Abstract

Provided is a remote control comprising a housing, a keyboard (20) mounted on the housing, a processor (106) electrically connected to the keyboard (20), an analog-digital converter (103) and a high-frequency wireless transmission unit (108) electrically connected to the processor (106), a sampling circuit (102) electrically connected to the analog-digital converter (103) and a microphone interface (30) electrically connected to the sampling circuit (102). Also disclosed is a television system. The remote control and television system in the present solution are simple to operate and can satisfy user'"'"'s multi-function requirements.

Claims

1. A remote control comprising:

a housing;

a keyboard mounted on the housing;

a processor electrically connected with the keyboard;

a memory electrically connected to the processor and configured to store corresponding relationships between digital signals and control instructions;

a microphone interface configured to receive an analog voice command;

a sampling circuit and an analog-digital converter electrically connected with the processor and the microphone interface, and configured to covert the analog voice command to a digital signal; and

an ultra-high frequency wireless transmission unit electrically connected with the processor,

wherein the processor is configured to;

correspond the digital signal to a control instruction according to the corresponding relationships stored in the memory and send out the control instruction via the ultra-high frequency wireless transmission unit when the remote control is in a voice control operation mode, and

recognize, via a voice recognition engine, the digital signal as a word from a human language and send out the word via the ultra-high frequency wireless transmission unit when the remote control is in a voice recognition operation mode.

2. The remote control of claim 1, further comprising a wireless network processing chip electrically connected with the processor, the processor further configured to access a network via the wireless network processing chip to recognize the word corresponding to the digital signal when the remote control is in the voice recognition operation mode.
