Patent number: 5608730Abstract: There is disclosed a communication system using a bi-directional bus, which includes a plurality of devices (e.g., TV image receiver or video tape recorder, etc.) connected to each other. Each device includes a transmit signal formation unit having a frame structure including an address field for specifying addresses of devices between which communication is carried out, a control field for specifying whether communication is carried out in the state where device on the receiving side is locked or in the state where that device is unlocked, and a data field for specifying data to be transmitted. For transmitting data having a data quantity greater than data capacity of the data field, the data is divided into a plurality of frames, an indication to lock device on the receiving side is given to control field of a frame transmitted first, and an indication to unlock that device is given to control field of a frame transmitted last.Type: GrantFiled: December 17, 1993Date of Patent: March 4, 1997Assignee: Sony CorporationInventors: Yoshio Osakabe, Shigeo Tanaka, Akira Katsuyama, Hiroshi Yamazaki, Yasuo Kusagaya, Noriko Kotabe, Kouichi Sugiyama, Makoto Sato

Patent number: 5598278Abstract: Connection patterns as many as possible can be managed by less standard patterns. Connected states of a VTR (30), a VTR (40), a VTR (50), a VTR (60), an MDP (70), a tuner (80) and an AV center (100) composing a standard pattern are memorized in advance. A flag (N) representing the non-use is set to an AV equipment (e.g., VTR (60)) that is not used in actual practice of the AV equipments constructing the standard pattern. Therefore, a system in which a part of the AV equipments constructing the standard pattern is omitted can be managed similarly to the system of the standard pattern.Type: GrantFiled: July 22, 1994Date of Patent: January 28, 1997Assignee: Sony CorporationInventors: Shigeo Tanaka, Hiroshi Yamazaki, Noriko Kotabe, Kouichi Sugiyama, Makoto Sato, Akira Katsuyama, Yoshio Osakabe, Yasuo Kusagaya
