Abstract: The disclosure provides methods for transmitting and receiving video data, and a terminal device and a server. The server layers an original video into a plurality of video data streams, embeds extended information including feature information of a video data stream in a specified video data stream and transmits the plurality of video data streams to corresponding channels respectively for transmitting. A multicast prediction model in the terminal device may output a multicast access strategy based on the feature information of the video data stream and user experience information of the currently played video, and then a multicast combination currently accessed by the terminal device is adjusted based on the multicast access strategy to obtain a better multicast combination in the current network transmission environment, such that video data streams of corresponding quantities and quality are received. The above methods executed by the server and the terminal device can realize control of network congestion without increasing bandwidth consumption.

Abstract: A user terminal apparatus includes an alarm; a collector including one or more sensors configured to collect characteristic data of a target object; and a controller configured to obtain a terminal-side exception judgment result by inputting the characteristic data into a terminal-side exception diagnosis model, in response to the terminal-side exception judgment result indicating that the characteristic data is abnormal, transmit the characteristic data to a cloud server, receive diagnostic information from the cloud server, and based on the received diagnostic information, update at least one of a terminal-side multi-classification model or the terminal-side exception diagnosis model, or control the alarm to issue an alarm signal indicating that the characteristic data is abnormal.
