Introduction

The DaySequerra MultiMerge2 enables broadcasters to smooth the transition from stereo to 5.1 surround sound by providing viewers with a 24/7 surround sound experience. With MultiMerge2 inline,

5.1 original content is passed unaffected to the viewer while original stereo content is upmixed to a 5.1 surround sound image providing the viewer with a consistent surround experience. The transition between 5.1 and stereo occurs seamlessly without the need of operator intervention. By offering a 24/7

5.1 signal, AC3 meta data will never need to transition between 2/0 and 3/2 mode avoiding the risk of audio ‘clicks’, ‘pops’, and dropouts.

The DTS-Neural Audio patented approach to stereo UpMix avoids taking ‘artistic license’ with content by placing audio exactly where it would be heard in a professional LEDE (Live End Dead End) listening environment. For example, mono or pan-pot stereo will image in front of the listener where as stereo containing depth information, or LtRt encoding, will surround the listener.

The MultiMerge can be used in combination with the DTS-Neural Surround DownMix to in order to pass

5.1 through stereo only facilities thus, eliminating the need for costly Master Control upgrades.
