NextGen TV is an outstanding opportunity for broadcasters to deliver advanced, revenue-enhancing services, including datacasting. However, bandwidth is a sparse commodity in the ATSC 3.0 environment. A key contributing factor is that stations are required to broadcast ATSC 1.0 for at least three years after they begin delivering NextGen TV. As broadcasters look to take advantage of new, exciting data delivery opportunities, channel sharing and bandwidth optimization are critical.
This paper will examine the benefits of the ATSC 3.0 data delivery platform. It will outline how the ATSC 3.0 platform provides an inherently more efficient way of distributing content to a large number of people simultaneously. Moreover, it will explain how the ATSC 3.0 data delivery platform can also be used to distribute data for a multitude of other uses.
In addition, the paper will discuss how NextGen TV broadcasters can implement an ATSC 3.0 datacasting environment in a channel sharing arrangement. The paper will outline strategies for optimizing bandwidth through statistical multiplexing and opportunistic data insertion (ODI). The primary focus of the paper will be ODI, which can be used to optimize various datacasting use cases over a typical broadcast day.
To conclude, the paper will analyze why it is important for broadcasters to operate in a unified solutions environment to best leverage ODI and bring NextGen TV datacasting services to market.
