DEVICE AND METHOD FOR TRANSMITTING VIDEO - A simplified explanation of the abstract
This abstract first appeared for US patent application 17900243 titled 'DEVICE AND METHOD FOR TRANSMITTING VIDEO
Simplified Explanation
Abstract
The patent application describes a video transmittance device and method that can adapt to changes in network bandwidth by adjusting the resolution or frame rate of a video signal. This is done based on a dual-bandwidth threshold and a network bandwidth prediction value received from a video reception device. The device receives a video signal, sets a dual-bandwidth threshold, determines a network bandwidth prediction value, decides whether to change the resolution or frame rate of the video, updates frame sequence information, sets an encoding parameter, encodes the video signal, and transmits it to the video reception device.
Bullet Points
- Video transmittance device and method for adapting to network bandwidth changes
- Adjusts video resolution or frame rate based on a dual-bandwidth threshold and network bandwidth prediction value
- Receives video signal, sets dual-bandwidth threshold, and determines network bandwidth prediction value
- Decides whether to change video resolution or frame rate based on the threshold and prediction value
- Updates frame sequence information and sets encoding parameter accordingly
- Encodes and transmits the video signal to the video reception device

Original Abstract Submitted
Various embodiments of the disclosure relate to a video transmittance device and method capable of robust response to network bandwidth changes by changing the resolution or frame rate of a video based on a dual-bandwidth threshold which is a reference value for determining whether to change the resolution or frame rate of a video signal and a network bandwidth prediction value determined based on predetermined control information received from a video reception device. The video transmission device may include: receiving a video signal, setting a dual-bandwidth threshold which is a reference value for determining whether to change a resolution or a frame rate of the video signal, determining a network bandwidth prediction value based on specified control information received from a video reception device, determining whether to change the resolution or frame rate of the video based on the network bandwidth prediction value and the dual-bandwidth threshold, updating frame sequence information based on the resolution or frame rate being changed, setting an encoding parameter based on the changed resolution or frame rate, encoding the video signal based on the set encoding parameter, and transmitting the encoded video signal to the video reception device.
