Some results of International Telecommunication Union-Telecommunication Sector (ITU-T) test model TMN1

摘要

Abstract: Recently, ITU-T established a test model (TMN1) to be used as a possible standard for very low bit rate video coding at less than 64 kbits per second. It is based on the ITU-T H.261 standard for videoconferencing. This paper provides an analysis of the performance of TMN1 coder with the aim of establishing its operational parameters and limitations when operating at very low bit rates. Its performance is then optimized by selecting the desired set of operational parameters.!5
