This standard specifies the minimum requirements for the specification and testing of the performance of a video transmission channel involving transmitter, receiver or intermediate devices associated with the selected transmission media, for use in CCTV surveillance systems.Video transmission equipment may be combined with additional functions, e.g. for audio or data transmission. These functions are not included in this standard.This standard covers the transmission of colour and black and white video signals in accordance with CCIR Report 624-4, 625 lines, 50 fields per second.This standard is not applicable for transmission systems which use in the whole system or in parts thereof compressed video signals in any way.NOTE Compression techniques use methods to match the information content of signals to the best channel capacity. The various test signals of this standard applied on different methods to compress video signals can supply results which meet the requirements of this standard. However, it should not be concluded from such results that those parts of transmission systems using methods to compress video signals are able to transmit a real video signal with a high information content in the correct way.Methods to compress video signals can use techniques reducing video signals without any loss of information (so called “redundant reduction”) or with some loss of information (so called “irrelevance reduction”).
