Method and system for utilizing a/v bridging and a/v bridging extensions to replace display port, hdmi, dvi and/or analog ports on a personal computing system

Method and system for utilizing a/v bridging and a/v bridging extensions to replace display port, hdmi, dvi and/or analog ports on a personal computing system description/claims

This application makes reference to, claims priority to, and claims the benefit of U.S. Provisional Application Ser. No. 60/917,870, filed on May 14, 2007, which is hereby incorporated herein by reference in its entirety.

This application makes reference to U.S. patent application Ser. No. 11/832,807, filed on Aug. 2, 2007, which is hereby incorporated herein by reference in its entirety.

Certain embodiments of the invention relate to communication networks. More specifically, certain embodiments of the invention relate to a method and system for utilizing A/V bridging and A/V bridging extensions to replace Display Port, HDMI, DVI and/or analog ports on a personal computing system.

High end graphics and/or high definition video that is received and/or stored at a computing device may be displayed on an attached video monitor. In many cases the video monitor is physically separate and has been conventionally attached to the computing device via an analog interface, such as a video graphics array (VGA) interface, or a digital interface such as a digital visual interface (DVI). In a typical configuration, an interface in the computing device is connected to a compatible interface in the video monitor via an interstitial connector, such as a cable.

In an alternative configuration, the computing device may incorporate a video monitor. An example of this configuration is a laptop computer in which the video monitor is a component in the physical computing device unit. Whether the video monitor is physically incorporated within the computing device or is a physically separate device, the video monitor may or may not have touch screen capability.

The high definition multimedia interface (HDMI) is a digital interface standard that enables a video player device, such as a DVD player, to send high definition video data to a display panel device, which displays the high definition video data. The video player device and the display panel device may communicate via a connecting HDMI cable. HDMI describes a point-to-point interface, which is capable of transmitting data from the video player device, which is connected at one end of an HDMI cable, to the display panel device, which is connected to the other end of the HDMI cable.

Display Port is a digital interface standard, which enables a computing device to send graphics and video data to a video monitor, or multimedia display device, via a Display Port interface. In this regard, the Display Port interface standard may describe a point-to-point interface, which is capable of transmitting data from a device connected at one end of a connecting cable to a device connected at the other end of the connecting cable. The graphics and/or video data communicated across the Display Port interface may be sent in mini-packets as described in applicable standards. The mini-packets may contain information comprising instructions on how to render the graphics and/or video data on the video display screen, for example. The mini-packets may be sent via a plurality of data paths referred to as “lanes”. In an exemplary Display Port interface, there may be four (4) such lanes.

In addition to supporting unidirectional data traffic from the computing device to the computer monitor (or other attached video display device), the Display Port standard may also enable the bidirectional transfer of data. For example, the Display Port standard may allow for the exchange of encryption keys to enable the transfer of encrypted digital data across the Display Port interface. This capability may enable protection of digital content transferred across the Display Port interface.

A Display Port interface at a device comprises a connector into which may be inserted one end of a Display Port connecting cable. The connector may comprise a plurality of pins and/or slots, which may be utilized to enable the device to transmit and/or receive data-containing signals via the Display Port lanes. A physical layer (PHY) defined for the Display Port standard may specify signal levels and/or signal durations, which may be utilized to encode data transmitted and/or received via the Display Port interface.

Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present invention as set forth in the remainder of the present application with reference to the drawings.

A method and system for utilizing A/V bridging and A/V bridging extensions to replace Display Port, HDMI, DVI and/or analog ports on a personal computing system, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.

These and other advantages, aspects and novel features of the present invention, as well as details of an illustrated embodiment thereof, will be more fully understood from the following description and drawings.

FIG. 1 is a diagram illustrating an exemplary system for Display Port to Ethernet replacement, in accordance with an embodiment of the invention.
