MV720p-HD HDMI Video player with SYNC

FRONT VIEW:

Power switch:

Switch to ON position to power the MV720p-HD. When using USB drive, bootup time is 35 seconds.

When using the (optional) internal SATA Hard Drive, bootup time is 25 seconds.

Mini USB port:

Use this port to access the internal Hard Drive only. Use Mini USB to Std USB cable. Connect to PC’s

USB port and turn MV720p-HD power on. PC will see the MV720p-HD and assign a letter hard drive.

Use it to format the hard drive (NTFS format) and to copy and delete files in the Hard Drive.

SATA socket (built in internal socket only, no hard drive):

The MV720p-HD has a built in SATA socket for 2.5” laptop SATA hard drive, 5400 or 7200 rpm. The

SATA hard drive is not included. For new hard drive only, format it using NTFS before use. For heavy

duty application, use Solid State SATA hard drive.

CAUTION:

Due to heat generated by the internal SATA laptop hard drive, place the MV720p-HD in an air

conditioned and well ventilated area. If possible, use solid state hard drive to minimize the heat.

Remote:

IR receiver for IR remote control. Use the IR remote control (“SEARCH” key) to adjust the resolution

output (from 480p to 1080i) and to test the input and adjust the MV720p-HD setting in manual mode.

Use the IR remote control to set the IR mode and auto time delay.

LED indicator:

RED LED indicates power is ON.

GREEN LED blinks only when using Hard disk. When using USB drive or playing from network, green

LED is OFF.

REAR VIEW:

Digital Input: (see description below)

Built in digital input. Connect 3 single pole push buttons OR 3 single contact + 3 double contact for a

total of 6 push buttons.

To trigger the input, short it momentarily to ground.

Input 1 plays line 01=xx in the autoplay.txt etc. For more info, see digital input section below.

A/V port, Composite and audio out:

For Audio use a regular stereo mini jack to 2 RCA cable adapter.

NOTE: Audio is always ON at all video setting. For Closed Caption set player to NTSC or 480p.

For composite video PLUS stereo audio use triple mini jack to 3 RCA cable adapter. The triple mini jack

is included with the unit. A regular Ipod triple mini jack will not work because the metal plug is too short.

Output is composite video and 2 RCA audio line out. While booting up, the output is at 576p. You need a

monitor that can automatically switch between PAL/NTSC. If you are using NTSC monitor, you will not

see anything during booting up.

NOTE: Composite video out is available only when the MV720p output is set at 480p, NTSC or

576p(PAL). At 720p or 1080I, the composite (CVBS) output is not available (out of range), but the stereo

audio is still ON.

Use SEARCH key of the IR remote to toggle the video resolution.

YPbPr component video out:

This output is always on at all video setting. Use triple mini jack to 3 RCA cable adapter available from

Akman Inc.

A regular Ipod triple mini jack will not work because the metal plug is too short.

Audio for YPbPr is available on the A/V port. Use a standard stereo mini jack to 2 RCA.

Use SEARCH key of the IR remote to toggle the video resolution.

HDMI out:

This output is always on at all video setting. Use HDMI cable to connect into the HDMI input of the

LCD TV monitor. HDMI cable carries the digital Audio and Video signal.

USING DVI (with HDCP):

Use HDMI to DVI cable converter to connect directly into the DVI input.

DVI INPUT CAUTION:

There are 2 types of DVI input. The older LCD projectors and PC Monitors have regular DVI input. This

input does not decode HDCP. MV720p-HD HDMI output will not work with this DVI input. We can

provide you with the DVI software that will enable you to use this older DVI input.

The new LCD projectors and PC Monitors have DVI input with HDCP. Look at the DVI input of

monitor’s specification. The DVI input should read DVI(HDCP). The MV720p-HD HDMI output will

work fine with this DVI(HDCP) input.

Use SEARCH key of the IR remote to toggle the video resolution.

USB2.0 port:

Connect to USB Flash drive (thumb drive, Stick drive) and any other memory storage that use USB2.0

interface such as External Hard Drive (passport), Memory card reader etc.

LAN port:

Connect into the hub of the local area network using Cat5 cable.

Currently you can only connect to the network from manual mode.

RS485 port:

Connect into IN6 board using RJ12 cable. You can connect up to 4 IN16 board, total 48 digital input.

This port is also used to sync MV720p’s using the IN6 and Sync board.

SPDIF digital audio out:

Digital audio out using TOSLINK fiber optic cable. Connect this into digital audio processor unit using

fiber optic cable.

