This paper describes a new video coding scheme based on a simplified block structure that significantly outperforms the coding efficiency of the ISO/IEC 14496-10 ITU-T H.264 advanced video coding (AVC) standard. Its conceptual design is similar to a

In this paper, we consider a hybrid P2P video on-demand architecture that utilizes both the server and the peer resources for efficient transmission of popular videos. In our system architecture, each peer dedicates some cache space to store a partic

We consider the problem of predicting packet loss visibility in MPEG-2 video. We use two modeling approaches: CART and GLM. The former classifies each packet loss as visible or not; the latter predicts the probability that a packet loss is visible. F

Summary form only given. High-resolution color video (in 4:4:4 format) is becoming increasingly important for screen content and graphics. We have developed a frame packing arrangement (FPA) scheme that enables transmission of 4:4:4 luma-chroma (YUV

We present a method to convey high-resolution color (4:4:4) video content through a video coding system designed for chroma-sub sampled (4:2:0) operation. The method operates by packing the samples of a 4:4:4 frame into two frames that are then encod

In this paper, we propose a generalized linear model for video packet loss visibility that is applicable to different group-of-picture structures. We develop the model using three subjective experiment data sets that span various encoding standards (

Our work builds a general visibility model of video packets which is applicable to various types of GOP (Group of Pictures). The data used for analysis and building the model come from three subjective experiment sets with different encoding and deco

In this paper, we propose a method for peer assisted on demand delivery of scalable video using an optimal, distributed caching algorithm for cache constrained peers. We assume that there are one or more content delivery servers that are provisioned

The bulk of the video content available today over the Internet and over mobile networks suffers from many imperfections caused during acquisition and transmission. In the case of user-generated content, which is typically produced with inexpensive e

Multimedia services for mobile phones are becoming increasingly popular thanks to capabilities brought about by location awareness, customized programming, interactivity, and portability. With mounting attraction to these services there is desire to
