Methods and apparatus are described for receiving digital television signals where the receiver is capable of demodulating and demultiplexing the digital television signals from multiple, independent transmission channels. The preferred embodiment of the present invention provides for a Dual Channel Digital TV Receiver which receives signals from two independent transmission channels. In order to address each of the digital television signals from the two independent transmission channels, the Dual Channel Digital TV Receiver of the preferred embodiment of the present invention includes two independent paths for channel demodulation and transport stream demultiplexing. Thus, within the Dual Channel Digital TV Receiver of the preferred embodiment of the present invention, a signal from each of the transmission channels are received, decoded and sent for further processing or viewing, as desired by the user. By providing this dual channel signal processing capability, the Dual Channel Digital TV Receiver of the preferred embodiment allows for versatile program viewing capabilities, including but not limited to, allowing the user to view a program from any one of the transmission channels being accessed, allowing for the recording of programs from one or multiple transmission channels to a digital storage device (which digital storage device may be a part of the Dual Channel Digital TV Receiver), allowing the user to view a program from one transmission channel while recording programs from one or more transmission channels, replaying previously recorded programs, and replaying previously recorded programs while recording programs of one or more transmission channels.
