Description

Cross-platform audio and video adjustment device

This creation belongs to the field of video conferencing systems, especially for video signals of different operating platforms such as iOS, Android and Windows Mobile, and the resolution of the image signals of various multimedia playback devices, respectively, and can perform image signals. Cross-platform audio and video adjustment device for communication.

With the advancement of technology, such as the use of portable electronic devices such as smart phones, tablets, notebook computers or personal electronic notebooks (PDAs), it has become more and more popular, and it has become a must-have device for modern people. Or devices, and multimedia audio and video functions are also increasingly powerful, and thus are widely used in e-commerce, and can also be used in general conference systems or teaching systems.

At present, when the portable electronic device is applied to a conference system or a teaching system, the biggest problem arises in that the image signals used by various portable electronic devices vary depending on the operating system used. Different encoding methods can not make the image signal communicate. The operating systems currently appearing on smart phones and tablets, including Nokia's Symbian, Google's Android, Apple's iOS, RIM's Blackberry operating system, Microsoft's Windows Mobile 7, Linux, Palm/HP's WebOS, Samsung's Bada, Nokia's Maemo and MeeGo, among others, iOS, Android and Windows Mobile It is common, so there are different ways of encoding images.

With the rapid development of display panel technology, the size and resolution of these smart phones and tablet monitors have also grown rapidly, and the corresponding image resolutions that can be displayed will vary, in order to match various resolutions. The electronic screen system must be image scaling control for the resolution of the image source. For example, if the input image resolution is VGA mode (640x480) and the output demand is XGA mode (1024x768), the image resolution needs to be improved. If the input image resolution is SXGA mode (1280x1024) and the output demand is XGA mode (1024x768), the image resolution needs to be reduced to meet the specifications of the system application.

In summary, it is the main reason why the current cross-platform conference system or teaching system cannot be popularized. Therefore, most of the conference systems or teaching systems take a one-to-many approach and cannot be used for all kinds of portable electronic devices. The device is used for further applications.
