The disclosure presents a mining converged communication system. The system includes a first converged communication device and a plurality of service devices. The first converged communication device is configured to receive a first data packet from a first service device that initiates a service request in the plurality of service devices, determine a first target service device that receives the service request in the plurality of service devices, based on the first data packet, and send the first data packet to the first target service device. The first service device in the plurality of service devices includes any service device set on or under a mine, and the first target service device includes at least one service device set on and/or under the mine.

Mining converged communication system and communication method

A video encoding method includes: based on at least one of first distortion aware information about a current encoding unit and second distortion aware information about a corresponding reference encoding unit, determining a first predicted value of the current encoding unit using at least one interpolation filter, wherein the at least one type of interpolation filter may include an artificial intelligence (AI) interpolation filter; and encoding the current encoding unit based on the first predicted value of the current encoding unit.

Video encoding/decoding method, and corresponding devices

Apparatuses and methods of transmitting and receiving a speech signal. The method of transmitting a speech signal includes extracting low frequency feature information from an input speech signal by using a first feature extracting network; and transmitting a speech signal corresponding to the low frequency feature information to a receiving end. The method of receiving a speech signal includes receiving a first speech signal transmitted by a transmitting end; extracting low frequency feature information from the first speech signal and recovering high frequency feature information based on the low frequency feature information, by using a second feature extracting network; and outputting a second speech signal including the low frequency feature information and the high frequency feature information.
