Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Terminal devices need to play streaming media smoothly. Due to the impact of bandwidth, cache, etc., an adaptive streaming media segment download method is needed to achieve this. Hereinafter, streaming media fragmentation is directly referred to as fragmentation for the convenience of description.

[0026] In the embodiment of this application, the terminal device can receive and store the code rate group level issued by the content service provider, and the code rate corresponding to each code rate group; it can also configure the code rate group level locally, and the code rate corresponding to each code rate group Rate.

[0027] If the code rate corresponding to each code rate group is a continuous code rate, it can a...

Abstract

The invention provides a streaming media fragmentation downloading method. The method includes the steps that when a terminal device determines that a current cache duration is less than a first threshold value and no fragmentation downloaded in process exists at present, the optimal code rate is decided through an MDP; in terms of grades, a code rate set where the optimal code rate exists is compared with a code rate set where a code rate at which a fragmentation is downloaded before; the code rate at which a next fragmentation is downloaded is determined according to the comparative result. Based on the same inventive concept, the invention further provides a streaming media fragmentation downloading device through which smooth broadcasting of streaming media can be achieved under a dynamic network environment.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a streaming media segment download method and device. Background technique [0002] Currently, when providing media content, network video operators not only need to consider all types of terminal equipment, but also need to adapt to the dynamic changes in capability and bandwidth of the same terminal equipment, so as to ensure smooth viewing experience for users. [0003] Faced with the challenges of terminal equipment capabilities and bandwidth changes, adaptive streaming media technology emerged as the times require. The working principle of adaptive streaming media technology is: firstly, the content is divided into multiple fragments according to multiple bit rates, and stored in On the server; then when the content is played, according to the network bandwidth and media processing capability of the terminal device, dynamically select a content file with a suitable bi...
