Abstract

The embodiment of the invention provides a multimedia data playing method and device. The multimedia data playing method comprises the following steps: a Flash plug-in and a multimedia device build adata stream channel; the Flash plug-in obtains program stream data from the multimedia device through the data stream channel; the Flash plug-in extracts multimedia data from the program stream data;and the Flash plug-in plays the multimedia data. According to the embodiment of the invention, because of the widespread popularity of Flash plug-ins, users generally do not need to download the Flashplug-ins when the PS stream is played, therefore, the process of downloading and installing are avoided, and the simplicity of the operation is greatly improved; the PS stream is not required to be converted into a video protocol or format supported by the Flash plug-in in the background, such as RTMP, therefore, the maintenance of a professional streaming media server and the secondary development of the backstage are avoided, and the cost is reduced; and the background conversion is not required, therefore, the delay of video is reduced.

Description

technical field [0001] The invention relates to the technical field of multimedia processing, in particular to a multimedia data playing method and a multimedia data playing device. Background technique [0002] In the digital TV system, the analog audio and video signals form an elementary stream (Elementary Stream, ES) after sampling, quantization and compression encoding according to the MPEG-2 (Moving Picture Experts Group) standard. Continuous stream of segments. Packetized Elementary Stream (PES) is formed by dividing the elementary code stream into segments and adding corresponding header files. The PES packets may be discontinuous between the PES packets. [0003] During transmission, the PES packets are segmented into fixed-length transport streams (Transport Stream, TS) or variable-level program streams (Program Stream). [0004] Since the length of the PS packet changes, once the synchronization information of a certain PS packet is lost, the receiver cannot det...
