随着科技的发展,电视也早就实现了基本的普及,而电视所依赖的科技也从基本的图像显示上升到了以数字电视为主。数字电视是当今电视发展的主流方向,且数字电视的发展已引起了工业界和学术界的普遍关注,其中数字电视的科技基础视频压缩编码技术则成为了科学届如今的研究热点。当下,高清数字电视已步入市场,而高清数字电视更是引起了各国研究的兴趣,之所谓高清电视,因为它具有超高的分辨率,而正因为它的高分辨率的特点,造成了它的传输的信号数据量极其庞大,这就要求高清数字电视要采用新的视频压缩编码技术。原本的视频编码标准是H.264/AVC,经过实践的检验,这种编码标准已无法满足高清数字电视的需求。本文将介绍新一代的视频编码标准HEVC的各个模块以及HEVC在高清数字电视中的应用。
With the development of science and technology, television has long realized its basic popularity. The technology on which television depends has also risen from basic image display to digital television. Digital television is the mainstream direction of the development of television today, and the development of digital television has aroused widespread concern in industry and academia. Among them, the technology of video compression and encoding based on digital television has become the hot topic in science nowadays. At present, high-definition digital television has entered the market, and high-definition digital television has aroused the interest of all countries, the so-called high-definition television because of its high resolution, and precisely because of its high-resolution features, resulting in Its transmission of signal data is extremely large, which requires high-definition digital television to adopt a new video compression coding technology. The original video coding standard is H.264 / AVC, after the test of practice, this coding standard has been unable to meet the needs of high-definition digital TV. This article will introduce the new generation of video coding standard HEVC modules and HEVC in high-definition digital television applications.
