MPEG-4 Settings
The AXIS 213 supports the following different MPEG-4 profiles and levels:
Profile@Level
Advanced Simple Profile @ Level 3
Advanced Simple Profile @ Level 5
Level 5 is preferred if there is enough bandwidth available, as the image quality of the
video stream will be better than if level 3 is used. The viewing client must support the
profile used for the video stream otherwise the MPEG-4 stream can not be viewed.
Note:
The Axis Media Control supports all the configuration possibilities available on this page.
The GOV structure can be set to either I or IP, which describes the type of images
included in the video stream, as well as their internal order. The IP-structure generally
sends the differences compared to the previous image and far fewer complete images,
so this method uses much less bandwidth than the I-structure. The I-structure gives
higher frame rates when using a high resolution, but requires more bandwidth.
The GOV length determines the sum total of P-images and I-images in a GOV. Setting
the GOV length to a high value saves considerably on bandwidth. However there may
be noticeable decay in the image at high values.
Note:
GOV = Group of VOPs
VOP = Video Object Plane
Video Object Plane = image
