Video Transfer Terminal Using Segmented Audio-Video Splitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video phones face limitations in display quality due to small screen size, camera pixel resolution, and inconvenient usage, requiring users to hold phones away from their ears and use earphones for video calls.
Innovation Solution
A terminal with an audio-video splitting/assembling unit, device discovering unit, and remotely waking-up unit that allows video stream transfer to a separate device with image capturing and displaying functions, enabling better display on a larger screen and using higher pixel resolution, while allowing convenient handheld phone usage without earphones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If video is displayed on the mobile phone screen, then the video call function is achieved, but the display effect is limited by the small screen size
Solution Approach 1:
The system is segmented into multiple functional components: the mobile phone handles audio processing and control, while a separate display device (such as a digital TV or computer monitor) handles video display. This segmentation allows the video to be displayed on a large screen without requiring the mobile phone itself to have a large display, thus resolving the contradiction between display area and device complexity.
Solution Approach 2:
The mobile phone acts as an intermediary device that captures video through its camera, processes audio, and transmits the video signal to an external display device. This intermediary approach enables the system to leverage the small mobile phone for portability and communication while offloading the large-screen display function to a separate device, thereby achieving both compactness and large display capability.
2Measurement precision
If the mobile phone camera is used for self-photographing, then the video call function is achieved, but the image quality is limited by the camera's pixel resolution
Solution Approach 1:
The mobile phone serves as an intermediary that captures video through its camera and transmits it to an external display device. This allows the system to use the mobile phone's camera for video capture while displaying the resulting images on a larger external screen, thereby improving perceived image quality without requiring the mobile phone camera itself to have high pixel resolution.
Solution Approach 2:
The video signal captured by the mobile phone camera is copied and transmitted to an external display device. This copying process allows the same video content to be displayed on a larger screen with better visual quality, effectively bypassing the limitation of the mobile phone's small display while maintaining the simplicity of using the existing mobile phone camera.
3Ease of operation
If the mobile phone is held far from the ears for video capture, then the camera can capture the face, but the usage manner is inconvenient and requires earphones
Solution Approach 1:
The mobile phone acts as an intermediary for audio processing while the external display device handles video output. This allows the user to hold the mobile phone in the conventional position near the ear for comfortable audio reception through the phone's speaker, while the video is displayed on a separate large screen, thereby achieving convenient usage without requiring earphones or changing the holding position.

AI summary
The present invention discloses a terminal for transferring video, comprising an audio-video splitting/assembling unit for assembling locally acquired video stream and audio stream, or splitting an audio-video assembly sent from a counter-terminal into video stream and audio stream; a device discovering unit responsible for searching for a first device with video capturing and displaying functions; wherein the audio-video splitting/assembling unit is adapted to receive a video stream of images captured by the first device after the device discovering unit has found the first device, and then to use the video stream for the local audio-video assembly, or the audio-video splitting/assembling unit is adapted to send the split video stream to the first device for video display. Obviously, since the counter-party's picture is transferred to the first device with a larger screen, the display effect is improved, and it is possible to bring the user a better visual experience without the limitation of the size of the video terminal screen. The present invention further provides a method for transferring video.
