APPARATUS AND METHOD FOR CODING VIDEO, AUDIO AND ADDITIONAL DATA ACCORDING TO CONDITIONAL ACCESS OF TERRESTRIAL DMB AND CONDITIONAL ACCESS SYSTEM USING THE SAME |
摘要 |
Provided is an apparatus for coding a video, an audio and additional data according to a conditional access of terrestrial DMB. The apparatus includes an analyzing unit for analyzing input stream; a scrambling control unit for selecting a stream to be scrambled according to a selection signal; a transport stream de-multiplexing unit for de-multiplexing the input stream received from the analyzing unit, parsing an audio, a video and additional data classified by a packet identifier (PID), and outputting a stream to be scrambled, a stream not to be scrambled and the packet identifier (PID) for the stream to be scrambled according to selection of the scrambling control unit; a control word generating unit for generating a control word; a scrambling unit for scrambling the stream to be scrambled which is outputted from the transport stream de-multiplexing unit based on the control word generated in the control word generating unit; a conditional access data generating unit for receiving the control word from the control word generating unit and generating conditional access data; and a transport stream re-multiplexing unit for receiving and re-multiplexing the stream to be scrambled from the scrambling unit, the stream not to be scrambled from the transport stream de-multiplexing unit. |
