Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0030] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0031] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static rando...

Abstract

The invention aims at providing method and device for pre-acquiring live program information from CDN (Content Delivery Network). The method comprises the following steps: acquiring a second two-stage M3U8 file and a third two-stage M3U8 file corresponding to a live program, wherein the third two-stage M3U8 file is determined based on the second two-stage M3U8 file and the live delay information corresponding to the live program; acquiring the live program information from the live program, corresponding to the second two-stage M3U8 file and the third two-stage M3U8 file, so as to meet the subsequent related live requests. Compared with the prior art, the method has the advantages that the (delayed) live program information is pre-obtained through an one-stage M3U8 file and a two-stage M3U8 file, and thus, the bandwidth resource utilization rate can be raised, and the program access experience of a user can be improved; the pre-obtaining method can be used for effectively solving the problem of network jittering, in order to ensure the live program quality for a user.

Description

technical field [0001] The invention relates to the computer field, in particular to a technique for prefetching live program information in a CDN network. Background technique [0002] Prefetching is based on the fact that when content service providers and network operators build content delivery platforms (CDN, ContentDelivery Network), they integrate prefetch modules through CDN nodes that provide user services and prefetch the content in the source CDN nodes in advance in the way of returning to the source. program content. [0003] The existing IPTV live broadcast is transmitted through routing multicast, and the user service QoS guarantee is satisfied by the constraints on the broadband of the IPTV private network. Internet TV live broadcast is transmitted on the public network through unicast, and cannot satisfy its user service QoS guarantee by restricting the bandwidth of the public network. Among the two basic services of live broadcast and on-demand Internet TV...
