Abstract
Method and apparatus for carrying out the method receiving packets, each of the packets comprising a header and a payload. For a particular packet among the packets, the method includes processing at least the header of the particular packet to determine a flow associated with the particular packet; attempting to determine a payload structure based on the flow, the payload structure associated with transport of coded video data in the payload of the particular packet; and if the attempting is successful, repackaging coded video data contained in the payload of the particular packet into a new packet and forwarding the new packet to an external system or storing the new packet in memory.
Claims56
A computer-implemented method, comprising:
- receiving packets, each of the packets comprising a header and a payload;
- for a particular packet among the packets:
- processing at least the header of the particular packet to determine a flow associated with the particular packet;
- attempting to determine a payload structure based on the flow, the payload structure associated with transport of coded video data in the payload of the particular packet;
- if the attempting is successful, repackaging coded video data contained in the payload of the particular packet into a new packet and forwarding the new packet to an external system or storing the new packet in memory;
- wherein the flow associated with the particular packet is the same as the flow associated with other ones of the received packets and different from the flow associated with still other ones of the received packets.

A computing device comprising:
- a computer-readable program storage unit comprising an application program and an operating system code;
- and
- a processor being configured to read and execute the application program so as to carry out a method that comprises:
- receiving packets, each of the packets comprising a header and a payload;
- for a particular packet among the packets:
- processing at least the header of the particular packet to determine a flow associated with the particular packet;
- attempting to determine a payload structure based on the flow, the payload structure associated with transport of coded video data in the payload of the particular packet;
- if the attempting is successful, repackaging coded video data contained in the payload of the particular packet into a new packet and forwarding the new packet to an external system or storing the new packet in memory;
- wherein the flow associated with the particular packet is the same as the flow associated with other ones of the received packets and different from the flow associated with still other ones of the received packets.

A computer-readable medium storing computer-readable instructions which, when executed by a processor, cause the processor to carry out a method that comprises:
- receiving packets, each of the packets comprising a header and a payload;
- for a particular packet among the packets:
- processing at least the header of the particular packet to determine a flow associated with the particular packet;
- attempting to determine a payload structure based on the flow, the payload structure associated with transport of coded video data in the payload of the particular packet;
- if the attempting is successful, repackaging coded video data contained in the payload of the particular packet into a new packet and forwarding the new packet to an external system or storing the new packet in memory;
- wherein the flow associated with the particular packet is the same as the flow associated with other ones of the received packets and different from the flow associated with still other ones of the received packets.
