There was a time when a neat camera trick was enough to have viewers at home suitably entertained by broadcast standards. Those days, however, are long gone. Broadcasting has become much more technologically complex, with features designed to make a visual impact, meaning that having closed caption software, with which to provide a valuable viewer service, is not enough anymore. While caption and subtitle software is very much necessary to provide the services expected from socially considerate national broadcasters, 스포츠중계 these are just part of the overall picture.
With all of the extra features that are commonly used, effective ancillary data processing capabilities that can marry all of the various parts together are now an essential. In the modern world of broadcasting, it is impossible to satisfy the viewers with plain video and audio. There are a series of features in the image to be seen on a television screen that only the relevant technology can produce, and which the public are now conditioned to see. In sports broadcasting, for example, the time, either that has elapsed or is remaining in a match or event, needs to be displayed clearly and attractively, usually in the top left of right corner of the screen. When it comes to news broadcasts, items such as the news programme logo and reporter names are commonly displayed. In essence, practical effects that enhance the viewing experience have become basic features to the viewing public. The problem is that this type of ancillary data is only part of the mesh of effects, features and images that needs to come together to meet the modern standards of broadcasting. And, the most complex aspect of this is the need to cope with the variety of different coding systems, file types and digital television technologies that are used. It is therefore essential that ancillary data is integrated to allow for a smooth flow of data from one system to another
