How to use the AV Connectivity function

What does the "AV Connectivity" mean?

Although a normal ODD cannot be connected to a TV directly, the product can be connected to devices (such as TV) that support USB interfaces and can then be used as an USB memory device. "AV Connectivity" refers to this functionality.

How to use the AV Connectivity function

  1. Hold down the Eject button on the ODD for 1.5 seconds while the ODD tray is open to switch the ODD to AV system support mode. At this time, the LED is lit.
  2. If you hold down the button again, ODD mode is toggled between AV system support mode and general ODD mode.


This product is set to general ODD mode by default. When the power is turned off and on, the mode returns to the default mode.

1) The time to recognize the device may differ depending on the number of files and the capacity of the media device.

Supported media types

CD/DVD types of media written in UDF or ISO are supported. (except for DVD-RAM)

The ISO and UDF formats

To understand the ISO and UDF formats, you have to understand the concept of file systems on storage devices.
Since ODDs only support the ISO and UDF file systems, the data needs to be converted to a file system that the AV system can recognize for the data on the ODD to be used.


  • AV System: Supports the FAT32 file system.
  • File System: When an HDD, DVD/CD media or flash memory device is connected to a computer, Windows Explorer shows the file name, the size and the creation date for the files saved on the storage device, by using the information saved on the file system. In addition, the file system stores the locations of the data that make up the files on the media.
  • ISO: This file system is the most widely used file system for ODDs. This file system is used when users save data onto a media in the ODD by using a disc burning program such as NERO or ROXIO.
  • UDF: This is a file system for ODD media that enables reading and writing data onto the media such as when using an HDD or USB memory device.
    For your reference, you can format a RW media in the UDF file system by right-clicking over the media in Windows Explorer in Windows VISTA or later.

Frequently asked questions

Is there a limit to the number or size of the files?

Up to 3000 files are supported and the files from root directory up to 5 levels can be recognized. The maximum size of a file is just under 4 GB. There is no limit to the size of data saved onto a single disc.

In AV system support mode, it takes longer to recognize a disc.

It takes longer to recognize the discs as data on the ISO/UDF file system is converted to the FAT32 file system for AV systems to recognize and transmit the data.

In addition, the time delay due to the conversion is determined by the number and size of the files saved on the disc. (Approximately 30 seconds is required for 1 GB of data.)

I have connected the ODD but there is no response.

Because the file system conversion takes longer, if you connect a high-capacity disc, the connected device (such as TV) will require some time to recognize the Samsung external-type ODD (1G = approximately 30 seconds).


  • When recognizing the ODD, the LED of the ODD blinks continuously.
  • PCs, TVs, and other devices with insufficient USB bus power will not work correctly if you use only one USB port.
I know my TV supports playing images but I cannot display my images on the TV.

The resolution of the images may not be supported by the TV or the codec (JPG, GIF, BMP, and etc.) may not be supported by the TV. In addition, if the actual image is in a format other than JPG such as in the BMP format, the image will not be displayed even though the image file extension is “JPG”.

Does the AV connectivity function allow me to connect to a device such as a TV that only has video, photo and music playing functions?

The AV connectivity function basically enables connecting an AV device to any device to which a USB memory device can be connected. However, the AV connectivity device may be unable to connect to a device due to a power or compatibility problem.

PLEASE NOTE When writing to a device (such as a USB memory device or external HDD that is connected through the USB interface) is required for some reason, the AV connectivity function does not work.


Since some AV systems have a timeout scheme for recognizing USB devices, if recognizing a device is delayed, the process may time out and the device may not be recognized. This may occur when the disc contains a big file or a number of files.

My TV works as a Personal Video Recorder when an external-type HDD is connected. Can I record data by connecting an external-type ODD to the TV?

Since, at present, the AV connectivity function supports reading data only, you cannot write data to the AV connectivity device.

I cannot play a video file on my TV.

First check if the connected TV supports playing video through a USB interface.

If the TV supports this function, check if the video format is supported by the TV.

The AV connectivity technology is only for recognizing the connected portable ODD, not for automatically detecting the file format and playing the files on the ODD. The function for detecting and playing files needs to be supported by the TV or digital frame.
For supported video, photo and music file formats, refer to the user manual of the device to be connected (e.g. the TV manual).

Can I watch commercial DVD titles on the TV by using the AV connectivity function?

To play DVD titles, you need a recorder that can decrypt the encoded DVD title. However, since most TVs do not support this function, you cannot watch DVD titles by using the AV connectivity function. To watch DVD titles, you have to use a DVD player or DVD playing software that runs on a computer.
