Embodiment Construction

[0039]Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". The subsequent description of the specification is a preferred implementation mode for implementing the application, but the description is for the purpose of illustrating the general principle of the application, and is not intended to limit the scope of the application. The scope of protection of this application should be defined by the appended claims.

[0040] Such as figure 1 As shown, it is a multi-segmented medi...

Abstract

The invention discloses a multi-segment media file playing method. A media file comprises a first segment and a second segment connected with the first segment. The method comprises steps that, after downloading the first segment is accomplished, downloading of the first segment has nothing to do with subsequent de-multiplexing, decoding and rendering progress of the first segment, and the second segment is downloaded instantly; after de-multiplexing of the first segment is accomplished, de-multiplexing of the first segment has nothing to do with subsequent decoding and rendering of the first segment, head information parsing for the second segment is carried out instantly, after head information parsing for the second segment is accomplished, when decoding and rendering of the first segment is not finished, audio and video packet de-multiplexing for the second segment is carried out, corresponding decoding and rendering for the de-multiplexed data packet are carried out; splicing processing on a time stamp at the connection portion of the first segment and the second segment is carried out, and audio and video synchronization at the connection portion of the first segment and the second segment is accomplished. The invention further discloses a corresponding system. Through the method and the system, pause time between segment playing points is eliminated, and thereby playing smoothness is guaranteed.

Description

technical field [0001] The present invention relates to a method and system for playing media files, in particular to a method and system for playing multi-segment media files. Background technique [0002] The mobile streaming media service based on the open Internet is one of the best solutions to meet the needs of many applications such as live broadcast, on-demand and time-shifting in the future. Based on the audio and video services of the open Internet, the terminals can be TVs, computers, set-top boxes, PADs, smart phones, etc. It means providing services on the network, emphasizing the independence of services from physical networks. For the media content provided by major audio and video websites, most of the media content is stored and transmitted by dividing time into multiple segments (for example: a 90-minute movie can be divided into 9 segments, 10 minutes each), where each segment is a separate, complete media file that is identical in encoding. [0003] Cu...
