Abstract: A system, apparatus, and method for notifying output information to a remote terminal in response to an input signal of a sound includes first and second memory blocks to store, respectively, characteristic data representing characteristics of various sounds, and various items of output information corresponding thereto such that each item of the output information is associated with each sound. An input device collects a sound to provide an input signal, an analyzer device extracts characteristic data therefrom, and a controller device operates according to the extracted characteristic data to identify the item of the output information corresponding to the collected sound, which is then transmitted to the remote terminal. A new sound and a corresponding item of output information can be registered for updating the first/second memory blocks. A plurality of input devices and a source detection device may also be employed in accordance with the invention.

Abstract: A two-dimensional spatial transformation system performs two-dimensional spatial transformation on an original video image in accordance with a two-pass method. Video data representing the original video image are input to a first video memory. Herein, a first pass transformation is performed on the original video image on the basis of transformation parameters used for a first pass, wherein the original video image is transformed to an intermediate video image with respect to a first direction (e.g., horizontal direction on a screen of a display). Video data representing the intermediate video image are transferred to a second video memory. A second pass transformation is performed on the intermediate video image on the basis of transformation parameters used for a second pass, wherein the intermediate video image is transformed to a transformed video image with respect to a second direction (e.g., vertical direction). The transformation parameters contain offset values and contraction rates.

Abstract: An automatic telerecording apparatus is comprised of a television antenna which receives a television signal, and a key view-designating block which designates as a key view a view appearing in an identical or similar pattern every time a television program desired to be recorded is broadcast, out of moving picture information based on the television signal received by the antenna. The designated key view is stored in a key view memory, and the moving picture information based on the received television signal is monitored, to detect the key view appearing in the moving picture information. When the key view is detected, the moving picture information is stored over a preset time period.

Abstract: In an image decoder of MPEG system or the like, a delay buffer which is able to store data which corresponds to at least one frame is provided in the rear stage of an input buffer which is normally provided, and a frame synchronizing pulse is applied to determine the timing of display independently of that which is determined by the bit stream. In synchronization with the frame synchronizing pulse which occurs for the first time after the passage of a delay period set for every frame in each of the bit streams, that frame is displayed. The input bit streams coming in during the period of time which elapses from the passage of the delay period until the occurrence of the frame synchronizing pulse, are absorbed by the delay buffer.

Abstract: An image decoder has a bus arbitrating circuit for controlling the use of the bus by any one of input bit stream buffer control circuit, decoding circuit, and image output control circuit. The bus arbitrating circuit controls the bus to provide the image output control means with the highest priority to use the bus without interruption to access the memory at predetermined time intervals. After the completion of the memory access by the image output control means, the bus arbitrating circuit detects whether a request for access to the memory is made by the input bit stream buffer control circuit, and when the request is made, permits the input bit stream buffer control circuit to use the bus. When both the image output control circuit and input bit stream buffer control circuit are not using the bus, permits the decoding means to use the bus to access the memory.

Abstract: An image decoder with a block image shifting device used for a movement compensating process in an image compression encoding/decoding system shifts image blocks each consisting of n.times.m pixels at a high speed in units of n pixels without using n to 1 selector circuits. When a movement compensation is carried out in each image block, a register stores a shift pixel number based on a movement vector. The image information read from a frame memory in units of n pixels is stored into a block buffer with selected bits masked by a mask pattern generating device in accordance with the shift pixel number to store unmasked bits into the block buffer. When reading the pixel data from the block buffer, the pixels are shifted according to a read address and the shift pixel number used to store the pixels into the block buffer. As a result, the output data from the block buffer is movement compensated without the use of the n to 1 selector circuits.
