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.

On-vehicle electronic apparatus

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.

Network equipment and networking method

A supplemental information embedding apparatus having a device for capturing image data, a first memory for storing image data indicating the presence of copyright protection, a first encoder for encoding the image data obtained by the image capturing means to a first format digital image data by n stages of processing (n is a positive integer greater than or equal to 2), a second memory for storing the first format digital image data produced in the digital image data producing means, a second encoder for encoding the image data indicating the copyright data supplied from the image capturing device or the first memory to a second format digital watermark by i stages of processing (i is a positive integer less than n), a third memory for storing the second format digital watermark encoded by the second encoder, a decoder for decoding the first format digital image data stored in the second memory up to a desirable stage of decoding, a divider for dividing the second format digital watermark stored in the third memory into predetermined format blocks, an embedder for dispersively embedding the blocks of the digital watermark into the image data encoded up to i stage by the first encoder or the irate data decoded up to i stage by the decoder, a third encoder for encoding the image data obtained by the embedder by exerting operations on and after j stage (j&equals;n&minus;1) of encoding so as to produce the first format digital image data, and a fourth memory for storing the first format digital image data encoded by the third encoder.
