Abstract

The present disclosure relates to a method and an apparatus for communication between a mobile phone and a TV set. The method comprises the following steps of: generating standard RGB signals by an LCD controller in a central processing unit (CPU) of the mobile phone; transmitting the RGB signals to an LCD of the mobile phone and a TV-OUT chip simultaneously; enabling the TV-OUT chip to receive and recognize the RGB signals through configuration of commands; carrying out video conversion on the RGB signals by the TV-OUT chip to output standard AV signals; and transmitting the AV signals to a display of the TV set via a dock. With this disclosure, information on the LCD screen of the mobile phone can be transmitted to the display of the TV set.

Claims

1. A method for communication between a mobile phone and a TV (television) set, comprising the following steps of:

step 11;

generating standard RGB signals by an LCD (liquid crystal display) controller in a central processing unit (CPU) of the mobile phone;

step 12;

transmitting the RGB signals to an LCD of the mobile phone and a TV-OUT chip simultaneously;

step 13;

enabling the TV-OUT chip to receive and recognize the RGB signals through configuration of commands;

step 14;

carrying out video conversion on the RGB signals by the TV-OUT chip to output standard AV signals; and

step 15;

transmitting the AV signals to a display of the TV set via a dock.

2. The method for communication between a mobile phone and a TV set of claim 1, wherein the step 14 further comprises:

step 141;

carrying out color processing and format conversion on the RGB signals by the TV-OUT chip; and

step 142;

converting the RGB signals into the standard AV signals by a digital-to-analog converter (DAC).

3. The method for communication between a mobile phone and a TV set of claim 1, wherein the commands in the step 13 are specific instructions in the corresponding chip specification.

4. The method for communication between a mobile phone and a TV set of claim 3, wherein the specific instructions include a width, a height, colorway and a frequency of an input/output image, whether the image is flipped by an angle, and a format of the output video.

5. An apparatus for communication between a mobile phone and a TV (television) set, comprising an LCD (liquid crystal display) of the mobile phone, a TV-OUT chip, an LCD controller for generating standard RGB signals, a 30-pin interface of the mobile phone, a dock and a TV set display, wherein the LCD controller is connected to the LCD of the mobile phone and the TV-OUT chip respectively, the TV-OUT chip is configured to receive the RGB signals, convert the RGB signals into standard AV signals and transmit the standard AV signals to the 30-pin interface of the mobile phone, the standard AV signals are transmitted to the dock via the 30-pin interface of the mobile phone and are then transmitted by the dock into the TV set for displaying on the TV set display.

6. The apparatus for communication between a mobile phone and a TV set of claim 5, wherein the LCD controller is integrated in a CPU (central processing unit) of the mobile phone.

7. The apparatus for communication between a mobile phone and a TV set of claim 5, wherein a command communication interface is further disposed between the TV-OUT chip and the CPU of the mobile phone to transmit an instruction for video conversion from the CPU of the mobile phone to the TV-OUT chip.

8. The apparatus for communication between a mobile phone and a TV set of claim 5, wherein the second pin in the 30-pin interface of the mobile phone is used for serial communication with software of the dock so as to accomplish data transmission/reception and functional operations.

9. The apparatus for communication between a mobile phone and a TV set of claim 5, wherein the dock connects to the TV set via an AV cable.
