MPEG4/QQVGA
Video type:
It’s a MPEG4 mode in this profile.
Resolution:
It’s QQVGA mode (160x120) in this profile.
Rate Control:
Defines the rate control method of this profile. There are two options: Constant Bit Rate
(CBR) or Variable Bit Rate (VBR). For CBR, the video bit rate is between 24kbps and
320kbps. User can set the desired bit rate to match the limitation of bandwidth. For VBR,
user should choose the quality level to set the video quality rather than bit rate. The
quality level is between 1 and 100. The higher value is the better quality.
Max Frame Rate:
Defines the targeted frame rate of this profile. For example, set the frame rate to 15 fps,
then the image will be updated for 15 frames per second as possible. User need to set
reasonable max frame rate versus video quality under the limited bandwidth.
