摘要： A method and system is provided, which may detect digital QAM, VSB and analog TV signals in a faster and more efficient manner than conventional systems. The system and method may be deployed in, for example, cable TV set-top boxes, cable TV modems and television set receivers, which may be coupled to a cable TV or off-the-air terrestrial network. Power measurements of the RF carriers found in a cable TV channel may be utilized to determine whether a digital QAM signal, digital VSB signal, or an analog signal is present in a TV channel. In this regard, it is not necessary for a receiver to demodulate, lock, synchronize, decode and/or validate any video or audio information or digital bit stream in order to detect digital QAM, digital VSB and analog TV signals, or not signal at all. Accordingly, the process of detecting digital QAM, digital VSB and analog TV signals is shortened and simplified.

摘要： System and methods for processing signals in a television system are disclosed and may include measuring relative power of RF carriers over a full bandwidth of one or more received TV channels. The method may also include determining based on the measured relative power, whether the one or more received TV channels includes a digital component or an analog component without demodulating the received TV channel. It may be determined whether the one or more received TV channels includes a digital component or an analog component without synchronizing and/or decoding the one or more received TV channels. The method may further include tuning to the one or more received TV channels. It may be determined whether an applied power gain for the one or more received TV channels is a maximum power gain.

摘要： Aspects of a method and system for processing signals in a television system using a subset of receive operations for detecting digital and analog television signals are provided. The system and method may be deployed in, for example, cable TV set-top boxes, cable TV modems, and television receivers, which may be coupled to a cable TV or over-the-air terrestrial network. Performing only a subset of receiver operations may allow detection of the type of signal; for example digital QAM, digital VSB, or analog; present in a television channel. In this regard, it is not necessary to generate and validate a bit stream in order to detect if a signal is present and/or the type of signal present.

摘要： A second coaxial-connector may be added to a TV receiver that directly samples digital or analog format TV signals, which may be received via a first coaxial-connector. The second coaxial-connector may enable backwards compatibility with one of plurality of available consumer audiovisual devices, wherein Audio/Video (A/V) analog and/or digital modulation format feeds from the consumer audiovisual device may be inputted directly into the TV receiver via the second coaxial-connector. The A/V feed from the consumer audiovisual devices may be demodulated via a common demodulator for similarly modulated TV signals in the TV receiver. Filtering and/or amplification of the local A/V feed may be performed via dedicate components; however, analog-to-digital conversion of the local A/V feed may either be performed via the dedicated converter or via a common-path converter. The local A/V feed may also be demodulated directly, via a dedicated demodulator.
