Abstract: An in-vehicle infant-and-toddler monitoring method includes: shooting a child seat by a rear-seat infant-and-toddler monitoring apparatus to capture a video-and-audio signal; inputting the video-and-audio signal into an artificial intelligence engine, to analyze a video of the video-and-audio signal to detect a facial expression of an infant or a toddler, and to analyze an audio emotion of the infant or the toddler based on an audio feature, to generate a notification event corresponding to a current emotion of the infant or the toddler; sending the notification event by the rear-seat infant-and-toddler monitoring apparatus to a front-seat display apparatus; streaming and retrieving the video-and-audio signal by the front-seat display apparatus from a video-and-audio processing module based on the notification event to display the video-and-audio signal; notifying the rear-seat infant-and-toddler monitoring apparatus by the front-seat display apparatus based on the notification event to request a streaming vi

Abstract: The present invention discloses a method of bandwidth management, which is used in network transmission, including two main steps of setting a user-level bandwidth and setting an application-level bandwidth. At the first step of setting a user-level bandwidth, firstly, the method provides a IP address for the master user, and secondly, provides at least one IP address for the at least one slave user, and then assigns a primary bandwidth to the IP address for the master user and at least one secondary bandwidth to at least one slave user's IP address accordingly. At the second step of setting an application-level bandwidth, the method executes at least one Internet application, and assigns at least one application bandwidth to at least one Internet application accordingly. At least one Internet application is provided. The setting and assignment of the primary bandwidth and the secondary bandwidth mentioned above could be performed in Graphics Interface, which is friendly to users.
