Abstract
A content delivery system transmits content which is divided into a plurality of content blocks. The system includes a content server having a specifier to specify blocks associated with one or more ranges, and a transmitter to transmit the specified blocks according to a predetermined protocol. Each respective block has additional information attached indicating a common range for an attribute related to the content within the respective block. The system further includes a content receiver having a receiver to receive the content, a request range determiner to determine a request range of the content based on the attached additional information of each block by using block information indicating a length for each of the transmitted blocks, and a requestor to request the content associated with the determined request range from content associated with the one or more ranges.
