DTS Neural Surround MultiMerge




The Perfect Blend of Stereo and Surround Sound for Your TV Broadcast Facility


DTS Neural Surround MultiMerge technology provides surround sound for DTV viewers whether the original content is stereo or discrete 5.1 surround. MultiMerge's stereo to surround UpMix has outperformed all other methods when evaluated for channel discreteness, envelopment, and original spatial location.

Positioned just ahead of the final audio output of a television facility, MultiMerge provides seamless transitions between stereo (LoRo), stereo matrix (LtRt), and discrete 5.1 audio mixes. Original 5.1 content passes untouched as other content is rendered to a 5.1 surround sound image using the DTS Neural Surround UpMix process.




With MultiMerge placed ahead of a Dolby Digital (AC-3) encoder, a broadcaster can stay in the surround (3/2) mode. This eliminates the clicks, pops and dropouts that occur when transitioning back and forth between stereo (2/0) and surround (3/2). MultiMerge also includes a full-time DownMix (LtRt) output that can be used to feed tape or standard definition broadcast feeds.

DTS Neural Surround MultiMerge Key Features Include:

  • Outperforms all existing upmixing methods for channel discreteness, envelopment, and original spatial location
  • Auto upmix of stereo content to reduce chances of operator error (can also be triggered by GPI)
  • Mute-less 5.1 pass-through to guarantee critical audio is never lost, such as center channel dialog
  • Full-time 5.1 surround outputs for HD feeds
  • Full-time stereo (LtRt) outputs for SD feeds
  • User-selectable input logic can automate unusual audio routing needs for voiceovers, EAS, and split transmission paths

Applications
Television Stations, Network Head-ends, Ingest points, Production studios - Commonly used in front of STL paths, Dolby-E or AC-3 encoders.
