surround sound is planned for Blu-ray Discs, the audio signals can be downmixed to 5.1 or 2 channels for backward compatibility, and the reproduced audio quality can either be at the bit rate of DTS Digital Surround or the lossless mode.

DVD VIDEO (page 11, 149)

A disc format that contains up to eight hours of moving pictures on a disc the same diameter as a CD. A single-layer single sided DVD holds up to 4.7 GB; a double layer single-sided DVD, 8.5 GB; a single layer double-sided DVD, 9.4 GB; double-layer double-sided DVD, 17 GB. The MPEG 2 format is adopted for the efficient video data compression. The variable rate coding technology that changes the data to be allocated according to the status of the picture is adopted for reproducing high-quality pictures. Audio information is recorded in a multi-channel format, such as Dolby Digital, allowing for a realistic audio presence.

DVD-R(page 11, 148)

A DVD-R is a recordable disc that is the same size as a DVD VIDEO. Contents can be recorded only once to a DVD-R, and will have the same format as a DVD VIDEO. The DVD-R has two different modes: VR mode and Video mode.

DVDs created in Video mode have the same format as a DVD VIDEO, while discs created in VR (Video Recording) mode allow the contents to be programmed or edited.

DVD-RW(page 11, 148)

A DVD-RW is a recordable and rewritable disc that is the same size as a DVD VIDEO. The DVD-RW has two different modes: VR mode and Video mode. DVDs created in Video mode have the same format as a DVD VIDEO, while discs created in VR (Video Recording) mode allow the contents to be programmed or edited.

DVD+R (page 11, 148)

A DVD+R (read “plus R”) is a recordable disc that is the same size as a DVD VIDEO. Contents can be recorded only once to a DVD+R, and will have the same format as a DVD VIDEO.

DVD+RW (page 11, 148)

A DVD+RW (read “plus RW”) is a recordable and rewritable disc. DVD+RWs use a recording format that is comparable to the DVD VIDEO format.

Film-based software, Video-based software (page 112)

DVDs can be classified as Film-based or Video-based software. Film-based DVDs contain the same images (24

frames per second) that are shown at movie theaters. Video-based DVDs, such as television dramas or sitcoms, display images at 30 frames (or 60 fields) per second.

Frame (page 113)

Images that comprise moving pictures. The moving pictures consist of 30 frames per second.

Hard disk drive (page 5, 11)

A hard disk drive is a whole mechanical system that consists of disks and drive. Disks are flat, circular, rigid plates coated with a thin magnetic media. Magnetic heads record data on the rapidly spinning disks, and this enables the speedy and efficient reading and writing of data.

HDMI (High-Definition Multimedia

Interface) (page 23, 102, 105)

HDMI is an interface that supports both video and audio on a single digital connection. The HDMI connection carries standard to high definition video signals and multi-channel audio signals to AV components such as HDMI equipped TVs, in digital form without degradation.

The HDMI specification supports HDCP (High-bandwidth Digital Contents Protection), a copy protection technology for digital entertainment contents for HDMI.

HDV (HDV format) (page 39)

A video format developed for DV cassettes to record and play high- definition pictures.

The server supports Interlace format signals of 1080 effective scanning lines (1080i).

When a compatible digital video camera is connected, the server can record the imported pictures on the HDD or a BD in the original high-definition picture quality.

Interlace format (page 101, 103)

Interlace format shows every other line of an image as a single “field” and is the standard method for displaying images on television. The even number field shows the even numbered lines of an image, and the odd numbered field shows the odd numbered lines of an image.

IP Address (page 121)

Device ID information used according to TCP/IP (Transmission Control Protocol/ Internet Protocol) on the network. IP addresses are expressed as a sequence of numbers in one to three digits separated by dots (e.g., 192.168.0.2).

LPCM (Linear PCM) (page 52, 114) A digital audio format that does not cause deterioration in data compression and expansion.

MAC Address (Media Access Control Address) (page 117) Unique numbers assigned to each LAN terminal to identify devices connected to the network.

You can check the server’s MAC address in [Settings] – [Device Information].

Metadata (page 137)

Content information that the AMG database service provides in the Internet (e.g., title names of music CDs and BD/ DVD movies). Metadata contains artist names, genres, credits, copyright info, product numbers, etc.

Modem (page 26)

Device used for Internet connection. Modems are usually connected to a router in a home environment. Either a DSL Modem or a cable modem can be used, depending on the line connecting to the Internet service provider.

MPEG-2(page 55)

One of the video data compression

 

schemes established by the Moving

 

Picture Experts Group (MPEG), which is

 

 

adopted for DVD VIDEOs and digital

Additional

 

broadcasts worldwide. The scheme

 

specifies MPEG-2 PS (Program Stream)

 

for recordable media such as a DVD

 

VIDEO, and MPEG-2 TS (Transport

Information

An audio file format that compresses

Stream) for digital broadcasts and other

 

communications.

 

MP3 (page 52, 111)

 

PCM signals into 1/10 of its original

 

size.

 

Parental Control (page 118)

 

A function of BD-ROMs/DVD VIDEOs

 

to limit playback of the disc by the age of

 

the users according to the limitation level

 

in each country or area. The limitation

 

varies from disc to disc; when it is

 

activated, playback is completely

 

prohibited, violent scenes are skipped or

 

replaced with other scenes and so on.

 

PCM (page 114)

 

Pulse Code Modulation is one of the

 

methods for converting analog signals to

 

digital data. The analog signal is

 

sampled regularly at uniform intervals,

 

and then quantized to a series of symbols

 

in a digital code. The quality of data is

 

determined by the sampling frequency

 

per second, and the quantization bit rate.
