SYSTEMS AND METHODS OF ASSEMBLING AN ELEMENTARY STREAM FROM AN ENCAPSULATED MULTIMEDIA TRANSPORT STREAM

摘要

Systems and methods of assembling an elementary stream from an encapsulated multimedia transport stream are disclosed. An exemplary method includes: receiving a command from a user mode video playback component; in response, processing layer-2 packets received through a network interface driver binding to assemble, into an MPEG elementary stream, multimedia transport packets encapsulated within; and supplying the stream to a decoder. The receiving and processing steps are performed in kernel mode. Also disclosed is an exemplary digital home communication terminal that includes a network interface, memory, and a processor. The processor executes code to: receive a command from a user mode video playback component; process layer-2 packets received through a network interface driver binding, in order to assemble into an MPEG elementary stream multimedia transport packets encapsulated within the received layer-2 packets; and supply the elementary stream to a decoder. The receive and process operations are performed in kernel mode.
