DEVICE AND METHOD FOR CORRECTING ERROR OF DIGITAL TELEVISION SIGNAL UNNECESSARY FOR OVERHEAD BIT |
摘要 |
<p>Method and apparatus for detecting and significantly correcting bit errors in a pulse code modulated television signal which recognizes the unique spectral characteristics of isolated bit errors in a digital bit stream, which generate spectral energy outside the frequency band of the video signal, and utilizes that energy to detect and correct errors without the use of overhead bits.</p> |
