Digital broadcasting apparatus for the transmission of additional information with a digital broadcast with adjustment of the bitrates of additional information data items |
摘要 |
<p>A digital broadcasting apparatus includes: a bitrate storage unit for holding a bitrate set for each source data item and a total bitrate available for transmitting source data items; a transmission period storage unit for holding transmission time period of each source data item; a source data reading unit for reading each source data item to be transmitted from a source data storage unit; a rate control unit for calculating a transmission bitrate of each source data item that should be simultaneously transmitted according to predetermined equations; and a data multiplexing unit for multiplexing each source data item read by the source data reading unit into a transport stream at the transmission bitrate calculated by the rate control unit. <IMAGE></p> |
