MPEG (Moving Picture Experts Group), MPEG-2, MPEG-4
These are the names for digital compression format standards used for
the encoding of video and audio. Video standards include “MPEG-1
Video”, “MPEG-2 Video”, “MPEG-4 Visual”, “MPEG-4 AVC”. Audio
standards include “MPEG-1 Audio”, “MPEG-2 Audio”, “MPEG-4 AAC”.
WMA (Windows Media Audio)
This is audio compression technology developed by Microsoft
Corporation.
WMA data can be encoded using Windows Media
®
Player.
To encode WMA files, only use applications authorized by Microsoft
Corporation. If you use an unauthorized application, the file may not work
properly.
Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal) at
regular intervals and expressing the height of the wave at each reading in
digitized format (producing a digital signal).
The number of readings taken in one second is called the “sampling
frequency”. The larger the value, the closer the reproduced sound is to the
original.
Speaker impedance
This is an AC resistance value, indicated in Ω (ohms).
Greater power can be obtained when this value is smaller.
o
Video
Progressive (sequential scanning)
This is a scanning system of the video signal that displays 1 frame of video
as one image. Compared to the interlace system, this system provides
images with less flickering and jagged edges.
o
Network
AirPlay
AirPlay sends (plays) contents recorded in iTunes or on an iPhone/iPod
touch/iPad to a compatible device via the network.
WEP Key (network key)
This is key information used for encrypting data when conducting data
transfer. On this unit, the same WEP key is used for data encryption and
decryption, so the same WEP key must be set on both devices in order for
communications to be established between them.
