Method and apparatus for recording a signal

摘要

The invention relates to a system for recording a signal. A recorder ( 200 ) comprises a receiver ( 201 ) for receiving a source signal ( 101 ) having associated first play time information such as a Normal Play Time timeline. The receiver ( 200 ) is coupled to a recording controller ( 203 ) which generates a recorded signal ( 301 ) from the source signal ( 101 ). The recorded signal ( 301 ) comprises a recording discontinuity with respect to the source signal ( 101 ) caused by for example the recording being paused in a time interval. The recording controller ( 203 ) is coupled to a storage medium ( 205 ). The recorder ( 200 ) further comprises a time processor ( 209 ) for generating second time information for the recorded signal ( 301 ) in response to the first play time information and the recording discontinuity. The second time information may for example be a compensated NPT timeline or event descriptors or stream events having time indications modified to correspond to the recorded signal ( 301 ).
