Video compression and transmission method and device, gateway and storage medium

Номер: CN116320465A
Принадлежит:

The invention discloses a video compression and transmission method and device, a gateway and a storage medium. The method comprises the following steps: acquiring a to-be-transmitted video, wherein the to-be-transmitted video is obtained by compressing an original video according to a video coding standard; enabling the to-be-transmitted video to pass through a random noise generator to obtain a noise-mixed video; according to the spatial position feature value, the time sequence feature value and the knowledge logic feature value, feature extraction and wavelet decomposition are carried out on the video after noise mixing, and a compressed video and a low-frequency detail sub-band, a wavelet horizontal detail sub-band, a vertical detail sub-band and a diagonal detail sub-band of each frame in the compressed video are obtained; establishing a loss function of the compressed video based on the error between the compressed video and the to-be-transmitted video; and adjusting the parameter ...

Method for judging terminal type for base station in rail transit scene

Номер: CN115967934A
Принадлежит:

The invention relates to the technical field of mobile communication, and discloses a method for a base station to judge a terminal type for a rail transit scene, and the method comprises the steps: sending a query request to an access terminal when the access of the terminal is detected, and receiving terminal capability information fed back by the access terminal according to the query request; matching the terminal capability information with data information in a preset terminal capability library; and determining a terminal type corresponding to the access terminal according to a matching result. According to the invention, the query request is sent to the accessed access terminal, the terminal capability information fed back by the access terminal according to the query request is matched with the data information in the preset terminal capability library, and then the terminal type of the access terminal is determined according to the matching result. Therefore, the technical problem ...
