A video processing method is provided. The video processing method includes: obtaining a sequence of video frames; obtaining an allocation parameter of the sequence of video frames, and allocating the sequence of video frames to at least one video processor according to the allocation parameter; and processing the allocated sequence of video frames by using the at least one video processor.

Video processing method and video processing apparatus

Disclosed are a method, device and system for sending a virtual card and a readable storage medium, which are configured to receive at least one audio-video stream data of a plurality of participant terminals in communication connection with a server side; determine target audio-video stream data corresponding to at least one speaker from the at least one audio-video stream data; obtain biological characteristic information for identifying the at least one speaker from the target audio-video stream data, the biological characteristic information includes face characteristic information and/or voiceprint characteristic information; generate a virtual card according to the biological characteristic information; overlay the virtual card to the target audio-video stream data, and synthesize the target audio-video stream data with other audio-video stream data in response to there being a plurality of audio-video stream data into a to-be-sent audio-video stream data; send the to-be-sent audio-video stream data to the participant terminals.

Method, device and system for sending virtual card, and readable storage medium

A video encoding apparatus includes a first processor and at least two encoders. The first processor is configured to divide a sequence of video frames into M first groups of pictures (GOPs) and send the M first GOPs to the at least two encoders, M being an integer greater than 1. The at least two encoders are configured to perform parallel encoding on the received M first GOPs to obtain M groups of video encoded data and send the M groups of video encoded data to the first processor. The first processor is further configured to merge the M groups of video encoded data into a video data stream.

Video encoding apparatus, video decoding apparatus, video playback system and method

A positioning control method includes: determining a position of a positioning object; determining, based on the position of the positioning object, at least one target positioning beacon whose distance to the positioning object satisfies a predetermined condition; and sending a prompt message to the target positioning beacon, wherein the prompt message is intended to instruct a positioning beacon to switch a broadcast frequency from a first frequency to a second frequency which is greater than the first frequency.

Positioning control method and device, positioning system and storage medium

The present disclosure provides a positioning method of a target node in a wireless ad hoc network, including: performing an initial positioning to obtain a first positioning result for the target node; determining, based on the first positioning result and a second positioning result for an other node in the wireless ad hoc network, whether a positioning error exists in the first positioning result or not, wherein the second positioning result at least contains an accurate second positioning result; and calculating a third positioning result for the target node based on the accurate second positioning result, in response to determining a positioning error exists in the first positioning result. The present disclosure further provides a positioning apparatus of a target node in a wireless ad hoc network, an electronic device, and a storage medium.

Positioning method and apparatus of target node in wireless ad hoc network, electronic device, and medium

A communication system, gateway, terminal, and communication method based on LoRa technology are provided. The system includes: a gateway configured to transmit an LoRa data packet containing a preamble, wherein duration of the transmission of the preamble is n; and a terminal configured to perform channel activity detection one time for a duration of qeach time after sleeping for a duration of p, continue to sleep for the duration of pin response to the preamble not being detected, or receive and process the data packet and then continue to sleep for the duration of pin response to the preamble being detected, wherein p&#x3e;q, and p+qis less than or equal to n.
