Server-directed transcoding

Architecture and pragmatics of server-directed transcoding

Proxy-based transcoding adapts Web content to be a better match for client capabilities (such as screen size and color depth) and last-hop bandwidths. Traditional transcoding breaks the end-to-end model of the Web, because the proxy does not know the semantics of the content. Server-directed transcoding preserves end-to-end semantics while supporting aggressive content transformations. We show ...

Server Directed Transcoding—a short overview

TranSquid : Transcoding and Caching Proxy for Heterogenous E-Commerce Environments

With the advent of the Wireless Internet, the client space has become heterogeneous in terms of device capabilities. To cater to the needs of these devices in E-Commerce applications, smart intermediaries have been developed to increase the user satisfaction by hiding the inherent weakness of some of the small although handy devices like the PDAs and Web-tops. Transcoding has been a popular tec...

Performance Bounds for P2P Streaming System with Transcoding

In this paper, we develop a fluid model that seeks to expose the fundamental characteristics and mathematical theory of peerto-peer streaming system with transcoding. We find out and prove that, to provide peers receiving data above some flow rate, there is a lower bound of server upload bandwidth in this kind of system. We give a flow rate allocation algorithm to achieve the minimal server upl...

Meta-caching and meta-transcoding for server-side service proxy

This paper proposes novel concepts of meta-caching and metatranscoding which indicate that intermediate results (metadata) of video transcoding sessions are cached and subsequent identical service requests are served through transcoding from the cached metadata. The proposed methods provide a foundation to achieve superior storage and computation resource balance at service proxies for heteroge...

Cooperative Architectures and Algorithms for Discovery and Transcoding of Multi-version Content

A clear trend of the Web is that a variety of new consumer devices with diverse computing powers, display capabilities, and wired/wireless network connections is gaining access to the Internet. Tailoring Web content to match the device characteristics requires functionalities for content transformation, namely transcoding, that are typically carried out by the content Web server or by an edge p...
