Abstract: According to one embodiment, an electronic apparatus includes a receiving module, a receiving module and a sound output module. The receiving module is configured to receive data of a motion picture and data of sound associated with a given timing in the motion picture, the data of the sound generated separately from the motion picture. The receiving module is configured to play back the motion picture. The sound output module is configured to output the sound at the given timing when the motion picture playing back module plays back the motion picture.

Abstract: A home network system includes a home network apparatus, and a recording reservation information-sending apparatus and recording/reproducing apparatuses which are connected to the home network apparatus. The home network apparatus has an interface circuit through which the auto-home network apparatus is connected to an Internet having a mail server and a recording reservation information-sending apparatus connected thereto, and a home network. The home network apparatus monitors recording reservation information sent to either of the recording/reproducing apparatus within a home network system, and instructs the recording/reproducing apparatus to perform the recording reservation, for example, if the recording/reproducing apparatus is in a wake-up state when being an object for recording reservation.

Abstract: This invention provides an on-vehicle electronic apparatus, which has a wireless communication unit which makes a wireless communication via a wireless LAN, means for acquiring position information and velocity information of vehicles before and after the self vehicle using the wireless communication unit, means for calculating the inter-vehicle distances between the self vehicle, and the vehicles before and after the self vehicle with reference to map information on the basis of the acquired position information and velocity information, and means for, when the calculated inter-vehicle distances are equal to or smaller than a predetermined distance and the velocities of the self vehicle and the vehicles before and after the self vehicle are equal to or higher than a predetermined velocity, taking a collision avoidance measure.

Abstract: A control apparatus controls first and second electronic devices. The control apparatus includes a unit which assigns first and second electronic mail addresses to the first and second electronic devices, respectively, a receiving unit which receives an electronic mail via a network, the electronic mail including one of the first and second electronic mail addresses as a destination address, a unit which selects an electronic device to be controlled from the first and second electronic devices in accordance with the destination address of the received electronic mail, and a unit which controls an operation of the selected electronic device in response to an instruction described in the received electronic mail.

Abstract: A DCM/FCM manager detects the coincidence of modules by comparing a device control module and a device function module transferred from a DCM/FCM memory of other device with a content in the inside of a DCM/FCM memory of its own device. One of coincident modules is deleted and this deletion is stored in the DCM/FCM memory. The DCM/FCM manager generates link information for making use of the deleted module and makes a registry store the link information. In case of controlling the other device, a control part reads out the module from the DCM/FCM memory based on the link information of the registry and generates a command based on the read-out module and transfers the command to the other device. Accordingly, the network equipment can control devices on the network with the least memory capacity.

Abstract: A wireless communication apparatus and a wireless network. A first wireless communication apparatus transmits a connection request to a second wireless communication apparatus. The first wireless communication apparatus transmits key information (Key K) to the second wireless communication apparatus through an electric power line or another cable. The first wireless communication apparatus also transmits a check signal to the second wireless communication apparatus. The second wireless communication apparatus answers the check signal. The first wireless communication apparatus acknowledges the connection request to the second wireless communication apparatus, and thereby data communication is performed.
