Dolby TrueHD has been developed in order to achieve high-quality entertainment is the next-generation technology of 100% lossless. Dolby TrueHD is designed to provide high-quality sound to home theater to give the impression, and then maximize the ability of (stream) media Blu-ray Disc and HD in the future.
Dolby TrueHD sound to recreate (in bits) was produced in the studio recording and mixing stage, you are presented with the sound quality as close as possible to the audio that was recorded live in concert. Dolby TrueHD is a breakthrough technology to high-definition entertainment.
Dolby TrueHD has led to an unprecedented dynamic range wide sound field, and the effect of high reality to home theater, the listener can enjoy studio-quality surround sound such as those actually on the scene.
Dolby TrueHD is to achieve the ultimate high-definition audio experience.
- 100% lossless audio to reproduce in bits of the original studio master.
- In the Blu-ray disc, for up to 24 bit / 192 kHz maximum.
- In the maximum compression ratio of 4:1, to maximize the amount of disk space of HD, to minimize bandwidth requirements.
- 8 channels can be played in response to up to 16 channels, to take full advantage of the capabilities of Blu-ray Disc.
Why Dolby TrueHD
By adopting a Dolby TrueHD lossless coding technology with 100%, equipment manufacturers and content creators, the sound source that provides the same recording, studio-quality surround sound, to differentiate themselves with other companies.
- Unparalleled sound quality at a rate of 18 Mbps maximum data transfer.
- Deliver up to 16 channels of pure audio.
- 8 audio channels in a full range of standard Blue-ray disk corresponds to the 24-bit / 96 kHz, 5.1 channel audio support 24-bit / 192 kHz maximum.
- Digital connection via a single cable for audio and video using the HDMI.
- Extend the meta-data that allows you to control audio playback with advanced content creators.
- Can be integrated into the bit stream of independent two-channel mix content by author.
- Dialogue normalization feature to keep the volume stable even after switching the Dolby Digital TrueHD and programs.
- Equipped with a dynamic range control to suppress the peak volume without compromising the overall sound quality.
- To reduce the data rate to take advantage of correlation between channels, and achieve efficient lossless downmix matrix.
- Decorrelation using the predictability of the audio.
- Huffman coding is adopted to reduce the bit allocation for frequent value in the data stream, the efficient coding (entropy coding).
- Management of the entire transmission path FIFO buffering to smooth the data rate after Encoding.
