摘要

隨著數位行動電視的來臨，如何整合多頻道的資訊成為一項重要的議題，在這個研究中，我們以TI Davinci開發了一個「多頻道數位電視訊息合成及整合平台」，能夠自動合成及整合影片中的訊息，讓觀眾可一邊觀看電視節目，一邊接收各種不同重要的資訊，在這個平台中同時能夠對多餘的資訊加以過濾，讓觀眾可更完整的觀看整個影片，因此，有了這樣的平台將對數位家庭的建構有所助益。

With the recent trend of designing multi-functional digital TV, how to integrate mult-channel information has become an important issue. Thus, in this project, we design and implement a Multi-Channel Digital Television Signal Integration Platform on TI Davinci development board. It can integrate multi signal and generate artificial videos automatically. With this platform, users can not only view television programs but also realize important information. In addition, it can filter out useless information in order to view the complete videos for users. Therefore, the development of digital home is benefited from such a platform.