Power input:

Connect into the power supply (included). Power supply is universal 110VAC/220VAC and output is

12VDC 25 watt. MV720p-HD input is 16VDC max.

The term Memory Card used in this manual refers to one of the following:

USB Flash Drive, Stick Drive, Thumb drive, External Hard drive and Card reader using USB 2.0 and

Internal SATA 2.5” solid state or laptop hard drive.

LOOP VIDEO AFTER POWERING UP:

To loop video files after powering up, you have to do at least 2 items:

1. Copy the video files into the memory card.

2. Create autoplay.txt using notepad etc. The content of autoplay.txt can be anything or even empty.

The MV720p-HD needs autoplay.txt as a pointer to locate the drive that will be used to play the file.



If playing through USB port, autoplay.txt is NOT required.



Autoplay.txt is required only when playing from the built in SATA hard drive.



Files in the memory card will be sorted and played numerically.

Here is an example of the memory card content for loop after powering up:

F:/

1Cat.ts

2Bird.ts

3Dog.ts

autoplay.txt (could be empty)

After powering up, the MV720p-HD will play 1Cat.ts and then 2Bird.ts and then 3Dog.ts and then loop

back to play 1Cat.ts.

SEAMLESS LOOP VIDEO AFTER POWERING UP:

The MV720p-HD will only seamlessly loop a single video file, it will not seamlessly loop multiple files.

To seamlessly loop a video file after powering up, you have to do at least 2 items:

1. Copy the video file into the memory card.

2. Create autoplay.txt using notepad etc and add endtime=xxx statement (lower case only)

3. xxx is the length of playtime time in seconds.

Here is an example of the memory card content for seamless loop after powering up:

Suppose cat.ts playtime is 30 seconds. Normally the MV720p-HD will loop cat.ts with black screen in

between. To seamlessly loop cat.ts, add endtime=30 statement inside autoplay.txt.

F:/

Cat.ts

autoplay.txt

Content of autoplay.txt is: endtime=30.

Make sure that endtime is in lower case letters only.

After powering up, the MV720p-HD will play Cat.ts.

30 seconds after it starts playing cat.ts, MV720p-HD will automatically (instantly) loops back to the start.

It will loop back instantly without black screen in between.

To loop several files seamlessly, you have to join the files together and create a single file. To join the

files, you can use DOS binary function OR use join utility software. Please contact Akman Inc for info.

Example:

F:/

Cat.ts

Bird.ts

Dog.ts

In the root directory you have Cat.ts, bird.ts and dog.ts. To seamlessly loop these file, join the 3 ts files

into a single ts file. Suppose the new join file is New.ts and the total playtime is 120 seconds. Replace the

3 files in the memory card with this new.ts file. Create autoplay.txt where the content is endtime=120

Here is the new F drive.

F:/

New.ts

Autoplay.txt (content is endtime=120, lower case letters only).

After powering up, the MV720p will automatically plays new.ts and after 120 seconds will instantly loops

back to start.

NOTE:

When joining the files together, the files have to be of the same type, same bit rate and same resolution.

You can not join different types of files together.

AUTOMATICALLY PLAY different video files with time delay in between

(TIMER Mode):

In Timer mode, the MV720p-HD will play lines 80=xxx to 99=xxx in the autoplay.txt.

To enter timer mode you have to set 2 items, number of files to play and time delay. Use the IR

remote control and do the following:

Set number of files:

SLOW SLOW x SLOW. X is the number of files to play and is a value from 1 to 20.

If x=0, the MV720p will exit timer mode.

Set time delay:

A-B A-B x A-B where X is the number of time delay in minutes.

If x=0, the MV720p will exit timer mode.

To use this mode you have to do the following items:

1. Copy the loop video files into the root of the memory card. This file will automatically loop after

powering up.

2. Create a file folder and copy the files that you want to automatically play (with time delay in between)

inside this file folder.

3. Create autoplay.txt and define lines 80 to 99 in the autoplay.txt

4. Set the time delay

5. Set the number of files that you want to sequentially play.

And here is how the MV720p-HD operates:

After powering up, the MV720p-HD will loop the root files. After a set time delay, it will automatically

play 80=xxx file and then return to play the root again. . After another time delay, it will automatically

play 81=xxx file and then return to play the root again. After playing the last file, MV720p-HD will

repeat the cycle. This mode is called TIMER MODE.

SET TIME DELAY (Timer mode, use A-B key):

To enter timer mode use IR remote and do the following:

A-B A-B x A-B where X is the number of time delay in minutes.

If x=0, the MV720p will exit timer mode.

