Abstract: The present document describes a system for installation in an operation room for providing a remote viewer/doctor with continuous visual access to the proceedings of a surgery (as a fixed target). The system comprises a camera comprising an internal processor for the processing of images/video, a moving platform on which the camera is provided, and pan and tilt motors for moving the camera head. A remote server sends pan/tilt commands for the pan and tilt motors and position commands for the moving platform to change positions. An external processor is provided at the system, which is dedicated to the processing of the pan and tilt commands without delay for panning and/or tilting the camera as the moving platform is changing positions at a rotating speed that allows the remote viewer to have un-interrupted visual access to the proceedings of the surgery.

Abstract: A method for providing a combined TV/PC video stream for TV display is provided. A TV video chip having a video input port for receiving a PC monitor display signal and an input for receiving a TV broadcast signal is provided, as well as a PC graphics chip. A PC monitor display signal is sent from the PC graphics chip to the TV video chip. The TV video chip mixing the PC monitor display signal with the TV broadcast signal to generate a combined TV/PC video stream in a format for TV display. A method for generating a combined TV/PC video stream in a format for TV display is further provided. A stream of encoded TV frames is received and the encoded frames are decoded to provide a stream of decoded TV frames. The stream of decoded TV frames is stored into a memory. A PC monitor display signal is provided and is converted into a stream of PC frames. The stream of PC frames are stored into the memory.

Abstract: A multimedia system is provided, comprising a computer for receiving audio data and video data from a source and transmitting the data serially over a high speed serial link, a set-top box connected through the link to the computer for receiving the audio data and video data, the set-top box having a southbridge module with a link interface connected to the link and providing a local parallel data bus output and at least one audio playback channel receiving the audio data; and a graphics processor receiving from the southbridge module the video data over the bus, processing the video data and providing a video output in at least one display format. At least one display device is connected to the graphics processor for receiving and displaying the video output; and at least one speaker is connected to the audio playback channel.
