Color Video Quad Processors

The color video quad processor systems take analog video inputs from the video output based on the user preference. These color video quad processors allow the users to control the video output using the following display modes: quad split, full screen, PIP (picture in picture), dual screen (2 camera split), and auto sequence. Video quad processors are user-friendly and highly effective. They have smart automatic switches which allow random sequences and dwell time programming, single-screen playback zoom, and partial zoom screen.

Functions of Color Video Quad Processors

These color video quad processors use digital technology to process and store the video information received from the camera. These incoming video images are transformed into digital signals by an analog-to-digital (A/D) converters. This information is stored in memory and clocked out at a rate predetermined by the video processor. They have clocked rate which synchronizes the incoming video signals from the four cameras and enables them to be combined with a single video output in full screen or in quad format. As long as the camera signal contains the required sync signals to be displayed on a monitor, they can be mixed together with other camera inputs. After these digital signals are clocked out of memory, they are converted into an analog signal by digital-to-analog (D/A) converter and channeled to video outputs. Each signal clocked into memory is held, sampled and clocked out at a rate of one video frame every second. Once in memory, these video processors can display the video on a full screen, and in the quad, format zoomed to a quadrant playback mode.

Features

GAO Tek’s processors provide videos to DVRs, VCRs, and alarm inputs and outputs. They also provide high-quality split screen output for real-time multiple video channel displays, live monitoring, and recordings. Color video quad processors deliver high-resolution pictures with broadcast quality and have built-in date and time stamp generators. Video quad processors often use video standard PAL & NTSC and their video display modes such as sequence switch, single picture, PiP zoom function, quad, and freezing. These color video quad processors work with dual-mode automatic switching PAL/NTSC standard, full-screen real-time display, and real-time refresh rate. Color video quad processors can do both video and real-time monitoring simultaneously. These devices usually have built-in OSD, clock and date generators, color off channel functions. They have alarm modes include video loss alarm, signal loss alarm, mobile alarm, video motion alarm, and external alarm with high and low alarm output modes. They also have a different level sensitivity of motion detection with automatic display of picture and alarm when motion detected. They have a selectable sequence switch, single-screen, auto switch (PiP), single video mode, three sub-window modes. The devices provide image zoom/freeze frame function and also can freeze all the windows simultaneously.

Applications and Industries

Color video quad processors are used for many applications such as video entertainment, multimedia applications, security surveillance, industrial monitoring, and video preview applications where multiple images are required in a limited space.
