Abstract: A content distribution system comprises a script generation unit. The script generation unit determines a distribution request time, which is the time when the terminal issues a request to a server for the distribution of the items of content, and a reproduction start time, which is the time when the terminal starts reproduction of the content included in the content list, at which it is anticipated, on the basis of a content list which is a list of content to be reproduced at a terminal and on the basis of the distribution state of the content, that the content included in the content list can be reproduced at the terminal without interruption. The script generation unit then generates a script which describes the distribution request time and the reproduction start time that have been determined, and transmits the generated script to the terminal.

Abstract: After an input image signal (2000) of a smaller resolution is encoded by an encoder (20), an input image signal (1000) of a greater resolution is subjected to motion compensation processing by a motion compensation unit (102) according to motion information (1998), thereby generating a prediction error signal (1001). Simultaneously with this, an enlarged decoded image (2003) obtained by enlarging the decoded image (2002) obtained by an encoder (20) is subjected to motion compensation processing by a motion compensation unit (103) according to the motion information (1998), thereby generating a prediction error signal (2005). By referencing the prediction error signal (2005), the prediction error signal (1001) is subjected to conversion encoding, quantization, and entropy encoding.

Abstract: In a time/space-division filtering, a moving image signal in a certain resolution-hierarchy, for which time hierarchizing is performed, is divided into a time low-band signal and a time high-band signal. A moving image signal, which has the moving image signal corresponding to the time high-band signal reconstructed by employing the time low-band signal and the time high-band signal, is generated. A reduced image signal having the moving image signal reduction-processed is generated. A high-band generating process by space hierarchizing is performed for the time high-band signal, thereby to generate a time high-band/space high-band signal. The time low-band signal, the reduced image signal, and the time high-band/space high-band signal are assumed to be a division result respectively.

Abstract: A lower hierarchical decoder (100) decodes lower hierarchical data (1001), and creates a prediction error signal (1004). A switch (107) accepts a decode hierarchical instruction signal (1100) indicating which of the upper and lower hierarchies a hierarchical image decoding device decodes, and switches a prediction decode processing. In case the lower hierarchy is decoded, the switch (107) inputs a lower decoded signal (1009) as an output to a prediction decode unit (105), and creates a lower hierarchical decoded image (1008). In case the upper hierarchy is outputted, the switch (107) inputs the lower decoded signal (1009) to a pseudo prediction decode unit (106), and creates a lower hierarchical decoded image (1009). An upper hierarchical decoder (200) inputs upper image data (2001), and creates an upper hierarchical decoded image (2008) with reference to the lower hierarchical decoded image (1009).
