Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] First, taking the DASH video transmission protocol as an example, the player on the terminal device plays the live content as follows:

[0027] refer to figure 1 As shown, referring to the clock axis, if the current time is T1, the content of the live video is the content A starting at time point T1. Such as figure 1 As shown, after content A is processed, live data will be generated and stored synchronously on the server. Due to the limited space al...

Abstract

Embodiments of the invention disclose a data playing method and terminal equipment, and relates to the field of audio and video processing, and are used for avoiding from increasing the delay betweenplaying data played on the terminal equipment and live broadcast data stored by a server in order to reduce or avoid the occurrence of a live broadcast failure condition. The method comprises the following steps that the terminal equipment loads the live broadcast data sent by the server in a cache; the terminal equipment reads the current playing data in the cache and plays the current playing data; the terminal equipment determines the delay between the current playing data and the live broadcast data according to the current live broadcast time of the live broadcast data and the playing time of the current playing data; and the terminal equipment adjusts the playing speed of the current playing data according to the delay.

Description

technical field [0001] Embodiments of the present invention relate to the field of audio and video processing, and in particular, to a data playing method and terminal equipment. Background technique [0002] DASH (Dynamic Adaptive Streaming over HTTP, dynamic adaptive streaming based on HTTP) video transmission protocol is a protocol based on the Internet to transmit video, which can dynamically adapt to changes in network bandwidth. According to the size of the bandwidth, the player can choose different bandwidth video data for playback. The DASH protocol can transmit VOD (Video on Demand) video programs of the on-demand type, and can also transmit live video programs of the Live (Live) type. [0003] Due to the characteristics of live video, the live data of live video is generated and stored in the server in real time, and when the live data is generated for a period of time (usually one minute to tens of minutes), and due to the limited server space, the live data will...
