    • A system (200) and method (300) provide an efficient communication system for distributing digital multimedia/HDTV signals to multimedia units in a cellular pattern. The method includes: 1) using at least a first primary wide area-antenna for, where selected, transmitting a digital multimedia/HDTV signal per frequency allocation over at least a portion of a predetermined reception area, wherein a plurality of patterns of cells tesselates the predetermined reception area; and 2) using cell-site antennas having transmitters, each located in a cell, for, where selected, transmitting, when the primary wide area-antenna is deselected, at least a first preselected digital multimedia/HDTV signal over an area of the cell, for providing the HDTV signal to a plurality of digital receivers in accordance with a predetermined scheme, wherein the digital multimedia/HDTV signal is associated with a predetermined frequency allocation.
    • 一种系统(200)和方法(300)提供了一种用于将数字多媒体/ HDTV信号以蜂窝模式分发到多媒体单元的有效的通信系统。 该方法包括:1)至少使用第一主广域天线,用于在选定的情况下,通过在预定接收区域的至少一部分上每频率分配发送数字多媒体/ HDTV信号,其中多个单元格模式镶嵌 预定接收区域; 以及2)使用具有发射机的小区站点天线,每个发射机位于小区中,在被选择的情况下,当主广域天线被取消选择时,至少在小区的区域上的第一预选数字多媒体/ HDTV信号 用于根据预定方案向多个数字接收机提供HDTV信号,其中数字多媒体/ HDTV信号与预定的频率分配相关联。
