PROBLEM TO BE SOLVED: To provide a stream form compatibility determining system capable of always substantially and accurately determining the existence of a compatibility of a device to a stream form before the stream transmission.;SOLUTION: A controller 11 issues a compatibility determining command to DVCR 3 by a device control part 11b via an IEEE1394 bus 4. The DVCR 3 requests output of output stream form information from a response output part 22 in STB 2 by a request output part 32 when receiving the compatibility determining command. The DVCR 3 compares the output stream form information with input stream form information by a compatibility determining part 33, and retrieves the stream form compatible with the STB 2. When there is a compatible stream form, the controller 11 establishes the connection by a stream control part 11a.;COPYRIGHT: (C)2003,JPO
