摘要： PROBLEM TO BE SOLVED: To prevent a load from being concentrated particularly on a line of a network between a server and a video playback device of a viewer, in a system for receiving distribution of video by a network. SOLUTION: Even if contents of which the time and date for the contents to be regularly provided to a viewer are determined, the contents are allowed to be downloaded from a user in advance. Then, the encrypted contents are distributed, a key for decoding is requested from a video playback device when the viewing-enabling date and time come, and a content distribution server for providing the contents transmits the decoding key to the video playback device. In the video playback device, the encrypted contents are allowed to be decoded and played back by the decoding key. When the user has downloaded the contents in advance, a discount rate is applied.

摘要： PROBLEM TO BE SOLVED: To solve the problem that although there are many devices having functions of displaying states of progress of download, among devices which download content via networks, the functions merely perform simple display of progress of download by using the ratio of a received content size to the size of reception-object content, consequently not providing users with sufficient information.
SOLUTION: An information-processing device 300 equipped with a downloading function manages: a table that manages states of download; and download-controlling meta files 120 which describe content-related information necessary for downloading one or more contents. Management information on the table is correlated with information that the download-controlling meta files 120 have, to provide users with the information that the download-controlling meta files 120 have, at the time of displaying the states of the progress, and consequently the display of the progress for the respective download-controlling meta files 120 is achieved.
