| 摘 要： | 本文论述了现行电视系统的缺陷。在概述几种下一代电視制式的基础上,作者提出了一种HVBL制式和协调地发展地面传输和卫星广播的“兼容过渡”途径。HVBL制是一种具有提高的分解力与扩展的幅型比并与PAL/D制完全兼容的制式。

| Abstract: | Based on the analysis of the deficiencies of current TV system and the performance of several systems of the coming generation TV. an HVBL system and a "compatible transition" approach to the coordinate development of the terrestrial transmission and satellite broadcasting. The HVBL system with an increased resolution and extended aspect ratio is fully compatible with PAL/D system. |
