Inventor: WU ALLEN
IPC: H04N7/26
Filed: 1994-03-09
Abstract: Digital video signals are adaptively compressed for communication to a receiver.  Superblocks, each containing a plurality of blocks of digital video data, are compressed using PCM, DPCM with a general motion vector for the entire superblock, and DPCM with a specific motion vector for each block contained within a superblock.  The result of each compression mode is compared after accounting for overhead data, to determine which results in the least amount of data for each block.   These blocks are assembled into a superblock, and compared together with necessary overhead and motion vector data to the same superblock processed using all PCM as well as the superblock processed using all DPCM. The comparison determines which compression mode produces the least amount of data for the superblock.  The most compact superblock is selected for transmission.  The transmitted superblocks are decoded by a decoder that recovers the necessary motion vectors and overhead information which identifies the type of compression used to provide the superblock.

Inventor: ONO MASAHIKO
IPC: B65H37/00
Filed: 1992-10-01
Abstract: ABSTRACT OF THE DISCLOSURE    An instrument for transferring coating film onto a surface requiring transfer printing.  Conventional instruments of this kind for transferring coating film are not always easy to use because of such drawbacks as inflicting damage to a surface requiring transfer printing when tilting of the case is even slight.  An instrument of this invention for transferring coating film is in such a structure that: a transfer head is composed of a pressing body having a tape pressing surface roughly equal in width to the transfer tape and of a pair of right and left side plates in contact with the transfer tape for controlling widthwise movement of the transfer tape part which is in contact with said tape pressing body; the tape pressing surface of said tape pressing body and front edges of said side plates are adapted to be continuous or almost continuous in the direction of the width of tape; and each of front edges of said side plates is formed tapered so as to gradually depart from an imaginary straight line passing through the tape pressing surface toward outer sides in the width direction of the tape; whereby the instrument exhibits high transfer printing function and is easy to operate because no damage is inflicted to the surface requiring transfer printing even when the case tilts.  This invention is suitable for such cases as covering or erasing characters and pictorial images formed on a surface requiring transfer printing, such as recording paper, or, conversely, as readily forming characters or pictorial images on a surface.
