An internet protocol (IP) telephone device includes a plurality of IP modules and an IP-module selecting unit that selects an IP module based on a call command received from an opponent telephone terminal device.

IP telephone terminal device

A function processing unit includes a control-signal input/output unit to which a control signal indicating that radio data for a semiconductor device is transmitted is input by a cable signal, and a reset-signal input unit to which a reset signal instructing reset of the function processing unit is input by a cable signal, and when the reset signal is input, performs a reset process according to the reset signal. A radio-communication processing unit includes a radio-communication-processing-reset-signal input unit to which a radio communication processing reset signal instructing reset of the radio-communication processing unit is input by a cable signal, when the radio communication processing reset signal is input, performs a reset process according to the radio communication processing reset signal, and receives the radio data only when the control signal is input.

Semiconductor device

The portable image recording apparatus comprises a coding unit which codes an input sound and image data relating to an image, a parameter setting unit which variably sets a frame rate and a bit rate of coding to be executed by the coding unit according to a type of contents of the image; and a recording unit which records the coded data obtained by the coding unit into a small-sized recording medium.

Portable image recording apparatus

An internet communication system, which is provided with session managing serversand. In the system, each session managing server manages wireless communication apparatusesandand call relay serversand. For that reason, the processing load of each session managing server is allowed to be equalized. As a result, the operational efficiency of the system may be enhanced, and quality of services offered to the user of the system may be improved.

A duplicated part of identical images in an encoded image data master is judged to be selected. Image data to be reused is generated by adding a storage instruction to encoded image data of the duplicated part of the first identical image, and converting encoded image data of the duplicated part of the second identical image into a reuse instruction. In a reproduction process, decoded data in the encoded image data part including the storage instruction is stored in a vacant area and the decoded data is read at the point of the reuse instruction.

Image data reproduction method

Optimum relationship of data between local features, a coding data quantity, a quantity that expresses picture quality, and local coding parameters, for each block is stored. Extracted local features of one to a plurality of frames are stored. Setting of local coding parameters of each block included in one to a plurality of frames is adjusted so that the distribution of coding data quantity of each block in one to a plurality of frames is optimized within a predetermined range of data quantity based on the stored optimum relationship and local features.

In the motion picture data converter, an MPEG-2 decoding unit decodes motion picture data in an MPEG-2 format into motion picture data in an non-compressed format, a motion vector extraction unit extracts motion vector information from the motion picture data being decoded in said MPEG-2 decoding unit, a motion compensation unit generates the motion vector information in the MPEG-4 format, by causing the extracted motion vector information to be reflected in the motion compensation processing for the MPEG-4 format, and executes the motion compensation processing based on the motion vector information, and an MPEG-4 encoding unit encodes motion picture data in the MPEG-4 format, using the motion compensation processed data and the motion picture data in the non-compressed format.

Motion picture data converter, and computer product

In a moving picture coding control apparatus, optimum relationships between local features and local coding parameters that are necessary to optimize ranges of global coding parameters are stored, for each optimum range of global coding parameters capable of reproducing a moving picture that reflects characteristics of display units which display moving picture data and opinions from a plurality of users. Optimum local coding parameters are sequentially selected for global coding parameters and local features by using the store data. Moving picture data is coded based on the selected local coding parameters.
