Definitions
- a simpler way of detecting the program clock reference signals is carried out, namely by not using the program allocation table and the program map table, but simply by checking every packet that passes by for the presence of a program clock reference signal.
- One of the program clock reference signals of the programs selected for recording will be chosen, namely that one program clock reference signal that has been detected first.
- the program clock reference chosen for generating the time stamps during recording of the programs is an arbitrary one of the program clock references corresponding to the programs selected for recording.
- the length of the adaptation field can be variable. Therefore, the adaptation field comprises a word AFL, indicating the adaptation field length.
- the adaptation field length word AFL is the first byte in the adaptation field.
- the adaptation field AF comprises a flag, denoted 'PCR flag' (program clock reference flag), at a specific fixed position in the adaptation field.
- recording of the various datastreams is realized using time stamps generated on the basis of the PCR signals retrieved from the datastream having the PID number 110.
- block 50 the recording of the transport stream shown in (a) of figure 1 is started.
- a packet is inputted in the retrieval unit 14, block 52 in figure 5.
- the retrieval unit 14 looks for the presence of a PCR signal in the packet, and if not, the program returns to block 52, by inputting the next packet. If so, see block 54, the PID value comprised in the packet is retrieved, block 56, and stored in the memory 26, block 58. Further, the PCR value is retrieved from the packet, block 60.
- the next packet is inputted, block 62. If a PCR signal is present in the packet, see block 64, and the PID of the packet equals the PID value stored in the memory, see block 66, the PCR signal is retrieved from the packet, see block 60. If no PCR value is present in the packet, see block 64, or if the PID value is not the same as the PID value stored in the memory 26, the program returns to block 68.
