AAC (page 52)

“Advanced Audio Coding” is a digital audio codec adapted for digital broadcast. It features a high compression rate and high quality audio comparable to music CDs.

ATRAC (page 52)

“ATRAC Advanced Lossless” is a lossless audio compression technology that compresses and expands CD audio data completely, thus reproducing the original CD quality audio.

ATSC (page 56)

A technical standard for digital broadcasts in the U.S. The specification adapts MPEG-2 for video compression, and AC-3 for audio compression.

AVCHD (page 11, 149)

The AVCHD format is a high definition digital video camera format used to record SD (standard definition) or HD (high definition) signals of either the 1080i specification*1 or the 720p specification*2 on DVDs, using efficient data compression coding technology. The MPEG-4 AVC/H.264 format is adopted to compress video data, and the Dolby Digital or Linear PCM is used to compress audio data. The MPEG-4 AVC/H.264 format is capable of compressing images at higher efficiency than that of the conventional image compression format. The MPEG-4 AVC/ H.264 format enables a high definition (HD) video signal shot on a digital video camera recorder to be recorded on DVDs in the same way as for a standard definition (SD) television signal.

*1 A high definition specification that utilizes1080 effective scanning lines and the interlace format.

*2 A high definition specification that utilizes 720 effective scanning lines and the progressive format.

BD-R(page 11, 148)

BD-R (Blu-ray Disc Recordable) is a recordable, write-once Blu-ray Disc, available in the same capacities as the BD below. Since contents can be recorded and cannot be overwritten, a BD-R can be used to archive valuable data or storing and distributing video material.

BD-RE(page 11, 148)

BD-RE (Blu-ray Disc Rewritable) is a recordable and rewritable Blu-ray Disc, available in the same capacities as the

BD below. The re-recordable feature makes extensive editing and time- shifting applications possible.

BD-ROM(page 11, 149)

BD-ROMs (Blu-ray Disc Read-Only Memory) are commercially produced discs and are available in the same capacities as the BD below. Other than conventional movie and video contents, these discs have enhanced features such as interactive content, menu operations using pop-up menus (see below), selection of subtitle display, and slideshow. Although a BD-ROM may contain any form of data, most BD ROM discs will contain movies in High Definition format, for playback on Blu- ray Disc players.

Blu-ray Disc (BD) (page 11)

A disc format developed for recording/ playing high-definition (HD) video (for HDTV, etc.), and for storing large amounts of data. A single layer Blu-ray Disc holds up to 25 GB, and a dual-layer Blu-ray Disc holds up to 50 GB of data.

Chapter (page 40, 81)

Sections of a picture or a music feature that are smaller than titles. A title is composed of several chapters. Depending on the disc, no chapters may be recorded.

Copy protection signals (page 98)

Copy restriction set by copyright owners, etc.

These signals are included in some software or TV programs and restrict recording.

Cover Art (page 32, 77, 88)

The artwork displayed on the front cover of pre-recorded CD, DVD, and Blu-Ray discs.

CPRM (page 98)

“Content Protection for Recordable Media” is a technology for protecting digital entertainment content on recordable media.

Downmix (page 119)

A process in which surround sounds are converted to have fewer channels than the original source.

DHCP (Dynamic Host Configuration Protocol) (page 121)

A set of rules to automatically assign settings necessary for network communication.

Usually the router or the Internet service provider’s server functions as the DHCP server.

DLNA (Digital Living Network Alliance) (page 74)

An association that formulates audio/ photo/video distribution among PCs and other digital devices in a home network environment, or the format itself. DLNA certified devices are interoperable with each other, thus making them easy to communicate on the network.

Dolby Digital (page 114)

Digital audio compression technology developed by Dolby Laboratories. This technology conforms to multi-channel surround sound. The rear channel is stereo and there is a discrete subwoofer channel in this format. Dolby Digital provides the same discrete channels of high quality digital audio found in “Dolby Digital” theater surround sound systems. Good channel separation is realized because all of the channel data is recorded discretely and little deterioration occurs because all channel data processing is digital.

Dolby Surround (Pro Logic) (page 119)

Audio signal processing technology that Dolby Laboratories developed for surround sound. When the input signal contains a surround component, the Pro Logic process outputs the front, center and rear signals. The rear channel is monaural.

DRM (Digital Rights Management) (page 53)

Technologies for protecting the copyright of digital content, mainly by limiting its usages and copying.

DTS (page 114)

Digital audio compression technology that DTS, Inc. developed. This technology conforms to multi-channel surround sound. The rear channel is stereo and there is a discrete subwoofer channel in this format. DTS provides the same discrete channels of high quality digital audio.

Good channel separation is realized because all of the channel data is recorded discretely and little deterioration occurs because all channel data processing is digital.

DTS-HD(page 59)

DTS-HD is an extended format of the Coherent Acoustics audio coding system, which also encompasses DTS Digital Surround, DTS-ES, and DTS 96/

24.DTS-HD is highly flexible in supporting the number of discrete surround sound channels. While 7.1ch
