摘要： An ultrasonic imaging system can include an ultrasound imaging probe, a computing device, and a link for communicatively coupling the computing device and the ultrasound imaging probe. The probe can include an ultrasonic transducer and preprocessing circuitry. The ultrasonic transducer can produce an electrical signal from an ultrasonic pressure wave and have a transducer element. The preprocessing circuitry can be electrically coupled to the ultrasonic transducer and have a signal converter and a signal integrator. The signal converter can condition a signal from the transducer element and convert the signal to a digital signal. The signal integrator can combine the digital signal into a transmission signal with at least a 10 Gigabit per second data rate. The signal can then be transmitted for processing by the computing device.

摘要： According to one embodiment of the present invention, a video information encoding method comprises: a step of predicting information of the current coding unit to generate prediction information; and a step of determining whether the information of the current coding unit coincides with the prediction information. If the information of the current coding unit coincides with the prediction information, a flag indicating that the information of the current coding unit coincides with the prediction information is encoded and transmitted. If the information of the current coding unit does not coincide with the prediction information, a flag indicating that the information of the current coding unit does not coincide with the prediction information is encoded and transmitted and the information of the current coding unit is encoded and transmitted. In the step of generating prediction information, the prediction information may be generated using the information on the coding unit adjacent to the current coding unit.
