【摘要】：对家庭终端用户来说,大资源、大数据的传输受到技术约束,从根本上制约了互联网点播的应用,限制了实时在线点播技术的推广。但随着21世纪互联网宽带速度的不断提高,在线数据传输及在线视频点播技术的使用更加广泛,其相关产业迎来了新的发展机遇;流媒体资源在线播放技术正被普遍应用到包括互联网媒体、网络课程、员工培训、娱乐、广告等的各行各业中。终端用户的网络带宽已不在制约大数据的传输及视频资源的在线播放,新的网络媒体传输技术的出现及推广,已从根本上解决了在线点播的流畅度问题。本课题主要研究在线视频点播系统,在简要介绍相关技术,分析流媒体资源特点、技术应用及发展前景的基础上,讨论并研究了石化城影院播放系统的设计与开发。系统将资源文件压缩、发送,客户端完成数据接受播放是实现石化城影院播放系统的关键,而上述技术则能有效保证数据包在网络间的快速传输,提高用户体验。在完成以上技术理论研究的基础上,本文提出了以Windows平台为载体,采用先进的流媒体技术,数据传输及通用的播出协议的设计方案。在多次征求员工意见,分析需求偏好的基础上,设计性能优越、扩展灵活系统架构,并开发性能可靠、结构合理、功能先进的软件系统。方案选用高性能主机和存储介质,构成系统硬件设备,同时系统将采用B/S网络架构模式,系统设计更加简单合理;同时,系统前端和后台管理分别采用模块化设计思想,降低了实现难度。本文的重点是设计系统整体框架结构并完成搭建、按设计需求完成各功能模块的开发。使用当前主流技术方案,例如Windows多线程技术、数据压缩转码技术等,提升软件性能。本文还对一些实现方法做出了分析,例如对所选择的浏览器/服务器模式的特点进行了说明,对接口开发,流程设计等进行了阐述。最后,在对本次系统搭建及功能开发梳理总结后,展望了兰州石化公司视频点播系统的二次开发及后续工作。
[Abstract]:For home end users, the transmission of large resources and big data is subject to technical constraints, which fundamentally restricts the application of Internet on demand, and limits the promotion of real-time online on demand technology. However, with the continuous improvement of Internet broadband speed in the 21st century, online data transmission and online video-on-demand technology are more widely used, and the related industries have ushered in new development opportunities. Streaming media resources online play technology is widely used in various industries, including Internet media, online courses, employee training, entertainment, advertising and so on. The network bandwidth of the end user is no longer restricting the transmission of big data and the online playing of video resources. The emergence and popularization of new network media transmission technology has solved the problem of the fluency of online on-demand fundamentally. This paper mainly studies the online VOD system. Based on the brief introduction of related technologies, the characteristics of streaming media resources, the application of technology and the prospect of development, the design and development of the playback system of Shihua City Cinema are discussed and studied. The system compresses the resource file sends the client completes the data reception and plays is the key to realize the Shihua city cinema play system and the above technology can effectively guarantee the fast transmission of the data packets between the network and improve the user experience. On the basis of the theoretical research above, this paper proposes a design scheme based on Windows platform, using advanced streaming media technology, data transmission and general broadcast protocol. On the basis of consulting staff for many times and analyzing demand preference, the software system is designed with superior performance, extended flexible system architecture, and developed software system with reliable performance, reasonable structure and advanced function. The scheme chooses the high performance host and storage medium, constitutes the system hardware equipment, at the same time, the system will adopt the B / S network structure pattern, the system design is more simple and reasonable, at the same time, the system front end and the background management adopt the modularization design idea, It reduces the difficulty of realization. The emphasis of this paper is to design the whole frame structure of the system and complete the building, according to the design requirements to complete the development of each functional module. Using the current mainstream technology solutions, such as Windows multithreading technology, data compression and transcoding technology, to improve software performance. This paper also analyzes some implementation methods, such as the characteristics of the selected browser / server mode, interface development, process design and so on. Finally, after combing and summing up the system structure and function development, the second development and follow-up work of Lanzhou Petrochemical Company Video on demand system are prospected.
