摘要

本文主要研究了多通道P2P直播系统的信道切换时延问题。在研究了多通道视频系统的基本方面，包括频道切换、同伴流失和频道受欢迎程度之后，我们借鉴用户行为定位的思想，开发了一种新的面向用户行为和面向内容的预缓冲机制，以改善直播中的用户体验。这种新机制利用用户行为记录对用户的观看行为进行预测。该方法可获得平均约40%的预缓冲成功率，并使信道切换延迟大大降低。

A Pre-buffer Mechanism in Multi-channel P2P Live Streaming

In this paper, we mainly concern about the channel switch delay of multi-channel P2P live streaming system. After study the essential aspects of multi-channel video systems, including channel switching, peer churn, and channel popularity, we develop a new user behavior oriented and content oriented pre-buffer mechanism to improve the user experience in live streaming borrowing the idea of user behavior targeting. This new mechanism uses the user behavior records to make a prediction of user's viewing. It can get a pre-buffer succeed ratio about 40% on average, and make the channel switch delay much lower.
