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： In a video system, a method and system for cross-chrominance removal using motion detection are provided. A luma motion detector in a motion adaptive deinterlacer may be used to determine a chroma current motion for a pixel in a video frame. The chroma current motion may be modified, based on a chroma motion mechanism comprising of an edge detection, a back-off, and a motion biasing, when the output pixel is found to be in a static chroma area of the video frame. A static chroma threshold parameter may be used to determine whether the output pixel is in a static chroma area. A cross-chroma reduction determined based on the current chroma motion, may be blended in the motion adaptive deinterlacer with a spatial average approximation of the output pixel to remove the cross-chrominance from the output chroma.

The interpolation of a plurality of output pictures may be controlled based on the determined quality. A plurality of original input pictures may be interpolated when the determined quality of the plurality of generated motion vectors is below a threshold value. A plurality of motion compensated pictures may be interpolated when the determined quality of the plurality of generated motion vectors is above a threshold value. A reduced interpolation mode may be utilized if a generated cut-off value is less than an entry threshold value and/or above an exit threshold value.
