Abstract: A circuit board structure includes a circuit substrate having opposing first and second sides, a redistribution structure disposed at the first side, and a dielectric structure disposed at the second side. The circuit substrate includes a first circuit layer disposed at the first side and a second circuit layer disposed at the second side. The redistribution structure is electrically coupled to the circuit substrate and includes a first leveling dielectric layer covering the first circuit layer, a first thin-film dielectric layer disposed on the first leveling dielectric layer and having a material different from the first leveling dielectric layer, and a first redistributive layer disposed on the first thin-film dielectric layer and penetrating through the first thin-film dielectric layer and the first leveling dielectric layer to be in contact with the first circuit layer. The dielectric structure includes a second leveling dielectric layer disposed below the second circuit layer.

Abstract: A video surveillance method and a video surveillance system applied the method are provided. The method includes capturing an image of at least a part of a monitored area to obtain a plurality of video streams; sensing the monitored area to obtain a plurality of sensing data; if an image of an object of a video stream is determined as a target object, determining whether the target object triggers a target event according to one of the sensing data corresponding to the video stream; if the target object is determined as triggering the target event, outputting a feature value corresponding to the target object according to a preset analysis condition, the video stream including the target object and the target event; and generating a notification event corresponding to the target object according to the feature value and a model weight value corresponding to the target object.

Abstract: The synchronous display streaming system for multi-view frames is provided. The server provides a plurality of display streamings of a content in a plurality of angles. The server stores accounts. The first electronic device logs in a relation account of the accounts of the server. The second electronic device logs in the relation account of the server. The first electronic device and the second electronic device are grouped in a synchronization operation group. The server provides the plurality of display streamings in the plurality of angles to the first and the second electronic device which log in the relation account respectively and display the frames of the content in the plurality of angles on the first and the second electronic device. Any electronic device of the synchronization operation group performs an operation on one of the electronic devices of the synchronization operation group through the relation account of the server.
