Abstract: A method for scanning a local media file is provided. The method includes: receiving a scanning instruction, acquiring an identifier of a storage device, and creating a view table mapped to by a data table; scanning the storage device, so as to acquire path information about a media file in the storage device; comparing the path information about the media file with path information about a media file in the data table, so as to acquire path information about a media file that does not exist in the data table, and storing the same in the data table; and scanning a newly added media file according to path information about the newly added media file in the data table, so as to acquire file information about the media file, and updating a database by adding the acquired file information about the media file.

Abstract: A playing control method and a terminal are provided. The method includes the following. A playing control instruction carrying a device identifier of a playing device is acquired. A content input port and a power output port that are integrated in a control terminal and correspond to the device identifier are opened. Power output ports of the control terminal other than the power output port corresponding to the device identifier and a power output port coupled to a display terminal are closed, multimedia contents via the content input port corresponding to the device identifier are received, and the multimedia contents are transmitted to the display terminal for output and display.

Abstract: Disclosed are a remote control method for multi-terminal device, and a related apparatus and system. The method comprises: receiving, by a user terminal, a first switching instruction sent by a main remote controller via a forwarding device; responding to the first switching instruction, and displaying an identifier of a first slave remote controller pre-added to a remote controller list; and sending key value information about the first slave remote controller stored in a database to the main remote controller via the forwarding device, so that the main remote controller refreshes the key value information about the key layout of the main remote controller according to the key value information about the first slave remote controller, and performs a remote control operation on a terminal device corresponding to the first slave remote controller.

Abstract: Described is a remote control method of a multi-mode remote controller, comprising the following steps of: determining a current control mode, the remote controller comprising various control modes; obtaining a touch control signal of a user on a touch screen; and analyzing the touch control signal, generating a remote control instruction corresponding to the touch control signal under the current control mode, and sending the instruction to a user terminal, so that the user terminal operates currently displayed content. It is further provided a multi-mode remote controller, a user terminal and a system. Seamless automatic switching among multiple control modes in the remote controller with a touch screen can be realized, so as to meet various interaction requirements of different kinds of users.

Abstract: A method, a device and a system for light remote control positioning. Position coordinates of a light beam spot can be obtained by a light sensing film, so that remote control of interface elements can be realized. The method comprises the following steps: sensing, by means of a light sensing film covered on a display screen of a receiving terminal device, a light beam spot formed on the light sensing film by a light beam that is emitted by a transmitting terminal device (S101); and extracting position parameters of the light beam spot on the light sensing film, which are sensed by the light sensing film, and calculating out the position coordinates of the light beam spot based on the position parameters.
