摘要： A receiver may receive and process broadcasting signals in digital and analog forms. The receiver may include an amplifying input stage, a digital signal processing stage and an analog signal processing stage. The input stage may receive a broadcast signal. The digital signal processing stage may process a received broadcast signal and output a first quality information signal. The analog signal processing stage may process a received analog broadcast signal and outputs a second quality information signal. An evaluation unit may evaluate at least one of the first and second quality information signals and output a control signal to the amplifying input stage.

摘要： This invention provides a diversity system with identification and evaluation of antenna properties. The application also provides a method for selecting an external receiving broadcast diversity antenna. The invention makes a selection of one of the diversity antennas as efficient as possible and is able to adapt the solution found to a variety of practical situations that may arise regarding diversity reception in a vehicle. This may be accomplished by the antenna characteristics being detected and antenna selection made based on the antenna characteristics. Thus, the best reception signal will be automatically selected by the mobile broadcast receiver without human intervention or prolonged waiting time.

摘要： A system for adaptively separating luminance and chrominance components of a color television signal includes a chrominance comb filter comprising a delay network with dual delay elements for providing a combed chrominance component, a bandpass filter for providing a bandpassed chrominance component, and a subtraction circuit. The subtraction circuit subtracts either the combed chrominance component or the bandpassed chrominance component from the television signal to produce a separated luminance component as a function of the phase of signals obtained from the delay network. Illustratively, the subtracter subtracts the bandpassed chrominance component from the television signal in the presence of color transitions in the vertical direction, and in the presence of 180.degree. color transitions.
