A circuit, apparatus and method for efficiently and accurately calibrating an output driver current are provided in embodiments of the present invention. In an embodiment of the present invention, a circuit comprises a first digital-to-analog converter ("DAC") that generates a first current. A first transistor is coupled to the first DAC and generates a first biasing current responsive to the first current. A second DAC is coupled to the first transistor and generates a first control current res...

The invention is related to methods and apparatus that encode redundant motion vectors for predictive-coded visual object planes (P-VOPs) to increase the robustness of transmitted video signals. One embodiment provides the redundant motion vectors in a user data video packet of an MPEG-4 compliant bitstream, which thereby allows the enhanced bitstream to remain compliant with MPEG-4 syntax and backwards compatible with MPEG-4 decoders. The enhanced bitstreams allow a video decoder to display a v...

A method describes activity in a video sequence. The method measures intensity, direction, spatial, and temporal attributes in the video sequence, and the measured attributes are combined in a digital descriptor of the activity of the video sequence.

The invention concerns authentication to be performed in a telecommunications network, especially in an IP network. To allow a simple and smooth authentication of users of IP networks in a geographically large area, the IP network's terminal (TE1) uses a subscriber identity module (SIM) as used in a separate mobile communications system (MN), whereby a response may be determined from the challenge given to the identity module as input. The IP network also includes a special security server (SS),...

Aspects of the invention can provide a digital-to-analog converting circuit capable of, after converting digital data into an analog current, correcting the current value based on digital current correction data without any complex processing. The exemplary digital-to-analog converting circuit can include a first digital-to-analog converting circuit portion and a second digital-to-analog converting circuit portion. First digital data (image data) can input to the first digital-to-analog converti...

A digital-to-analog converter generates a monotonic sequence of reference voltages and selects an arbitrary pair of reference voltages, adjacent in the monotonic sequence. One of the selected reference voltages is supplied through a resistor and a switching device, connected in series, to the output terminal of the converter. The other selected reference voltage is supplied through another resistor and another switching device, connected in series, to the same output terminal. This arrangement s...

A semiconductor integrated circuit device has an analog signal conductor and a digital signal conductor formed on a single circuit board. In the lowest layer is laid a polysilicon conductor as the digital signal conductor, on top thereof is laid a first aluminum conductor as a shielding conductor, and further on top thereof is laid a second aluminum conductor as the analog signal conductor. With this structure, it is possible to give the highest priority to improving the transmission quality of ...

A video encoding/decoding system based on 3D wavelet decomposition and the human perceptual model is implemented. JND is applied in quantizer design to improve the subjective quality of compressed video. The 3D wavelet decomposition helps to remove spatial and temporal redundancy and provides scalability of video quality. In order to conceal the errors that may, occur under bad wireless channel conditions, a slicing method and a joint source channel coding scenario, that combines RCPC with CRC a...

An image processing apparatus in which a time base corrector and an image coding apparatus are integrated so as to use a common memory, thereby realizing a simple circuit arrangement. The apparatus performs control of writing each line of input image data to an image memory in turn while reading image data from the image memory in predetermined coding units, in the following manner: when a picture of the image data has been written, if the number of data units, each corresponding to the coding u...
