Starting delaying method for streaming media live broadcasting system

Abstract

The invention provides a starting delaying algorithm for a streaming media live broadcasting system, relates to the field of the streaming media live broadcasting on internet, and aims to solve the starting delaying problem of a client of an internet streaming media live broadcasting system. Following the development of an internet multimedia technique, an internet streaming media technique is more and more widely applied, but the advantages of the streaming media technique cannot be completely utilized because of the limitation on present network bandwidth and speed. The invention provides three dynamic starting delaying strategies, namely, a dynamic starting delaying strategy for gapping a density according to the broadcasting, a dynamic starting delaying strategy according to a network condition and a mixed type dynamic starting delaying strategy. According to a test result, the working effects and performance comparison of the three starting delaying strategies applied to the streaming media live broadcasting system are observed. According to the invention, the dynamic starting delaying strategies are combined with the streaming media technique, thereby achieving the purposes of reducing the frequency of interrupting the broadcasting at a terminal, ensuring the smooth broadcasting and protecting the sensory experience of a user.

Description

technical field [0001] The invention mainly relates to an Internet streaming media live broadcast system, and mainly considers the start-up time delay problem of the Internet streaming media live broadcast system client. Background technique [0002] This topic is supported by the Ministry of Education's New Century Excellent Talents Support Program (Project No. NCET-09-0709), the National Natural Science Foundation of China (Project No. 60970127) and the Ministry of Education's Science and Technology Research Key Project (Project No. 109029) . [0003] In the 21st century, the Internet has become one of the main media for people to obtain information. Due to the lack of network architecture and key technologies, as well as the immaturity of multimedia content processing technology, most of the early Internet could only transmit static information such as text and pictures. With the improvement of personal computer performance, the development of multimedia technology and t...

AI Technical Summary

Problems solved by technology

High-quality streaming media applications require a small packet loss rate to minimize the number of streaming media playback interruptions and protect the user's sensory experience. However, streaming media as a terminal application technology cannot reduce the network packet loss rate. , so that poor network conditions and other factors will cause frequent interruptions during the playback of the terminal

At present, the mature streaming media live broadcast systems on the market often use the traditional start-up delay strategy, which is often difficult to satisfy the real-time content and time synchronization of the live video broadcast system

The traditional streaming media startup delay strategy is to reach a fixed number of data packets in the buffer area or buffer for a fixed time and then start playing. In this way, when the network condition is good, the user's psychological demand for playing as soon as possible cannot be met. When the network condition is poor, will cause frequent interruptions
