Description

实现实时视频信息共享的系统及方法技术领域本发明涉及在网络上实时传输视频信息的技术,特别涉及实现实时视频信息共享的系统及方法。 Real-time video information sharing system and method Technical Field The present invention relates to technology in real-time transmission of video information on a network, and particularly relates to a system and method to realize real-time video information sharing. 背景技术目前,作为第四媒体的网络正在带给人们的是各种各样的信息,不再只是单纯文本、图像和简单的声音文件,而是包含音、视频的多媒体技术,包括广播电视、新闻剪辑电台、电影、监控视频等。 BACKGROUND Currently, as the fourth media network is to bring people of all kinds of information is no longer just a simple text, images, sound files and simple, but includes multimedia audio and video, including broadcast television, radio news clips, movies, video monitors and so on. 想要使用这些多媒体信息, 就必须实现视频、音频信息在网络上的传输,但随着上网人数的趋增,而网络硬件设备的本身局限性,使得媒体文件的大小成为网络传输一个不可忽视的参数。 Want to use these multimedia information, it is necessary to implement video and audio information is transmitted on the network, but with the trend of increasing number of Internet users, and the limitations of their own network hardware, making the size of the media file to be a network transmission can not be ignored parameter. 一方面,人们希望能在网络上看到生动清晰、活泼精彩的媒体演示, 另一方面人们又不得不去面对媒体文件传输所需的大量时间。 On the one hand, people want to see clear and vivid, lively and exciting media presentation on the Web, on the other hand it has had to face a lot of the time required to transfer media files. 为了解决这种矛盾, 一种新的媒体技术应运而生,这就是流媒体(Stream Media)技术,流媒体又叫流式媒体。 In order to resolve this contradiction, a new media technologies have emerged, which is the streaming media (Stream Media) technology, also known as streaming media streaming media. 所谓流媒体是指采用流式传输的方式在IP网络中播放的媒体格式,如音频、视频或多媒体文件。 The so-called streaming media refers to streaming using the multimedia presentation in the IP network media formats, such as audio, video or multimedia files. 流媒体在播放前并不下载整个文件,只将开始部分内容存入内存,在计算机或手机中对数据包进行緩存并使媒体数据正确的输出。 Streaming media player does not download the entire file before, only the beginning of the content stored in the memory, the data packet is cached in a computer or mobile phone and media data correct output. 流媒体的数据流随时传送随时播放,只是在开始时有一些延迟。 Streaming media data streams transmitted at any time ready to play, but there are some delays in the beginning. 流媒体实现的关键技术就是流式传输,流式传输主要指将整个音频和枧频等多媒体文件经过特定的压缩方式解析成一个个压缩包,由流媒体服务器向用户计算机顺序传送。 The key technology of streaming media streaming is implemented, streaming audio, and mainly refers to the entire frequency soap multimedia file parsed into a compressed packet transmitted from the streaming server to the user computer through a particular order of compression. 在采用流式传输方式的系统中,用户不必像采用下栽方式那样等到整个算机上利用硬件或软件解压设备对压缩的音频和视频等多媒体文件解压后进行播放和观看。 In the system using streaming mode, the user does not like the above embodiment uses tilted downward and crashed on until the entire computer hardware or software decompression apparatus for compressed video and audio codecs and other multimedia files for playback and viewing. 此时多媒体文件的剩余部分将在后台继续下载。 At this point the remaining part of the multimedia files will continue to download in the background. 与单纯的下载方式相比,这种对多媒体文件边下栽边播放的流式传输方式不仅使启动延时大幅度地缩短,而且对系统緩存容量的需求也大大降低, 极大减少用户的等待时间。 Compared with the simple way to download, this way of streaming multimedia files while playing side tilted downward and crashed not only the start-up delay greatly shortened, and the demand for system cache capacity is also greatly reduced, greatly reducing user wait time. 采用流媒体技术可以实现视频信息的实时传输,目前主要用于视频监控系统,参见图1,图1为现有技术视频监控系统结构示意图。 Streaming media technology can achieve real-time transmission of video information, mainly for video surveillance systems, see FIG. 1, FIG. 1 is a schematic prior art video surveillance system architecture. 其中,流媒体服务器102连接了多个摄像装置101,通过摄像装置获得视频信息,生成实时视频流媒体数据。 Wherein the streaming server 102 connected to a plurality of image pickup device 101, the video information obtained by the imaging device, generating a real-time video streaming data. 流媒体服务器102可以由计算机来实现,其可以通过非对称数字用户线(Asymmetrical Digital Subscriber Line, ADSL ) 103等方式接入因特网110,远程监视终端105根据流媒体服务器102的地址,经因特网IIO访问流媒体服务器102实时获取视频信息,实现视频监控。 Streaming server 102 may be implemented by a computer 103, etc. can access the Internet 110 through an asymmetric digital subscriber line (Asymmetrical Digital Subscriber Line, ADSL), 105 address of the remote monitoring terminal according to the streaming media server 102, via the Internet accessible IIO streaming media server 102 to obtain real-time video information for video monitoring. 虽然视频监控已经广泛应用,但是目前各种实时视频资源基本都是不开放的,封闭的,当然这也是由于目前视频监控系统主要是应用于安全和私有场所,不允许其公开决定的。 Although video surveillance has been widely used, but there is a variety of real-time video resources are basically not open, closed, of course, this is due to the current video surveillance system is mainly used in safe and private place, do not allow the disclosure of the decision. 但随着网络娱乐化生活化的趋势,实时视频将不仅仅主要用于安防监控,而且还可以满足人们的娱乐生活需求,如商店超市、公园景点,甚至是个人都可以将安置的摄像头共享出来,而任何人都可以通过网络观看到各地共享摄像头传送的实时视频,如此将足够多的各种实时视频资源共享集中在一起,就可以实现用户足不出户即可看到任何有共享摄像头的地点的实时视频了。 But with the life of the network entertainment trend, real-time video surveillance will not only mainly used for security, but also to meet the people's entertainment needs, shops supermarkets, park attractions, and even individuals can be placed out of camera share , and anyone can watch real-time video sharing over the network to transfer the camera around, so enough of the various real-time video sharing resources together, we can achieve the user can see any homes have shared camera real-time video of the site. 但现在还没有提供一种统一开放的系统和方法集中共享各种可用的实时视频资源,来实现以上的新需求。 But still it does not provide a unified and open system and method
