Abstract: An IP address setting device includes a request packet transmitting unit, a response reception unit, an address information designation unit, and a setting packet transmission unit. The request packet transmitting unit transmits a request packet to a particular multicast address. The request packet requests transmission of an MAC address from each node of the network. The response reception unit receives responses from the nodes to the request packet transmitted by the request packet transmitting unit. Each response includes the MAC address of the corresponding node. Based on the responses received from the nodes by the response reception unit the address information designation unit designates a node to be set with address information including an IF address and designates the address information. The setting packet transmission unit transmits a setting packet to the particular multicast address.

With the special advance key depressed, the indicator is moved to the end of the data string when the indicator is positioned within the data string except at the end of the data string and to the end of the line when the indicator is outside the data string except at the end of the data string.

Abstract: In a predictive encoder for use particularly in a conference television system, a signal processing unit is used in producing a prediction signal and comprises three prediction circuits (22, 23, 31) and a selection circuit (24) coupled to the prediction circuits. The prediction circuits are for producing an inframe, an interframe, and a background prediction signals, respectively. Those signals are produced by processing an original signal at instants which precede a current instant and are different from one another. The selection circuit is for selecting one of the inframe, the interframe, and the background prediction signals. Therefore, it is possible to produce the prediction signal suitably predictive of the original signal. The signal processing circuit serves equally well in a predictive decoder.

The system includes a variable length encoder; a run-length encoder; a multiplexer for selecting as its output either the variable length code or the run-length code; a buffer memory for receiving and storing the output of the multiplexer, supplying it to a transmission line, and generating a signal indicative of the level of memory occupancy of the buffer memory; and control means for controlling the multiplexer so as to output only variable length code when the memory occupancy is below a first predetermined level. The control means further comprises an underflow signal generator for generating a signal indicative of when the memory occupancy is less than the first predetermined level.

Abstract: On subjecting a digital video signal representative of successive pictures to predictive coding by using correlation between two successive pictures, an estimated result is derived from the digital video signal to represent a degree of correlation between a current picture and a previous picture and is increased with a reduction of the degree. When the estimated result becomes greater than a predetermined threshold value as a result of a drastical change, such as a scene change, from the previous picture to the current picture, a control signal is produced. Furthermore, the digital video signal is separated into a preceding signal part ending at the previous picture and a succeeding part which begins at the current picture. The control signal controls the predictive coding so that the succeeding part be coded with an area of predictive coding of each picture gradually widened with time. The control signal may be supplied to a predictive coder.

Abstract: In a movement compensation predictive encoder, a vector detector (19) is supplied with a moving picture signal and produces a movement vector signal representative of at least one movement vector for each region of each frame. A picture analyzer (16) serves as a variation detector for detecting a variation in each region to produce a variation signal when the variation exceeds a predetermined threshold in one of the regions. The variation signal is used in giving a predetermined value, such as zero, to the above-mentioned at least one movement vector for that one of the regions. In place of the variation detector, a scene change detector can likewise be used to produce a scene change signal for giving a predetermined value to the movement vectors for a frame for which a scene change is detected.

Abstract: A video coding apparatus having a quantizer that is controlled by a quantization control signal. Stationary picture elements are coded such that quantization is coarse, which reduces the output information for the picture elements in the stationary image region and increases compression of the signal. The apparatus may include a calculation system for calculating a distance of a stationary picture element from the moving image region. The quantization is performed more coarsely as the calculated distance becomes longer. The quantizer may also be controlled such that coarse quantization is performed over a plurality of frames for the picture elements in the stationary region, and at a predetermined interval finer quantization is performed with respect to the same stationary picture elements, for further improving the picture.

Abstract: A motion-adaptive interpolation method for a motion video signal includes the steps of computing a representative motion vector of a moving object by using a certain number of motion vectors, and implementing a modification of the representative motion vector such that a variation of the representative motion vector at a present frame period with respect to the representative motion vector at a previous frame period is limited to a predetermined range, thus increasing the number of the frames per unit of time by using the modified representative motion vector. Further, a device for implementing the motion-adaptive interpolation includes motion estimation circuitry for evaluating an estimated motion of the motion video signal.

Abstract: An apparatus for discriminating a region that contains motion from a region that does not contain motion in a video signal, particularly for use in an inter-frame predictive coding apparatus. The apparatus bridges across different portions of a moving region or of a stationary region to avoid small isolated regions of either type that would cause spurious responses by the encoding circuit and a resulting degradation of picture quality. The apparatus determines for each picture element a frame difference, which is the brightness difference for that picture element from one frame to the next. The picture elements are divided into a predetermined plurality of blocks. Then a first evaluation value is produced by an adder (14, 14'), which may be alternatively the sum of the absolute values of the frame differences in each block, or the number of picture elements within each block for which the absolute value of the frame difference is greater than a predetermined threshold.
