The invention relates to a picture playing method based on RCP (remote control protocol) communication. The method comprises the following steps of: (101) establishing and maintaining the RCP normal communication; (102) entering picture playing application and interface (103) sending a key remote control instruction by a remote controller; (104) receiving and transmitting the key information to a smart phone by a display apparatus; and (105) receiving, identifying and processing the key information by the smart phone as follows: playing the next picture if a right key is pressed down and the time threshold is not exceeded, forwards playing the pictures with a certain rate if the right key is pressed down and the time threshold is exceeded, playing the last picture if a left key is pressed down and the time threshold is not exceeded, backwards playing the pictures with a certain rate if the left key is pressed down and the time threshold is exceeded, forwards playing the pictures in a stepped form if an upper key is pressed down, and backwards playing the pictures in a stepped form when a lower key is pressed down.
Description
Technical field
The present invention relates to the control of mobile phone and multimedia, be specifically related to a kind of picture playing method based on the RCP communication.
Background technology
Traditional HDMI (High Definition Multimedia Interface; HDMI) has 19 pins; Wherein 12 pins mainly are the signals that is used for transmitting picture and audio frequency; Wherein these 12 pins are divided into 4 passages and come transmission of audio and picture, and we are referred to as transition minimized differential signaling (TMDS) to it; Also having 3 pins is to be used for doing control usefulness specially, and these control signals comprise DDC (Display Data Channel, DDC) and CEC (Consumer Electronics Control, consumer electronics control).Other pin is done other use so, so audio frequency, picture and control 15 pins that just accounted for only, this is the structure of traditional HDMI.
MHL (Mobile High-Definition Link, portable terminal high-definition audio and video standard interface) is the new interface that Silicon Image company is developed.It is different from 19 pins of traditional HDMI, and MHL has only 5 pins, and wherein 4 pins are used for transmission of audio and picture signal specially, and 1 pin is used for controlling specially.It equals to combine TMDS and DDC, CEC controls; It is a control bus; Had this control bus just can carry out omnibearing control to all audio frequency and picture, it becomes the transmission of storage and the data of data and is more prone to the benefit of MHL new interface that Here it is.At present, RCP (Remote Control protocol, Remote Device Control agreement), its effect is selection and the broadcast of controlling the mobile phone content through TV remote controller.But, in the process of existing selection and the broadcast of controlling picture of mobile telephone through TV remote controller, when especially picture is more, there is tangible complex operation, be inconvenient to locate problems such as picture and control picture broadcasting speed.
Summary of the invention
The technical issues that need to address of the present invention are, how a kind of picture playing method based on the RCP communication is provided, and can simplify the operation, improve the easy-to-use of interactive efficiency and user.
Above-mentioned technical problem of the present invention solves like this: make up a kind of picture playing method based on the RCP communication, be connected display device and smart mobile phone with cable through the MHL interface, specifically comprise following picture playing step:
