摘要

数字化是目前电视广播的趋势,在赞比亚和世界各地都是如此。国际电信联盟(ITU)将2015年定为全球所有广播电台实现数字化的一年,目的是通过提高频谱效率,提高信号质量,增加广播传输网络的容量。尽管数字移民带来了这些和许多其他优势,但赞比亚尚未意识到实施数字移民的全部好处。正是在这种背景下,进行了这项研究,以评估数字移民进程的挑战及其在赞比亚的好处。重点是评估电视数字移徙的执行过程;考察从模拟技术转向数字技术的挑战及其好处。为此,我们对300名对流程有直接影响的利益相关者进行了定量研究,以确定他们的观点。收集的数据使用社会科学统计软件包(SPSS)进行分析,以对迁移过程的挑战及其益处进行分类。结果表明,公众缺乏认识是所遇到的一个主要挑战。此外,数字移徙基础设施不足,加上移徙进程资金不足,阻碍了这一进程。然而,该研究也证实,该国从模拟广播向数字广播的迁移中受益。值得注意的包括;传输质量,改进的内容传送,以及观众同时观看多个电视频道的能力,从而在其他好处中给予他们更好的观看乐趣。鉴于数字移民给国家带来的挑战和好处,该研究建议应制定深思熟虑的政策,以确保数字移民所需的基础设施随时可用,政府应提高公众对数字移民过程重要性的认识,以允许更多公众参与。

An Analysis of the Challenges and Benefits of Digital Migration in Zambia
Digitization is the current trend in Television broadcasting, both in Zambia and the world over. The International Telecommunication Union (ITU), set 2015 as the year for the entire broadcasting stations in the world to go digital in order to have better signal quality and increase in the capacity of broadcast transmission networks by improving spectrum efficiency. Despite these and many other advantages that come with digital migration, Zambia is yet to realize the full benefits of digital migration implementation. It’s against this background that the study was conducted to assess the challenges of digital migration process and its benefits in Zambia. The emphasis was on assessing the television digital migration implementation process; examine the challenges of switching from analogue to digital technology and its benefits. To this effect, a quantitative research design was used on a sample of 300 stakeholders who had direct influence on the process to determine their views. The data collected was analysed using Statistical Package for Social Sciences (SPSS) to categorise the challenges of the migration process and its benefits. The results established that lack of awareness by the public was a major challenge was encountered. In addition, inadequate infrastructure for digital migration coupled with inadequate funding towards the hindered the process of migration. However, the study also established that the country has benefited from migrating from analog to digital broadcasting. Notable ones include; quality of transmission, improved content delivery, and ability of the viewers to view more than one TV channel at once thereby giving them a better viewing pleasure among other benefits. In view of the challenges and benefits of the digital migration to the country, the study recommends that deliberate policies should be put in place to ensure that the infrastructure needed for the digital migration are readily available and that Government should create public awareness with regards to the importance of the digital migration process to allow for more public participation.
