Abstract: Embodiments of the present disclosure provide an amplitude and phase calibration method and device, a storage medium, and an electronic device. The method includes: receiving a plurality of signals to be calibrated, with the plurality of signals to be calibrated being signals of one or more digital channels; routing the plurality of signals to be calibrated to a plurality of basic units, with each of the basic units configured to process one of the signals to be calibrated; and performing amplitude and phase calibration on the plurality of signals to be calibrated by the plurality of basic units.

Abstract: A method for knowledge representation and deduction of service logic includes: generating, based on a knowledge representation model, a semantic graph corresponding to conceptual-layer service logic, where the semantic graph includes one or more types of nodes and edges for connecting the one or more types of nodes, and the nodes include at least a node of a variable type; generating, based on the semantic graph and a physical table to which a service object is mapped, an instance graph, where the instance graph includes the nodes and edges in the semantic graph; generating executable code based on a service logic relationship between the nodes in the instance graph; and determining, based on the executable code and a data instance corresponding to a node whose in-degree is 0 in the instance graph, a data instance corresponding to each node in the instance graph.

Abstract: Disclosed are a method and electronic device for pushing reservation message, wherein the method includes: receiving a reservation request to subscribe to a live video sent by a first client terminal; determining a user reservation relationship according to the reservation request; after an event update notification of the live video is received, determining the user identification to which the reservation message is needed to be pushed, and determining a second client terminal to which the reservation message is needed to be pushed; and pushing a reservation message of the live video to the second client terminal. According to the method, a globally unique live broadcast video identification is set for the live video of each subsystem, and accordingly, a user may receive an alert message or a notification in real-time and synchronously on any terminal.

Abstract: Disclosed are a method and a device for realizing a custom menu based on a smart TV, including: receiving resource request information carrying a user ID sent by a client, wherein the resource request information is generated by the client according to a second trigger instruction of a user on an edit button in the custom menu; obtaining a channel list or an application list from a preset resource library according to the resource request information, and returning the channel list or the application list to the client; or sending the resource request information to a user center, thus allowing the user center to return a play record corresponding to the current user to the client according to the user ID.
