GB/T 17953-2012Interface for 4: 2: 2 digital component video signals in standard definition television (English PDF)

Foreword

This standard rule according to GB/T 1.1-2009 given draft.

This standard replaces GB/T 17953-2000 "4.2.2 digital component video signal interface", compared with the GB/T 17953-2000 the main changes are as follows.

--- Subject to the original standard was revised, clearly define the scope of this standard;

--- The original standard format has been revised and adjusted;

--- Original standard 4.1 adds illustration;

--- Original Standard 4.2.4 "Each timing reference signal generated by the four-word, the order FF0000XY" to "each timing group the reference signal from the four-word, order 3FF000000XYZ ";

--- The bit serial interface electrical characteristics of the rise and fall times of the allowable range from the "0.75ns to 1.50ns" to "0.40ns to 1.50ns ";

--- 6.6.2.4 delete the original standard input jitter;

--- Increase in the content of 5.7 cable interface features;

--- Delete the original criteria in Appendix A.

This standard uses redrafted law revision adopted ITU-RBT.656-5.2007 "in ITU-RBT.601 in 4.2.2 mode Digital 525 line and 625-line television under the system of component video signal interface "in the section on 625-line television systems, and the bit serial Rise and fall times of the allowable range of electrical characteristics of the interface by "0.75ns to 1.50ns" to "0.40ns to 1.50ns".

This standard was proposed by the State Administration of Radio, Film and Television.

This standard by the National Film and Television Broadcasting Standardization Technical Committee (SAC/TC239) centralized.

This standard was drafted. the State Administration of Radio, Film Radio and Television Planning Institute.
