Compression Formats for HD Recording and Production Host Publication: High-Quality Visual Experience: creation, processing and interactivity of high-resolution and high-dimensional video signals Authors: J.

Abstract: As a result of the consumer's increasing demand for better quality and higher resolutions, the transit to television broadcasting in HD, with a resolution of at least 1280 x 720 pixels has recently started to take shape. In this respect, an important challenge is the selection of a suitable format for recording and production of HD material. One of the issues is that high definition, unlike standard definition, is quite an ambiguous term. In the first phase of HD television broadcasting deployment, two different formats were put forward: 720p50/59.94/60 or 1080i25/29.97/30. In the first part of this chapter, the benefits and drawbacks of both options will be discussed in detail. Besides the choice between 720p and 1080i, the selection of the video compression format and parameters for HD recording and production is also an important consideration. In this chapter, two state-of-the-art intra-only compression formats will be reviewed and compared: Motion JPEG 2000 and H.264/AVC Intra. First, an in-depth description of both video codecs will be provided. Thereafter, the compression schemes will be evaluated in terms of rate-distortion performance, recompression loss and functionality.
