ABSTRACT:
A method of generating an MPEG sequence for multiple component analog video measurements modifies a general purpose encoder and provides an MPEG encoded signal to test a device under test (DUT) component analog output that is valid in both RGB and YPbPr in both pulse and bar and that solves digital RGB cross-talk due to aliasing of Cb and Cr in 4:0:0 and 4:4:4 formats. The general purpose encoder is modified by removing vertical pre-filtering and post-filtering, altering quantization tables alternate scanning for vertical redundancy, and turning off motion estimation. The input to the MPEG encoder is pre-aliased to provide minimum digital cross-talk after MPEG compression by repeating every other sample.
