Editing and compressing HDTV videos for storage and transmission over Internet

摘要

Because of the lacks in analogic television signal, researches proposed High Definition Television (HDTV), a new approach to transmit the television signal with higher definition. HDTV has quite better image quality than traditional TV. The recent transition to broadband access networks allows multimedia and TV services for Internet users, so it is needed an analysis and an evaluation of HDTV compression codecs for its storage and transmission over Internet. In this paper, we will show how to create a video with HDTV properties. Then, we will choose an adequate codec for HDTV compression to measure the compression gain, the compressed file size and the time needed to compress a second of video.
