TL;DR: This paper presents a cross-layer mapping architecture for video transmission in wireless networks and describes the design and algorithms for each building block, which either builds upon or extend the state-of-the-art algorithms that were developed without much considerations of other layers.

TL;DR: This paper uses computer simulation to explore the behavior of the probabilistic caching scheme when it works with various cache replacement policies and shows the different behavioral characteristics of the Probabilistic cached scheme as a function of the cache replacement policy.

TL;DR: In this article, a system and method for correcting artifacts present in video frames is disclosed, which includes a decision module (110) and an artifact correction unit (120), which receives artifact metrics (112) and artifact maps (122) corresponding to artifacts and prioritizes the video frames to be corrected by considering the type and severity of the artifacts and the content of video frames.

TL;DR: In this paper, a method and system for identifying and determining banding artifacts in digital video content composed of a sequence of moving video pictures is presented, which includes creating a mask image corresponding to a picture from a moving video picture based on global gradient changes to detect potential areas containing bands.

TL;DR: An adaptive protection scheme based on joint source-channel criteria is investigated via proactive forward error correction (FEC) in Reed Solomon (RS)/rate-compatible punctured convolutional (RCPC) codes to match the relative priority of source packets and instantaneous channel conditions.
