數位電視自動播岀系統壓縮技術無帶化環境之研究

對於電視台而言，數位化的最終目的在於簡化內部流程，可以以最低的成本並透過影音數位化建立擁有龐大經濟效益的數位資產以達到最高的收益，因此以21世紀如此競爭的時代，無帶化環境對電視台運作而言，可說是刻不容緩的。電視台系統全面數位化的建設是一項涵蓋面相當廣泛的系統工程，其中更大量應用了最新的廣播電視及IT 技術，但也存在著諸多技術困難點有待克服。而在建立基於全程影音數位檔案化的電視台業務流程中，實現各系統的互聯互通已經成為不可逆轉的技術發展趨勢。由於電視台的產製與播岀的需求不同，必須透過數位影像壓縮格式的整合，才能達成電視台無帶化環境。本論文針對數位電視自動播岀系統壓縮技術期望能透過系統整合的方式達成電視台無帶化環境建置。傳輸頻寬、儲存內容及設備整合為電視台無帶化環境最主要的關鍵。

For TV station, the final goal of digitization is simplifies internal workflow. By digitizing video and audio, we can have digit assets which have huge economic efficiency with the lowest cost to achieve the highest income. To achieve that in a competitive age like 21st centuries. Building tapeless environment is already urgent for TV station. The fully digitization of TV system is a project that involve a lot of technology(broadcast, television, and IT). At the same time, there are many technical problems still not solve. In the digitization process of television station workflow, the communication and integration between equipment have become a trend. Due to the demand is different that the television station produces and broadcast programs, they must rely on integrating digital images compressions format to achieve tapeless environment. This paper will direct the compression technologies which though this method will create a tapeless environment. The transmission bandwidth, storage content and the equipment conformity will be the key issue to this success.
