Abstract
Official abstract text for this publication.
Method to enable a local system time clock counter (STC) of a receiving recording device to lock to program clock reference (PCR) information comprised in a received real time sequence of information signal packets, such as MPEG2 Transport Stream packets. The method comprising determining the number of cycles between arrival of the first information signal packet and the arrival of the information signal packet comprising the first Program Clock Reference (PCR) information. This information is stored as an attribute of the stored sequence.
First claim
Opening claim text (preview).
The invention claimed is: 1. Apparatus for recording a real time sequence of information signal packets (TS packet) comprising A/V information, on a record carrier, the sequence comprising at intervals of multiple information signal packets, Program Clock Reference (PCR) information for locking a local System Time Counter (STC) to a clock at a transmitting site, the apparatus comprising: receiving means for receiving the information signal packets, a local System Time Counter (S…
