面向内容监管的P2P-TV音视频数据还原与在线检测方法研究
Research on audio/video data recovery and online detection method of P2P-TV for content monitoring
摘要
Abstract
For the purpose of online content monitoring on P2P-TV, this paper firstly made a short introduction to the monitoring system of P2P-TV. Then according to the fact that PPTV utilized ASF to transmit data and that peers obtained data from each other by UDP method, based on the accurate identification of platform and channel of P2P-TV, this paper identified the audio/video data packets in the process of data transmission, and then acquired the serial numbers of those packets, the length of audio/video data, the beginning and ending of audio/video data in each packet, finally extracted the audio/video data online , recovered them to media files and implemented content detection.关键词
