A method and apparatus for controlling a video surveillance display comprising receiving an MPEG video stream comprising video data in I-frames and P-frames, storing the MPEG video stream in an input buffer, displaying the stored MPEG video stream in full-motion video, monitoring the amount of video data stored in the input buffer; and displaying only the I-frames of the stored MPEG video stream when the amount of video data stored in the input buffer is greater than a predetermined amount.

Method and apparatus for controlling a video surveillance display

An apparatus for and method of storing video data comprising receiving an MPEG video stream comprising I-frames and P-frames, separating the I-frames from the P-frames, storing the I-frames and the P-frames separately, and providing information so that the I-frames and the P-frames can be combined to produce a full-motion video.

Apparatus and method of storing video data

Embodiments of the present invention include systems, methods and apparatus for amplifying a composite video signal transmitted over long distance unshielded twisted pair cabling. The apparatus and system may include a plurality of amplifiers, an analog switch, and a control unit. The control unit generates a configuration signal to enable the output of one or more amplifiers (which may be serially connected) and configure the analog switch. A user input may be provided for manually configuring the amplifiers and analog switch. When the video signal is a color signal, the control unit may automatically configure the amplifiers and analog switch with reference to the amplitude of the color burst.

Line tapping method of video amplification for unshielded twisted pair active receiver

A method of compensating for the movement of a video surveillance camera comprising the steps of moving an interlaced camera, capturing a first video field of a frame at a first point in time, capturing a second video field of a frame at a second point in time, determining the speed at which the camera is moving, and shifting the relationship between the first and second video fields based on the period of time between the first point in time and the second point in time and the speed at which the camera is moving.

Disclosed is a method and apparatus for transmission of audio signals over a dedicated video transmission line in which the analog audio signal is inserted into and becomes a part of the video signal. Samples of the audio signal are inserted into the active video line, either at the beginnings or endings, or both, of each active video line scan signal. A defined amount of the active video interval is reserved from the active video line, and is replaced with samples of the analog audio signal. An analog switch in the modulator of the invention toggles to pick up the samples of audio and place them at the designated location (either at the beginnings or at the ends) of each active video line scan signal. A corresponding switch in the demodulator of the invention toggles to retrieve the audio samples from the active video line scans for output to the user. Stereo and/or bi-directional audio signals can be transmitted by insertion into both the beginnings and the endings of the active video line scan signals.
