1. Introduction
1.1 Orientation
Serial digital interface (SDI) is a good mechanism standardized by SMTP (The Society of Motion Picture and Television Engineers) which is used for digital video interfaces. The data in this method is transferring using coaxial cable. This study case is to produce Channel 4 which is one of the Australian free to air television …show more content…

1.3 Definitions and Limitations
This design should increase operational efficiency and overall profitability based on return on investment (ROE) calculations.
Limitation could be in:-
-estimating and gathering more information about the existing network and applications
-The cost required to update the existing network to IP network.
-Applying mechanism to ensure that the service level agreement is met.

2. Analysis and specification
2.1 Initial condition

Channel 4 has two studios located in Sydney and Melbourne and four free to air television channels (channel4, C4forKids, WOW and QTV). In addition, channel 4 has three types of video contents:-
InProd content is edited by Channel 4 and finished product is sent as SDI streams to be stored in the digital media center, via Studio Router.
ExProd content is provided to Channel4 on solid state media as a digitized video file. These files are stored in the Digital Media center until required.
Live Video Feed is live news and programs to broadcast directly to Australia.
The existing Studio Router takes SDI/ASI input and assign it to many outputs such as MPEG Encoder, Video output, Satellite Uplink or Digital Video Network (DVN) to Media Hub.
There are three DVN that transfer MPEG Encoded videos either from Digital Media Center or live Video from a News Studio to the Media Hub (Figure 1).
