When you display the video list, you can see the thumbnails (small pictures to display on the menu) for the video files on the player. To display a thumbnail for a video file, create a JPEG file (horizontal 160 x vertical 120 dots, extension: .jpg) and name it the same as the desired video file, then store it in the video file folder. 119 Useful Facts For photos (On Windows Explorer) Drag and drop files or folders into the “PICTURE” folder.

Audio format refers to the method used when importing audio data from the Internet or audio CDs to a computer and saving it as an audio file. Common formats include MP3 and WMA, etc. MP3: MP3 (MPEG-1 Audio Layer3) is a common audio compression technology developed by the MPEG working group of the ISO (International Organization for Standardization). MP3 can compress audio files to about 1/10 the size of standard CD audio files. WMA: WMA (Windows Media Audio) is a common audio compression technology developed by Microsoft Corporation. The WMA format produces the same sound quality as that of the MP3 format with a smaller file size. AAC: AAC (Advanced Audio Coding) is a common audio compression technology developed by the MPEG working group of the ISO (International Organization for Standardization). The AAC format produces the same sound quality as that of the MP3 format, with a smaller file size. Linear PCM: Linear PCM is an audio recording format without digital compression. You can listen to the sound with the same quality as CD music by recording with this format. What is bit rate? Bit rate refers to the amount of data used to store each second of audio. Generally, higher bit rates provide better sound quality, but require more storage space for the same length of audio. What is the relationship between bit rate, sound quality, and storage size? 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. Note • 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.

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 production 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 Cod...
