Comparison of Video Compression Standards

VIDEO COMPRESSION: The MPEG Standards

In order to ensure compatibility among video codecs from different manufacturers and applications and to simplify the development of new applications, intensive efforts have been undertaken in recent years to define digital video standards. These standards were the result of joint development efforts of video and audio compression as well as other system aspects required to support all the appl...

Digital Video Compression Fundamentals and Standards

Over the past decades, digital video compression technologies have become an integral part of the way we create, communicate and consume visual information. Digital video communication can be found today in many application sceneries such as broadcast services over satellite and terrestrial channels, digital video storage, wires and wireless conversational services and etc. The data quantity is...

Comparison of the H.263 and H.261 Video Compression Standards

The draft international standard ITU-T H.263 is closely related to the well known and widely used ITU-T Recommendation H.261. However, H.263 does provide the same subjective image quality at less than half the bit-rate. In this paper we investigate to what extend single enhancements of H.263 contribute to this performance gain, and consider the trade-oo quality vs. complexity. Based on the test...

Numerical Approaches on Coding Efficiency for Video Compression Standards

In this paper, we present some numerical techniques and approaches that can improve compression efficiency and enhance performance for video coding standards. The primary objective in this paper is to describe the analysis process when an approximation error is encountered during the process of replacing integer division by multiplication and bit shifting. In addition we present a method that o...
