DTS-HD Master Audio Decoder

Product Details

DTS-HD Master Audio is a lossless extension to the core DTS 5.1 surround format. It is used on Blu-Ray video discs to allow bit-to-bit accurate reproduction of the original studio master. The standard reproduces up to 7.1 audio channels at 24-bit resolution and 96kHz sampling rate. The nature of having the core and extension components allows the DTS-HD MA stream to be decode-able on non DTS-HD capable equipment where only the core 5.1 lossy component is decoded.

Features

  • Transport Stream: Raw DTS-HD bit stream
  • Output Status: Sample rate, number of output channels, output channel configuration, output sample size, amount of input data consumed,decoding status words
  • Error Codes: Reports up to 6 unique error codes
  • API: C callable 'Push' API
  • Compliance: DTS-HD certification
  • Code base origin: DTS
  • Certification: DTS Certification on ADSP-21467/469, and ADSP-21486/487
  • Framework dependencies: None. No dependencies on processor peripherals or registers
  • Framework dependencies: None. No dependencies on processor peripherals or registers
  • Input format: Supports core decoding of all DTS encoded bit streams
  • Reference Code Revision #: V3.25.40
  • Output format: Supports up to 7.1 channels, 32-bit fixed point. The bit stream and/or decoder configuration determine the order of channel placement
  • Output buffer samples per block: 256 samples at 48kHz, 512 samples at 96kHz and 1024 samples at 192kHz
  • Sample Rate: All sampling frequencies specified for DTS-HD decoder (i.e. 32, 44.1, 48, 64, 96, 192kHz)
  • Multi-channel: Single-instancing capable

  • MIPS measured using a lossless encoded MA bit stream at 192kHz and 7.1 output with PBR smoothing running on a ADSP-21469. Note that the Bluray specification only allows DTS-HD MA with 5.1 output at 192kHz.
  • Averaged Peak MIPS have been measured using a four-frame moving average.
  • Code compatible across all ADSP-214xx processor
  • "Data RAM" for one instance, includes Stack, Scratch, Instance/State, minimum input and output single buffers
  • Input buffer size is 32 KiB and output buffer size is 32 KiB
  • Frame size considered is 1024 samples per channel
  • 1 KiB = 1024 bytes
