摘要： A method, an equipment and a system for reducing a media delay are disclosed. A media processing unit receives a media switching request sent from a media receiving unit, and sends a response message and a media stream of a second media service to the media receiving unit according to the media switching request, where the response message includes information for the media receiving unit to reduce the media delay, so that the media receiving unit performs a media quickening process on the media stream of the second media service according to the received message including the information for reducing the media delay. An equipment and a system for reducing a media delay are also provided, which increase the switching efficiency of the media streams, reduce the difference of the display delay among different user media, and improve the degree of user experience.

摘要： Embodiments of the present invention provide a method, an apparatus, and a system for evaluating video quality. In the embodiments of the present invention, a method in the prior art that the video quality is determined only according to the number of lost packets and a packet loss rate is modified, and the location of the most important lost packet is determined by analyzing the influence of the lost packet on other packets, and a damage degree or degree of intactness of the video frame is determined according to the most important lost packets, so as to determine the quality of the video frame. The method greatly improves the precision for evaluating the video quality.
摘要翻译：本发明的实施例提供了一种用于评估视频质量的方法，装置和系统。在本发明的实施例中，现有技术中仅根据丢包数和分组丢失率确定视频质量的方法被修改，并且最重要丢失分组的位置是通过分析丢失分组对其他分组的影响，根据最重要的丢失分组确定视频帧的损坏程度或完整度，以确定视频帧的质量。该方法大大提高了视频质量评估的精度。

摘要： A method, a network node, and a system for suppressing lost packet retransmission are provided. The method includes: generating retransmission suppression information, in which the retransmission suppression information includes identification information of data packets requiring retransmission suppression; and transmitting the retransmission suppression information to a receiving node, in which the retransmission suppression information is used to enable the receiving node not to request retransmission when data packets corresponding to the identification information in the retransmission suppression information are lost after the receiving node receives the retransmission suppression information. The network node includes a generating module and a transmitting module. The system includes an intermediate node and a receiving node.
