Embodiment 1

[0033] This embodiment provides a voice input method for a remote controller, the remote controller is used to control a multimedia terminal, such as figure 1 shown, including:

[0034] 101. Receive voice input by the user and convert the voice into an analog audio signal;

[0035] 102. Convert the analog audio signal into a digital audio signal;

[0036] 103. Perform data compression on the digital audio signal to convert it into compressed audio data;

[0037] 104. Send the compressed audio data to the multimedia terminal.

[0038] In step 104 of this embodiment, the remote controller communicates with the multimedia terminal through wireless transmission. In a specific implementation, radio frequency technology is generally used to send compressed audio data to the multimedia terminal.

[0039] The voice input method of the remote controller described in this embodiment uses the remote controller to perform voice input. The remote controller also has a microphone functio...

Embodiment 2

[0060] An embodiment of the present invention provides a remote controller for controlling a multimedia terminal, such as image 3 As shown, the remote control includes:

[0061] The sound pickup device 12 includes: a sound pickup module 121 and an analog-to-digital conversion module 122, the sound pickup module 121 is used to receive the voice input by the user and converts the voice into an analog audio signal, and the analog-to-digital conversion module 122 is used to convert the Convert analog audio signal to digital audio signal;

[0062] The main control unit 13 is used to perform data compression on the digital audio signal input by the pickup device 12, and convert it into audio compression data;

[0063] The communication unit 14 is configured to send the compressed audio data to the multimedia terminal.

[0064] The pickup module 121 in this embodiment may include one or several pickup heads or microphones, which are used to convert the voice input by the user into...

Embodiment 3

[0071] This embodiment provides a remote controller, such as Figure 4 As shown, the difference from the remote controller described in Embodiment 2 is that

[0072] The remote controller also includes: a remote control device 11, configured to receive an operation instruction input by the user and convert it into screen cursor movement information or control instructions, so as to realize the remote control function of the remote controller;

[0073] The main control unit 13 is also used for, before performing voice input, according to the instruction of opening the sound pickup device received, close the remote control device 11, and turn on the sound pickup device 12 so that the user can perform voice input, and generate a message that the sound pickup device has been turned on simultaneously. In response to the message, the remote controller switches from the normal remote control working mode to the pickup working mode;

[0074] The main control unit 13 is also used for,...

Abstract

The invention discloses a voice input method of a remote controller, the remote controller and a multimedia terminal system, and relates to electronic equipment, wherein operation is convenient, the pickup effect is good, and poor anti-interference, severe distortion, long time delay of voice frequency and the like caused by remote sampling are avoided. The voice input method of the remote controller includes the steps that voice input by a user is received and converted into analog voice frequency signals; the analog voice frequency signals are converted into digital voice frequency signals; data compression is carried out on the digital voice frequency signals, and the digital voice frequency signals are converted into voice frequency compressed data; the voice frequency compressed data are sent to a multimedia terminal. The remote controller comprises pickup equipment, a master control unit and a communication unit, and the pickup equipment comprises a pickup module and an analog-digital conversion module. The multimedia terminal system comprises the multimedia terminal and the remote controller, and the multimedia terminal is provided with an adapter and is communicated with the remote controller through the adapter.

Description

technical field [0001] The invention relates to electronic equipment, in particular to a voice input method for a remote controller, a remote controller and a multimedia terminal system. Background technique [0002] Home multimedia terminal equipment such as TV, computer, etc., occupy an extremely important part of people's life. With the improvement of living standards, people not only put forward higher requirements for its quality, but also for the degree of intelligence and the friendliness of operation. [0003] In the application control of home multimedia terminal equipment (such as IPTV set-top boxes), sound input such as video calls, voice control, etc. is often involved, so it is necessary to connect sound pickup devices (such as microphones, etc.). The existing sound pickup equipment is generally built into the set-top box together with the camera or placed near the terminal display device (such as a TV). Using this method, the sound pickup effect is better withi...
