A video processing apparatus includes a conversion unit and a transmission unit, and an external device includes a reception unit and a restoration unit. The conversion unit converts one or a plurality of elementary streams complying with ISO/IEC 14496-1:1999 into one data stream. The data stream includes a plurality of multiplexed packets, each multiplexed packet including both a Synchronization Layer (SL) packet and an elementary stream identifier of the SL packet. The transmission unit transmits the data stream to the external device using an isochronous or bulk transfer. The reception unit receives, from the external device, the data stream that is transmitted using the isochronous or bulk transfer. The restoration unit restores the data stream to one or a plurality of elementary streams complying with ISO/IEC 14496-1:1999.

Video processing apparatus and method of controlling video processing apparatus

A communication apparatus for receiving video data transmitted by streaming from a transmission apparatus via a transmission path includes a video data reception unit configured to receive the video data, a reception data monitoring unit configured to monitor a processing status of the video data received by the video data reception unit, and a control request transmission unit configured to transmit a playback control request for the video data to the transmission apparatus, wherein, when the video data is played back at a playback speed, if the reception data monitoring unit determines that the playback speed exceeds a transmission capacity of the transmission path or a processing capacity of the communication apparatus, the control request transmission unit transmits to the transmission apparatus a playback control request to request only intra-picture coded video data.

Communication apparatus and communication method

This invention provides a data processing apparatus, data processing server, and data processing system, which can easily edit data by utilizing features of object-based coding, and can easily generate object-based encoded multimedia data. A multimedia edit & playback terminal () issues an edit instruction of multimedia data to a multimedia edit server () that edits multimedia data consisting of a plurality of object data. A communication client () receives layout information of multimedia data. A playback unit () displays the acquired layout information, and an edit designation unit () designates desired one of the displayed layout information. The designated layout information is output via the communication client ().
