Abstract:
An apparatus for recording a first and a second digital information signal in tracks on a record carrier, the first and second digital information signals comprising subsequent packets of information, the apparatus comprising:input means for receiving the first and second digital information signals; signal processing means for processing the first and second digital information signals into a first recording signal and a first trick play signal, respectively, suitable for recording in the tracks on said record carrier, the signal processing means generating sync blocks of information, each sync block comprising a first block section having a synchronization signal and a second block section having a number of information bytes, the signal processing means further storing, each time, the information included in x transport packets of the first digital information signal in the second block sections of y first sync blocks, the second block section of at least the first sync block of the group of y first sync blocks comprising a third block section for storing a time stamp, the signal processing means further storing, each time, the information included in x transport packets of the second digital information signal in the second block sections of y second sync blocks, the second block section of at least the first sync block of the group of y second sync blocks comprising a third block section for storing a time stamp; time stamp generator means for generating a time stamp, the time stamp generator means comprising counter means for generating subsequent cycles of count values, the signal processing means storing a time stamp generated by the time stamp generator means for a corresponding packet in the third block section of a sync block, and combining the first and second sync blocks into a composite signal; and writing means for writing the composite signal in the tracks at a predetermined recording speed of the record carrier, the writing means comprising a first and a second write head positioned on a rotatable head drum, said first write head having a first azimuth angle and said second write head having a second azimuth angle different from the first azimuth angle, the first digital information signal being meant for reproduction in a reproduction apparatus at a reproduction speed which is equal the recording speed, the second digital information signal being meant for reproduction at a trick play speed which is equal to n1 times said recording speed, where n1 is a positive integer larger than 1, characterized in that the counter means in the time stamp generator means comprises first counter means for generating subsequent cycles of first count values so as to supply time stamps for said first digital information signal, and second counter means for generating subsequent cycles of second count values so as to supply time stamps for said second digital information signal, said first counter means supplying said first count values at a first rate, said second counter means supplying said second count values at a second rate, which equals said first rate divided by n1.
