Abstract: A method and apparatus for providing a customized interface in an ultrasound system is provided. The customized interface providing method includes: receiving a request for use of the ultrasound system from a user; displaying, in response to the request, a selection screen associated with selecting any one of software modes provided from the ultrasound system; receiving selection information from the user according to displaying of the selection screen; and executing a software mode corresponding to the selection information.

Abstract: Embodiments for ultrasound data processing in an ultrasound system are disclosed. In one embodiment, a mapping table, in which linear operation information is associated with a plurality of diagnostic modes, is stored in a storage unit. If there is an instruction to select at least one of the diagnostic modes, then an ultrasound data acquisition unit transmits/receives ultrasound signals to/from a target object to thereby acquire ultrasound data according to the selected diagnostic mode. A processing unit forms an ultrasound data matrix based on the ultrasound data and retrieves the linear operation information associated with the selected diagnostic mode from the mapping table to form linear operation matrices. Further, the processing unit performs a matrix operation of the ultrasound data matrix and the linear operation matrices.

Abstract: The present invention relates to an ultrasound diagnostic device. The ultrasound diagnostic device comprises a pair of transducers operable to transmit/receive ultrasound signals. The transducers are arranged to face each other. The transducers may be an array transducer including a plurality of elements, which are linearly arranged.

Abstract: Embodiments of the present invention may provide a digital beamforming apparatus in an ultrasound system having an array transducer, the apparatus comprising: a variable sampling clock generating unit to variably generate sampling clock signals based on reception delay times in ultrasound echo signals arriving at each element of the transducer elements of the array transducer, the variable sampling clock generating unit further being configured to output control signals corresponding to cycles of the sampling clock signals; sigma-delta analog-to-digital (A/D) converters connected to the respective transducer elements of the array transducer and being configured to convert analog signals outputted from the elements of the array transducer into digital signals in response to the sampling clock signals and the control signals; delay units to delay output signals of the sigma-delta A/D converters based on the reception delay time; and an adder for adding the delayed signals.

Abstract: A video signal recording and reproducing apparatus for a digital video cassette tape recorder by which it is possible to judge the transmission amount of the digital data inputted from a digital source, the type of the video tape, and whether or not the tape is recorded in accordance with the judgment result, for thus automatically controlling a recording mode and a reproducing mode, which includes a tape type detector for judging a tape type in accordance with a recordable wavelength of the video tape on which a digital signal is recorded; a data rate detector for detecting and judging a data transfer rate of a digital signal, and a controller for varying a recording or reproducing speed in accordance with the judged tape type and the data transfer rate of the digital signal.

Abstract: An improved video signal recording and reproducing apparatus for a digital video cassette tape recorder by which it is possible to divide, record and reproduce a digital video signal on a low density video tape into multiple tracks based on the amount of data recordable on one track of a high density video tape by controlling a recording/reproducing speed and a tape running speed in accordance with a judgement of the type of the video tape having a predetermined recordable wavelength. The apparatus includes a detector for detecting the type of the video tape in accordance with a recordable wavelength of the video tape, a judgement section for judging the type of the tape by receiving a detected tape type signal from the detector, and a controller for controlling a recording and reproducing speed in accordance with the judged tape type.

Abstract: An illegal view/copy protection method for a digital broadcasting system is disclosed including an audio/video signal transmission step for multiplexing and transmitting audio/video bit stream scrambled in control words and information where the control words and CPTC information for illegal view/copy protection are encrypted; and an audio/video reception step for decrypting the transmitted bit stream to analyze the CPTC information and control words, deciding whether recording is allowed or not to be recorded on cassette tape, and using the control words, performing descrambling and decoding to output audio/video signals to a monitor, thereby protecting copyright.
