Generally, higher bit rates provide better sound quality, but require more 

storage space for the same length of audio, so you can store fewer songs on the 

player.

Lower bit rates enable you to store more songs, but at a lower sound quality.

 If you import a song from a CD to your computer at a low bit rate, you cannot improve 

the song’s sound quality by selecting a high bit rate when transferring the song from the 

computer to the player.

Video format refers to the method used when importing video and audio data 

to a computer and saving it as a video file.

Common formats include MPEG-4 and AVC, etc.
MPEG-4: MPEG-4 refers to Moving Picture Experts Group phase 4, developed 

by the MPEG working group of the ISO (International Organization for 

Standardization). The compression format is for video and audio data.
AVC: AVC refers to Advanced Video Coding, developed by the MPEG working 

group of the ISO (International Organization for Standardization). It enables 

reproduction of more vivid images at a lower bit rate. AVC files include four 

profiles, and “AVC Baseline Profile” is one of them. AVC format is based on the 

MPEG-4 AVC standard of the ISO (International Organization for 

Standardization), and since AVC is standardized as the MPEG-4 Part 10 

Advanced Video Coding, it is commonly referred to as MPEG-4 AVC/H.264 or 

H.264/AVC.
WMV: WMV (Windows Media Video) is a video compression format 

developed by Microsoft Corporation. It was built upon MPEG-4, achieves a 

high compression rate, and supports copy control by DRM.

Photo format refers to the method used when importing images to a computer 

and saving them as image files. Common formats include JPEG, etc.
JPEG: JPEG (Joint Photographic Experts Group) is a common image 

compression format developed by the JPEG. JPEG can compress an image file 

to about 1/10 to 1/100 the size of original image files.
