摘要:
A controller 103, based on the positional information of the display image, selects whether the 3-dimensional image data decoded by a decoder 102 is displayed stereoscopically (in 3-dimensional display mode) or planarly (in 2-dimensional display mode) and gives notice of the selected display mode to a display portion 104. Specifically, the input positional information=display address is monitored, and if no temporal change occurs, namely if the displayed position of the image data does not change, 3-dimensional display mode is selected as the display mode. On the other hand, if there is a temporal change, namely if the displayed position of the image data varies by scrolling, 2-dimensional display mode is selected as the display mode. Thus, an image data display apparatus which can efficiently display image data on a display when display of 3-dimensional image data is scrolled is provided.

A client (1) is provisioned with a content selection unit (13) for referencing description information (26), selecting content to be played in a certain period, and at the same time, and selecting content to be played at the next period from an id of a subset that is the same as the subset selected at the period, a request execution unit (14) for requesting the transmission of the selected content, and a content playback unit (15) for continuously playing the content transmitted in response to the request.

A prediction set determining section (13) selects a prediction set from a prediction set group including a plurality of prediction sets having different combinations of prediction modes corresponding to different prediction directions. Further, a prediction mode determining section (11) selects a prediction mode from the prediction set thus selected. An entropy encoding section (4) encodes the prediction set thus selected, the prediction mode thus selected, and residual data between an input image and a predicted image formed on the basis of the prediction set and the prediction mode. This allows an image encoding device to carry out predictions from more various angles, thereby improving prediction efficiency.
摘要:
A server (2) includes an index information generator (24) and an encoder (23). When a plurality of items of segment data (27) have been encoded up to predetermined sub segment data, the index information generator (24) generates index information (28) used for switching content, which serves as a playback subject, at this sub segment data. The encoder (23) causes a client (1) to obtain the index information (28) generated by the index information generator (24).

A search information analyzing unit (101) separates search information (15) into structured search information (152) representing a structure of moving image contents, semantic search information (153) representing characteristics in semantic context of the moving image contents, and signal search information (154) representing physical characteristics of signals of the moving image contents, and outputs the results. A structural search information disassembling unit (102) extracts and outputs, from the applied structural search information, information corresponding to at least one of the semantic search information and signal search information as structural information (50). A unit search information forming unit (103, 104) adds, to at least one of the applied semantic search information and signal search information, to form a small unit of search information (153A, 154A). Such a small unit of search information can be used as search information for the moving image contents, and hence, the amount of search information can be reduced.
摘要:
The present invention makes it possible to effectively encode/decode position information of leaves or nodes in tree-structured information by using a less amount of bits. The coding device according to the present invention includes a branching layer discriminating portion for identifying a hierarchical layer in which a leaf or node and a preceding leaf or node are separately branched and a position information coding portion for outputting a code corresponding to the identified hierarchical layer as a position information code for the leaf or node. Namely, merely information indicating a hierarchical layer in which a current leaf or node and a preceding leaf or node are separately branched is encoded as the position information of the leaf or node, thus increasing the efficiency of encoding leaf or node positions in the tree-structured information.
摘要:
Moving image decoding apparatus and moving image decoding method wherein the picture quality degradation is small even when an error occurs in decoding or the like in an coding system that refers to more than one frames to perform a prediction coding. An error correcting part (6) comprises an image selecting part (61) and an error concealing part (62). The image selecting part (61) selects a frame to be used as the image for the concealment and notifies the error concealing part (62) of, as information of the selected frame, the frame number (frame_num) of the selected image or the number of a frame memory in which the selected image is stored. The error concealing part (62) uses additional information and the selected frame information which is given from the image selecting part (61) to conceal the macro block where the error has occurred.
