当十年前我头一次听说MPEG4的时候,以为它只能用于移动电视,如现在常说的手机电视、掌中电视等小画面、低码流的多媒体领域。万万没想到,而今H.264(MPEG4)竟然渗透到标准的SDTV和HDTV数字电视中,在卫星、网络等各种传输方式上得到了广泛的应用。半年前,我第一次收到了H.264格式的LUXE-HD高清频道。上个月,又收到了国内首次试播的H.264格式的天盛足球标清频道。以后,一定还会收到更多此类格式的新频道。将来的趋势,AVC(H.264)解压器和传统的MPEG2甚至VC-1(WMV-HD)将组合到一个芯片内,成为各种蓝光、红光等高清碟机以及高清硬盘播放机的标配。这些内容,都是我们最感兴趣的,本栏目将会逐步介绍。
When I first heard of MPEG4 ten years ago, I thought it could only be used for mobile TV, such as mobile TV, palm TV and so on, which are often said now, and low bit rate multimedia. Never imagined, now H.264 (MPEG4) even penetrate into the standard SDTV and HDTV digital TV, in the satellite, network and other transmission methods have been widely used. Six months ago, I first received the LUXE-HD H.264 HD format. Last month, they also received the first test broadcast of the Tian Sheng football standard definition H.264 channel in China. In the future, there will be more new channels in this format. In the future, the AVC (H.264) decompressor and the conventional MPEG2 and even the VC-1 (WMV-HD) will be combined in one chip to become the standard for various Blu-ray and Red light HD disc players and HD hard disc players With These are the things we are most interested in, this section will be introduced step by step.
