Appeal No. 2002-1231
Application No. 09/328,693
BACKGROUND
Appellants’ invention relates to a device for transmitting television pictures and
device for receiving said pictures. An understanding of the invention can be derived
from a reading of exemplary claim 1, which is reproduced below.
1. A device for transmitting television pictures, comprising:
means for dividing each television picture into blocks;
means for forming motion vectors for said blocks;
means for forming a reference vector and a plurality of difference
vectors from the motion vectors of a plurality of contiguous blocks which
form a sub-picture, the reference vector being the motion vector of any
selected one of said blocks, and each difference vector being the
difference between the motion vector of a block and the motion vector an
immediately adjacent block; and
a variable-length encoder for encoding the difference vectors into
code words of variable length, the motion vectors of a sub-picture being
applied to the variable-length encoder in the form of a series which
successively comprises the difference vectors and the reference vector,
the variable-length encoder being of a type which allocates a code word of
variable length to each sequence of zero values followed by a non-zero
value in said series.
