Paper Abstract

The different nature of the TV and HDTV signals, which hold dissimilar features from both the statistical and perceptual points of view, implies that the same behavior cannot be expected from the encoding procedure. Here, it is shown a comparison of the performances of a Hybrid DCT bit rate compression system when applied to information of each type. This study is carried out taking as a basis the statistics of the output data which result from the processing of corresponding HDTV and TV sequences, and it is described by several sets of data, relevant at different stages of the encoding process, such as DCT-domain energy distributions, quality versus bit rate curves, and final symbol statistics.
