Method for networking video output by collaborating hardware components

Disclosed is a method for networking video output by collaborating hardware components. Benefits include improved functionality, improved performance, and improved cost effectiveness.

General description

              The disclosed method is networking video output by collaborating hardware components.

              The key elements of the disclosed method include:

•             Remote administrator

•             Access software

•             Computer management

•             Redirection network service

•             Network adapter

•             Network access

Advantages

              The disclosed method provides advantages, including:
•             Improved functionality due to providing video redirection when the OS is not available
•             Improved functionality due to enabling remote customer and administrative support

•             Improved functionality due to offloading the processing function to collaborating hardware components

•             Improved performance due to offloading function from the central processing unit (CPU) to  the collaborating hardware components

•             Improved cost effectiveness due to eliminating the requirement for special logic or components that convert an analog/digital signal to a byte stream of data

Detailed description

              The disclosed method is networking video output by collaborating hardware components. A computer with network access is managed by a remote administrator using access software (redirection network service). It connects to the managed computer and registers for the redirection of video/keyboard and mouse messages. The protocol is either standard or customized by a video adapter manufacturer (see Figure 1).

              The managed computer must contain the following components (see Figure 2):

•             Redirection network service

•             Video adapter

•             Network adapter

•             Network access

Redirection network service

              This component delivers update messages between the managed computer and the remote administrator. The redirection network service can be implemented as a component within a network adapter. However, it may be placed on the chipset (in case of several network interfaces).

              The redirection network service has the following components/capabilities:

•             Bus access protocol extensions receive messages sent by the video adapter and inject commands to the keyboard and mouse.

•             Transfer stack communicates with the remote administrator. The stack may contain an optional authentication/encryption layer

Video adapter


This component has the following components/capabilities:

•             Bus access protocol extensions are used by the video adapter for sending messages to the redi...
