Abstract

The invention relates to a handheld mobile device and method interactive with a projection apparatus. The handheld mobile device comprises a wireless connection module, a video input module, a storage module, a video decoding module, an audio processing module, an image processing module and a playing module, wherein, the video input module is used for receiving a video signal from the projection apparatus and storing the video signal in the storage module; the storage module is used for storing the video signal received from the projection apparatus; the video decoding module is used for decomposing the video signal in the storage module into an audio signal and an image signal; the audio processing module and the image processing module are used for audio-video-transcoding and compressing the audio signal and the image signal to form audio information and image information; and the playing module is used for playing the audio information and displaying the image information. By adopting the technical scheme, the playback content of the projection apparatus can be synchronously displayed on the handheld mobile device, a personalized slide display mode can be provided to a user, the user can conveniently make notes on a slide, and the content on the slide and the content marked by the user can be automatically stored on the handheld mobile device in different forms at any time.

Description

Technical field [0001] The technical field of projector control of the present invention particularly relates to a handheld mobile device interacting with a projector and a method for interacting with the projector. Background technique [0002] With the increasing application of projectors in education, business, government departments and other industries in recent years, users also have higher and higher requirements for the practical application and convenience of use of the projector. For example, they hope to combine the projector equipment with commonly used projectors. Hand-held mobile devices such as smart phones, PDAs, Pads, etc. are connected, so that when using the projector to play multimedia files (such as ppt files), the user can use the handheld mobile device to obtain the digital signal of the slide from the projector and display it on the handheld mobile device Synchronous display, and can save the content displayed on the handheld mobile device screen to the ha...
