Application No. 08/860,537
controlling means inquiring about the reproduction speed, we find
Nagasawa’s disclosure in column 7, lines 11-22 which state that:
When the operator operates a certain reproduction pattern
designating operation key of the operation unit 28, commands
assigned to operation keys, e.g., various reproduction
commands, such as slow motion reproduction, quick motion
reproduction, etc., are supplied from the control unit 27 to
the storage device 22. When commands indicative of
reproducing at various reproduction speeds are supplied to
the output interface circuits 23-1, 23-2, ..., 23-k of the
storage device 22, the output interface circuits 23-1, 23-2,
..., 23-k of the storage device 22 output sources read from
the area Ar1 of the storage device 22 at speeds based on the
commands. [Emphasis added.]
The recorded video data from the storage area Ar1 is reproduced
at a designated reproduction speed that is based on the
reproduction commands supplied by input/output control means in
control unit 27. Therefore, as discussed above, Nagasawa teaches
“the controlling means ... inquires about the reproduction
speed,” as recited in claim 1, by disclosing a control unit that
controls the recording/reproducing of video data based on a
reproduction speed received from the control unit.
With respect to claim 2, we note that Nagasawa teaches that
audio/video data from storage area Ar1 is supplied through output
interface 23 to special effect mixer 25 at the normal transfer
rate (first data rate) in response to reproduction control signal
NPc (col. 5, lines 7-15). Furthermore, audio/video data from
storage area Ar2 is supplied through input interface 24 to high
