A system for controlling an RF gain of a receiver that reduces a time taken to maintain an input signal level at an optimum dynamic range is provided. The system includes a tuner that receives a radio frequency (RF) signal and down-converts the RF signal to an intermediate frequency (IF) signal, and a demodulator. The tuner includes a radio frequency programmable gain amplifier (RF_VGA), a filter and an IF programmable gain amplifier (IF_VGA). The demodulator includes an analog to digital converter (ADC), and an Automatic Gain Control (AGC) unit that (i) receives a digital signal and an IF gain of the IF_VGA. The ADC samples a filtered IF signal under oversampling conditions to obtain an oversampled signal that includes an in-band signal and an out-of-band signal. The AGC unit (ii) controls the RF_VGA, the IF_VGA and (iii) measures an RF energy of the RF signal.

A method, including executing instructions recorded on a non-transitory computer-readable storage media using at least one processor, may include loading a component from a repository in a first user interface, notifying a second user interface that the component is loaded in the first user interface, performing one or more checks on the component using a check engine and generating one or more check results, storing the check results in a buffer and displaying the check results in the second user interface. The first user interface, the second user interface, the buffer and the check engine may be integrated modules of a single application.

A Television (TV) receiver for faster channel switch times between a plurality of broadcasting TV channels with reduced latency in overall demodulation cycle for multiple demodulation standards is provided. The TV receiver includes a tuner that receives the broadcasting TV channels from a broadcasting system, performs a tuning operation, and sets a desired frequency for each of the broadcasting TV channels during a channel scan operation. A demodulator demodulates each of the broadcasting TV channels and acquires one or more acquisition channel parameters of each of the broadcasting TV channels during the channel scan operation. An application processor is coupled to the demodulator via a low throughput interface. The application processor performs a read operation and a write operation of the acquisition channel parameters to memory mapped registers on the demodulator when a channel status switches from a first state to a second state.
