The meeting proposed that from 2010 to 2012, we will focus on the two-way entry of radio and television and telecommunications services, and clarify the scope of telecommunications entering the broadcasting industry. This means that telecom companies will not only serve as transmission channels for broadcast and television programs, but how to integrate external information resources and even independently to do information content and speed up control of scarce content resources is the key to improving their competitiveness.

 Because the three networks each have many problems such as limited capacity resources, low transfer efficiency, and technical over-personification, they are not suitable for the development of modern information society. Therefore, the characteristics of the Internet Protocol Television (IPTV) system and its advantages in the video field make it the "three-network convergence," the biggest entry point. For the telecommunications industry, the IPTV value-added approach to video-based services has become the major telecommunications Operators are seeking a choice for sustainable development. Internet services are scarce and profitable. Therefore, leveraging the advantages of telecom's own broadband network, the development of IPTV services has become the original driving force for industry transformation.

Unicast programs include unicast live broadcast, on-demand, look back, time shift, and other media services carried in unicast mode.

 The discovery of a unicast program failure may be caused by an end user reporting, that is, a user reporting a fault or an operation and maintenance personnel discovering that the user's corresponding experience indicator is abnormal through the monitoring system.

 When the user's unicast program plays abnormally, the basic information of the faulty program can be determined. The faulty program basic information includes: the faulty program name, the faulty user account, the related STB device information, the faulty program name viewed by the user, and the fault occurrence time. , fault duration, etc. The media information of the media station to which the faulty program belongs and the media file of the faulty program on the media server can be determined by the faulty program basic information.

The device connected to the network device is faulty.

 Step 202: If it is determined that the line or device between the third-level access device and the user is faulty, determine that the same user or the other user that belongs to the second-level access device receives the same or approximate bandwidth in the same period. Whether the service quality data of the program is abnormal, if abnormal, it is determined that the second-level access device is faulty or the line between the second-level access device and the third-level access device is faulty, and if it is normal, the second-level access is determined. There is a fault in the line or device between the device and the user.

Whether the quality of service data of the program of the approximate bandwidth is abnormal, and if abnormal, determining that the N-1th access device is faulty or between the N-1th access device and the Nth access device There is a fault in the line; otherwise, it is determined that the line or device between the N-1th access device and the user is faulty;  Judging step by step until it is determined that there is a fault in the line or device between the first level access device and the user. 8. A system for fault locating an abnormal broadcast of a unicast program, comprising an export media indicator data determining module and a first fault determining module, wherein:  The egress media indicator data determining module is configured to: when an abnormality of the unicast program of the user occurs, determine an export media indicator data of the media server where the faulty program is located;  The first fault determining module is configured to: determine, according to the export media indicator data, whether the media server has a fault or whether a media file on the media server is faulty.  9. The system of claim 8 further comprising a media server information determining module, wherein: The media server information determining module is configured to: determine basic information of the faulty program, and determine, by the basic information, media server information where the faulty program is located and a media file of the faulty program on the media server. 10. The system according to claim 9, wherein the basic information comprises: a faulty program name, a faulty user account, related STB device information, a faulty program name viewed by the user, a fault occurrence time, and a fault duration.  The system according to any one of claims 8 to 10, wherein: the egress media indicator data determining module is configured to determine egress media index data of a media server where the faulty program is located in the following manner:  Playing the faulty program by using the media server as a source of play, and using another media server or test device in a normal state as a receiving end, receiving, by the receiving end, the faulty program, performing a play-batch test, and calculating the Describe export media indicator data.  12.
