Maximum bit rate20 Mbps
Maximum buffer size (in 16384-bit units)2442 (about 2.66 seconds at maximum bit rate)
Interlaced EncodingYes

 

Generic Main Profile

A stream that complies with the algorithmic limitations of the main profile, but does not fit into one of the level specifications, will be assigned "MP" as its device conformance template string.

Complex Profile

Parameter Value
Template string"CP"
RemarksThe complex profile has no explicit limitations. It is used to enable all of the codec algorithms, usually for demonstration purposes.

 

The following tables list the parameters of the device conformance templates for the Windows Media Video 9 Image codec.

Video Image Level 1

Parameter Value
Template string"I1"
Maximum resolution352 x 288
Maximum frame rate30 fps
Maximum bit rate192 Kbps

Interlaced EncodingNo

 

Video Image Level 2

Parameter Value
Template string"I2"
Maximum resolution1024 x 768
Maximum frame rate30 fps
Maximum bit rate384 Kbps
Maximum buffer size (in 16384-bit units)77 (about 3.26 seconds at maximum bit rate)
Interlaced EncodingNo

 

Generic Video Image

A Video Image stream that does not fit into one of the level specifications will be assigned "I" as its device conformance template string.
