Technovision DV-75N

The Technovision DV-75N is a networkable media player that can be synced to others via ethernet.

If you do not need precise synchronization between 2 or more players, then one of our Asus or Briteview media players will be fine for your uses.

Our DVV75Ns contain 16GB internal SD cards that cannot be removed. Video files are transferred to the internal SD via USB.
Please note that the player does not play files directly from a USB device.

The DV75N can be connected via VGA (video only) , HDMI and proprietary AV connection. Video and Audio can be split between the various outputs.

Proper Encoding of Files

This device accomodates a variety of formats and you can read all about them here

That said, the one that I have personally tested for reliability is a .mp4, utilizing h.264 as a codec with an AAC audio format at 48KHZ sampling rate.
I've encoded the AAC at 256kbps. This has been personally tested and it works!

Take note of these export settings from Adobe Premiere:

 

Operation

-connect DV-75N to monitor or projector. power both on. select proper input for device.
-press "v.mode" on remote until you see the configuration menu screen. this is the master screen for the device. It contains 10 menus.
You will only need to use the Basic, Video/ Audio , LAN and Advanced menus + the Play button.

Copying Files to DV-75N

IMPORTANT: make sure that you are using a completely empty thumb drive that is formatted as MS Dos-Fat 32.
Use a program such as Apple's Disk Utility to erase the files. simply dragging them into the trash will not empty the thumb drive.

-connect thumb drive to device
-use remote to select the "basic" menu
-use remote to scroll down to the "storage" section and the "contents field"
-"USB Sync" allows you to copy media to the DV-75N while erasing current files on device.
-"USB Copy" allows you to copy media to the DV-75N without erasing the files on the device.

 

 

Playing Files (for testing in single player mode)

In the "Basic" menu, make sure that "DSP Mode" is set to "standard".
In the "Advanced" menu, make sure that "Multisync Setting/ Mode" is set to "Disable"
Return to configuration menu and select "Play"

Syncing up Media Players (Multisync Mode)

Multiple players can be connected and networked via ethernet cables.
If you are using two players, they can be connected to each other via ethernet.
If you are using more than two players, they should all be connected to an ethernet hub.

Once your files are loaded onto each machine:

Desginate player #1 (or the lowest numbered one) as your server/ controller.

For Each Player:

1-In "Basic" menu/ "System" section set "DSP Mode" to "interactive". (see above)
2-In the "Lan" menu "enable" should be set to "enable" and "DHCP" should be set to "disable"
DO NOT CHANGE THE IP ADDRESS, SUBNET, GW OR DNS SERVER

3-In "Advanced" menu set "mode" to "repeat mode"
4-In "Advanced" menu/ Multisync section set "mode" to "enable"
5-In "Advanced" menu/ Multisync section set "number of multisync players to the number of players that you will be using.

 

6-Return to configuration menu and press 'play' button on all devices.

DO NOT CHANGE THE IP ADDRESSES ON THESE DEVICES
