Abstract: The embodiments of the disclosure provide a method for authentication and authorization and the authentication server. The disclosure provides a user management mechanism required by multiple applications, so each of the applications does not need to have its own user management mechanism. In this manner, the security mechanism can be provided by the authentication server to improve the security of the user data.

Abstract: The disclosure provides a network device, an image processing method, and a computer readable medium. The method includes: receiving a video stream from an IP camera; detecting whether a predetermined motion event occurs in the video stream according to a designated motion detection mode; in response to the predetermined motion event is detected, generating an event mark corresponding to the predetermined motion event and extracting a video clip corresponding to the predetermined motion event from the video stream; determining whether a video content satisfying a notification condition exists in the video clip; and in response to the video content satisfying the notification condition, sending the event mark and the video content to a smart device accessing the network device.

Abstract: The disclosure provides a method for authentication and authorization and an authentication server using the same method. The method includes: receiving login information from application; in response to authenticating the login information is valid, generating a user token and sending the user token to the application; receiving a request of the application for invoking an application programming interface (API), wherein the request includes the user token, an identity of the application, and a key of the application; in response to authenticating the user token, the identity, and the key are valid, generating an application token related to the application and sending the application token to the application to authorize the application to invoke the API.

Abstract: A controlling method for recording digital television programs is disclosed herein. The controlling method includes steps as follows. A service information packet is received from a digital television system terminal. The service information packet is valid within a time limitation and the service information packet includes an event information table corresponding to a plurality of program episodes. When one of the program episodes is assigned to be a first recording target and a predetermined recording period exceeds the time limitation, the service information packet is demodulated to obtain an event information section of the first recording target from the event information table. When the service information packet is updated, a matching procedure is performed on the event information section of the first recording target with the updated service information packet. A matched program episode is added into a scheduled recording target list automatically.