Suppose you want to set time delay to 15 minutes.

While the MV720p is booting up or while playing a video, press the following key sequence:

A-B A-B 15 A-B.

The time delay is now set to 15 minutes.

To exit timer mode use IR remote and do the following:

A-B A-B 0 A-B

SET NUMBER OF FILES (Timer mode, use SLOW key):

In Timer mode, set lines 80=xxx to 99=xxx in the autoplay.txt.

Use the IR remote control and do the following:

Suppose you only want to play 4 files (line 80 to line 83).

While the MV720p is booting up or while playing a video, press the following key sequence: \

SLOW SLOW 4 SLOW

The number of files to play is now 4 (lines 80 to 83).

To exit timer mode use IR remote and do the following:

SLOW SLOW 0 SLOW

NOTE: The MV720p will remember this Timer Mode setting.

Example of the memory card content for timer mode:

Tiger.ts

autoplay.txt

VIDEO …… (file folder)

Bird.ts

Cat.ts

Dog.ts

Lion.ts

And here is an example of the autoplay.txt for timer mode:

80=VIDEO/Bird.ts

81=VIDEO/Cat.ts

82=VIDEO/Dog.ts

83=VIDEO/Lion.ts

Suppose the time delay is set a 15 minutes and the number of files to play is 4 (lines 80 to 83).

Here is how the MV720p-HD operates:

After powering up, MV720p-HD will loop Tiger.ts. After 15 minutes delay, it will play Line 80 (Bird.ts)

and then return to loop the root files. After 15 minutes delay, it will play Line81 (Cat.ts) and then return

to play the root files again etc. After playing the last file (Lion.ts), it will repeat the cycle again.

PLAY VIDEO USING BUILT IN PUSH BUTTON:

MV720p-HD has 3 built in digital input. They are configured as IN1, IN2 and IN4, lines 01 to 06 in the

autoplay.txt.

To play file(s) using push buttons you have to do the following items:

1. Copy the loop video files into the root of the memory card. This file will automatically loop after

powering up. Note: Add endtime=xxx statement to seamlessly loop this file.

2. Create a file folder and copy the files that you want to play using the push buttons inside this file

folder.

3. Create autoplay.txt using wordpad, notepad etc and save it into the root of the memory card. The

content of autoplay.txt contains the instruction on how you want to play the files using the push

buttons. MV720p built in input plays lines 01 to 06 in the autoplay.txt.

Example of the memory card content for push button input:

Tiger.ts

autoplay.txt

VIDEO …… (file folder)

Bird.ts

Cat.ts

Dog.ts

Lion.ts

Tiger.ts

Bear.ts

Content of autopl ay.txt for push button input:

01=VIDEO/bird.ts

02= VIDEO/dog.ts

03= VIDEO/cat.ts

04= VIDEO/lion.ts

05= VIDEO/tiger.ts

06= VIDEO/bear.ts

endtime=60

In this example, the video files are stored inside VIDEO folder.

60 seconds after playing tiger.ts, the MV720p-HD will instantly loops back.

When IN1 is momentarily shorted to ground (01), bird.ts will play.

If IN2 is momentarily shorted to ground (02), dog.ts will play.

If IN4 is momentarily shorted to ground (04), lion.ts will play.

If IN1 + IN2 are momentarily shorted to ground(1+2=3), cat.ts will play.

If IN1+ IN4 are momentarily shorted to ground (1+4=5), tiger.ts will play.

If IN2+ IN4 are momentarily shorted to ground (2+4=6), bear.ts will play.

For inputs 1,2 and 4 you can use single pole push butto ns.

For inputs 3,5 and 6, use double pole push buttons.

Push button is wired normally open, this means when idling the contacts are open (not connected).

If you are using single pole push button only, you need to use diodes to prevent false trigger. You

can use any small signal/blocking diodes such as IN4118 etc.

Here is the diode wiring diagram:

Push buttons are single pole, normally open contact.

CONVERT MV720p-HD built in input into IR MODE:

Use this if you want to use NEXT, PREV, PAUSE/PLAY, STOP and VOL+/- functions using push

buttons through the MV720p-HD built in digital input.

NOTE: NEXT and PREV function will play lines 60 to 79 only.

To ENTER IR mode use the IR remote keys and press the following key sequence:

CLEAR CLEAR x CLEAR where x is a number between 1 to 20

To play 6 files, press CLEAR CLEAR 6 CLEAR

To exit IR mode, set the number of files to 0.

