Two separate companies and a group of three companies working together have submitted competing proposals for the audio subsystem of the next-gen ATSC 3.0 television standard, said Mark Richer, president of the Advanced Television Systems CommitteeTec, during a telephone interview today from ATSC headquarters in Washington.
The proposals — submitted in the form of something ATSC calls “registration documents” — came from Dolby Laboratories, DTS and the trio of Qualcomm, Fraunhofer and Technicolor. The proposals were due today, Richer added.
When ATSC issued its call for audio proposals in December 2014, it specified the audio subsystem should give viewers the ability to personalize their audio experience by doing things such as enhancing the dialog portion of the sound, making it possible to select different audio tracks and assistive audio services and having access to other advanced features.
It also called for the proposals to offer a more immersive audio experience for TV viewers in the home as well as those using mobile devices to watch television.
ATSC is on track to release an ATSC 3.0 candidate standard in the first half of 2015, Richer said.
ATSC 3.0 is being written in multiple parts — largely based on the layers of the system. As a result some parts are expected out before others. The first to emerge is likely to be the candidate standard for the physical layer of ATSC 3.0, he said.
