UB820 is one of the first players to support the HDR10+ format (along with UB320, UB420 and UB9000) and the first player to offer onboard tone mapping for high dynamic range (HDR) and standard dynamic range (SDR) playback. Compared to the Panasonic's previous higher-end UB900 model, UB820 lacks touch-sensitive controls and THX certification.
In fall 1999, [6] THX released the trailer Broadway 2000 for use of the Dolby Digital Surround EX sound system. As a result, an entirely new Deep Note was made from scratch. In this version of the Deep Note, new voices were made using a similar process while voices from the previous version can be briefly hea
Dolby Digital, originally synonymous with Dolby AC-3 (see below), is the name for a family of audio compression technologies developed by Dolby Laboratories. Called Dolby Stereo Digital until 1995, it is lossy compression (except for Dolby TrueHD). The first use of Dolby Digital was to provide digital sound in cinemas from 35 mm film prints.
All sound recording formats, whether digital (Dolby Digital, DTS, SDDS) or analog (Dolby Stereo, Ultra Stereo), can be reproduced in a THX system. THX-certified theaters provide a high-quality, predictable playback environment to ensure that any film soundtrack mixed in THX will sound as near as possible to the intentions of the mixing engineer.
The left and right surround speakers in the bottom line create the surround sound effect. 5.1 surround sound ("five-point one") is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres.

The first and simplest method is using a surround sound recording technique—capturing two distinct stereo images, one for the front and one for the back or by using a dedicated setup, e.g., an augmented Decca tree [20] —or mixing-in surround sound for playback on an audio system using speakers encircling the listener to play audio from ...
In addition to AC-3, some HD DVD players transcode audio compatible with S/PDIF into 1.5 Mbit/s DTS audio. While S/PDIF can carry Dolby Digital Plus at lower bitrates, the HD DVD standard specifies a bitrate for DD+ which is too high for a S/PDIF interface to transmit. Should the player need to decode the audio for a non-HDMI 1.3 receiver, the ...
