Abstract

A television set having automatic volume control function and method therefore. The TV set includes: a communication interface for receiving an incoming call and a voltage change signal; a detecting unit for detecting the voltage change and output a corresponding volume control signal; and a volume control unit for adjusting the volume of the TV set according to the volume control signal. When the viewer receive a telephone call, a TV set connected to a telephone can lower the volume to a predetermined answering volume, when the viewer ring off the phone, the TV set can reinstate the volume of the TV set 30 to the pre-answering volume.

Claims

1. A television (TV) set, comprising:

a communication interface being connected with a telephone and a telephone network via a telephone line, for receiving an incoming call from the telephone network;

a detecting unit for detecting a voltage change of the telephone line via the communication interface and outputting a volume control signal, and

a volume control unit for adjusting a volume of the TV set according to the volume control signal.

2. The TV set as claimed in claim 1, wherein the detecting unit detects the voltage change of the telephone line from a high level to a low level, and outputs a first control signal for signaling the volume control unit to lower the volume of the TV set to a predetermined level.

3. The TV set as claimed in claim 1, wherein the detecting unit detects the voltage change from a low level to a high level, and outputs a second control signal to signaling the volume control unit to raise the volume of the TV set.

4. The TV set as claimed in claim 1, wherein the TV set further comprise a decoding unit connected to the communication interface for decoding a caller identification (ID) from the communication interface and outputting a decoded caller ID to the TV set, thus displaying the caller ID.

5. A method for automatically adjusting volume of a TV set, the method comprising the steps of:

determining whether a voltage level of the communication interface change or not, if the voltage level of the communication interface change, the TV set adjusts a broadcasting volume.

6. The method as claimed in claim 5, further comprising a step of receiving a user call identification (ID), processing and displaying the call ID.

7. The method as claimed in claim 5, further comprising a step of automatically lowering a broadcasting volume to a predetermined volume when the voltage level of the communication interface changes from a high level to a low level.

8. The method as claimed in claim 5, further comprising a step of automatically reinstating the broadcasting volume of the TV set when the voltage level of the communication interface change from the low level to the high level.

9. A television (TV) set, comprising:

a communication interface being connected with a telephone and a telephone network via a telephone line, for receiving an incoming call from the telephone network;

a detecting unit for detecting the voltage change of the telephone line from a high level to a low level, and outputting a first control signal, and

a volume control unit for lowering the volume of the TV set to a predetermined level upon receiving the first control signal.
