A handsfree video phone system includes a video phone terminal and a car device in which a microphone, a speaker, and a camera are connected with an instrument panel via a cable. The video phone terminal is connected with the instrument panel via a wireless communication medium. When the video phone terminal is brought into the vehicle, the instrument panel informs the video phone terminal of the attribute information on the system structure. According to the attribute information, the video phone terminal switches the paths of multiplexed audio-video data so as to replace a microphone, a speaker, a camera, and a display that have been built in the video phone terminal with the microphone, the speaker, the camera, and a display of the instrument panel when the status changes to the communication status.

Digital data transmitter, transmission line encoding method, and decoding method

A ring-shaped network quickly performs initialization even when a plurality of data transmission apparatuses are connected thereto. Each data transmission apparatus outputs received data to a device connected thereto while performing establishment of clock synchronization based on the received data, and when synchronization is established, it resends the received data. Further, when synchronization of the connected device is established, it sends data supplied from the connected device. Further, a master data transmission apparatus outputs data at turn-on of power or immediately after reset, and a next-stage slave data transmission apparatus receives the data to establish synchronization, and resends the received data when synchronization is established. Thus, synchronization of all the data transmission apparatuses is established while making a round of this data, and then synchronization of devices connected to the respective data transmission apparatuses is established.

A first initialization pattern signal is a signal in which a maximum signal level and a minimum signal level appear alternately, and a second initialization pattern signal is a signal in which all signal levels appear in a predetermined arrangement. In a ring-shaped network including plural stages of data transmission apparatuses (), a transmission unit () of each data transmission apparatus outputs the first initialization pattern signal successively to a next-stage data transmission apparatus at turn-on of power or immediately after reset, and a reception unit () establishes clock synchronization on the basis of the first initialization pattern signal received. When synchronization is established in all of the data transmission apparatuses, the transmission unit () outputs the second initialization pattern signal successively to the next-stage data transmission apparatus, and the reception unit () sets evaluation levels for the respective signal levels on the basis of the received second initialization pattern signal, and transmission/reception of data is started when evaluation levels are set in all of the data transmission apparatuses.

A control device determines whether an image generated by merging several concurrently picked-up images has consistent image quality on a display device. If determined No, image quality parameters set in each image pickup device are so controlled as to make the image quality of the merged image consistent. Therefore, the merged image can assuredly have consistent image quality. Further, a signal processing device detects, based on positions of nodes and attributes of cameras, a connection indicating which node is connected to which camera and with what attribute. The signal processing device in advance stores every detectable connection and a plurality of image processing programs corresponding to each connection, and selects and carries out one of the image processing programs corresponding to the detected connection.

There is provided a transmission system which realizes more flexible resource allocation. A resource management means upon receipt of a resource allocation request including a minimum bandwidth and a maximum bandwidth, reduces allocated resources stored in an allocated-resource request table to the corresponding minimum bandwidths. As such, the request is accepted with higher probability. When releasing an allocated resource, the resource management means increases the allocated-resources of the allocated-resource requests to bandwidths within a range of the corresponding maximum bandwidths. Accordingly, the resources are utilized more effectively. When releasing the resource, the resource management means notifies, by broadcast, all the communication apparatuses that free resources are increased. Thus, for the communication apparatus whose request has been rejected, the resource is allocatable.
