PIPELINED ENCRYPTION AND PACKETIZATION OF AUDIO VIDEO DATA

摘要

A system for pipelined encryption and packetization of audio video (AV) data may consecutively encrypt a number of AV data units based on a security mechanism, associate the encrypted AV data units with a security header, where the security header is generated before the AV data units are encrypted, and the security header includes information related to the security mechanism, generate network packets for transporting the encrypted AV data units and the associated security header based at least in part on an order in which the AV data units are encrypted, where one or more of the network packets is generated contemporaneous with encrypting one or more of the AV data units, and provide the network packets for transport to a client device as the packets are generated, where the AV data units are encrypted and the network packets are generated without accessing memory external to the system.

主权项

1. An integrated circuit for processing audio/video (AV) data, the integrated circuit comprising circuitry configured to:
encrypt a first received AV data unit; generate a first network packet for the first encrypted AV data unit at least partially contemporaneous with encryption of a second AV data unit by the integrated circuit; provide the first network packet for transport over a network; and encrypt the first received AV data unit at least partially contemporaneous with generation of a second network packet by the integrated circuit; wherein the first and second AV data units are encrypted and the first network packet is generated without accessing memory external to the integrated circuit.
