Status Report on Video Standards; IEEE Video Signal Transmission Subcommittee 2.1.4

The Video Signal Transmission Subcommittee 2.1.4 of the IEEE Group on Broadcasting is actively engaged in preparation of standards dealing primarily with the transmission and monitoring of baseband video signals. Subjects now under discussion are 1) methods of measurement of linear waveform distortion including the use of sine-squared techniques; 2) definition and measurement of dynamic gain; and 3) measurement of impedance errors using the return loss principle. The present status of this activity is reviewed and similar work done by other organizations such as the CCIR and EIA is surveyed.
