DVB Service provides and manages a single Digital Video Broadcast (DVB) multiplex of live TV
channels to the system. Terrestrial, satellite, and cable TV providers now use a digital rather than analog
transmission systems to deliver their content. Where previously a single frequency was required for each TV
channel, by using digital compression, multiple channels can be provided on a single frequency (known as a
multiplex or bouquet). The DVB service de-multiplexes the individual TV channels on a selected frequency
and makes each individual channel available for multicasting to PC and set-top box users.
DVB Tuners must be connected to a network accessible by the 2nd Network Interface Card (2nd NIC). Go to
Live Channels > Manage Digital Tuners to access this screen. Vision
