A television receiver includes a frequency conversion circuit, an analog-to-digital converter, a signal processor, and a signal output circuit. The frequency conversion circuit receives an input RF signal in one of several television signal formats and converts the input RF signal to an intermediate frequency signal. The analog-to-digital converter samples the intermediate frequency signal and generates a digital representation thereof. The signal processor processes the digital representation of the intermediate frequency signal in accordance with the television signal format of the input RF signal and generates digital output signals indicative of information encoded in the input RF signal. Finally, the signal output circuit receives the digital output signals from the signal processor and provides one or more output signals corresponding to the digital output signals. The signal output circuit can be configured to provide output signals corresponding to an analog television format or a digital television format or both.

Systems and methods for processing signals in a communication system are disclosed and may include demodulating a wirelessly received inband signal and a wirelessly received out-of-band signal via a DTV receiver. One or more TV channels may be generated based on the demodulation of the wirelessly received inband signal and a wirelessly received out-of-band signal. The received inband signal may include a VSB signal, a NTSC signal and/or a QAM signal. The processing may also include determining whether the wirelessly received inband signal includes an analog signal or a digital signal. The digital signal may be error corrected, and the error corrected digital signal may be equalized. The analog signal may be decoded, and an audio output may be generated based on the decoding of the analog signal.

A display is capable of displaying images in response to signals of a plurality of signal formats. The display includes a controller that is coupled to a plurality of image data interfaces. When the plurality of image data interfaces are simultaneously operating, the controller selects one of the plurality of image data interfaces according to preference variables associated with each of the plurality of image data interfaces. Each of the preference variables may indicate a relative priority of an image data signal format associated with the corresponding image data interface. In addition, each of the preference variables may indicate one or more performance metrics associated with the quality of image data signals received from the corresponding image data interface.

A digital TV receiver 2 receives digital TV broadcasts and an analog TV receiver 1 receives analog TV broadcasts. A switching control 6 switches between either digital or analog signals to a speaker 7 and a display 8 , according to the conditions of received digital and/or analog broadcast waves. Digital broadcast outputs, such as images, cannot be obtained if the field intensity of received broadcast waves is too low for the application of error correction to them. Even in that event, the present equipment can continue image outputs by switching to the analog broadcast. Preferably, the switching control 6 uses the packet error rate during the demodulation of received digital broadcast signals as the index of the conditions of the received waves to perform an output switch between digital and analog broadcasts, according to the error rate.

A receiver (100) requiring only a single IF SAW filter (120) and IF amplifier (126) receives signals in both analog format and in digital format, such as the NTSC, PAL and SECAM analog television signal formats and the ATSC and DVB digital television signal formats. IF signals from the IF amplifier (126) are sub-sampled to digital signal form (130) and are processed by respective analog format (140) and digital format (150) processors. Control circuitry (160) responsive to the presence of certain unique components of the signals in analog format and digital format determine which of the analog format and digital format processors is producing valid data and selects the valid data to be utilized. In a television receiver (100), the unique components of the signals may include carrier signals, synchronization signals, pilot signals and symbol timing, and valid data is applied to a television display.
