Data transmission system, receiving apparatus, and receiving method as well as sending apparatus and sending method

摘要

A data transmission system has a sending apparatus that sends streaming data, and a receiving apparatus (114) that receives the streaming data and transmits a request of switch of the streaming data to the sending apparatus, in which the sending apparatus switches the streaming data in response to the received request. The receiving apparatus (114) includes a receiving section (252b), a storage section (253) that stores the streaming data temporarily and transfers it, an operation-detecting section (115) that detects whether a user operates the request, and a control section (251) that controls a transfer rate of the streaming data stored in the storage section (253) to fast-forward the streaming data when the operation-detecting section (115) detects that the user operates the request of switch of the streaming data. The sending apparatus includes an information-adding section that adds to the streaming data additional information on the user's operation when receiving a notice of user's operation, and a sending section that sends the additional-information-added streaming data.
