This article focuses on the compressed representations of pictures. The representation does
not affect how many bits get from the Web server to the laptop, but it determines the …

Sulfated zirconia with S content of 2 wt.% equivalent to complete coverage of its surface was
studied by infrared spectroscopy. At least four sulfated species were identified and exhibited …

The objective of multiple description coding (MDC) is to encode a source into multiple
bitstreams supporting multiple quality levels of decoding. In this paper, we only consider the …

Video communication over lossy packet networks such as the Internet is hampered by
limited bandwidth and packet loss. This paper presents a system for providing reliable video …

We propose a system that improves the performance of streaming media CDN by exploiting
the path diversity provided by existing CDN infrastructure. Path diversity is provided by the …

Enabling video transport over ad hoc networks is more challenging than over other wireless
networks. The wireless links in an ad hoc network are highly error prone and can go down …

Video has been an important media for communications and entertainment for many
decades. Initially video was captured and transmitted in analog form. The advent of digital …

We describe the design, implementation, and evaluation of Popcorn, a media delivery
system that hides clients' consumption (even from the content distributor). Popcorn relies on …

In this paper, we examine the performance of specific implementations of multiple
description coding and of layered coding for video streaming over error-prone packet …

A new approach for multiple description video coding is proposed. It employs a second-
order predictor for motion-compensation, which predicts a current frame from two previously …