To EXIT IR mode press: CLEAR CLEAR 0 CLEAR

In IR mode, the NEXT/PREV input (input 2 and input 4) of the MV720p -HD will play lines 60=xxx

to 79=xxx in the autoplay.txt.

MV720p-HD has a total of 6 built in input. In this mode, these inputs operate as follows:

IN1 operates as PAUSE/PLAY.

IN2 operates as PREV (previous, for lines 60 to 79 only).

IN4 operates as NEXT (next, for lines 60 to 79 only).

IN3 (IN1+IN2) operates as STOP.

IN5 (IN1+IN4) operates as VOL + (volume up).

IN6 (IN2+IN4) operates as VOL- (volume down).

To use the IR mode, you have to do the following:

1. Copy the loop video files into the root of the memory card. This file will automatically loop after

powering up.

2. Create a file folder and copy the files that you want to play using the Prev/NEXT input inside this file

folder.

3. Set the number of files to play. Use CLEAR key of the IR remote. This function sets the number of

files to play using Next/Prev input. It will also causes the MV720p-HD to enter the IR mode. If the

number of file is 0, the MV720p-HD will automatically exit the IR mode.

4. Define lines 60 to 79 in the autoplay.txt

SET the NUMBER of FILES TO PLAY (use CLEAR key):

Setting the number of files between 1 to 20 will cause the MV720p-HD to automatically enter the IR

mode. The number of files function will be used only by the NEXT/PREV input and plays lines 60 to 79

in the autoplay.txt.

To set the number of files to 6, press the following key sequence: CLEAR CLEAR 6 CLEAR

The MV720p is now in IR mode and is set to play 6 files.

The Prev/Next input will sequentially plays lines 60=xxx to 65=xxx in the autoplay.txt.

To EXIT IR mode, press: CLEAR CLEAR 0 CLEAR

NOTE: The MV720p will remember this IR setting.

Example of the memory card content for IR mode:

Tiger.ts

autoplay.txt

VIDEO …… (file folder)

Bird.ts

Cat.ts

Dog.ts

Lion.ts

Here is an example of the autoplay.txt, set to play 4 files using NEXT/PREV:

60=VIDEO/Bird.ts

61=VIDEO/Cat.ts

62=VIDEO/Dog.ts

63=VIDEO/Lion.ts

After powering up, the MV720p-HD will loop Tiger.ts.

If NEXT input is triggered, line 60 will play (Bird.ts) and then return to loop the root. If NEXT input is

triggered while playing bird.ts OR while looping the root, line 61 will now play (Cat.ts) and then return to

loop the root. If NEXT input is triggered while playing Cat.ts OR after while looping the root file, line 62

will now play (Dog.ts) and then return to loop the root files etc.

After playing the last file, MV720p-HD will repeat the cycle.

If PREV is triggered, MV720p-HD will play the previous line.

SYNC a GROUP of MV720p-HD’s:

Use this mode if you want a group of MV720p to play in sync together to create a single video

presentation.

To sync together a group of MV720p-HD’s, you need 1pc IN6 and the sync board(s). Please refer to the

IN6 section below.

The IN6 has a 4 pole dipswitch located at the rear. Switch is OFF if it is in UP position and ON if in

DOWN position.

The IN6 is in sync mode if switch #3 (JP3) is ON (switch is in down position).

When IN6 is in SYNC MODE, it will automatically send SYNC command 90 seconds after powering up.

Switches 1 and 2 of the dipswitch are for the sync command delay.

JP1and JP2 are OFF ……… Sync command will be issued every 30 minutes.

JP1 is ON, JP2 is OFF ……… Sync command will be issued every 1 hour.

JP1 is OFF, JP2 is ON ……… Sync command will be issued every 2 hours.

JP1 is ON, JP2 is ON ……… Sync command will be issued every 3 hours.

The sync board itself does not have any switches or settings.

Note: The MV720p’s are sync based on its internal time function not the SMPTE clock.

Here is an example on how to sync 3 MV720p-HD’s:

Note:

IN6 will automatically send SYNC command 90 seconds after powering up and will maintain the sync as

long as it is playing the loop file(s). While playing the loop file, it will maintain the sync periodically.

Once an input is triggered, the sync will be OFF! To return to sync mode again, manually trigger the sync

command by momentarily shorting the UP and Ground terminal.

To expand the sync network, add Sync board only. You do not need to add another IN6. Each sync board

can connect into 2 (or 3) MV720p. Example: To sync 5 or 6 MV720p, you only need to add 1 more sync

board (total 2 sync boards).To sync 9 MV720p, you need to add 3 more sync boards (total 4 sync boards).
