Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] As shown in Figure 3, the network streaming media player supporting multi-viewpoint video synthesis provided by the present invention is composed of a data receiving module 100, more than one decoding module 200, a synthesis module 300 and a presentation module 400, the solid line in the figure Arrows represent the direction of data flow, and dashed arrows represent the direction of control flow.

[0022] On the one hand, the data receiving module 100 receives compressed video code streams from multiple camera viewpoints from the streaming media server through more than one IP network connection, and on the other hand, it is connected to more than one decoding module 200, and forwards the received different viewpoints to the latter The compressed video frame data. In addition, the data receiving module 100 also receives a viewpoint switch comm...

Abstract

This invention relates to a network stream media player supporting the video composition of multiple viewpoints including a data receiving module and a showing module characterizing in also including more than one decoding modules and a composite module, in which, the data receiving module connects and receives compresed video code streams by more than one IP and transfers received data to the decoding modules, besides, it receives viewpoint switch instruction from UI and transfers it to the composite module, said decoding modules receive data of the compressed video frame and decode to transfer the decoded original video fame data to the composite module, which receives the original video frame data and combines them virtually then to transfer the result to the showing module and rceives viewpoint switch instruction from the data receiving module, and the showing module transfers the virtual video frame to a display device.

Description

technical field [0001] The invention relates to the technical field of multi-viewpoint video processing and network streaming media, in particular to a network streaming media player and method supporting multi-viewpoint video synthesis. Background technique [0002] Currently, network streaming media players based on personal computers have been widely used. As shown in Figure 1, the framework of the streaming media player of prior art is mainly made up of data receiving module, decoding module and presenting module, and the data flow between each module is through the output interface of sender module and receiver module A data path is established between the input interfaces to complete. In addition to the data path, there is no more coupling between modules, which can achieve better module packaging. The functions of each module are described in detail as follows: [0003] The data receiving module is mainly responsible for interacting with the streaming media server ...
