The present disclosure relates to a method and a media device for pre-buffering media content streamed to the media device from a server system. The media device is connected to a network and has a rechargeable battery. The media device determines, by means of a bandwidth logic, an available network bandwidth and, by means of a charging logic, a charging level of the rechargeable battery. Based on these determinations, i.e. based on the determined available network bandwidth and the determined charging level of the rechargeable battery the media device selects a pre-buffering policy, by means of a pre-buffering logic, and pre-buffers media content, by means of the pre-buffering logic, from the server system in accordance with the selected pre-buffering policy.

A display device disclosed includes a liquid crystal panel (6), and an image optimization circuit (4) for switching, in accordance with an update frequency of image data, between (i) a first mode in which a liquid crystal driver (7) is driven at a first driving frequency and (ii) a second mode in which the liquid crystal driver (7) is driven at a second driving frequency lower than the first driving frequency. The display device can therefore be used even in a case where a transmission path for image data is limited and optimally display high-resolution image data with reduced electric power consumption.

A system includes a set-top box and a remote device. The remote device receives data representing an event from the set-top box. The remote device determines whether the event has occurred based on the data representing the event and generates a transition command to transition the set-top box from a first operating mode to a second operating mode. Further, the remote device transmits the transition command to the set-top box if the event has occurred.

A method of booting an electronic device, methods of operating and controlling an electronic device, an electronic device, a control terminal, and an electronic device control system. The method of booting the electronic device includes: displaying a first graphic code on a screen of the electronic device, each of the first graphic codes corresponding to a preset booting instruction; scanning, by a first control terminal, the first graphic code, and transmitting a booting request of the electronic device to a second control terminal according to the first graphic codes; generating, by the second control terminal, a booting command of the electronic device according to the booting request, and transmitting the booting command to the electronic device; determining, by the electronic device, a turning-on time length of the electronic device according to a matching result between the booting command and the preset booting instruction.

The embodiments of the present disclosure disclose a method and electronic device for controlling television energy efficiency, and a television. Wherein the method for controlling television energy efficiency includes: acquiring a cache address of frame data input by an external device from an application layer; searching for frame data corresponding to the cache address; extracting energy consumption parameter information from the frame data; and performing energy efficiency control for the television according to the energy consumption parameter information. In the technical solution of the present disclosure, the cache address of the frame data is acquired from the application layer, and the frame data corresponding to the cache address is searched for according to the cache address, so as to realize acquisition of the frame data input by the external device. Thus, the energy efficiency control is performed for the television according to information related to the frame data, so as to realize energy efficiency control for the television when the frame data is input by the external device.

A receiving apparatus includes a receiving unit that receives expected waves, and a control unit that sets the receiving unit to an operational state that has a lower electricity consumption within a range in which reception performance is allowed, depending on interference waves with respect to the expected waves that the receiving unit receives.

According to an embodiment, an electronic device is configured to output extended display identification data (EDID) to another electronic device, and to receive image data corresponding to the EDID from the other electronic device. The electronic device includes a memory and a controller. The memory is configured to store therein a plurality of distinct types of EDID. The controller is configured to detect a condition of a power source supplied to the electronic device, and to select an EDID corresponding to the condition.

A mobile device can be used to control a computing device different from the mobile device. The mobile device includes a processor configured to receive user input through a graphical user interface (GUI) of the mobile device. The processor can be configured to generate the GUI after detecting a magnetic field generated by a wireless power transmitter. The GUI includes a simulated button and/or an interface configured to receive tactile input indicative of spatial information. The processor is configured to provide information indicative of user input to the computing device to control the computing device.

The embodiments of the disclosure provide a method, device and storage medium for waking up a home interconnection device. The method can include: when the home interconnection device is in a state of standby, the home interconnection device receives a first beacon frame through a wireless access point (AP) of a Wireless Fidelity (WIFI) module of the home interconnection device; the home interconnection device searches a pre-set field of the first beacon frame for a waking-up identification; and when the pre-set field of the first beacon frame comprises the waking-up identification, the home interconnection device switches from the state of standby to the state of work.

A fiber optic-based communications network includes: a power insertion device, connected to multiple fiber links from a data source, configured to provide power insertion to a hybrid fiber/power cable connected to at least one fiber link of the multiple fiber links; the hybrid fiber/power cable, connecting the power insertion device to a connection interface device, configured to transmit data and power from the power insertion device to the connection interface device; and the connection interface device, configured to provide an interface for connection to an end device via a power over Ethernet (PoE)-compatible connection and to provide optical to electrical media conversion for data transmitted from the power insertion device to an end device via the hybrid fiber/power cable and the PoE-compatible connection.
