3.8.3 MPEG4/QQVGA
Video Type:
It’s MPEG4 mode in this profile.
Resolution:
It’s QQVGA mode (160x120) in this profile.
Bit 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 idea bit rate is between
64kbps and 384kbps. User can set the desired bit rate to match the limitation of bandwidth. For
VBR, user should choose the quantization level to set the video quality rather than bit rate.
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. User can set the
desired max frame rate versus video quality under the limited bandwidth.
Quality or Quantization level:
For CBR mode, user should define the bit rate of this profile.
For VBR mode, user should define the quantization level of this profile.
