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. Bitstream This is the digital form of multi-channel audio data (e.g., 5.1-channel) before it is decoded into its various channels. 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 Surround EX This is the digital surround system developed by Dolby Laboratories. Dolby Digital Surround EX adds a surround back channel to the traditional 5.1-channel format of Dolby Digital. This creates a sound with greater presence. 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 Pro Logic II Dolby Pro Logic II enables you to play stereo sources on 5.1-channel. Dolby Pro Logic IIx Dolby Pro Logic IIx enables you to play stereo and 5.1-channel sources on 7.1-channel. 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. 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-ES DTS-ES adds a surround back channel to the traditional 5.1-channel format of DTS. This creates a sound with greater presence. 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. DTS NEO:6 DTS NEO:6 enables you to play stereo and 5.1-channel sources on 6.1-channel. DTS 96/24 DTS 96/24 provides 96 kHz sound at up to 24 bits. The 96 kHz/24 bit high frequency sounds are played through multiple channels. 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. Final Standard Profile (FSP) 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. Frames and fields Frames refer to the single images that constitute the video you see on your TV. Each frame consists of two fields. u r 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. 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. 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 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 TV (16:9 aspect ratio), so images often don't fit regular (4:3 aspect ratio) TVs. 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. 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. 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. 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 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 TV broadcasts of 480i, the detail is much clearer and creates a more realistic and rich image. 1080p (1125p) In one high definition image, 1080 (1125) scan lines pass at the same time to create a progressive image. Since progressive video does not alternate scan lines like interlace, there is a minimal amount of screen flicker. 24p This is a progressive image recorded at a rate of 24 frames per second. 720p (750p) In one high definition image, 720 (750) scan lines pass at the same time to create a progressive image. Since progressive video does not alternate scan lines like interlace, there is a minimal amount of screen flicker. Reference 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.
