Figure 32:Web broadcasting compression options
Lossless
compression
Lossless compression compresses the images
being broadcast without reducing image
quality. Increasing lossless compression can use
a considerable amount of the video capture
workstation CPU resources.
The default lossless setting is 5. The range is 1
(Speed, the lowest lossless compression) to 9
(Compression, the highest lossless
compression).
Lossy
compression
Lossy compression compresses the images
being broadcast by reducing image quality.
Lossy compression is not as CPU intensive as
lossless compression.
The default lossy setting is 75. The range is 10
(Compression, the highest lossy compression
and lowest quality) to 100 (Quality, the lowest
lossy compression and the highest quality).
