These fields are different. DLNA uses HTTP as the common content transfer protocol, and HTTP is not suited for broadcast applications. Furthermore, so far DLNA has only selected link protection technologies such as DTCP-IP for the narrowest possible scope, streaming from a media server that is in the proximity of the media renderer. These technologies are not suitable for broadcast applications, and they will not work in any applications in which the server is outside the home network; - Section 4.1.1 of 100/1141A/CDV describes the selected technologies, and the goal has been to maximize the use of existing protocols wherever applicable </li></ul>
