摘要

本文介绍了对ATSC数字电视标准提出的改进方案。该方案提供了一种机制，以向后兼容的方式在标准比特流中嵌入新的鲁棒比特流。与标准流相比，鲁棒流具有更高的可见性阈值(TOV)，可以在伪2-VSB模式或E-VSB模式下传输。基于所建议的系统，已经开发了一个原型收发器系统，并正在实地进行测试。

A newly proposed ATSC DTV system for transmitting a robust bit-stream along with the standard bit-stream

This paper describes the proposed improvements to the ATSC DTV standard. The proposal provides a mechanism for embedding a new robust bit-stream in the standard bitstream in a backward compatible manner. The robust stream has a higher threshold of visibility (TOV) compared to the standard stream and can be transmitted either in the pseudo 2-VSB mode or in the E-VSB mode. A prototype transceiver system, based on the proposed system, has been developed and is being tested in the field.
