Abstract

A control method for a video-audio playing system receiving a video-audio streaming signal is provided. The video-audio streaming signal includes at least a channel-program information. The control method comprises receiving a speech signal and analyzing the speech signal to obtain an acoustic feature of the speech signal. According to the acoustic feature, a speech recognition is performed to determine one of the channel-program information corresponds to the acoustic feature. According to the determined channel-program information, the video-audio playing system executes an operation corresponding to the channel-program information.

Claims

1. A control method for a video-audio playing system receiving a video-audio streaming signal, wherein the video-audio streaming signal includes at least a channel-program information, the method comprising:

obtaining a speech signal;

analyzing the speech signal to obtain an acoustic feature of the speech signal;

according to the acoustic feature, performing a speech recognition to determine one of the channel-program information corresponds to the acoustic feature; and

according to the determined channel-program information, the video-audio playing system executing an operation corresponding to the determined channel-program information.

2. The method of claim 1, wherein the operation includes the video-audio playing system is tuned from a first video-audio channel to which has been tuned to a second video-audio channel corresponding to the obtained channel-program information.

3. The method of claim 1, wherein the speech recognition further comprises a semantic analysis for obtaining an operating action corresponding to the speech signal so that the step that video-audio playing system executes the operation corresponding to the determined channel-program information further refers to the operating action.

4. The method of claim 3, wherein the operating action includes presetting a recording schedule, presetting a device turn-on schedule or pre-schedule a program delivering list.

5. The method of claim 3, wherein, according to the determined channel-program information and the operating action, the operation executed by the video-audio playing system includes presetting a recording schedule for recording a first video-audio program corresponding to the determined channel-program information, presetting a device turn-on schedule for automatically turning on the video-audio playing system to deliver the first video-audio program corresponding to the determined channel-program information at a predetermined time or automatically delivering the first video-audio program at a broadcasting time of the first video-audio program corresponding to the channel-program information.

6. The method of claim 1, wherein the channel-program information includes a plurality of video-audio channel information and a plurality of video-audio program information corresponding to each of the video-audio channel information.

7. A video-audio playing system, comprising:

a signal receiver, receiving a video-audio streaming signal, wherein the video-audio streaming signal includes at least a channel-program information;

an acoustic collecting apparatus, obtaining a speech signal;

a control system coupled to the acoustic collecting apparatus and the signal receiver, wherein the control system comprise;

a storage device storing a computer readable and writable program;

a processing unit executing a plurality of the instructions of the computer readable and writable program, wherein the instructions comprises;

analyzing the speech signal to obtain an acoustic feature of the speech signal;

according to the acoustic feature, performing a speech recognition to determine one of the channel-program information corresponds to the acoustic feature; and

according to the determined channel-program information, the video-audio playing system executing an operation corresponding to the determined channel-program information.

8. The video-audio playing system of claim 7, wherein the operation includes the video-audio playing system is tuned from a first video-audio channel to which has been tuned to a second video-audio channel corresponding to the obtained channel-program information.

9. The video-audio playing system of claim 7, wherein the speech recognition further comprises a semantic analysis for obtaining an operating action corresponding to the speech signal so that the step that video-audio playing system executes the operation corresponding to the determined channel-program information further refers to the operating action.

10. The video-audio playing system of claim 9, wherein the operating action includes presetting a recording schedule, presetting a device turn-on schedule or pre-schedule a program delivering list.

11. The video-audio playing system of claim 9, wherein, according to the determined channel-program information and the operating action, the operation executed by the video-audio playing system includes presetting a recording schedule for recording a first video-audio program corresponding to the determined channel-program information, presetting a device turn-on schedule for automatically turning on the video-audio playing system to deliver the first video-audio program corresponding to the determined channel-program information at a predetermined time or automatically delivering the first video-audio program at a broadcasting time of the first video-audio program corresponding to the channel-program information.

12. The video-audio playing system of claim 7, wherein the channel-program information includes a plurality of video-audio channel information and a plurality of video-audio program information corresponding to each of the video-audio channel information.

13. The video-audio playing system of claim 7, further comprising a display, wherein the signal receiver and the control system are configured on the display.

14. The video-audio playing system of claim 7, further comprising a display, wherein the control system is configured on a portable device and the signal receiver is configured on the display.

15. The video-audio playing system of claim 14, wherein the portable device receives at least a channel program list through a wireless transmission and the instruction of determining the channel-program information corresponding to the acoustic feature further refers to the channel program list and the channel-program information.
