Abstract
A system and method are provided for encoding and decoding multiplexed video signals to de-jitter the content. A first de-jitter operation is performed on incoming signals and a second de-jitter operation is performed on PCR modified outbound packetized signals after sequencing of the packetized signals has been determined. In one case the second de-jitter operation can be performed using a PLL that is based, at least in part, on the output hardware limitations.
Claims10
A method comprising:
- receiving a plurality of input signals each comprising a plurality of packets;
- performing a first de jitter operation on each of said plurality of input signals;
- determining a sequence for positioning said plurality of packets from each of said plurality of input signals into a multiplexed signal;
- determining whether any of said plurality of input signals is to be positioned incorporating a program clock reference;
- applying a program clock reference correction to each input signal that is to be positioned incorporation said program clock reference;
- performing a second de-jitter operation on each of said input signals to which said program clock reference correction is applied;
- and
- combining said plurality of packets of each of said input signals based at least in part on said sequence for positioning.
