Abstract: A camera device includes an image data generation unit which generates image data corresponding to a captured image; a specific information generation unit which generates specific information relating to the image data; a recording unit which records the image data and the specific information on a removable recording medium which is removably attachable to the camera device; a reproducing unit which reproduces the image data and the specific information from the removable recording medium; an embedding unit which controllably embeds the reproduced specific information into the reproduced image data using a digital watermarking technique; and a control unit which controls the embedding unit to embed the reproduced specific information into the reproduced image data if a first process is selected by a user, and controls the embedding unit not to embed the reproduced specific information into the reproduced image data if a second process is selected by the user.

Abstract: Upon reproducing a TV program, it is a common practice to display video data sent from a broadcast station as it is, and the display pattern (layout) is not effectively changed (e.g., an object in video data is erased, or the object size is changed). A program ID from additional data contained in received TV information is detected, and when layout setting data corresponding to the detected program ID is stored in a memory, the corresponding layout setting data is read out from the memory to display program video data in the set layout. When a new layout is set, the user selects an object for which a layout is to be adjusted from objects that form image data in TV information, and adjusts movement, upscaling/downscaling, display ON/OFF of the selected object.

Abstract: An image processing apparatus for reproducing a recorded digital data stream can detect a time information or emergency news object contained in the recorded digital data stream, and inhibit display of the time information or emergency news which is insignificant in reproducing the recorded image. Alternatively, the image processing apparatus displays the object by an icon or the like. Alternatively, the image processing apparatus generates time information by a character generator on the basis of measured time information, replaces time information included in the recorded digital data by the time information generated by the character generator, and reproduces and displays the replaced time information.

Abstract: A method of screening a subject for mitochondrial dysfunction comprises detecting the presence or absence of single nucleotide changes in a hypervariable region of the mitochondrial DNA of said subject, the presence of such changes indicating that said subject is afflicted with or at risk of developing mitochondrial dysfunction.

Abstract: In a data communication apparatus for encoding information data by using a predetermined encoding method, encoded information data is transmitted isochronously with a predetermined communication cycle when the encoding method corresponds to a decoding method at an object node apparatus and non-encoded information data is transmitted asynchronously with the communication cycle when the encoding method does not correspond to the decoding method at the object node apparatus. It is therefore possible to perform an encoding process for the information data to be transmitted, in accordance with a decoding performance at the object node apparatus, to improve a communication efficiency, and to reduce a capacity of a memory used for communications.

Abstract: In a network for broadcast communication of digital information composed of image, audio etc., prior to the broadcasting of the digital information of which copying is limited, there is discriminated whether a recording device is present on the network and the output of the digital information is controlled according to the result of discrimination. If the recording device is present, the digital interface or the recording function of the recording device is so controlled that the broadcast digital information cannot be recorded. Thus, in case the digital information of which copying is limited is broadcast on the network, there can be prevented the unlawful copying or erroneous recording of such digital information.

Abstract: In a data communication apparatus for encoding information data by using a predetermined encoding method, encoded information data is transmitted isochronously with a predetermined communication cycle when the encoding method corresponds to a decoding method at an object node apparatus and non-encoded information data is transmitted asynchronously with the communication cycle when the encoding method does not correspond to the decoding method at the object node apparatus. It is therefore possible to perform an encoding process for the information data to be transmitted, in accordance with a decoding performance at the object node apparatus, to improve a communication efficiency, and to reduce a capacity of a memory used for communications.

Abstract: Upon implementing multi-functional TV broadcast and the like, it is desired to obtain information that pertains to a main image or that the user wants occasionally, if it does not pertain to the main image, in the form of an image as sub data with a small information size which is appended to the main image. For this purpose, MPEG4 data of sub TV information multiplexed in an MPEG2 datastream of the received and selected digital TV broadcast program is detected, and it is checked based on that detection result if MPEG4 data is included in the MPEG2 datastream. If MPEG4 data is included, an MPEG4 datastream is demultiplexed from the MPEG2 datastream, MPEG2 and MPEG4 data are respectively demultiplexed into sound, image, and system data, the demultiplexed data are decoded, and the output formats of MPEG2 image and sound data and MPEG4 scene and sound data are set.

Abstract: In a data communication apparatus provided with first and second digital interfaces respectively connectable to first and second external devices, communication (including synchronous communication and asynchronous communication) is conducted between the first external device and the first digital interface. When connection between the second digital interface and the second external device is detected, priority is given to communication with the second external device connected to the second digital interface. Preferably, the data communication apparatus causes the first external device to recognize the new connection configuration. As a result, the data communication apparatus can rapidly conduct data communication with a prescribed device without imposing a large load on the network.

Abstract: Disclosed are a data communication method whereby a first and a second node are directly connected so that they can exchange data directly, data communication apparatuses therefor, and a communication system that includes the apparatuses. A VTR and a printer are connected by an IEEE 1394 cable. When the printer requests the transmission of image data, the VTR transmits pertinent image data to the printer. Since the entry of a predetermined instruction at the operating unit of the VTR is inhibited during the transmission of image data, the occurrence of an obstacle to the transmission of image data can be prevented.
