As part of its work to develop a next generation of broadcast standard, the Advanced Television Systems Committee has issued a call for proposals for the "physical layer" or core transmission system that would be the basis of a new standard known as ATSC 3.0.
No time table has been set for the completion or deployment of the new standard. But work on ATSC 3.0 is deployed is intended to allow broadcasters to deliver a wide array of new services and features, including Ultra High-Definition, the distribution of content to mobile devices and improved spectrum efficiency.
Initial responses to the call for proposals are due on Aug. 23. Detailed technical descriptions of proposals are due on Sept. 27.
"Technology continues to advance and we are always looking to the horizon," noted ATSC President Mark Richer in a statement. "Internet technology now permeates the consumer experience, and mobility has become a requirement. As we look forward to next-generation television standards, we want to take advantage of advances in compression and transmission technologies that will keep millions of people informed and entertained through broadcasting's inherently efficient one-to-many architecture."
Glenn Reitmeier, ATSC chairman, added in another statement that "the ATSC 3.0 effort is a crucial time for broadcasters, professional equipment manufacturers, consumer device manufacturers and all stakeholders to collaborate and create the future capabilities of over-the-air broadcasting."
The ATSC 3.0 Technology Group (TG3) will develop the Standards and Recommended Practices for the next-generation digital terrestrial TV broadcasting system.
In calling for proposals, TG3 is looking for "ATSC 3.0 physical layer technologies to define the modulation and error coding technologies that will provide a foundation for the next terrestrial broadcast system," for both fixed and mobile devices, the group noted.
In addition to spectrum efficiency, the ability to support increased data rates necessary for Ultra HD, the group is also looking for technologies that would enable a smooth transition to ATSC 3.0 and for approaches that would make ATSC as compatible as possible with transmission standards outside the U.S.
"ATSC 3.0 is expected to provide robust mobile services to devices that move, such as phones, tablets, laptops and personal televisions," Richer noted in a statement. "Since these devices are likely to move across borders, it's highly desirable that the specification contains core technologies that will have broad international acceptance and enable global interoperability."
