Abstract: A dual transceiver architecture provides source and sink device capabilities for communicating visual information between information handling systems and displays. A detector determines whether a cable connected to a port provides visual information or receives digital information. If visual information is received at a port, the visual information is provided to an adjacent port through a dual transceiver architecture so that the visual information is available to forward to another display, information handling system or other device. A common connector configuration simplifies the connection of multiple displays or devices, such as in a daisy chain configuration.

Abstract: A visual tree structure as specified by a program is constructed and maintained by a visual system's user interface thread. As needed, the tree structure is traversed on the UI thread, with changes compiled into change queues. A secondary rendering thread that handles animation and graphical composition takes the content from the change queues, to construct and maintain a condensed visual tree. Static visual subtrees are collapsed, leaving a condensed tree with only animated attributes such as transforms as parent nodes, such that animation data is managed on the secondary thread, with references into the visual tree. When run, the rendering thread processes the change queues, applies changes to the condensed trees, and updates the structure of the animation list as necessary by resampling animated values at their new times. Content in the condensed visual tree is then rendered and composed. Animation and a composition communication protocol are also provided.

Abstract: A method and apparatus for a digital video display. A digital display device receives an analog signal representing an image formed of pixels in video lines and a signal containing a synchronization waveform for the image. An analog-to-digital converter (ADC) receives the analog signal and converts it to a sampled digital waveform.
