Bit-rate refers to the average amount of data which is used by one second of audio. Bit-rate is measured by kilobits (1000 bits/sec). Most people use an MP3 with 128 kilobits per second, which is the benchmark for a good quality playback; the audio is very similar to radio quality. A general rule to follow is the higher the bit-rate, the better the sound.

Frequency Respone
20 Hz - 20,000 Hz
Video Capabilities
Video Format refers to the type of video files that a device can display, and may also be known as a video codec. MPEG1 - This handy format is often used by digital cameras and cheaper camcorders to capture small motion video clips. It is also the compression format used to create Video CDs. Because it¿s so easily transferable, it is commonly used for posting clips on the Internet or in e-mails. \r\nMPEG2 - Commercial DVD movies, recorded DVD discs, and digital satellite TV all use MPEG2 video compression to deliver high-quality pictures. MPEG2 is also used in TiVo-based hard disk video recorders. \r\nMPEG4 - The newest, most flexible MPEG codec which is increasingly used by both streaming and downloadable Web content. \r\nJPEG or Joint Photographic Experts Group - A codec for full-color digital image storage, it is often the format of pictures on the Web. JPEG takes the human eye's inability to see minute color changes and removes portions of data from the original picture file. This makes the file a lot smaller and easier to transfer but with very little `naked eye¿ quality loss.
Video Format
MPEG-4, H.264, M4V, Mov
