Abstract

After a television transmits an audio signal, which is generated by decoding an audio stream, to a mobile electronic device located within a detectable range of the television in a wireless manner, the mobile electronic device plays the audio signal received from the television for fulfilling surround sound performance.

Claims (23)

1. A video/audio playing method, applicable to a television having a signal transmission range, the method comprising:

transmitting an acknowledgement signal if a mobile electronic apparatus is within the signal transmission range;

transmitting an audio signal to the mobile electronic apparatus in response to receiving an approved signal returned from the mobile electronic apparatus corresponding to the acknowledgement signal such that the mobile electronic apparatus synchronically plays audio content of the audio signal; and

transmitting a layout setting signal indicating a deployment position of the mobile electronic apparatus in response to receiving the approved signal.

2. The method of claim 1 , wherein signal transmissions between the television and the mobile electronic apparatus is achieved by Wi-Fi network or wireless Internet.

3. The method of claim 1 , wherein the audio signal comprises audio content of at least one channel played by the television.

4. The method of claim 1 , further comprising:

receiving and decoding an audio signal stream in order to generate a decoded channel audio stream, which comprises a plurality of audio streams corresponding to a plurality of channel numbers, respectively.

5. The method of claim 4 , wherein receiving the approved signal returned from the mobile electronic apparatus further comprising:

retrieving an audio stream from the plurality of audio streams corresponding to the channel number specified by the mobile electronic apparatus contained in the approved signal and generating the audio signal according to the audio stream.

6. The method of claim 5 , wherein the audio signal comprises a sound channel of the audio stream corresponding to the specified channel number.

7. The method of claim 1 , wherein the approved signal comprises an identity of said mobile electronic apparatus.

8. A television having a signal transmission range, comprising:

a detecting module, configured to transmit an acknowledgement signal when a mobile electronic apparatus is within the signal transmission range and receiving an approved signal returned from the mobile electronic apparatus corresponding to the acknowledgement signal;

a wireless audio transmitter, configured to transmit an audio signal to the mobile electronic apparatus in response to receiving the approved signal such that the mobile electronic apparatus synchronically plays audio content of the audio signal; and

a layout setting module, configured for transmitting a layout setting signal indicating a deployment position of the mobile electronic apparatus in response to the detecting module receiving the approved signal.

9. The television of claim 8 , wherein signal transmissions between the television and the mobile electronic apparatus is achieved by Wi-Fi network or wireless Internet.

10. The television of claim 8 , the audio signal comprises the audio content of at least one channel played by the television.

11. The television of claim 8 , further comprising:

an audio decoder, configured for receiving and decoding an audio signal stream in order to generate a decoded channel audio stream, which comprises a plurality of audio streams corresponding to a plurality of channel numbers, respectively.

12. The television of claim 11 , wherein when the television receiving the approved signal returned from the mobile electronic apparatus, the wireless audio transmitter is further configured to retrieve an audio stream from the plurality of audio streams corresponding to the channel number specified by the mobile electronic apparatus contained in the approved signal and generating the audio signal according to the audio stream.

13. The television of claim 12 , wherein the audio signal comprises a sound channel of the audio stream corresponding to the specified channel number.

14. The television of claim 8 , wherein said approved signal comprises an identity of said mobile electronic apparatus.
