Streaming Capabilities And System Scalability; Available Unicast Streams - Extron electronics SMP 351 User Manual

Streaming Capabilities and System Scalability

The following tables detail the streaming capabilities of the SMP 351. Data for the tables
was obtained through laboratory testing using optimal bandwidth conditions and can vary
depending on the selected video bit rate.

Available Unicast Streams

Video resolution and bitrate affect the total number of unicast streams (Archive and
Confidence) the SMP 351 can broadcast. The following table compares the selected
resolution and bitrate with the approximate number of unicast streams that will be available.
Changing the resolution or using higher or lower bit rates may increase or decrease the
available number of streams.
Pull Stream Method
(Pixels x Lines @ frame rate)
NOTE: The following configuration options were set on the SMP 351:
Push Stream Method
The number of push unicast streams is one per encode (the SMP 351 has two encodes,
Archive and Confidence).
done on the Archive encode with one pull unicast confidence stream. Recording while
streaming does not reduce the maximum number of pull streams.
