A computer-implemented method includes receiving, at a microphone of a voice-controlled device, a speech input, generating an electrical signal having a first gain level that is below a gain threshold for audible detection by a user, transmitting the electrical signal to the speaker and detecting, by the microphone, an audio signal that includes a combination of ambient noise and a probe audio signal, wherein the probe audio signal is output by the speaker based on the electrical signal. The method further includes determining a power level of the probe audio signal and determining a state of the display based on the power level of the probe audio signal.

A signal adjusting device and method, and a test equipment. The signal adjusting device includes: a level controller, a level circuit, a comparison circuit and a selecting circuit. The level circuit is electrically connected with the selecting circuit; the level controller is configured to perform a level adjustment to a first signal, so as to generate a level signal, and the generated level signal is outputted by the level circuit; the comparison circuit is configured to: determine that the level signal meets a preset condition, and generate and output a corresponding feedback signal to the selecting circuit, in response to determining that the level signal satisfies the preset condition; and the selecting circuit is configured to output, as an adjusted signal, the level signal corresponding to the feedback signal.

A method of testing a managed networked video-delivery devices or delivery devices at a base location consists of the following steps. A customer disconnection notice is issued to a service provider resulted in a disconnection event/state of the delivery device. A series of tests are conducted on the delivery device at the customer location. Reprogramming and resetting operations are carried out on the delivery device simultaneously with the disconnection event/state occurring at the service provider prior to retrieval of the device from the customer location, to prepare the delivery device for future use prior to receipt thereof by the service provider.

An application framework includes user interface components and TV resources which facilitate development of intelligent TV applications, including third-party applications. These components and resources are complimented by one or more data services that can generally be run at a services level, to provide access to a variety of data, such as media and program metadata for one or more of local or remote sources. These data services can reside in one and more libraries within the software system components and modules. The various third-party apps are further supported by a third-party application support module, in conjunction with an app center application that supports various different views of the installed apps: a master view, a collection view, and a detail view.

The disclosure provides a display device and a display image rotation adapting method. A rotating component may be controlled to rotate a screen into a portrait mode if a video media resource is a vertical media resource and the screen is in a landscape mode; or, the rotating component may be controlled to rotate the screen into a landscape mode if the video media resource is a horizontal media resource and the screen is in a portrait mode, so as to adapt to an aspect ratio corresponding to the video media resource.
