摘要： A communication terminal, includes: a communicator, configured to transmit and receive data to and from a server storing video contents; an accumulator, configured to accumulate a plurality of partial streams extracted from different time positions within the video contents received through the communicator as asynchronous streams; a decoder, configured to decode at least one of the asynchronous streams and synchronous streams that are not extracted as the asynchronous streams from the video contents, the synchronous streams being streaming-distributed from the server; and a controller, configured to acquire streams having time position information before and after a reproduction time position of the at least one of the asynchronous streams and the synchronous streams decoded by the decoder while the at least one of the asynchronous streams and the synchronous streams are reproduced on the display, and control the display to display the acquired streams after the reproduction.

摘要： In distribution of high definition video signals in which it is possible to freely move viewing regions, systems and methods allow for determining viewing movement without dependence on user operation. In at least one embodiment, a video region of an input video signal is divided into a specified number of regions, and generates a plurality of video signals corresponding to each of the divided regions. The plurality of video signals are encoded to generate a plurality of video bit streams that are stored in a video bit stream group storage section. A video bit stream is extracted from the storage section based on the viewpoint movement information, and a transmission video bit stream is transmitted to a receiving unit. Viewpoint movement information is determined in order to specify a region for viewing from among the video regions. The viewpoint information is determined regardless of user instruction, based on specified data.

摘要： The delivery of the high-definition image signal corresponding to an area a user desires to view can be achieved without increasing the load of processing in a transmitting apparatus. There are included an image area dividing unit (20) for dividing the image area of an input image signal into a given number of areas to generate area division image signals; and a coding unit (30) for coding the area division image signals to generate image bit streams. There are also included an image bit stream group accumulating unit (40) for accumulating a plurality of image bit streams; and a view point information receiving unit (60) for receiving view point information including the information of a view position transmitted from a receiving apparatus (2). Then, it has been arranged that an image bit stream corresponding to a first area defined by a view position and an image bit stream corresponding to a second area that is a peripheral area of the first area be extracted from the image bit stream group accumulating unit (40), thereby generating transport image bit streams to be transmitted to the receiving apparatus (2).
