the final rejection of claims 1-9. Claims 10-16 have been
canceled. Claims 17-23 stand allowed.
We affirm.
BACKGROUND
The disclosed invention relates to a method of encoding
moving images and decoding a coded moving image signal. In
particular, the invention relates to selecting a predictive
coding mode based upon an inter picture distance.
Claim 2 is reproduced below.
2. A moving image encoding method wherein the
difference between a moving image signal to be coded
and a predictive picture signal is calculated to
generate a residual signal, said residual signal is
orthogonal transformed to generate coefficient data,
and said coefficient data is quantized to generate
quantized data, wherein said predictive picture signal
is generated by applying motion compensation to locally
decoded quantized data, and wherein said quantized data
is variable length coded and transmitted to a
transmission line, said moving image encoding method,
[sic, no comma needed] comprising:
a first step of calculating a first inter picture
distance indicating a nominal distance between said
moving image signal and a past reference picture signal
which temporally precedes said moving image signal, and
a second inter picture distance indicating a nominal
distance between said moving image signal and a future
reference picture signal which temporally follows said
moving image signal; and
