SEAMLESS ADDING OF REAL-TIME INFORMATION

摘要

A recorder seamlessly records real-time information, such as video and audio, on a record carrier in a track. The real-time information is encoded and multiplexed according to the required recording format. The recorder has an encoder status unit (50) for, while recording the real-time information, generating encoder status data (54, 55) and storing (56), in a status logbook, the encoder status data at log entry instants. The encoder status data represents the encoder and multiplexer status at respective log entry instant. When a recording of the real-time information is to be appended at an append point to pre-existing recorded real-time information, the encoder status data is retrieved from the status logbook. The log entry instant of the pre-existing recorded real-time information near the append point is selected. Before starting the new recording session, the encoder status at the append point is restored using retrieved real-time information (51, 52, 53) and the retrieved encoder status data (54, 55).
