An information processing apparatus is disclosed which occupies a minimized space when it is not used. The information processing apparatus includes a stand including a base and a support arm extending uprightly from the base, a display unit supported for pivotal motion on the support arm, and a keyboard having a plurality of operation keys provided thereon. The support arm includes an upper arm portion and a lower arm portion. The upper arm portion has an upper pivotal fulcrum at an upper end portion thereof for supporting the display unit for pivotal motion, and the lower arm portion has a lower pivotal fulcrum provided at an upper end portion thereof for supporting the upper arm portion for pivotal motion. An accommodation space for accommodating the keyboard placed on the base is formed between the base of the stand and the display unit when the upper arm portion of the support arm is pivoted with respect to the lower arm portion and the display unit is pivoted with respect to the upper arm portion until the base is covered with the display unit.

Information processing apparatus

Input MPEG coded image data is input through a buffer to a variable length decoding unit where it is subject to variable length decoding. The quantized DCT coefficients are output to an inverse quantization unit, while the motion vectors are output to a motion compensation prediction unit. The quantized DCT coefficients are inversely quantized at the inverse quantization unit to generate DCT coefficients. The DCT coefficients have values of the items of frequencies higher than the desired frequency limit converted to 0 at the DCT coefficient conversion unit whereby the motion data found at the format conversion unit is added at the adder and the result input as the original image data to the format conversion unit. The pixels are thinned at the format conversion unit to generate a compressed image which is then displayed on a display unit.

Image decoding apparatus and process thereof and image reproduction

Disc-shaped recording medium, disc recording apparatus and disc

A method for processing the information of a still picture of high resolution displayed on a television screen is disclosed. The method includes the steps of receiving the picture information encoded by a pre-set encoding method, generating the averaging information specifying which interpolation is to be performed on the received picture information, decoding the picture information by a decoding method corresponding to the encoding method, storing the decoded picture information in a memory, reading out the stored picture information for processing the decoded picture information with interpolation, and outputting the interpolated picture information as a picture for display. An apparatus for carrying out the information processing method is also disclosed.

Optical recording medium with lists having playback control information

A picture reproducing apparatus includes a CD-ROM drive for fetching compressed video image data from a disc on which initial I-picture data for an initial picture for a menu display and a plurality of updating P-picture data for partially updating the initial picture are recorded. The picture reproducing apparatus also includes a RAN having a capacity of at least one video image frame and having an updating picture data storage area, an MPEG decoder for decoding MPEG encoded picture data and a CPU for initially transmitting the initial picture data and subsequently transmitting the updating picture data to the decoder. By making a picture display for displaying menu items or the like with the aid of a compressed picture decoder as used for displaying the compressed moving picture or still picture, the menu items or the like may be displayed without employing a graphic display circuit.

Video image updating and reproducing device with image selecting key

A decoding apparatus comprises detecting circuit for detecting a leading edge of a request signal which requests transmission of sequential data as digital signal, clock generator for generating a clock signal in response to an output signal from detecting circuits, and decoding circuit for decoding sequential data in accordance with the clock signal.

Decoding apparatus for digital signal

Two or more processors with differing address space sizes are used in a multi-processor system. A portion of the memory means accessible by the first processor with a larger address space size is also accessible by the second processor for elevating a utilization efficiency of the memory capacity. A window for the memory space of the second processor is provided in the address space of the first processor. The memory devices controlled by the second processor are controlled through this window by the first processor as well for elevating the utilization efficiency of the memory devices.
