5.13 Multi-Speed Forward (DVD, VCD)

Function : Playback occurs at the speed specified in the Speed Register
(Option - Auto Stop)
Format : (Address)MF (Multi-Speed Forward)
(Address)MR (Multi-Speed Reverse) (Address > 0)
Explanation : If the player is in Random Access mode when the command is
executed, the player enters Multi-Speed mode and returns the completed
status message immediately.
While in Multi-Speed mode, pictures are reproduced at the speed specified
by the Speed Register. No audio tracks are played during Multi-Speed
playback.
NOTE: These speeds are approximate values only.
If an address is specified, an Auto Stop occurs on the selected sequence.
The specified address is written as a Mark Frame or Mark Time and is
compared with the current address. If the current address matches the
specified address, the player enters Pause or Still mode and returns the
completed status message. This command functions in a similar manner as
the Stop Marker command.
If another command is issued before the player reaches the specified
Address, the Auto Stop command is canceled and the player enters normal
Multi-Speed mode. However, if the disc program does not allow a pause, the
player ignores the command.
NOTE: DVD offers 1, 1/2, 1/4, 1/8, 1/16, STEP1 speed reverse when REV
STEP/REV PLAY is set to FRAME on a ADV. SETUP menu or offers only
SLOW speed reverse in case it is set to VOBU.
VCD offers 1/2 to 1/16 speed forward only. Sometimes, depending on its
forward speed, VCD Multi-Speed Forward may finish several frames earlier
then the target address because playback does not rely on Frame counts.
