Market Requirements
As we move to fully digital and hybrid systems in both standard and high definition formats, the requirements for
processing are increasing. On a worldwide basis, high definition is becoming more prevalent — with the use of
wide screen and surround sound becoming more popular in home theatre environments.
Because the requirements for processing are increasing, customer demands for more functionality in new 1RU
packages are increasing in parallel. This increased functionality includes:
Up, down, cross and aspect ratio conversion for use in hybrid facilities.

Analog, digital compressed and embedded audio.
Multi-channel audio for surround sound and multiple language applications.
Advanced audio processing such as decompression and compression. This processing (especially
audio compression) requires increased video delay for proper lip sync.
SNMP (Simple Network Management Protocol). This popular protocol, which is used in the telecom
industry for monitoring equipment, has become an important requirement in the television industry.
The ability to take legacy analog signals into the digital domain (with the best processing at the best
price). This step is important — especially before upconverting and compressing video signals.
Interfaces for high definition including optical fiber and DVI-D.
~ Optical fiber is required for long cable runs (>100m / 300ft.).
~ DVI is becoming more popular as an interface into LCD and plasma type picture displays.
Intelligent input processing for alarming and auto-switchover — for purposes of reducing downtime.
Increased use of metadata:
~ Digital video and audio are the data “essence” of a program signal.
~ In today’s facilities, there are many forms of “data about the essence” (or metadata) that travel
along with the video and audio signals.
~ Requirements vary — in some cases, a transparent metadata pass-through is required. In
other cases, you may wish to change the metadata.
Dual power supplies for increased reliability in critical situations.
Front-to-back forced airflow.
