We are concerned about the problem of transmitting constant quality video over the B-ISDN. A gain in channel utilization is achieved when several Variable Bit Rate video sources share a common ATM connection. To achieve such gain, the impact of cell losses on video quality degradation should be considered. Multi-layered video coding has proved to tolerate more cell losses than non-layered video...

Distributed Video Coding (DVC) is a video coding paradigm which mainly exploits the source statistics at the decoder based on the availability of side information at the decoder. This paper considers feedback channel based Transform Domain Wyner-Ziv (TDWZ) DVC. The coding efficiency of TDWZ video coding does not match that of conventional video coding yet, mainly due to the quality of side info...

Distributed video coding is a new video coding paradigm aimed at shifting the computational expensive motion estimation to the decoder. Side information is generated at the decoder as a prediction of the current frame. This creates a virtual dependency channel between the source video at the encoder and the side information at the decoder. Error correcting channel codes are used to correct the ...

The ITU-T draft H.26L video coding standard has been designed with the goal of enabling significantly improved compression performance relative to all existing video coding standards, as well as other important features, such as error resilience and network adaptability. While the basic coding framework of the standard is similar to that of currently popular video standards, H.26L includes many...

Super resolution technique was first proposed for enhancing the image resolution, and then it was expanded to video sequence for obtaining a higher resolution video from low resolution input. Recently, super-resolution based video coding has emerged as an important research topic as the image resolution increases rapidly and the downsampling coding is very efficient for bit rate reduction. With...

The emerging H.264 video coding standard offers a flexible coding algorithm for use in a range of applications from broadcast TV to low bitrate mobile applications. The flexibility comes with complexity. The H.264 video coding algorithm is complex and requires substantial amount of resources for encoding and decoding. The resources required to decode an H.264 video varies depending upon the enc...

The transmission of audiovisual media is one of the major tasks of communications engineering. Broadcasting (television and radio) is a typical application scenario. In modern digital transmission systems conventional video coding methods are used. Those coding methods are very suitable for the broadcasting scenario, due to their low decoding complexity. New application scenarios such as video ...

Aerial surveillance from Unmanned Aerial Vehicles (UAVs), i. e. with moving cameras, is of growing interest for police as well as disaster area monitoring. For more detailed ground images the camera resolutions are steadily increasing. Simultaneously the amount of video data to transmit is increasing significantly, too. To reduce the amount of data, Region of Interest (ROI) coding systems were ...

In the near future, certain 2D (2 Dimensional) video application scenarios are likely be replaced by 3D (3 Dimensional) video, in order to achieve a more involving and immersive representation of visual information, and to provide more natural methods of communication. Stereoscopic video is the simplest form of 3D video, which renders two slightly different views of a scene to perceive the dept...
