Glossary AVCHD AVCHD is a new format (standard) for high definition video cameras that can be used to record and play high-resolution HD images. BD-J Some BD-Video discs contain Java applications, and these applications are called BD-J. You can enjoy various interactive features in addition to playing normal video. BD-Live This is a BD-Video (BD-ROM version 2 Profile 2) that supports the new functions such as Internet connection, etc. in addition to the BONUSVIEW function. Bitstream This is the digital form of multi-channel audio data (e.g., 5.1 channel) before it is decoded into its various channels. BONUSVIEW (Final Standard Profile) This is a BD-Video (BD-ROM version 2 Profile 1 version 1.1) that supports the new functions such as Picture-in-picture, Secondary Audio, and Virtual Package, etc. DivX DivX is a popular media technology created by DivX, Inc. DivX media files contain highly compressed video with high visual quality that maintains a relatively small file size. DNS Server A server which acts like a telephone directory and translates Internet domain names into IP addresses. Dolby Digital This is a method of coding digital signals developed by Dolby Laboratories. Apart from stereo (2-channel) audio, these signals can also be multi-channel audio. Dolby Digital Plus Multi-channel audio and higher audio quality is made possible using Dolby Digital Plus. BD-Video supports up to 7.1 channel output. Dolby TrueHD Dolby TrueHD is a very high quality audio format that reproduces the studio master audio. BD-Video supports up to 7.1 channel output. Down-mixing This is the process of remixing the multi-channel audio found on some discs into fewer channels. DTS (Digital Theater Systems) This surround system is used in many movie theaters. There is good separation between the channels, so realistic sound effects are possible. DTS-HD DTS-HD is a high-quality, sophisticated audio format used in movie theaters. Previous DTS Digital Surround-compatible equipment can play DTS-HD as DTS Digital Surround audio. BD-Video supports up to 7.1 channel output. Dynamic range Dynamic range is the difference between the lowest level of sound that can be heard above the noise of the equipment and the highest level of sound before distortion occurs. Dynamic range compression means reducing the gap between the loudest and softest sounds. This means you can listen at low volumes but still hear dialog clearly. Film and video DVD-Video are recorded using either film or video. This unit can determine which type has been used, then uses the most suitable method of progressive output. Film: Recorded at 24 frames per second. (Recorded at 30 frames per second as well). Generally appropriate for motion picture films. Video: Recorded at 30 frames/60 fields per second. Generally appropriate for TV drama programs or animation. Frames and fields Frames refer to the single images that constitute the video you see on your television. Each frame consists of two fields. u r Frame Field Field ≥A frame still shows two fields, so there may be some blurring, but picture quality is generally better. ≥A field still shows less picture information so it may be rougher, but there is no blurring. Gateway IP address of the electronic device providing Internet access. Usually called a router IP address. (e.g., 192.168.0.1) HDMI (High-Definition Multimedia Interface) HDMI is a digital interface for consumer electronic products. Unlike conventional connections, it transmits uncompressed digital video and audio signals on a single cable. RQT9184 (ENG) 40 Hub Used for connecting more than one device to the network. IP address A set of numbers which distinguish each device on the network when, for example, connected to the Internet. When using a PC in a LAN to access a PC or device that is not included in the LAN, the IP address is called the local IP address. (e.g., 192.168.0.10) JPEG (Joint Photographic Experts Group) This is a system used for compressing/decoding color still pictures. If you select JPEG as the storage system on digital cameras, etc., the data will be compressed to 1/10-1/100 of its original size. The benefit of JPEG is less deterioration in picture quality considering the degree of compression. LAN (Local Area Network) A group of linked devices in a company, school or home. Indicates the boundaries of a particular network. Local storage This storage area is used as a destination for sub contents for playing virtual packages on BD-Video. LPCM (Linear PCM) These are a kind of PCM format. These are uncompressed digital signals, similar to those found on CDs. MP3 (MPEG Audio Layer 3) An audio compression method that compresses audio to approximately one tenth of its size without any significant loss of audio quality. Pan&Scan/Letterbox In general, DVD-Video are produced with the intention that they be viewed on a widescreen television (16:9 aspect ratio), so images often don't fit regular (4:3 aspect ratio) televisions. Two styles of picture, "Pan & Scan" and "Letterbox", deal with this problem. Pan&Scan:The sides are cut off so the picture fills the screen. Letterbox: Black bands appear at the top and bottom of the picture so the picture itself appears in an aspect ratio of 16:9. PCM (Pulse Code Modulation) This is one format for converting analog audio into digital audio, enabling you to enjoy digital audio with no hassle. Picture-in-picture This is a new function of BD-Video that plays the primary video and secondary video simultaneously. For instance, the function is capable of playing the original movie as the primary video while playing video commentary from the film director on a small screen as a secondary video. Progressive/Interlace The video signal standard of NTSC has 480 interlaced (i) scan lines, whereas progressive (p) scanning uses twice the number of scan lines, and this is referred to as 480p. Using progressive output, you can enjoy watching high resolution video. Router Distinguishes the IP address assigned to each device, such as the PC, and relays the flow of data within the network. Sampling frequency Sampling is the process of converting the heights of sound wave (analog signal) samples taken at set periods into digits (digital encoding). Sampling frequency is the number of samples taken per second, so larger numbers mean more faithful reproduction of the original sound. Subnet mask Enables efficient network use. A set of numbers which identify which part of the IP address allocated to every device connected to the router is the network portion. Virtual package Some BD-Video discs copy data to other media (local storage) and then play the secondary video, secondary audio, and subtitles (sub contents) simultaneously. These functions are called virtual packages. Sub contents are automatically recorded to other media from the Internet or disc prior to playing the virtual package. The playback methods vary depending on discs. 1080i (1125i) In one high definition image, 1080 (1125) alternating scan lines pass to create an interlaced image. Because 1080i (1125i) more than doubles current television broadcasts of 480i, the detail is much clearer and creates a more realistic and rich image.
