Abstract: A voice control device includes a receiving circuit, a voice processing circuit, a memory controller and a main processing circuit. The receiving circuit sequentially receives first voice data and second voice data, and stores the same in a first memory. The voice processing circuit reads the first voice data from the first memory, and generates a control signal when the first voice data includes a predetermined command. The memory controller reads the second voice data from the first memory according to the control signal, and stores the second voice data in a second memory. The main processing circuit reads the second voice data from the second memory according to the control signal so as to perform voice recognition.

Abstract: A television signal processing circuit includes an audio/video (AV) signal generating circuit, an intermediate frequency (IF) mixer, a first filter, a radio-frequency (RF) mixer, a second filter and a digital-to-analog converter (DAC). The AV signal generator generates a digital AV signal. The IF mixer converts the digital AV signal to an IF AV signal. The first filter filters the IF AV signal to generate a filtered IF AV signal. The RF mixer converts the filtered IF AV signal to an RF AV signal. The second filter filters the RF AV signal to generate a filtered RF AV signal. The DAC converts the filtered RF AV signal to an analog AV signal and transmits the analog AV signal to an antenna.
