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. A capacity of the synchronization buffer is smaller than a capacity of the transmission buffer, because of that a selected data from the packet 6 is stored in this buffer only.
