    摘要: A digital signal recording apparatus for recording digital signal in synchronization blocks includes a generator for generating a synchronization pattern for indicating the beginning of each synchronization block, a generator for generating an ID data for indicating the sequence of the synchronization blocks, a generator for generating an ID parity for checking the ID data, a generator for generating additional information signal, which is a track width data, a generator for generating audio and video signals. Above data are applied to a pattern generator for generating track data comprising plural consecutive normal synchronization blocks immediately preceded by two mini-synchronization blocks and immediately followed by one mini-synchronization block. Each mini-synchronization block includes the synchrionization pattern, ID data, ID parity, and additional information signal. Each normal synchronization block includes the synchronization pattern, ID data, ID parity, and audio and video signal.

    摘要: A data transmission apparatus for conveying proper timing information to the destination application without embedding such information in transmission data packets. Particularly, the apparatus comprises a timing component for generating and inserting additional timing information into the header at least first packet of each frame of the data stream for transmitting to a destination node. The apparatus further comprises a receiving device for extracting the additional timing information from the transmission path header and inserting the additional timing information to data packets to be sent to application. The application utilizes the added timing for processing the received data simultaneously.
