Patent ID: 7849492

Claim:
A receive accumulating apparatus configured to receive i) at least one of video and speech data and ii) file-format data which are sent as they are multiplexed with each other from the side of a sending apparatus, which multiplexes i) at least one of video and speech data encoded based on a stream transmission protocol and ii) file-format data encoded based on a file transmission protocol with each other and sends i) at least one of said video and speech data and ii) said file-format data as a single stream, and temporarily accumulating, in a predetermined accumulation area, i) at least one of said video and speech data and ii) said file-format data as they directly are in the form of a single stream, wherein all or some of said file-format data are decoded later at predetermined timing and accumulated in another accumulation area, which is different from said predetermined accumulation area, once again as a file, i) at least one of said video and speech data and ii) said file-format data which are temporarily accumulated in said predetermined accumulation area as a single stream are reproduced by utilizing all or some of said file-format data which are accumulated in said another accumulation area once again, a PID filter capable of performing separation of i) at least one of said video and speech data and ii) said file-format data is utilized, a PID corresponding to at least one of said video and speech data and a PID corresponding to said file-format data are set up in order for said PID filter not to perform said separation so that i) at least one of said video and speech data and ii) said file-format data are both passed through the PID filter without being filtered to be temporarily accumulated directly in the form of a single stream, in said predetermined accumulation area, and said PID corresponding to said file-format data is set up in order for said PID filter to perform said separation so that said all or some of said file-format data are decoded later at said predetermined timing, when a load upon the receive accumulating apparatus becomes smaller than a predetermined value after i) at least one of said video and speech data and ii) said file-format data have been accumulated in said predetermined accumulation area, and accumulated in said another accumulation area once again as a file.
