An object of the present invention is to realize an in-home network system that is capable of smoothly controlling an appliance even when a new kind of appliance that has not been obtained conventionally is connected to an in-home network or even when an unusual, special use form is set in a network. A controller of the present invention compares a device type of an appliance connected to an in-home network with a skeleton stored in a skeleton DB. When a skeleton rule in accordance with the appliance type is not stored in the skeleton DB, a request for acquisition of the skeleton rule of the appliance is transmitted to a service agent. In addition, when the location of an appliance is moved, the controller sends a request for transmission of a new rule format to be added due to the movement to the service agent.

Controller, program product, and storage medium

A method is disclosed, for encoding a signal with a three dimensional image sequence using a series of left and right images. Each image in the left image series is a picture formed by non-interlaced or interlaced scanned left line images, and each image in the right image series is a picture formed by non-interlaced or interlaced scanned right line images. The left line images contained in the left picture are merged with the right line images contained in the right picture to produce an alternately arranged left and right line merged picture. The merged picture is encoded using an MPEG-2 compliant encoder.

Three-dimensional image coding by merger of left and right images

A method and apparatus for adaptively selecting a coding mode for video encoding systems using the techniques of predictive coding, interpolative coding, motion compensation, discrete cosine transformation (DCT), adaptive quantization, or variable length coding. In one system, a value related to an amount of total code, which is composed of current video code and its coding parameters for each of the above coding modes, is determined, respectively, and a coding mode corresponding to the smallest value is selected. Then, the encoding is performed using the selected coding mode.

A motion vector detecting circuit and a motion video compressing system are disclosed. The detecting circuit detect a vector which direct from a spatial location of a current macroblock to a spatial location of a reference macroblock. The detecting circuit includes a first extracting circuit, a second extracting circuit and a searching circuit. The first extracting circuit extracts upper bits from each pixel data of the current macroblock. The second extracting circuit extracts upper bits from each pixel data of the reference frame. The searching circuit searches the upper-bits-extracted reference frame for a macroblock having the strongest correlation with the current macroblock by comparing the upper-bits-extracted current macroblock with the upper-bits-extracted reference frame and outputs the spatial location of the reference macroblock. The motion video compressing system includes the motion vector detecting circuit, a transform-coding circuit, a subtracter, a comparator and a controller. The transform-coding circuit codes inputted data into compressed. The subtracter calculates a difference between each pixel data of the current macroblock and each corresponding pixel data of the reference macroblock directed by the motion vector. The comparator compares an amount of data being obtained by the transform-coding the current macroblock with an amount of data being obtained by the transform-coding the differential macroblock. The controller controls the transform-coding circuit such that the transform-coding circuit outputs which of the compressed current macroblock and the compressed differential macroblock has a smaller amount of data.
