【摘要】：SMG正在建设面向下一代数字电视播控平台，以满足将来业务需要，并适应未来的数字电视发展要求。随着广电高清浪潮的到来，SMG高清频道已于去年正式开播，而高清广告上载及备播系统也是高清频道播出的重要组成部分，不过由于现有的广告备播系统是多年前搭建的，且只支持标清的广告业务，无法满足如今播控平台的新需求，所以建设一套支持高清广告上载及备播的新系统势在必行。针对原有系统存在的缺点，如分布式存储系统、内容共享性差、业务流程管理松散、缺乏高清设备、无法支持前端的高清播出等，本课题的研究目标是设计出一套能克服上述缺点，并且符合将来高清广告业务需求的新系统。本文在分析了原有系统存在的不足之后，针对高清业务需求，对所需设计的新系统做了合理的定位。本文设计的广告备播系统，是存在于广告部门的广告管理系统和播出部门的新建的播出系统之间的一个相互衔接的系统，其最主要功能是完成广告播出单转单和素材备播的工作。其次，本文对新系统进行了业务流程设计，优化了整体业务流程，使其合理有序，以解决旧系统流程管理松散的问题。其主要工作如下：确定业务范围；划分业务角色；设计业务数据流；设计各个关键业务场景及流程。另外，对于广告客户在实际操作过程中，提出的一些关于临时更换广告素材内容的新需求，，本文设计了一套灵活的高标清素材覆盖上载策略来应对此类问题。然后，本文根据不同的业务流程，设计了相应的应用子系统，以确保各个业务场景能合理实现。大致分为以下几块：转单子系统；上载子系统；内容处理子系统；下载子系统以及WEB管理子系统。针对新广告备播系统中可能存在的一些隐患，本文提出了相应的建议以及解决方案。在系统的迁移传输环节中，可能存在文件传输错误以及被人篡改的问题，因此本文提出在新系统的迁移环节中加入MD5码的校验，以确保素材文件迁移的准确性。此外，本文对整个广告备播系统进行了集成设计，主要对新系统进行了系统规模的分析，包括存储量、存储带宽的分析建议等，并设计了系统的网络拓扑结构。根据新系统的数字化特点，本文针对原有演播室广告播出业务的不足，提出了一套关于演播室广告监播的创新方案。本文设计的新广告备播系统优化了广告播出的工作流程，提高了广告的播出质量、效率和安全性，具有很强的实用性。系统设计符合数字化、文件化、网络化的要求。
[Abstract]:SMG is building the next generation digital TV broadcast control platform to meet the needs of the future business and to meet the requirements of the future development of digital television.With the arrival of the high definition wave of radio and television, the SMG HD channel was officially launched last year, and the HD advertising upload and standby broadcast system is also an important part of the HD channel broadcast. However, since the existing advertising standby system was built many years ago,And only supporting the standard advertising business, can not meet the new demand of the broadcast control platform, so it is imperative to build a new system to support the upload and broadcast of high-definition advertising.In view of the shortcomings of the original system, such as distributed storage system, poor content sharing, loose business process management, lack of high-definition equipment, unable to support front-end high-definition broadcast, etc.The purpose of this paper is to design a new system which can overcome the above shortcomings and meet the needs of HD advertising business in the future.After analyzing the shortcomings of the original system, this paper makes a reasonable positioning for the new system which needs to be designed according to the requirement of high definition service.The advertisement preparation system designed in this paper is a connecting system between the advertising management system of the advertising department and the new broadcast system of the broadcasting department.Its main function is to complete the advertisement broadcast single transfer and material preparation work.Secondly, this paper designs the business process of the new system, optimizes the whole business process, makes it reasonable and orderly, in order to solve the problem of loose process management in the old system.The main work is as follows: to determine the business scope; to divide the business role; to design the business data flow; to design the key business scenarios and processes.In addition, in order to deal with this kind of problem, this paper designs a set of flexible high standard and clear material cover upload strategy to deal with some new requirements of temporary replacement of advertising materials put forward by advertisers in the actual operation process.Then, according to the different business processes, this paper designs the corresponding application subsystem to ensure that each business scenario can be realized reasonably.Roughly divided into the following sub-system: subsystem; upload subsystem; content processing subsystem; download subsystem and WEB management subsystem.In view of some hidden troubles in the new advertisement preparation system, this paper puts forward the corresponding suggestions and solutions.In order to ensure the accuracy of the transfer of material files, there may be problems of file transfer errors and tampering in the transfer link of the system. Therefore, this paper proposes to add MD5 codes to the transfer link of the new system to ensure the accuracy of the transfer of the material files.In addition, the integrated design of the whole advertising and broadcast system is carried out in this paper. The system scale of the new system is mainly analyzed, including the analysis of storage capacity and storage bandwidth, and the network topology of the system is designed.According to the digitization characteristics of the new system, this paper puts forward a set of innovative scheme for the supervision and broadcast of the studio advertisement in view of the shortcomings of the original studio advertisement broadcasting business.The new advertisement preparation system designed in this paper optimizes the work flow of advertisement broadcasting, improves the quality, efficiency and safety of advertisement broadcast, and has strong practicability.The system design meets the requirements of digitization, documentation and networking.
