2 Basic Operation and Configuration

The parameters in the Encoding section will have a significant
impact on the quality and bandwidth requirements of the video
stream. In general it is recommended that the default values
are used initially, and then individual parameters can be
modified and tested incrementally to determine if the
bandwidth and quality requirements are met.
For the video streams, the Codec options are H.264 Main or
MJPEG.
The Bit Rate parameter is only used when the Rate Control
parameter is set to CBR (Constant Bit Rate). With the CBR
setting, the system attempts to keep the video at or near the
target bit rate.
The I-Frame Interval parameter controls the number of P-frames used between I-frames. I-frames are
full frames of video and the P-frames contain the changes that occurred since the last I-frame. A
smaller I-Frame Interval results in higher bandwidth (more full frames sent) and better video quality. A
higher I-Frame Interval number means fewer I-frames are sent and therefore results in possibly lower
bandwidth and possibly lower quality.
The Resolution parameter controls the video resolution and therefore can have a large impact on
bandwidth usage. The higher the resolution, the larger the size of the frame and the higher the
network bandwidth required.
Table 2-1 provides the corresponding resolution for each setting.
If the video will be viewed on its own and on a reasonably large screen, a large image size setting may
look better. On the other hand, if the video is shown as a tile in a video wall, a smaller image size may
look as good and consume less bandwidth.
The default RTP Settings for connecting to an IP video stream
from the PT-Series HD are shown in the illustration. The RTP
Port and the Stream Name are used when establishing a
session from a client.
The connection string for each of the video streams are as
follows:
VIDEO 0 - rtsp://192.168.0.250:554/stream1/sensor1
VIDEO 1 - rtsp://192.168.0.250:554/stream2/sensor1
VIDEO 2 - rtsp://192.168.0.250:554/stream1/sensor2
VIDEO 3 - rtsp://192.168.0.250:554/stream2/sensor2
