    摘要: In a case of recording and managing a program which has a plurality of image streams in one program, it is necessary to address which stream a logic table which records a position of an I picture for high-speed fast forwarding and rewinding corresponds to.In a recording method which records a digital broadcast, in particular one method is provided which records and manages the program which has the plurality of image streams in one program.In the case in which there are a plurality of image streams in one program, as information which indicates which stream the logic table of the I picture, for carrying out the fast forwarding and rewinding operations quickly, corresponds to, a component tag fixed by a European or Japanese digital broadcast standard is recorded with the logic table. Also, in the event of recording an American broadcast stream, in digital broadcast standards of which there is no component tag regulation, a value of a program map table (PMT), which indicates one of the plurality of streams, is recorded.

    摘要: A recording method of recording received digital broadcasting on a medium, wherein a stream other than first and last portions is recorded with a predetermined number of recording packets, and the number of recording packets of the first and last portions of an AV stream file is recorded as management data. This method, which records an AV stream basically with a specified number of recording packets in order to improve the performance of access to a medium, thereby makes it possible to improve the splitting accuracy when the user splits a program, overcoming a restriction caused by the specified number of recording packets.

    摘要: It is an object of the present invention to protect a copyright of a content by suppressing creation of illegal copies of the content and prevent a content from being transmitted beyond a range of personal use in a process to transmit the content through a wire or wireless LAN. Before transmitting a content from a content transmission apparatus to a content reception apparatus, the content transmission apparatus and the content reception apparatus authenticate each other. In the authentication, a timer measures a time interval between a transmission of an authentication request and a reception of an acknowledgement of a reception of the request or between a transmission of a response to a received authentication request and a reception of an acknowledgement of a reception of the response. If the time interval does not exceed an upper limit, a content encrypted by using a shared key is transmitted from the content transmission apparatus to the content reception apparatus, and the address of the content reception apparatus as well as apparatus information unique to the content reception apparatus are cataloged in the content transmission apparatus. Thus, in order to transmit another content, the content is merely encrypted prior to the transmission without measuring a time interval.
