BVMRES
Reset command for block vector memory
- Channel switch (on switching to a new channel by remote control,
switch on BVMRES once and release; note: reset film mode detection
too [RESMOV])
- Freeze picture (on picture freeze switch on BVMRES and hold;
alternative: switch to non motion compensated scan rate conversion
[STOPMOM/ADOPMOM])
- SSC or MUP mode (on multipicture on double window/split screen
display switch on BVMRES and hold)
- Switch from SSC/MUP to SRC mode (switch to SRC mode, switch on
BVMRES, change master channel display size to full screen [768x576],
change back to normal master channel screen size and release
BVMRES)
- Vector memory reset takes place only on the active master channel
output size; to reset the whole vector memory switch to maximum
master channel size (768x576)
- Minimum hold time for BVMRES to have an effect: on CAMERA
MODE: 1 input field, on PAL FILM MODE: 2 input fields; on NTSC FILM
MODE 3 input fields

Penalty for periodic structures
Minimum vector length for null dbd penalty
Null vector reliability threshold, makes detection of null vector in
homogenous areas more reliable. Threshold value to adjust sensibility
of null vector reliability:
1111: insensible
:
0001: sensible to motion and noise
0000: off
MENULLPEN
4Fh
Additional penalty for null vector, if vector length exceeds length given
by MENPTH and dbd of null vector is greater as a given threshold, which
is defined by MENVRTH
