Digital video technology has been characterised by continued growth in the last decade. The uses of video coding are broad and diverse. However, generally they fall into two main categories either utilising limited storage or transmission bandwidth. Video coding is essential for
Improved Transform Methods for Low Complexity , High Quality Video Coding
A video signal requires a very large number of bits if it is represented in an uncompressed form. This makes many video applications not possible, due to the limited bandwidth of communication channels and the limit of the storage medium. Therefore, video coders that compress the
Non-Predictive Multistage Lattice Vector Quantization Video Coding
In recent years, the demand for mobile multimedia applications has increased tremendously. Since the volume of the application data such as video is high and the bandwidth of mobile channels is limited, efficient compression techniques are very much required (Ghanbari, 2003) (Sik
Scalable Video Coding Using Wyner-ziv Codes
This papers proposes a solution to the problem of scalable predictive coding of video by posing it as a variant of the Wyner-Ziv side information problem. We model the predictor for each frame of a video sequence as being generated by passing the video frame through a hypothetica
Video Coding in H.26L
For the past few years, the capacity of global networks and communication channels has increased considerably. This allows for real-time applications like video conferencing and video-on-demand using compressed video. State-of-the-art video coding solutions such as H.263, MPEG-2
Scalable Video Coding
With the rapid improvements in digital communication technologies, distributing high-definition visual information has become more widespread. However, the available technologies were not sufficient to support the rising demand for high-definition video. This situation is further

The successful development of video-based services and applications in mobile environments requires adopting integrative approaches that jointly address video signal processing and networking issues. Multimedia data characteristics, coding standards and functionalities, as well a
Architectures of Incorporating Mpeg-4 Avc into Three-dimensional Wavelet Video Coding
3D wavelet video coding provides an elegant fulldimensional solution for scalable video coding. However, due to the Motion-Compensated Temporal Filtering (MCTF) with open-loop structure and no good rate distortion optimization trade-off between the texture coding and overhead cod
Overview of Framework for Spatially Scalable Video Coding
With the introduction of the H.264/AVC video coding standard, significant improvements have recently been demonstrated in video compression capability. The Joint Video Team of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG) has now
Special Section on the Joint Call for Proposals on High Efficiency Video Coding (HEVC) Standardization
Special Section on the Joint Call for Proposals on High Efficiency Video Coding (HEVC) Standardization THE FIRST commercially successful digital video compression standard emerged 20 years ago in the form of Recommendation ITU-T H.261. MPEG-1 and H.262/MPEG2 video (the latter was
