Abstract

Digital Television Transmission is the streaming of impairment free digitally processed and multiplexed signals in a binary on/off bit sequences to all receiving locations within coverage area [1]. Television signal whether digital or analogue can be delivered through three main platforms; cable, satellite and terrestrial wireless. Digital Cable Television Transmission is the transmission of television signals to receivers through direct cable connection from an underground cable network with improved interactivity and has a higher multiplex capacity compared to terrestrial digital television [2]. Digital Satellite Television (TV) transmission is the transmission of digital television signal from a base station towards a satellite which is then processed and converted into frequency range that can be viewed using parabolic antenna [3] and has the benefit of reduced transponder cost and increased channel capacity for given transponder space [2]. Digital Terrestrial television transmission is seen as the most important means of delivery of digital television signals, provides real and nonreal-time delivery of content, point-to-multipoint and one to many architecture, delivering geographically local content and supports receivers that can move, free to air and subscription services [4]. The terrestrial digital compression technology allows many channels to be broadcasted with the same amount of spectrum used by one analogue channel and receiving of digital signals on conversional television aerial by conversion into analogue by a set-top box (STB) or viewed with integrated digital television set (IDTV) [2]. Digital Terrestrial Television is the transmission of digital television signals from a ground based transmitter operating in the UHF or VHF band which is radiated as radio waves and are received using a UHF or VHF antenna [1]. Digital television transmission is the new wave of broadcasting and the future of television broadcasting [4]. It has naturally evolved from Analogue Television Transmission and involves the process of generating television contents, editing, finalizing, storing, transmitting and receiving just like in the analogue system. In digital television transmission, all the processes are digital based; image, sound and information are generated and received as digital signals unlike Analogue Television Transmission where content generation and transmission are through analogue signals [5].
加纳数字电视传输技术现状的检验:以Knet有限公司为例
数字电视传输是以二进制开/关位序列将无损伤的数字处理和多路复用信号流式传输到覆盖区域[1]内的所有接收位置。电视信号无论是数字还是模拟都可以通过三个主要平台传送;有线、卫星和地面无线。数字有线电视传输是将电视信号从地下有线网络通过直接电缆连接传输到接收器,与地面数字电视相比,具有更好的交互性和更高的多路传输能力。数字卫星电视(TV)传输是从基站向卫星传输数字电视信号,然后对其进行处理并转换为可使用抛物面天线[3]观看的频率范围,并且具有降低转发器成本和增加给定转发器空间[2]的信道容量的好处。数字地面电视传输被视为最重要的数字电视信号传输方式,提供真实和非实时的内容传输,点对多点和一对多架构,提供地理位置上的本地内容,并支持可移动的接收器,免费到空中和订阅服务[4]。地面数字压缩技术允许多个频道以一个模拟频道所使用的相同频谱进行广播,并通过机顶盒(STB)转换成模拟信号或通过综合数字电视(IDTV)[2]观看转换电视天线上的数字信号。数字地面电视是从在UHF或VHF波段工作的地面发射机传输数字电视信号,这些信号以无线电波的形式辐射,并使用UHF或VHF天线[1]接收。数字电视传输是广播的新浪潮,是电视广播的未来。它是由模拟电视传输自然演变而来的,与模拟系统一样,包括电视内容的产生、编辑、定稿、存储、发送和接收等过程。在数字电视传输中,所有的过程都是基于数字的;与模拟电视传输不同,图像、声音和信息以数字信号的形式产生和接收,而模拟电视传输通过模拟信号产生和传输内容。
