Embodiment Construction

[0058] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0059] Composition and working mechanism of synchronous playback control mechanism

[0060] Refer to figure 1 As shown, the streaming media synchronization playback control device includes a splitter, a decoder group, a multi-source streaming media synchronization module, a multi-source video stream fusion module, an OSD module, and an audio filter.

[0061] The separator is used to receive media data from multiple local media files or multiple streaming media on the Internet, and perform format identification and separation on them. There is a piece of data at the beginning of the media file that can be used to identify the media format. This part of the data includes the file type, the number of data streams contained, the data stream type, and the encoding algorithm of the data stream. According to this information, the media can be separated into separate vi...

Abstract

This invention discloses a synchronous play control method for supporting multi-source flow media, in which, a device realizing said method includes a separator, a decoder set, a multi-source flow media module, a multi-source video flow combination module, an OSD and an audio filter lens, in which, the separator separates the video and audio data in the multiple local media files or the multiple flow media, the decoder set calls related decoders to decode them to be sent to the multi-source flow media synchronous module, which applies a system of multi-size hierarchical synchronous control to control the multi-route media flow synchronously among and in the media objects, the multi-source video combination module combines multiple videos to one route, the OSD module laminates the combined data, volume, the current play time or caption information to output the video, the audio filter lens carries out formation transformation and linear overlap to the multiple audios then to output the audio.

Description

[0001] Field [0002] The invention belongs to the field of computer design and application technology, and relates to computer software, multimedia technology, and video and audio processing technology, and in particular to a synchronous playback control method that supports multi-source streaming media. Background technique [0003] The rapid development of multimedia technology has promoted the continuous improvement of people's demand for complex media presentation, and has gradually become the most effective means for people to obtain and transmit information and conduct networked independent learning. Therefore, each operating system has always strived to be able to achieve perfect support for multimedia. [0004] Multi-source streaming media is a complex media type that supports simultaneous playback of two or more streaming media data and performance in a specific manner (such as "picture-in-picture", multi-window). It has further improved the performance and information co...
