Error-correction encoding and decoding system

Abstract: The present invention provides an error-correction code encoding and decoding technique in which an information amount is variable in a block, and error-correction encoding in the block can be done efficiently without a substantial change in circuit configuration regardless of information amount. An encoder comprises a C1 encoding section for encoding an Ip information series, a C3 encoding section for encoding an Is information series, a control circuit for controlling the encoding sections based on an identification signal indicating whether the Is information series is contained, and a buffer memory. If an Is information series is contained, an area corresponding to the Is information series is deleted from check symbols of the Ip information series and replaced with coded data of the Is information series. A decoder decodes a received word thus encoded. This obviates superimposition-separation of C3 information, thereby realizing efficient error-correction encoding in a block, while maintaining an information amount of a block variable, without any change in circuit configuration based on information amount.

Three-dimensional wavelet-based scalable video compression

Abstract: A method of encoding an input video signal for communication over a computer network, the method comprising the steps of: i) applying a three-dimensional wavelet-based temporal and spatial decomposition to produce a plurality of spatio-temporal subbands; ii) quantizing the coefficients of the spatio-temporal subbands with a uniform scalar quantizer to produce a significance map; and iii) run-length and adaptive arithmetic coding of the signal by encoding the significance map, encoding the signs of all significant coefficients, and encoding the magnitudes of significant coefficients, in bit-plane order starting with the most significant bit-plane.

Multi-media window manager

Abstract: An apparatus and method for displaying non-obscured pixels in a multiple-media motion video environment (dynamic image management) possessing overlaid windows. In an encoding process, only boundary values and identification values corresponding to each window on a screen are saved in memory of a hardware device. In a decoding process, the hardware device utilizes these initial boundary values saved in memory in such a way that when incoming video data enters the hardware device, the hardware device need only compare the incoming video data's identification with the identification saved in memory. The hardware device includes: compare logic devices, counters, minimal memory devices, a control logic block, and a driver.

Image encoding method and apparatus

Abstract: This invention relates to an image encoding method and apparatus, and particularly has as its object to satisfactorily control the amount of encoded image data. In order to achieve this object, according to this invention, there is disclosed a technique for sequentially controlling the code amounts in accordance with accumulated code amount information and accumulated encoded area information, so that variable-length codes of an image fall within a predetermined memory capacity in a single pass. More specifically, in an image processing apparatus having a compression processor ( 15 ) for compressing input image information, and a memory ( 16 ) for storing encoded data by the compression processor ( 15 ), a code amount controller ( 14 ) calculates a reference code amount on the basis of the input image information, and controls the encoding condition of the compression processor ( 15 ) on the basis of the calculated reference code amount.
