code <.mp3>, <.wma>, <.wav>, or <.m4a> 
(regardless of the letter case—upper/lower).

•  This unit can play back the files meeting the 

conditions below:

 – 

Bit 

rate:

    MP3/WMA: 32 kbps — 320 kbps
    AAC: 16 kbps — 320 kbps
 – 

Sampling 

frequency:

    48 kHz, 44.1 kHz, 32 kHz (for MPEG1)
    24 kHz, 22.05 kHz, 16 kHz (for MPEG2)
    48 kHz, 44.1 kHz, 32 kHz, 22.05 kHz (for WMA)

Playing DivX files

•  This unit can play back DivX files with the extension 

code <.divx>, <.div>, or <.avi> (regardless of the 
letter case—upper/lower).

•  Audio stream should conform to MP3 or Dolby Digital.
•  The file encoded in the interlaced scanning mode 

may not be played back correctly.

•  The maximum bit rate for video signals (average) is 

4 Mbps.

Playing MPEG1/MPEG2 files

•  This unit can play back MPEG1/MPEG2 files with the 

extension code <.mpg>, <.mpeg>, or <.mod>*.

* 

<.mod> is an extension code used for the MPEG2 files 
recorded by JVC Everio camcorders. The MPEG2 files 
with the <.mod> extension code cannot be played 
back when stored on a USB mass storage class device.

•  The stream format should conform to MPEG system/

program stream.

  The file format should be MP@ML (Main Profile at 

Main Level)/SP@ML (Simple Profile at Main Level)/
MP@LL (Main Profile at Low Level).

•  Audio streams should conform to MPEG1 Audio 

Layer-2 or Dolby Digital.

•  The maximum bit rate for video signals (average) is 

4 Mbps.

Playing JPEG files

•  This unit can play back JPEG files with the extension 

code <.jpg>, or <.jpeg>.

•  This unit can play back JPEG files that are at 32 x 32 to 

8 192 x 7 680 resolution.

  It may take time to display the file depending on its 

resolution.

•  This unit can play back baseline JPEG files. 

Progressive JPEG files or lossless JPEG files cannot be 
played.
