ABSTRACT:
A system for delivering video data comprises a video server (1) including a video database (11) for storing video index information (13) defining a plurality of settings for a transfer bit rate of video data and indicating which data included in original video data (12) the video server should transfer to a client (2) through a network (3) when setting the transfer bit rate to one of the plurality of settings, a video data assembler (14) for extracting data from the original video data by referring to the video data index information so as to set the transfer bit rate to one of the plurality of settings, and for reassembling the extracted data to create video data to be transferred at the set transfer bit rate to the client, while maintaining consistency in contents of the original video data, and a video data delivery unit (15) for delivering a constant amount of data at certain intervals in accordance with the set transfer bit rate in order to transfer the video data reassembled by the video data assembler to the client. Furthermore, the video server comprises a network load sensor (17) for measuring a load imposed on the network.
