In a digital receiver which can easily store broadcast information, a one-period amount of data is separated from a data broadcast signal. The one-period amount of data has an amount of data corresponding to plural frames which are periodically repetitively transmitted in the data broadcast signal. The one-period amount of data is stored in a data storage device, thereby simplifying the construction of the data storage device.

A repeat use data inserting apparatus for repeatedly inserting repeat use data into program data in accordance with appropriate timings. The apparatus comprises a data holding unit and a data multiplexing unit. The data holding unit holds the repeat use data made of a plurality of material data in the form of separately encoded streams. The data multiplexing unit multiplexes separately encoded streams of a plurality of material data constituting the program data during a period other than a data insertion period during which the repeat use data is inserted into the program data. The data multiplexing unit further inserts repeatedly the repeat use data into the program data during the data insertion period by multiplexing the separately encoded streams of the plurality of material data constituting the repeat use data held in the data holding unit.

The moving image encoding device for encoding a plurality of moving image signals of this invention includes: a plurality of encoding sections for encoding the plurality of moving image signals, the encoding sections being provided with a plurality of quantization sub-sections for quantizing the plurality of moving image signals with predetermined quantization widths; and a quantization control section for controlling the quantization widths used by the quantization sections simultaneously.

A content distribution system including a server device for selecting and distributing video scenes according to a user request, and a terminal device for receiving the video scenes from the server device. The server device stores a plurality of content files. Each content file includes a plurality of pieces of scene data together with scene additional information regarding playback of each piece of scene data. The server device selects pieces of scene data matching the user request, reads scene additional information from each content file containing the selected pieces of scene data, generates, based on the read scene additional information, selected-scene additional information, and transmits the selected pieces of scene data in association with the generated selected-scene additional information. The terminal device receives and stores the selected pieces of scene data and the selected-scene additional information.

In order to reduce the amount of data to be transmitted by a transmission apparatus, the transmission apparatus transmits control sub-information to a receiving apparatus separately from video data which is actually distributed, and eliminates redundant distribution of video data. The receiving apparatus stores the received video data and creates content in accordance with the control sub-information.
