Objectives
The main objective was to show how to reliably distribute multiple live broadcast Satellite TV channels over a wireless IP network using multicast to multiple mobile client devices. In this R&D project we have aimed to develop an initial demonstration / proof of concept that would allow us to engage with prospect customers and specify market- or broadcaster- specific products. The demonstrator would support switching between two transcoded video streams that are multicast over the wireless network (and received via satellite). To assure video quality we have applied FEC and we have aimed at also enabling the use of broadband over the same WiFi access point.
Challenges
For this initial proof of concept, there were a few critical challenges that we were trying to resolve. While we are confident that we can deliver a solution for the transcoding, it was possible that the available transcoding options to support the processing of many streams would result in an impractical or cost prohibitive device. In addition, we believed that implementing FEC will be workable, however it is possible that most optimal way to integrate FEC and SAT>IP is a larger work task than estimated.
System Architecture
A block diagram of the SAT>IP WiFi hotspot is shown in the diagram below, it consists of several key components and technologies:
- DVB Tuners
- Video Processing
- SAT>IP server
- Forward Error Correction (FEC)
- WiFi Access Point
- Client Application
