A multimedia data processing system and method which transparently processes video and/or audio streams in real-time. The operation of a system in accordance with an embodiment of the present invention does not require any intervention from, or involvement of, either the producer of the video and/or audio stream, or the client application. With such a transparent solution, video and/or audio streams can be processed seamlessly, and completely independently of the specific client application that the user chooses to use. In one embodiment, the invention uses an external service to monitor new processes and add code to these processes. The invention inserts into the system by hot-patching the software in memory and by only looking at select service calls.

System and method for transparently processing multimedia data

A camera comprises a camera support; a camera housing rotatably disposed on the camera support for pan movement relative to the camera support; a camera lens rotatably disposed in the camera housing for tilt movement relative to the camera housing; a pan motor coupled with the camera housing to drive the camera housing in pan movement relative to the camera support; and a tilt motor coupled with the camera lens to drive the camera lens in tilt movement relative to the camera housing.

Pan and tilt camera

A system and method for mechanically panning, tilting, and/or zooming a webcam to track a user's face. In one embodiment, such movement is controlled by kernel software in a host to which the webcam sends video data. In this way, a driver in the host kernel handles the face tracking, transparent to the application programs that would access the video. In an alternate embodiment, such movement is controlled by firmware in the webcam itself. The video and control signals are sent over the same standard cable, such as a USB bus. In one embodiment, the video is supplied to an instant messaging application. The use of a standard bus (e.g., USB) and the offloading of the face tracking to the webcam and driver allows easy use by the instant messaging application.

Mechanical pan, tilt and zoom in a webcam

An apparatus and method for intercepting messages between the bus controller and a device attempting to connect over the bus. Based on the intercepted message, the existing device using bandwidth can determine whether it can relinquish some of its bandwidth allocation while maintaining sufficient transmission quality. Thus, the already connected devices will make the determination if they can relinquish bandwidth, to allow a new device to connect.
