Method and system for transforming compressed video traffic to network-aware ethernet traffic with A/V bridging capabilities and A/V bridging extensions

摘要

Aspects of a system for transforming compressed video traffic to network-aware Ethernet traffic with A/V bridging capabilities and A/V bridging extensions may include a graphics processing unit (GPU) that may enable encapsulation of compressed video data within a Display Port protocol data unit (PDU). A LAN subsystem may enable encapsulation of the Display Port PDU within an encapsulating PDU. The LAN subsystem may enable determination of a traffic class designation associated with the encapsulating PDU. The LAN subsystem may enable transmission of the encapsulating PDU via a network based on the traffic class designation. The LAN subsystem may also enable the encapsulation of compressed video data within Ethernet frames. A computing device, which receives the Ethernet frames may de-compress the compressed video data and send the uncompressed video data, which may be encapsulated within one or more Display Port mini-packets, to a multimedia monitor.

1. A method for transferring data in a data communication system, the method comprising:
extracting a Display Port protocol data unit (PDU) encapsulated within a networking or transport protocol received at a destination device via a network, wherein said Display Port PDU comprises an identifier that identifies whether auxiliary data or compressed video data is encapsulated within said Display Port PDU; when compressed video data and video data rendering instructions are encapsulated within said Display Port PDU based on said identifier, transmitting said Display Port PDU, without extracting the compressed video data from the Display Port PDU, to a multimedia monitor coupled to said destination device via a Display Port connector; when auxiliary data is encapsulated within said Display Port PDU based on said identifier, transmitting said auxiliary data, without extracting the auxiliary data from the Display Port PDU, to said multimedia monitor coupled to said destination device via an auxiliary channel of said Display Port connector, wherein said transmitting enables decompression of compressed video data contained within said Display Port PDU and rendering of resulting uncompressed video on said multimedia monitor.
