Cost vs. Quality in ATV Receivers

ACATS and ATSC have proposed formats for advanced television which have cost and quality implications for various types of receivers. DemoGraFX has an alternative approach to advanced television, which optimizes a different class of receivers. — The cost and quality issues for each type of advanced television format, on each type of receiver, are explored and analyzed. — Issues which arise are motion analysis, de-interlacing, frame rate conversions, aspect ratio conversions, and colorimetry conversions. For ATV formats which have non-square pixel spacing (as proposed in ACATS SDTV formats), the pixel spacing adjustment is also needed. — Decoding performance, and associated computation, are also an issue. When decoded formats don't match display formats, decoder and encoder tradeoffs have implications in the conversion processing. — These and other issues in receiver quality and cost are examined.
