Preparing Content for the HyperCaster

The TelVue HyperCaster

transmits compressed video content over UDP packets. Content must be

already multiplexed into an

MPEG-2 Transport Stream

, and that transport stream often must have a

constant multiplex rate (note however that does not mean the video elementary stream must have a
constant bit rate). The 4.0 version of the TelVue HyperCaster software supports variable mux rate
Transport Streams, however other equipment in your setup may not, so you may need to investigate
whether your full playout chain can support variable mux rate content.

The equipment receiving these streams can and often will have more stringent requirements.
TelVue

servers can aid with these downstream requirements by changing Program ID values as the

MPEG-2 TS is transmitted. However, other requirements, such as bit rate, frame rate, profile and
level, GOP structure, and more, must be set at the time of file creation or by transcoding or
multiplexing.

CableLabs and ATSC

Two common standards that broadcast video equipment will adhere to are the

CableLabs

set

specifications for VOD

, and the

ATSC

broadcast specifications. If your downstream equipment

requires your files to adhere to either specification, you should select a program that the provider has
verified is compliant to these specifications. If your downstream equipment does not require these
