Network Bandwidth and OmniStream Compression

When sending video and audio over a network, the available bandwidth needs to be managed. Gigabit Ethernet

switches are very common and can take advantage of installed Category 5e cable. 10-Gigabit Ethernet switches

are available, but are more expensive per port and require Category 6A cable or better. The chart below shows

uncompressed data rates for common resolutions. These data rates exceed the available bandwidth of Gigabit

Ethernet, but using the compression technology in OmniStream, this video can be streamed over cost-effective

Gigabit networks.

Resolution

Data Rate*

1920 x 1080p 30 Hz

2.2 Gbps

1920 x 1080p 60 Hz

4.5 Gbps

3840 x 2160p 30 Hz

8.9 Gbps

3840 x 2160p 60 Hz

17.8 Gbps

OmniStream compresses the source data at the encoder, before it is sent out over the network. This process is

known as

encoding

. OmniStream uses VCx and VC-2 compression, which are intermediate compression schemes

and is much more desirable than using a interframe compression scheme, such as H.264 or H.265. Interframe

codecs are typically used by cable or internet providers and use very aggressive bit rates (low bandwidth) with high

latency (delay), which results in lag. VCx and VC-2 provide both high quality (high bit rates) and very low-latency for

a much more desirable viewing experience.

* Data rate is shown without compression.

Streams

Sessions

The term

stream

is used throughout this manual, to describe the different types of signals that are transmitted over a

network. For example, if a blu-ray player is connected to an encoder, both video and audio are sent to the encoder

over an HDMI cable. The term

video stream

is used to identify the video portion of a signal and

audio stream

identifies the audio portion of the signal.

session

is a way of organizing audio and video streams. The session identifies each stream with a unique

multicast

IP address

and

UDP port

assignment. This provides an address to determine where the package of audio and video

should be sent.

Figure 1.2

illustrates how a session encapsulates a video and audio stream.

NOTE:

Sessions are not limited to only video and audio streams. Control data, such as IR and

RS-232, as well as AES67 audio, can also be contained within a session. These topics will be

covered in a later chapter.
