1 General
1 .1 Scope
This part of IEC 61 834 specifies the content, format and recording method for the data blocks forming the helical records on the tape containing audio, video and system data. This part describes the specifications for the recording of single DVB programmes. The DVB data is delivered to the digital video cassette recorder via a digital interface or by a built-in tuner (IRD). The DVB data consist of an MPEG2 transport stream containing one or more programmes.
In DVB, the MPEG2 MP@ML is specified to encode the video signal. The maximum bit rate for the video signal is 1 5 Mbps. One programme may consist of one video bit stream or several audio bit streams and data bit streams.
Due to the varied bit rates of single DVB programmes,several recording modes are specifiedin order to make efficient use of the storage capacity of the digital video cassette recorder.
In addition to the normal play data stream of DVB recording, one or two special trick play datastreams may optionally be generated and recorded in the video area.
In this part 9, the data structure of a track is defined by APT = 000b which consists of fourareas as described in 4.3.2 of lEC 61834-1 and AP1 = AP3 = 000b.The data structure of MICis the same as in clause 10 of IEC 61834-2.
