摘要： If a loss of a RTP packet is detected, a RTT acquisition unit acquires time information corresponding to a period of time needed from transmission of data from a transmitting apparatus to reception of this data at a receiving apparatus. A QoS switching unit determines based on the time information whether moving image data is to be retransmitted that was transmitted from the transmitting apparatus but that has been lost without being received by the receiving apparatus or moving image data located in playback time sequence after the lost moving image data is to be encoded without referring to the lost moving image data and the resultant encoded moving image data is to be transmitted.

摘要： A change amount detector calculates the amount of change between frames in a predetermined display range in an image corresponding to image data. When the calculated amount of change is larger than a first threshold, a redundancy determining portion determines the number of data of redundant data such that the number of data of the redundant data for image data in the predetermined display range is increased. A communication controller transmits data containing image data based on the determined number of data of the redundant data.

摘要： Information that identifies key frames in video data within multimedia data is generated as reproduction controlling data and the reproduction controlling data is positioned at a predetermined position in the multimedia data. Upon special reproduction, the reproduction controlling data can be used to easily identify, read out, and reproduce key frames that should be used for random access and the like. By positioning the reproduction controlling data in an area within the multimedia data that is ignored by conventional apparatuses, file compatibility can be also maintained. This attains increased efficiency of special reproduction processing of multimedia that has ISO Base file format or a similar format.

摘要： A magnetic recording/reproducing apparatus is disclosed wherein reproduced signals read out from a plurality of recording tracks using a reproducing head can be separated into original recording signals of the recording tracks. Upon recording, an identification signal which has a recording wavelength equal to or greater than a minimum recording wavelength and causes no interference of any of the recording tracks with any adjacent one of the recording tracks is appended to and recorded together with a recording signal in order to allow, upon reproduction, acquisition of the position information of the reproducing head with respect to the plural recording tracks of the magnetic recording medium. Upon reproduction, a reproduced signal for each of the recording tracks of the magnetic recording medium is generated on the basis of the positional information read from the recording tracks.
