example 1

[0078] When the user checks a certain photo in the mobile phone through the mobile phone 20 at home, and wants to share the photo to the smart TV at home for viewing, then find "share" in the preset menu of the mobile phone 20 and trigger it, and then choose to share to "Smart TV" (see figure 2 shown).

[0079]After the mobile phone 20 receives the above operation, it is judged whether the display interface 21 of the mobile phone is a static interface or a dynamic interface. Since the application corresponding to the interface of the viewed photo is "album", then according to the attributes of the album, it can be known that the display interface 21 of the mobile phone is a static interface or a dynamic interface. If the display interface is a static interface, the image data of the display interface only needs to be acquired once.

[0080] The first WiHD chip sends a connection establishment request to the second WiHD chip, and when the smart TV accepts the connection reque...

[0083] When the user watches a certain video file on the mobile phone at home and wants to share the video file to the smart TV at home for viewing, then find "Share" in the preset menu of the mobile phone and trigger it, and then choose to share to "Smart TV".

[0084] When the mobile phone receives the above operations, it will determine whether the display interface is a static interface or a dynamic interface. Since the application corresponding to the interface for watching videos is "Baofengyingyin", the display when watching videos can be known according to the attributes of "Baofengyingyin". If the interface is a dynamic interface, it is necessary to obtain the image data of the display interface in real time.

[0085] According to the application (Baofengyingyin) corresponding to the display interface determined in the above steps, find the file corresponding to the display interface in the application (for example, "The First Episode of Zhen Huan Biography"), and the...

Abstract

The invention provides a one screen sharing method, an apparatus and a system. A multimedia equipment sending end and a multimedia equipment receiving end are included. The sending end comprises a first wireless high definition chip possessing an emission function. The receiving end comprises a second wireless high definition chip possessing a receiving function. On a multimedia equipment sending end side, the method comprises the following steps of acquiring image data of a display interface when an instruction that a display interface of the multimedia equipment sending end is shared to the multimedia equipment receiving end is received; through the first wireless high definition chip, sending a request of connection establishing to the second wireless high definition chip so as to establish communication connection between the two ends based on the wireless high definition chips; through the communication connection, sending the image data to the multimedia equipment receiving end so as to realize one screen sharing between the two ends. By using the one screen sharing method, the apparatus and the system, a one screen sharing application does not need to be preset; an operation process is simple and data transmission has no time delay; and a user watching experience can be greatly improved.

Description

technical field [0001] The present invention relates to the field of multimedia technology, in particular, to a method, device and system for sharing the same screen. Background technique [0002] With the popularity of multimedia devices such as smartphones, tablet computers, and smart TVs in modern families, the same-screen sharing technology is being used more and more. The existing same-screen sharing technology is to firstly connect the sending end of the multimedia device with the receiving end of the multimedia device through a WIFI (Wireless Fidelity) network, and connect the multimedia device to the same-screen sharing application (such as AirPlayer, WirelessDisplay, etc.) After the audio, video, picture and other multimedia data selected in the sending end are compressed and modulated, they are sent to the receiving end of the multimedia device supporting the same-screen sharing application through the WIFI network. After receiving the multimedia data, the receivin...
