    摘要： There is provided a content recording device capable of performing content reproduction with a plurality of qualities while limiting the use of the content. The device includes a content acquisition unit for acquiring a basic layer indispensable for content reproduction which is obtained by hierarchically encoding at least one of the parameters of the resolution, bit rate. and frame rate and an extended layer for interpolating it; and an access control unit for recording the basic layer, the extended layer, and use control information, moving the basic layer recorded in a basic layer recording unit and the use control information recorded in a use control information recording unit to an external content recording device. and deleting the moved basic layer from the basic layer recording unit, thereby enabling reproduction of the content with various qualities by a plurality of devices as well as reproduction with the original quality while satisfying the use limit posed on the content.

    摘要： A video transmitting apparatus that is able to efficiently transmit and decode only the video data of the region of interest without lowering coding efficiency, and that is able to change the region of interest during reproduction of video. In this apparatus, a base layer coding section (116) codes the base layer of low resolution obtained by reducing input video of high resolution. A region map calculating section (118) calculates a region map indicating the divided region upon coding, and an enhancement layer coding section (120) performs intra-frame coding for each divided region after dividing the enhancement layer which is differential video of the input video and video obtained by decoding the base layer coded video and expanding the same to the resolution of the input video according to the region map. Here, an offset table generating section (122) generates an offset table indicating the storing position of the coded enhancement layer for each divided region, and a video data clipping section (136) clips the video data corresponding to the region of interest only from the enhancement layer using the offset table.
