In a 720X 576 pixel PAL SD frame :
Analog to Digital conversion through sampling, quantizing and coding
With 10 bit coding :
(13.5+6.75+6.75)10 = 270 Mbps
Sampled at 48 kHz, 24-bit (20-bit in SD, but extendable to 24 bit) PCM audio is stored, in a manner directly compatible with the AES3 digital audio interface. These are placed in the (horizontal) blanking periods, when the SDI signal carries no useful signal, since the receiver generates its own blanking signals from the TRS.
A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub or concentrator.
Data on a star network passes through the hub or concentrator before continuing to its destination. The hub or concentrator manages and controls all functions of the network.
