This systemaccepts content marker information including content identifier information for identifying content, and executes a process of causing a storing device to store the accepted content marker information. The systemaccepts sharing-user identifier information for identifying a user/users who shares/share the stored content marker information. The system: accepts a content marker output request that includes user identifier information for identifying a user and that is a request for an output of content marker information; based on the user identifier information included in the accepted content marker output request and the accepted sharing-user identifier information, extracts content marker information corresponding to the user identifier information from the stored content marker information; and outputs the extracted content marker information.

Content delivery system

This systemaccepts content marker information including content identifier information, and executes a process of causing a storing device to store the content marker information. The system accepts sharing-user identifier information for identifying a user/users who shares/share the stored content marker information. Upon acceptance of a content marker output request, the system transmits content marker information extracted based on the accepted sharing-user identifier information, to user equipment. Upon acceptance of the content transmission request based on the content marker information, the system determines whether to transmit content data to the user equipment based on stored viewing permission information.

Content delivery system where in a content marker information registered by one user may be viewed and/or requested by a user other than a specific user

A data receiving device which comprises a decoder which generates a plurality of decoded data based on 1) input data and 2) a plurality of pairs of control data and redundant data, in each the pair, the control data defining a selected encoding process and the redundant data being generated by the selected encoding process based on the control data and the input data, a selection control part which generates an error occurrence information based on information obtained from a medium through which the input data is received, and a selection part which selects output data from the input data and the plurality of decoded data based on the error occurrence information.

Data sending device, data receiving device, data sending method, and data receiving method

A video image coding apparatus which realizes appropriate allocation of an information amount to individual image divisions to reduce the difference in picture quality among different divisions of a decoded image. An input video image signal is into a plurality of image divisions by an image dividing section, and the image divisions are compressed coded by a plurality of coding sections. Resulting compression encoded data are multiplexed by a multiplexing section re-construct compression encoded data, and the compression encoded data are outputted as a compression stream. A coordinated coding control section receives some or all of coding parameters, image status parameters and coding result parameters of the coding sections and adjusts the parameters to be used for compression encoding by the coding sections in a control period or under a control condition determined in advance.
