摘要： To realize a system which can efficiently use a satellite communications or broadcasting channel and simply realize modes suitable for applications such as shopping, wherein the system also has a large-scale subscription. A system was configured wherein for information sent from a satellite the header of a packet is deemed as an information identifier based on the content of the information, or alternatively information having a receiving terminal identifier provided beforehand to the receiving terminal is combined with information having an information identifier based on the content of the information.

摘要： When only part of content that is stored inside a terminal is updated, the updated content is allowed to be received efficiently, taking into account reducing the power consumption of the terminal. This broadcast content delivery apparatus (10) has a program information generating apparatus (15) that generates program information including a list of objects constituting the broadcast content, object identifiers, object version number information, and object broadcast times, and a content delivery control apparatus (12) that repeats transmitting the objects based on the object broadcast times, and transmits the program information at a predetermined transmission time, when there is addition, removal or updating with respect to the objects constituting the broadcast content, the program information of the broadcast content is updated, the updating of the objects is reported to a broadcast content receiving apparatus by updating corresponding object version number information, and the addition or removal of the objects is reported to the broadcast content receiving apparatus by updating the object list.

摘要： Provided is a broadcast supplemental data transmission device, a broadcast supplemental data transmission method, and a broadcast system that can reduce the traffic of a communication network as much as possible at the time of supplementing missing data in broadcasted content data. When “GET HTTP/1.1 If Unmodified Since Time Information”, which is a request for retransmission of missing data containing time information, is received from a receiving device, an HTTP response module determines whether there is rebroadcast of contents containing missing data based on the time information contained in the request for retransmission. When it is determined by the HTTP response module that there is rebroadcast, “412 Precondition Failed”, which is one of error notifications, is transmitted as a response to the receiving device, and the transmission of the contents through a communication network is not performed.
