Streaming Tab; Image Quality; Adaptive Rate Control; Audio Port Number - Sony Ipela SNC-CH140 User Manual

Frame rate
Set the frame rate of the image.
Selectable frame rates are as follows:
1, 2, 3, 4, 5, 6, 8, 10, 15, 20, 25, 30 (fps)
"fps" is a unit indicating the number of frames
transmitted per second.
Configurable frame rates are as follows:
Image size (1280 × 1024)
Image 1

H.264

Bit rate
Set the bit rate of MPEG4 or H.264 image transmission
for a line. When the bit rate is set to a high level, better
image quality can be enjoyed.
Selectable bit rates are as follows:
64, 128, 256, 384, 512, 768, 1024, 1536, 2048, 3072,
4096, 5120, 6144, 7168, 8192 (kbps)
I-picture interval
Set the I-picture insertion interval.

Adaptive rate control

This function adjusts the frame rate and the bit rate
automatically so that the camera plays back a smooth
image to suit the connected computer environment. If
On is selected, the MPEG4 or H.264 image rate is
automatically adjusted.
Notes
• The actual frame rate and bit rate may be different
depending on the image size, shooting scene, or
network condition.
• When Adaptive rate control is set to On, the actual
frame rate and bit rate change within the range that
does not exceed the values set in Frame rate and Bit
rate.

Image quality

Set the JPEG image quality.
Selectable values are from Level 1 to Level 10.
When Level 10 is selected, the best image quality is
achieved.
Bandwidth control
Limits the network bandwidth for the JPEG image data
output from the camera.
Note
Audio may be interrupted depending on the selected
bandwidth. In this case, select a wider bandwidth.
OK/Cancel
See "Buttons common to every menu" on page 26.

Streaming Tab

Use this tab to set the items for the transmission by
unicast or multicast.
Unicast streaming
Specify the transmission port numbers of the MPEG4/
H.264 video data and audio data to be used when UDP
(Unicast) is selected from the Connection drop-down
list in the Other panel on the main viewer.
Video port number 1, 2
Specify the transmission port number of the MPEG4/
H.264 video data. It is initially set to 50000. Specify an
even number from 1024 to 65534. Two port numbers
(the number specified here and an odd number with 1
added to the specified number) are actually used for
video data communication and control.
The setting for Image 1 and Image 2 apply for Video port
number 1 and 2 respectively.

Audio port number

Specify the transmission port number of the audio data.
It is initially set to 50002. Specify an even number from
1024 to 65534. Two port numbers (the number specified
here and an odd number with 1 added to the specified
number) are used for audio data communication and
control.
Note
Specify different numbers for the video port number and
the audio port number.
