Transmission control method and player of online streaming media

Abstract

The invention relates to a transmission control method of online streaming media, comprising the following steps: checking whether data after a current playing point of a streaming media file cached in a local buffer area fully occupy a non-speed-limit downloading area or not, downloading the streaming media file from a network side through a CDN (content distribution network) low-speed downloading mode and playing the streaming media file if the data fully occupy the non-speed-limit downloading area; or continuously downloading the streaming media file from the network side via a CDN non-speed-limit downloading mode. The non-speed-limit downloading area is a data storage area between a starting storage position and a preset non-speed-limit downloading critical line, and the low-speed downloading mode is a downloading mode with a downloading speed not higher than a code rate of the streaming media file. The invention further relates to a player of the online streaming media. The transmission control method and the player of the online streaming media can switch a transmission speed and a transmission mode according to the streaming media data receiving situation of a terminal and save the consumption of system resources and network bandwidths at a terminal side and a server side on the premise of ensuring smooth transmission and play of the streaming media file.

Description

technical field [0001] The invention relates to streaming media technology, in particular to an online streaming media transmission control method and player. Background technique [0002] In the current Internet, two mainstream implementation technologies for online streaming media transmission are peer-to-peer (Peer to Peer, P2P for short) technology and content delivery network (Content Delivery Network, CDN for short) technology. [0003] The core of CDN is to push the content of the central server to the edge nodes of the network, so that users can obtain services nearby, thereby ensuring the quality of service (Quality Of Service, referred to as QoS) and service availability. Network pressure, in essence, CDN is an improved server / client (Client / Server) technology, which has the basic characteristics of Client / Server in performance: reliable service capability, high service quality assurance, but the system The expansion of service capabilities needs to be based on th...

However, each Peer can terminate the service or even exit at any time, and the exchanged content may be deleted or terminated at any time.

In addition, when P2P technology is applied on other terminals with lower hardware configuration and weaker performance, such as set-top boxes, mobile phones, and embedded operating system terminals, establishing P2P connections with multiple peers will consume a lot of terminal resources

[0005] For both CDN and P2P technologies, there is also a problem that during the download process of online streaming media data, if the terminal is always in the full-speed download state, it will affect other service processes running on the terminal.
