The RCA Interface (CVBS)


Composite Video Broadcast Signal


CVBS is short for Composite Video Broadcast Signal. This is the most common video interface, the first application in the field of radio and television, then a lot of camera output support the CVBS interface, CVBS signals are interlaced video signal, and a resolution of 720 x576 (PAL) or 720 x480 (NTSC), CVBS is the analog video signal interface, has gradually been digital video signal interface and replace the hd video signal interface.


The AV interface (CVBS)


AV video interface English full name is: "Composite video connector", AV terminal is usually consists of three lines, transmission of video is usually yellow RCA terminal, the other with two red and white RCA terminal transmit audio, transmitted in AV terminal is analog TV signal source of three elements: Y, U, V, as well as the benchmark of the pulse signal synchronization. Y represents the brightness of the image (luminance, also called brightness), and contains the sync pulse, as long as there is signal Y can see black and white television image (in fact, this is the method of color TV and early black and white TV compatible). The U and V signals are loaded with color data. The U and V are first mixed into two sets of orthogonal phases ina signal (the mixed signal is called Chrominance), and then summed with the Y signal. Since Y is the fundamental signal and UV is mixed with the carrier, this summing action is equivalent to frequency division multiplexing.
