A display control method for generating and displaying composite images
A recently filed patent (Publication Number: US20230315371A1) describes a display control method that allows for the seamless integration of multiple video sources on a display device. The method involves receiving a first video signal from a first video source device and displaying the corresponding images on the display device. While the first images are being displayed, a connection is established with a second video source device, and a second video signal is received through this connection. The method then generates composite images by combining the first images with the second images, without requiring any user input. These composite images are then displayed on the display device.
The patent also outlines different ways in which the first video signal can be received. It can be received through a wired connection, such as a High Definition Multimedia Interface (HDMI) or a DisplayPort (DP) connection. Alternatively, it can be received through a wireless connection based on protocols like Airplay or Miracast.
The method also includes establishing a connection with the second video source device. This connection can be established using near-field communication, allowing for a wireless connection between the devices.
Each composite image generated by the method consists of at least a first region and a second region. The first region includes one of the first images, while the second region includes one of the second images.
The patent also describes a display control apparatus that can be used in conjunction with a display device. This apparatus includes a processing circuit that receives the first video signal and allows for the display of the first images. It can also establish a connection with a second video source device and receive the corresponding second video signal. The processing circuit then generates composite images based on the first and second images, enabling the display device to show these composite images.
The display control apparatus can have a video transmission interface circuit for receiving both the first and second video signals through wired connections, such as HDMI or DP. It can also have a network interface circuit for receiving the video signals through wireless connections based on protocols like Airplay or Miracast.
Additionally, the display control apparatus can include a near-field communication interface circuit for establishing a wireless connection with the second video source device.
Finally, the patent describes a display device that includes a display module and a display control apparatus. The display control apparatus, similar to the one mentioned earlier, allows for the display of composite images by receiving and processing video signals from multiple sources.
In summary, this patent outlines a display control method and apparatus that enable the seamless integration of multiple video sources on a display device. It allows for the generation and display of composite images without requiring any user input, providing a convenient and efficient way to view content from different sources simultaneously.
