•
Encoding presets for quick recall of specific compression settings
— The
SMP 351 provides 16 standard or customizable presets for saving specific encoding
settings such as H.264 profile, resolution, GOP (group of pictures) length, and bit rate
session management configurations. Users can quickly switch between these presets
to support different applications.
•
Push and pull streaming session management
— The flexibility to apply push and
pull streaming session management makes the SMP 351 compatible with a variety of
H.264 devices and streaming applications.
•
Pull streaming transport protocols
— RTP, RTSP interleaved, and HTTP tunneled
streaming transport protocols may be applied, based on various network conditions or
to aid in firewall navigation.
•
Push streaming transport protocols
— Native RTP and MPEG-2 Transport
Streams (TS) may be applied in unicast or multicast streaming applications. TS may be
transported using UDP or RTP based on network conditions.
•
Session Announcement Protocol (SAP)
and
Session Description Protocol (SDP)
—
SAP and SDP protocols simplify identification of AV source streams in unicast or
multicast push streaming applications.
•
Adjustable recording and streaming bit rates
— Select video bit rates from
200 Kbps to 10 Mbps for video and audio bit rates from 80 Kbps to 320 Kbps based
on the viewing application, storage, streaming or network conditions.
•
Clean switching
— Switching has a clean transition between sources. Distractions
such as visual jumps, glitches, and distortion commonly experienced when switching
between computer and video sources will not be experienced when using the SMP 351.
•
Recording metadata
— Metadata can be assigned to make indexing and searching of
recordings simple including: Title, Presenter, Subject, Description, Publisher, Contributor,
and Date.
•
Metadata text overlay
— Data concerning the recording can be presented and clearly
identified on recording layouts with AV sources and a background image.
•
Uploadable background image files
— Upload PNG image files at resolutions up to
1920x1080 to identify organizational or event information.
•
On-screen display information
— Present device information and status on source
images to aid in troubleshooting and fault finding activities.
•
Onscreen display video time reference
— Text displaying a time reference
(HH:MM:SS Format) can be presented within the onscreen display in the top left corner
of the output signal.
•
System workflow alarms
— Notify monitoring systems or support staff if disk space
is low, encrypted signals are detected, AV signal errors occur, or other error conditions
exist.
•
Alarm reporting
— Automate communication with monitoring systems or support staff
using e-mail via Simple Mail Transfer Protocol.
•
AAC audio encoding
— Standards-based audio compression provides compatibility
with many devices. The bit rate can be adapted to different application requirements.
•
Video encoding quality controls including video resolution, video bit rate, frame
rate, constant or variable bit rate control, GOP length, and audio bit rate
—
Several user controls are available to adjust encoding quality.
•
Auto Input Memory
— When activated, the SMP 351 automatically stores input
sampling, and picture settings based on the incoming signal. When the same signal is
detected again, these image settings are automatically recalled from memory.
