Abstract: When transmitting encoded video data and audio data, a transmitter 201 also transmits a decoding method 107 generated by decoding-method generation means 203. In the case of a receiver 202, decoding control means 111 controls decoding means 208 in accordance with a received decoding method 113 and thereby, decodes video data and audio data 115. Thus, it is unnecessary for the receiver 202 to previously prepare all of a plurality of decoding methods and the transmitter 201 does not need to encode video data or audio data in accordance with the decoding method owned by the receiver 202.

Abstract: A transmission medium connecting device is used for connecting multiple bus type transmission media. The connecting device includes an apparatus information list containing information related to apparatuses connected to the bus type transmission media. The connecting device collects the apparatus information of each of the apparatuses, and prepares the apparatus information list. Also included are a packet receiver for receiving a packet transmitted from the transmission media and a packet transmitter for transmitting a packet to the transmission media. An apparatus connected to the bus type transmission media may request access to the apparatus information list and read out information from the apparatus information list regarding another apparatus to be communicated with.

Abstract: Disclosed is a packet transmitting/receiving apparatus that receives a response packet to a transmitted request packet without fail. When a request packet is transmitted by a packet transmitter, a prediction of a response packet is made in reply to the transmitted request packet. When the response packet is received from a transmission medium, a comparator compares a portion of the packet received by a receiver with a portion of the packet and, only when they match, outputs the received packet. In this way, the expected response packet is received without fail. This enhances the reliability of the transmission medium.

Abstract: It is objected to simplify a procedure concerning bandwidth acquisition. Bandwidth acquiring means 809 of a second transmitting apparatus 814 acquires a bandwidth which was used by a first transmitting apparatus 806 by using a propagation delay identifier 804 read from first transmitting apparatus 806 and a maximum transmission data size 805 after stopping transmission of first transmitting apparatus 806. Each apparatus is composed so that transmission is started using this bandwidth and because returning and re-acquisition are not accompanied when the transmission is switched, necessary procedure can be simplified. Further, it is possible to effectively use the bandwidth by using a propagation delay identifier.

Abstract: A serial bus control apparatus is disclosed. The apparatus includes a device for providing a reservation control table for reserving a transmission bandwidth and a transmission channel used at a future time on a serial bus. The reservation control table is organized such that transmission of data of certain bandwidth and channel at a certain future time can be reserved for a transmission between arbitrary nodes. The reservation control table is stored and controlled on a first register. The register is accessible for reading and writing from an arbitrary node on the serial bus. The apparatus may further include a detection part to detect present time and a second and third register for securing available transmission bandwidth and channel at present time. By having this reservation control table, it becomes possible for each node on the serial bus to secure transmission of data of certain bandwidth and transmission channel in a desired future time.

Abstract: The invention has an object to provide a digital VCR with a packet communication interface to a packet communication bus, which VCR can be used for reproduction, recording and editing in which image signals from two or more reproduction VCRs are mixed. A synchronization buffer is provided in the interface in which a data in accordance with synchronizing data which is contained in a packet 6 is stored. Image signal data received from the bus or to be transmitted to the bus is stored in a separate transmission buffer. The VCR can be switched between different modes in which the direction of synchronization data flow (from the bus or to the bus) and image signal data flow can be selected independently of one another. Data for storing in the synchronization buffer is selected from the packet 6 by controlling of an external synchronization controller.

Abstract: The transmitting device latches the time of the absolute clock when the V-sync signal of the video signal block is transmitted, adds to the latched time a predetermined delay time equivalent to the sum of the time required for the transmitting device to process the video signal block and the time required for the transmittance; and transmits the resulting sum value together with the video signal block. The receiver extracts the sum value and produces the V-sync signal delayed by said predetermined delay time.
