Abstract

A smart playback method for TV programs includes: converting voice data to text data including a plurality of words; selecting a keyword from the words in the text data; providing a TV program according to the keyword; and controlling a screen to play the TV program.

Claims

1. A smart playback method for TV programs, comprising:

detecting whether a TV is turned on to obtain a detection result;

turning on the TV when said detection result indicates that the TV is not turned on;

detecting whether a user approaches by a proximity sensor;

turning on a microphone to obtain voice data when the step of detecting whether a user approaches indicates that a user is approaches;

converting the voice data to text data, wherein said text data comprise a plurality of words;

selecting a keyword from the words in the text data;

providing a TV program according to the keyword; and

controlling a screen to play the TV program.

2. The method according to claim 1, wherein the step of selecting the keyword from the words in the text data comprises:

selecting a plurality of candidate words from the words in the text data; and

selecting the keyword from the candidate words.

3. The method according to claim 2, wherein the step of selecting the keyword from the candidate words comprises:

selecting a word that matches a hot word in a hot word database from the candidate words as the keyword.

4. The method according to claim 3, further comprising:

generating a plurality of hot words according to hot messages on the Internet to form the hot word database.

5. The method according to claim 2, wherein the step of selecting the candidate words from the words in the text data comprises:

selecting nouns from the words in the text data as the candidate words.

6. The method according to claim 2, wherein the step of selecting the candidate words from the words in the text data comprises:

selecting the candidate words by removing functional words from the words in the text data.

7. The method according to claim 1, further comprising:

sending a notification associated with the TV program; and

receiving a playback confirmation corresponding to the notification;

wherein the step of controlling the screen to play the TV program comprises controlling the screen to play the TV program according to the playback confirmation.

14. The method according to claim 1, further comprising:

storing a history of times that a user watches the TV; and

turning on a microphone to obtain the voice data according to said history.

8. A control device for smart playback of TV programs, comprising:

a memory, storing at least one program; and

a processor, coupled to the memory, executing the at least one program stored in the memory to perform a method, the method comprising;

detecting whether a TV is turned on to obtain a detection result;

turning on the TV when said detection result indicates that the TV is not turned on;

detecting whether a user approaches by a proximity sensor;

turning on a microphone to obtain voice data when the step of detecting whether a user approaches indicates that a user is approaches;

converting the voice data to text data, the text data comprising a plurality of words;

selecting a keyword from the words in the text data;

providing a TV program according to the keyword; and

controlling a screen to play the TV program.

9. The device according to claim 8, wherein the step of selecting the keyword from the words in the text data comprises:

selecting a plurality of candidate words from the words in the text data; and

selecting the keyword from the candidate words.

10. The device according to claim 9, wherein the step of selecting the keyword from the candidate words comprises:

selecting a word that matches a hot word in a hot word database from the candidate words as the keyword.

11. The device according to claim 10, wherein the method performed by the processor further comprises:

generating a plurality of hot words according to hot messages on the Internet to form the hot word database.

12. The device according to claim 9, wherein the step of selecting the candidate words from the words in the text data comprises:

selecting nouns from the words in the text data as the candidate words.

13. The device according to claim 8, wherein the method performed by the processor further comprises:

sending a notification associated with the TV program; and

receiving a playback confirmation corresponding to the notification;

wherein the step of controlling the screen to play the TV program comprises controlling the screen to play the TV program according to the playback confirmation.
