1、欧共体调整发展战略新动向 欧共体各国原定的发展路线是:现用PAL、SECAM制地面广播→D_2→MAC制卫星广播→HD—MAC制卫星广播,由D_2→MAC接收机可以兼容收看HD—MAC节目,因此号称为兼容渐进路线。但是,数字电视制式兴起、改进PAL制取得的研究进展以及一些其它因素,导致要对这一路线作修正。欧共体已同意在今后4年推进欧洲宽屏幕电视(W—TV)。值得注意的是其目标唯一对准16:9格式(625行或1250行),而不限死一种制式或广播模式。这一新动向对欧洲发展新一代电视产生了重大影响。
1. New Trends in the Adjustment and Development Strategy of the European Community The original development routes of the countries in the European Community are as follows: terrestrial broadcasting now in use by PAL and SECAM → D_2 → satellite broadcasting made by MAC → satellite broadcasting made by HD-MAC and broadcast by D_2 → MAC receivers Compatible with watching HD-MAC programs, so called evolution compatible route. However, the rise of the digital television system, the progress made in improving the PAL system, and other factors have led to a revision of this line. The European Community has agreed to promote European wide-screen television (W-TV) in the next four years. It is worth noting that its target is uniquely aligned to the 16: 9 format (625 lines or 1250 lines), not limited to a single system or broadcast mode. This new trend has had a significant impact on the development of a new generation of TVs in Europe.
