Description
Part 10 or
Advanced Video
Coding (AVC)
— Created to address a broad range of applications from
low bit rate to high bit rate and from low resolution such
as cell phones to high resolution such as broadcast.
— The Niagara SCX H.264 is baseline profile.
— MPEG-4, Part
2, or H.263
— Applies to situations where other conditions of the
applications, like network bandwidth or device size,
mandate low bit rate and low resolution.
— Examples of video applications for H.263 include cell
phones, some low-end video conferencing systems, and
surveillance systems.
— H.263 remains important for legacy handheld devices
that do not support H.264.
— H.263 – MP4
MPEG-4, Part
2, or H.263
— For situations where other conditions of the applications,
like network bandwidth or device size mandate low bit
rate and low resolution.
— Examples of video applications for H.263 include cell
phones, some low-end video conferencing systems, and
surveillance systems.
— H.263 remains important for legacy handheld devices
that do not support H.264.
NOTE: By default, the Niagara SCX H.263 uses Simple Profile unless you
select the Enable B Frames option. If you enable B frames, the resulting
stream becomes Advanced Simple Profile.
— H.263 – 3G2
Creates an H.263 stream stored in a 3G2 container.
— H.263 – 3GP
Creates an H.263 stream stored in a 3GPP container.
— MPEG4 – 3GP
— Exemplifies a multimedia container format defined by the
Third Generation Partnership Project (3GPP) for use on
3G mobile phones.
— It stores video streams such as MPEG-4 or H.264 and
audio streams such as AMR or AAC.
— The two defined standards for this format include:
1) 3GPP for GSM based mobile phones
2) 3GPP2 for CDMA based mobile phones
— Creates an H.263 stream stored in a 3GPP container.
— H.264 – 3G2
Creates an H.264 stream stored in a 3G2 container.
— H.264 – 3GP
Creates an H.264 stream stored in a 3GPP container.
 Set the frame rate and bit rate under the Video settings (Figure 92).
 The Enable B Frame option turns on or off the insertion of B frames in the
video stream.
