【摘要】：SMG正在建設(shè)面向下一代數(shù)字電視播控平臺，以滿足將來業(yè)務(wù)需要，并適應(yīng)未來的數(shù)字電視發(fā)展要求。隨著廣電高清浪潮的到來，SMG高清頻道已于去年正式開播，而高清廣告上載及備播系統(tǒng)也是高清頻道播出的重要組成部分，不過由于現(xiàn)有的廣告?zhèn)洳ハ到y(tǒng)是多年前搭建的，且只支持標(biāo)清的廣告業(yè)務(wù)，無法滿足如今播控平臺的新需求，所以建設(shè)一套支持高清廣告上載及備播的新系統(tǒng)勢在必行。 針對原有系統(tǒng)存在的缺點，如分布式存儲系統(tǒng)、內(nèi)容共享性差、業(yè)務(wù)流程管理松散、缺乏高清設(shè)備、無法支持前端的高清播出等，本課題的研究目標(biāo)是設(shè)計出一套能克服上述缺點，并且符合將來高清廣告業(yè)務(wù)需求的新系統(tǒng)。 本文在分析了原有系統(tǒng)存在的不足之后，針對高清業(yè)務(wù)需求，對所需設(shè)計的新系統(tǒng)做了合理的定位。本文設(shè)計的廣告?zhèn)洳ハ到y(tǒng)，是存在于廣告部門的廣告管理系統(tǒng)和播出部門的新建的播出系統(tǒng)之間的一個相互銜接的系統(tǒng)，其最主要功能是完成廣告播出單轉(zhuǎn)單和素材備播的工作。 其次，本文對新系統(tǒng)進(jìn)行了業(yè)務(wù)流程設(shè)計，優(yōu)化了整體業(yè)務(wù)流程，使其合理有序，以解決舊系統(tǒng)流程管理松散的問題。其主要工作如下：確定業(yè)務(wù)范圍；劃分業(yè)務(wù)角色；設(shè)計業(yè)務(wù)數(shù)據(jù)流；設(shè)計各個關(guān)鍵業(yè)務(wù)場景及流程。另外，對于廣告客戶在實際操作過程中，提出的一些關(guān)于臨時更換廣告素材內(nèi)容的新需求，，本文設(shè)計了一套靈活的高標(biāo)清素材覆蓋上載策略來應(yīng)對此類問題。 然后，本文根據(jù)不同的業(yè)務(wù)流程，設(shè)計了相應(yīng)的應(yīng)用子系統(tǒng)，以確保各個業(yè)務(wù)場景能合理實現(xiàn)。大致分為以下幾塊：轉(zhuǎn)單子系統(tǒng)；上載子系統(tǒng)；內(nèi)容處理子系統(tǒng)；下載子系統(tǒng)以及WEB管理子系統(tǒng)。針對新廣告?zhèn)洳ハ到y(tǒng)中可能存在的一些隱患，本文提出了相應(yīng)的建議以及解決方案。在系統(tǒng)的遷移傳輸環(huán)節(jié)中，可能存在文件傳輸錯誤以及被人篡改的問題，因此本文提出在新系統(tǒng)的遷移環(huán)節(jié)中加入MD5碼的校驗，以確保素材文件遷移的準(zhǔn)確性。 此外，本文對整個廣告?zhèn)洳ハ到y(tǒng)進(jìn)行了集成設(shè)計，主要對新系統(tǒng)進(jìn)行了系統(tǒng)規(guī)模的分析，包括存儲量、存儲帶寬的分析建議等，并設(shè)計了系統(tǒng)的網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)。根據(jù)新系統(tǒng)的數(shù)字化特點，本文針對原有演播室廣告播出業(yè)務(wù)的不足，提出了一套關(guān)于演播室廣告監(jiān)播的創(chuàng)新方案。 本文設(shè)計的新廣告?zhèn)洳ハ到y(tǒng)優(yōu)化了廣告播出的工作流程，提高了廣告的播出質(zhì)量、效率和安全性，具有很強(qiáng)的實用性。系統(tǒng)設(shè)計符合數(shù)字化、文件化、網(wǎng)絡(luò)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.
