【摘要】：隨著電視臺業(yè)務的不斷發(fā)展以及數(shù)字電視高清化、網(wǎng)絡化的發(fā)展，電視臺的節(jié)目數(shù)據(jù)量與日俱增，所有的電視臺都在從傳統(tǒng)的磁帶化存儲向無帶化發(fā)展。黑龍江電視臺為了適應發(fā)展的需要，也由于現(xiàn)有標清播出系統(tǒng)建設運行時間已達7年，設備老化，系統(tǒng)結構和播出手段遠遠落后于目前的技術發(fā)展。因此，我們對現(xiàn)有的播出系統(tǒng)做了一個基于全臺網(wǎng)的建設和改造工作，，而做為后臺備播緩存庫的二級存儲系統(tǒng)是此高清播出系統(tǒng)中的重要組成部分，是實現(xiàn)無帶化播出的基礎，對此也進行了全新的設計與搭建，以滿足海量視音頻數(shù)據(jù)的增加并實現(xiàn)電視臺播出系統(tǒng)與制作系統(tǒng)、媒資系統(tǒng)間的視音頻共享。 本文應用網(wǎng)絡存儲技術對黑龍江電視臺高清播出系統(tǒng)的二級存儲系統(tǒng)進行設計與建設。通過對直接連接存儲DAS、網(wǎng)絡附加存儲NAS、存儲區(qū)域網(wǎng)SAN以及SAN與NAS融合等網(wǎng)絡存儲技術的優(yōu)缺點的比較，進一步分析確定適合黑龍江電視臺二級存儲系統(tǒng)的相關技術，以使二級存儲系統(tǒng)的構建合理，系統(tǒng)性能可靠、高效。 論文首先分析了黑龍江電視臺高清播出二級存儲系統(tǒng)的需求，并對要構建的二級存儲系統(tǒng)的相關產品進行了調研，從而開始對二級存儲系統(tǒng)的設計。先通過計算得到了二級存儲系統(tǒng)的存儲容量和帶寬并確定所選二級存儲系統(tǒng)產品，重點探討了二級存儲系統(tǒng)的網(wǎng)絡架構和網(wǎng)絡拓撲，確定該系統(tǒng)的主備存儲系統(tǒng)應用策略、分區(qū)訪問策略、存儲管理策略以及通過二級存儲系統(tǒng)進行備播時的遷移策略，通過以上策略的制定，最終完成從節(jié)目生產系統(tǒng)、媒資系統(tǒng)和廣告系統(tǒng)到二級存儲系統(tǒng)的備播流程。 目前黑龍江電視臺高清播出二級存儲系統(tǒng)已經(jīng)投入運行2年。此系統(tǒng)在實現(xiàn)無帶化存儲上起著重要作用，系統(tǒng)運行2年性能安全、穩(wěn)定、可靠、易于管理和維護，達到了設計目標，對其他電視臺有著重要的借鑒意義。
[Abstract]:With the continuous development of television business and high-definition digital TV, the development of the network, the program data of television and television all grow with each passing day, with the development from traditional tape storage. Heilongjiang TV station without the need to adapt to the development, but also by the existing SDTV broadcast system operating time for over 7 years, aging equipment, system structure and broadcast means far behind the current technological development. Therefore, we made the existing broadcasting system based on a whole network of the construction and renovation work, the two level storage system as the background. The buffer library is an important part of the HD broadcast system. No, is the basis of the broadcast, which was also carried out and set up a new design, in order to meet the increasing mass of video and audio data and broadcast system and production system of television media information system. Video and audio sharing.
The two level storage system using HD network storage technology in Heilongjiang TV broadcast system design and construction. Based on the direct attached storage DAS network attached storage NAS, comparing the advantages and disadvantages of the storage area network SAN and SAN and NAS fusion network storage technology, further analysis to determine the related technology for Heilongjiang TV two the storage system, so that the construction of two level storage system is reasonable, reliable, and efficient.
This paper first analyzes the Heilongjiang TV broadcast HD two level storage system, and related products on the two level storage system to be constructed for the research, thus begin the design of two level storage system. First obtained by calculating the storage capacity and bandwidth of two level storage system and determine the selected product two level storage the system, focusing on the two level storage system network architecture and network topology, determine the strategy by the main storage system using the system partition, access strategy, storage management strategy and through the two level storage system. The migration strategy, through the development of the above strategies, the final completion of the program from the production system, media information system and the advertising system to the two level storage system backup process.
At present, Heilongjiang TV broadcast HD two level storage system has been put into operation for 2 years. This system realizes non tape storage system plays an important role in 2 years of operation performance and safety, stable, reliable, easy maintenance and management, to achieve the design objectives, have important reference significance to other TV stations.
