摘要： It is possible to correctly decode data which has been encoded by a variable length encoding method in which the compression ratio is increased. The variable length encoding method encodes a predetermined unit of data by referencing a parameter table and includes: an initialization step for setting an acquired parameter table to a initial value; a parameter table information encoding step for encoding information on the parameter table which has been initialized; a parameter acquisition step for acquiring from the parameter table an encoding parameter used for encoding each sub-data constituting the predetermined unit of data; a sub-data encoding step for variable-length-encoding the sub-data by referencing the acquired encoding parameter; and an information encoding data arrangement step for arranging the encoded information at a position where the information can be acquired prior to the encoded predetermined unit of data and outputting it.

摘要： There are provided a medium data display device, a medium data display method, and a medium data display program for displaying multi-medium data consisting of a plurality of media including a moving picture on a display screen by various display methods. The medium data display device (85) is a device for displaying multi-medium data consisting of a plurality of media including a moving picture on a display screen and includes a scaling judgment section (87), a scaling section (89), and a display section (19). The scaling judgment section (87) judges whether to modify the image size of the moving picture when displaying it or display it without modifying the image size. The scaling section (89) and the display section (19) are means for displaying the multi-medium data and perform display by switching whether to perform scaling according to the judgment result of the scaling judgment section (87).

摘要： A data transmission device (100) causes a data reception device to execute appropriate reproduction of content data. The device includes: a file analysis section (110) and an RTSP processing section (101) for establishing and initializing a content data transmission path to the data reception device and after this, acquiring reproduction control information from an MP4 file and transmitting it to the data reception device; an RTP creation section (102) for acquiring content data from the MP4 file via the file analysis section (110) and packetizing it; and an RTP transmission section (103) for transmitting the content data packetized by the RTP creation section (102).
