit multiplexes basic information of a plurality of channels for transmission. A detail information multiplexing unit multiplexes detail information of the plurality of channels for transmission. A cell output unit outputs the basic information multiplexed cell and the detail information multiplexed cell and preferentially discards the detail information multiplexed cell in the event of congestion.
