发明名称 Transmission system minimizing interference in digital transmission.
摘要 A method and apparatus for transmitting a digital television signal which provides audio, video and data packets alternating with training signals. In order to minimize interference to other systems which could occur due to the periodicity of the training signal, randomly selected training signals are inverted prior to combining them with the data packets. <IMAGE>
