Abstract: A beam adjustment assembly includes a phase shifter and a connecting plate. The phase shifter includes a circuit board and main dielectric slabs configured to shift a phase. The circuit board is provided with a first strip and a second strip that are spaced. The first strip and the second strip are configured to respectively connect to radiating elements of an antenna. The connecting plate is slidably assembled on the circuit board and is configured to control an electrical connection between the first strip and the second strip. When sliding, the main dielectric slab can push the connecting plate to slide to control a quantity of radiating elements in the antenna system. The sliding of the main dielectric slab in the phase shifter is used as a driving mechanism of the connecting plate.

The first strip and the second strip are configured to respectively connect to radiating elements of an antenna. The connecting plate is slidably assembled on the circuit board and is configured to control an electrical connection between the first strip and the second strip. When sliding, the main dielectric slab can push the connecting plate to slide, to control a quantity of radiating elements in the antenna system. It can be learned from the foregoing description that, in this application, the sliding of the main dielectric slab in the phase shifter is used as a driving mechanism of the connecting plate.

Abstract: The present disclosure provides an operation instructing method and apparatus for a remote controller of an intelligent television, relating to the technical field of intelligent television. The method comprises: receiving an operation instruction from the remote controller; judging whether a user operation satisfies a preset instruction condition according to the operation instruction; and if so, displaying operation instruction information of the remote controller on a user operation interface, the operation instruction information being indicative of an operation of the remote controller. The present disclosure can solve the problem that since the service contents in the current intelligent television are numerous, and the operation mode varies with the service content, a misoperation will easily occur when certain service content is operated in a conventional operation mode, and the application of the service content is tedious and complex.

Abstract: The present disclosure provides a terminal device and a method for browsing service content of the terminal. The method comprises: classifying service contents in the terminal device into classes and assigning channel numbers to the classes in a reserved channel section; receiving a channel switching instruction inputted by a user, the channel switching instruction including channel number information of a target class to be switched; determining the target class corresponding to a channel number, according to the channel number information; transmitting service content in the target class to a display device for display. Thus the present disclosure can solve a problem in conventional terminal devices that are complicated to seek for service contents other than the live channel and are difficult to quickly switch to the service content of a needed application.

Abstract: The present disclosure provides an intelligent terminal-based tween interactive advertisement placement method and apparatus. The tween interactive advertisement placement method comprises: receiving advertisements issued by an advertisement management system through unidirectional DVB transport streams or bidirectional IP data streams; receiving a channel switching request input by a user; selecting an advertisement to be exhibited from the received advertisements according to a business rule; rendering the selected advertisement, and exhibiting the rendered advertisement on a screen. The present disclosure can improve the efficiency of the advertisement insertion when the intelligent terminal switches a channel, and solve the problem in the prior art that the advertisement exhibits a very small amount of information, and the user is easy to be averse to an advertisement that occurs at a fixed position for a long time.
