Abstract
In reproducing the AV contents, the information concerning the configuration of reproduction block (e.g., GOP) composing the AV contents is needed. In the case of network reproduction, it was requisite that an AV contents reproducing apparatus acquired this information from an AV server. The present invention provides an AV contents reproducing method, an AV server and an AV contents reproducing apparatus in which this information is unnecessary to transmit or receive. The AV contents reproducing apparatus transmits a reproduction start request by specifying the start request position, and the AV server starts to transmit the AV contents from the top position of reproduction block (e.g., GOP) near the start request position.
Claims21
An AV server comprising:
- store means of holding one or more AV contents containing video, image and/or audio and composed of a plurality of reproduction blocks;
- reproduction request receiving means of receiving an AV content identifier that is the information for identifying the AV content and a reproduction request having the start request position information that is the information indicating the start request position designating from which position to start the reproduction for the AV content identified by said AV content identifier;
- transmit data determining means of determining the top of reproduction block as the transmission start position when said start request position indicated by said start request position information is coincident with the top of reproduction block, and determining the top of reproduction block before or after said start request position indicated by said start request position information as the transmission start position when said start request position indicated by said start request position information is not coincident with the top of reproduction block;
- and
- transmitting means of transmitting the AV content identified by said AV content identifier provided in said reproduction request received by said reproduction request receiving means from said transmission start position.
