Abstract: Peer-to-peer video streaming software that takes video from a host's Graphical Processing Unit (GPU), moves it to the encoder, manages the color conversions, moves the video into the networking software, and in turn manages the video on a client. This software also handles the inputs from the client and tells the host how to react to the client's inputs. In executing the video streaming, the host broadcasts and renders the video that is or will be streamed. It encodes the video frame with a hardware encoder that is part of the GPU to eliminate latency associated with transferring frames to the central processing unit (CPU). The host transmits compressed video and audio data to the client, and the client uses its hardware decoder and the video streaming software to render the video. The client sends mouse, keyboard, joystick, and controller signals to the host, which varies the bit rate based on the network connection.

Abstract: Multiple video picture frames are combined into a spatial multiplex video picture frame that may be fully decoded and displayed. The video display of the spatial multiplex video picture frame is a composite combination of all of the video picture frames that have been combined, and may have an appearance such as a mosaic.

The headers of the individual components are altered to become slice based, such as in accordance with the ITU-T H.263 video standard, prior to establishing the slice based picture position if the frames are not already of the slice format.
