Patent ID: 8191101

Claim:
A method of producing low-cost video storage and delivery system that manages jitter in a cost effective manner, the method including: at a storage unit, receiving a plurality of Ethernet encapsulated blocks of MPEG transport packets that belong to a program stream, and storing at least part of the packets in storage locations across a plurality of disks that correspond to arrival times of the packets that belong to the program stream; retrieving the packets from the storage locations across the plurality of disks and sending the Ethernet encapsulated packets to an EdgeQAM unit at times based on the storage locations that correspond to the arrival times of the packets at the storage unit; at the EdgeQAM unit, receiving the Ethernet encapsulated packets, buffering at least the MPEG transport packets, and finding in the MPEG transport packets a plurality of PCR time stamps; using a first reference clock of the EdgeQAM, scheduling the MPEG transport packets for transmission at times relative to the PCR time stamps and the first reference clock, without recovering an encoder clock used to generate the PCR time stamps; and transmitting the MPEG transport packets via a QAM channel to a receiving device.
