BS EN 62375 discusses video systems (625/50 progressive) and video and accompanied data using the vertical blanking interval with a focus on the analogue interface. BS EN 62375 specifies the method of transfer of aspect ratio information code, copy control information code, and other codes in the vertical blanking interval of the luminance signal.
BS EN 62375 is applicable to the transfer of video related information with the video signal through the baseband analogue signal of 625-line/50-frame progressive scan video system between digital and analogue video equipment.
BS EN 62375 on video and accompanied data is useful for:
Specifies the aspect ratio code and the copy control information code and the method of transfer of these codes in the vertical blanking interval of the luminance signal.
BS EN 62375 discusses defined signal, construction of identification signal, clock frequency, signal amplitude, modulation coding, preamble, data bits information content of data bits, rules of operation, and procedure in absence of identification signal. This will help you with the method of transfer of aspect ratio information code in the vertical blanking interval of the luminance signal.
