MEDIACAST

Media distribution via TV broadcast infrastructure (push VOD)

MEDIACAST allows delivery of digital media, such as video, music and photos over-the-air, using existing TV broadcast channels so broadcasters can distribute OTT content.

Streaming video requires a consistent high bandwidth internet connection, via cable or fiber. In many circumstances, such connection is not available, like in rural areas and in mobile networks. Delivery of digital media over wireless technologies is still unreliable and expensive.

 

How does MEDIACAST work ?

By utilizing bandwidth that is available in the existing TV broadcast, MEDIACAST is able to stream digital media to DVRs, STBs, TVs that have storage capability and mobile TVs - smartphones, tablets equipped with TV receiver.

By utilizing broadcast technology, VOD content, even HD content, can be stored in the device and played back without interruptions caused by unstable IP links throughput.

The media can be selected by user via an app. The media can be unlocked via IP channel. The downloaded media can be optimized for size and encoding standard on the server for the receiving player.

What are the components ?


The MEDIACAST platform consists of the following elements:


•    MEDIACAST server, which serves FEC encoded and encrypted digital media to the broadcast station
•    MAINDATA IP encapsulator, which encapsulates an IP stream into the TV broadcast stream

•    Broadcast receiver with MEDIACAST client, which can be a DVRs, STBs, TVs that have storage capability and mobile TVs - smartphones, tablets equipped with TV receiver and a low bandwidth internet back channel, that gets the decryption key from the DRM server and provide usage reports

MEDIACAST transmission may utilize unused bandwidth of the TV broadcast station, therefore significantly reducing the costs of the total system setup.
