Abstract: There are provided an air conditioner automatic control method, an air conditioner automatic control apparatus, a recording medium, and an air conditioner. The air conditioner automatic control method receives occupancy detection data indicating whether a user occupies a room, receives temperature data and humidity data indicating indoor temperature and humidity, predicts future occupancy probability information of the user by using the occupancy detection data, derives an optimal PMV by using the temperature data and the humidity data, and calculates an optimal temperature by using the optimal PMV, and controls the air conditioner based on the occupancy detection data, the future occupancy probability, and the optimal temperature. Accordingly, the air conditioner can be driven at the optimal temperature suitable for the user.

Abstract: An UPnP communication system and method for supporting an active standby mode is provided. A media system according to exemplary embodiments includes: a player configured to play back media in an active mode; and a processor configured to provide device information of the player to a controller in a standby mode, and activate the player when the controller requests playback of media. Accordingly, the fewest renderers excluding media playback are operated, so that media can be played back according to a request from the controller even when a media renderer enters a low-power mode.

Abstract: A method for operating multiple standby states and a broadcast receiving apparatus using the same are provided. The method for operating multiple standby states includes releasing, by a framework, a full wake lock for an electronic device, and acquiring, by the framework, a partial wake lock for the electronic device and entering a first standby state. Accordingly, a broadcast receiving apparatus based on an Android framework can operate multiple standby states which are designated by an application.

Abstract: A method for managing a broadcast receiving apparatus standby mode according to external signaling is provided. The method includes: generating a power management descriptor that a broadcast receiving apparatus refers to in order to perform a standby mode; and transmitting the generated power management descriptor to the broadcast receiving apparatus. Accordingly, since the broadcast receiving apparatus manages the standby mode more effectively, standby power consumed in the standby mode is further reduced and thus power saving effect can be achieved.

Abstract: A reverse-proxying method and a server/client system using the same are provided. The reverse-proxying method includes: providing, by a server, a service to a client; and, when the server enters a standby mode, providing, by a reverse-proxying server connected to the server, some services of the server on behalf of the server. Accordingly, the client receives the service without interruption and energy efficiency of the whole system is improved.
