Abstract
A content delivery system includes a content transmission apparatus that includes at least one processor configured to implement stored instructions and execute a plurality of tasks. The plurality of tasks include a compression task, a transmission task, and a reception task. The compression task performs compression of content dividing thereof into a fundamental component and an extended component. The transmission task transmits content to a client apparatus. The reception task receives a retransmission request for the content. The transmission task determines, depending on a communication condition, whether to transmit the fundamental component of the content or both the fundamental component and the extended component of the content together. The transmission task, upon the reception task receiving the retransmission request, retransmits only the fundamental component of the content that corresponds to the retransmission request.
