2. Product information
1. Stream Pro fi le
A pro fi le de fi nes a set of capabilities, targeting a speci fi c class of applications.
3 stream pro fi les are supported on NGS-D320:
Stream pro fi le Characteristics Target decoding
platform
BASE Supports a limited subset of techniques, simpler to
design, less code, less processing power. Low power, mobile
devices
MAIN
Supports the majority of techniques, more complex to
design, more code, more memory needs & CPU load. Standard PC
NGS-D320 decoder
HIGH Supports the complex techniques, most complex to
design, most code, highest memory & CPU load. High-end workstation
NGS-D320 decoder
2. Levels
A level is a speci fi ed set of constraints that indicated a degree of required decoder performance for a
pro fi le.
A level speci fi es:
- Maximum resolution
- Maximum frame rate
- Maximum bitrate
that a decoder must be capable to decode.
A decoder that conforms to a level must be able to decode all bitstreams encoded for that level and
all lower levels.
The NGS-D320 supports L4.0, L5.0 and L5.1
3. Resolution & Frame Rate
The NGS-D320 supports the following maximum resolutions & frame rates
Maximum resolution
Frame rate Lite (1 stream) Pro (both streams)
60fps 1920x1200 1920x1200
30fps 2560x1600 2560x1600
15fps 4096x2160 4096x2160 (1 stream)
60fps N/A 2560x1600 (1 stream)
30fps N/A 4096x2160 (1 stream)
4. Bitrates
The NGS-D320 supports following bitrates:
- Minimum bitrate: 512Kb/s
- Maximum bitrate:
o
Lite: 12Mb/s
o
Pro: 24Mb/s
5. Pro fi le naming
The pro fi les on the NGS-D320 are named according to following de fi nition:
H.264 <stream profile><bitrate><max resolution><max framerate> (<gdr>)
All pro fi les are IDR pro fi les, except the pro fi les with gdr extension.
IDR stands for “Instantaneous Decoder Refresh”. The IDR pro fi les generate I-frames. I-frames are
sent every 30 frames.
