T-DMB的互動性場景的解碼與呈現

The decoding and presentation of T-DMB interaction scene

指導教授 : 尤信程

摘要


T-DMB為韓國的數位電視規格,與現今歐規的DVB-T相比,額外提供了場景資料,此技術是使用規格MPEG-4 part11:Binary format for scene (BIFS,二元場景描述)。 MPEG-4主要目的是定義一個高壓縮率的互動性多媒體系統,其規格是由十九個部分組成的,包括系統、視訊、聲音、確認測試軟體、參考軟體、二元場景描述及多媒體傳輸架構等。本論文的研究範圍以「二元場景描述」為主題,二元場景描述部分提供一個具有互動性的場景,以展現使用者與各種媒體物件的互動性。二元場景描述分別定義了場景編碼、場景描述、場景路由機制。 本論文自行設計一二元場景描述的解碼與管理的系統,配合影像資料最後可供合成繪圖器來繪製出一互動式場景。

T-DMB is South Korea's digital TV specifications, with the current regulations of the European DVB-T, compared the scene to provide additional information, this technology is to use standard MPEG-4 part-11: scene description and application engine. The main objective of MPEG-4 is to define an interactive multimedia system with high compression ratio. It includes twenty-one parts, which are system, visual, audio, conformance testing, reference software, delivery multimedia integration framework , scene description and application engine, etc. This thesis studies the scene description and application engine part, which provide the interactive scenes. The interactive scenes can handle the user input event and pass the message which the event trigged to changing the scene. The scene description and application engine part defines scene description. This thesis designed a binary scene description decoding and managing system. It can be rendering a interactive scene for render with video data.
