This article was previously published under Q186867 SUMMARY This article discusses the maximum video frame rate per
second (fps) that the following versions of NetMeeting can transmit and
receive:
- Microsoft NetMeeting versions 2.0, 2.1, 2.1 Service Pack 1,
3.01 for Windows 95
- Microsoft NetMeeting versions 2.0, 2.1, 2.1 Service Pack 1,
3.01 for Windows NT Workstation 4.0
- Microsoft NetMeeting versions 2.0, 2.1, 3.01 for Windows 98
MORE INFORMATION NetMeeting sends and receives video at the maximum fps of
the lowest speed processor and the capturing, sending and receiving hardware of
the two computers in the session. The following versions of
NetMeeting can send and receive up to 30 fps on a computer with a Pentium Pro
and Pentium II processor (if the capturing, sending, and receiving hardware is
capable of 30 fps or greater): - Microsoft NetMeeting versions 2.1 Service Pack 1, 3.01 for
Windows 95
- Microsoft NetMeeting versions 2.1 Service Pack 1, 3.01 for
Windows 98
- Microsoft NetMeeting versions 2.1 Service Pack 1, 3.01 for
Windows NT Workstation 4.0
The following versions of NetMeeting can send and receive up to
17 fps: - NetMeeting versions 2.0, or 2.1 or earlier for Windows 95
or NT Workstation 4.0
Maximum FPS of NetMeeting 2.1 Service Pack 1 for Each Processor Use the following table to determine the maximum fps of
NetMeeting 2.1 Service Pack 1 for each processor. You can send video
in three different formats by using the Send Image Size option:
Large - common interchange format (CIF)
Medium - quarter common interchange format (QCIF)
Small - sub quarter common interchange format (SQCIF)
The actual fps may be less for your connection based on the
hardware, bandwidth, and the programs that are running on each computer:
Video
Processor format FPS
--------- ------ ---
486 SQCIF 7
QCIF 7
CIF 3
Pentium SQIF 15
QCIF 15
CIF 7
Pentium Pro SQCIF 30
-or- QCIF 30
Pentium II CIF 15
Notes: - Multiple-processor boards are not included in these
calculations.
- NetMeeting versions 2.0 and 2.1 or earlier can send and
receive up to 17 fps with similar hardware configurations.
Example 1 Computer A has a 486 processor and computer B has a Pentium
processor, the maximum frame rate that the two computers can send and receive
with QCIF is 7 fps. Example 2 Both computer A and computer B have Pentium processors, the
maximum frame rate that the two computers can send and receive with QCIF is 15
fps. Example 3 Computer A has a 486 processor and computer B has a Pentium
processor. If computer A sends video using CIF and computer B sends video with
SQCIF, computer A sends 3 fps with CIF and receives 7 fps of video with SQCIF.
Computer B receives 3 fps at CIF and sends 7 fps of video at SCQIF. Obtaining NetMeeting 2.1 Service Pack 1 To obtain NetMeeting 2.1 Service Pack 1, please visit either of
