We present a novel technique for efficient coding of texture to be mapped on 3D landscapes. It enables the streaming of texture information across bi-directional networks like the Internet. The algorithm can be used with many transform based coding schemes ...
We show a rate-distortion optimal way to threshold or drop the DCT coefficients of the JPEG and MPEG compression standards. Our optimal algorithm uses a fast dynamic programming recursive structure. The primary advantage of our approach lies in its complet ...
MPEG is traditionally committed to the coding and compression of audio-visual data from natural sources. However, the emerging MPEG-4 standard aims not only at encoding the multiple natural audio-visual objects composing the scene, but also synthetic audio ...
This paper investigates the performance of AAL5 under cell loss conditions for real-time MPEG-2 based video applications. The figures derived through simulations show poor performance due to AAL5 limited error correction methods. The results motivate the i ...
In this paper, we present a new rate control mechanism for delay sensitive MPEG-2 video services over ATM networks. The rate control constraints the video bitstream to respect the three negotiated VBR ATM traffic contract parameters modelled by a dual leak ...
In this paper we study the perceptual impact of data loss on MPEG-2 video coded streams transmitted over an ATM network. This impact is measured using a perceptual quality metric based on a spatio-temporal model of the human visual system. Video streams ha ...
A stable clock indication is needed for the processing and playout of MPEG-2 streams. ATM networks can support the transfer of such streams but contribute significantly (as well as other system operations) to delay and delay variation. The MPEG-2 standard ...
