Video-DSL Rate Prediction
Video-DSL Rate Prediction
The video-DSL rate prediction test
provides an innovative way to
understand the otherwise complicated
output of electrical and attenuation
measurements, and noise tests as they
relate to the capacity to transport IPTV
video over ADSL2+ circuits. This test
performs a series of loop-quality
measurements before predicting the
ADSL2+ data rate and Video-DSL rate.
Based on current loop conditions and user-defined technology, the
video-DSL rate prediction test shows you how many streams of standard
broadcast (SB) and high definition (HD) IPTV video streams the tested
circuit could reliably carry.
Configuring Video-DSL Rate Prediction
Parameters for auto test configuration are on the Video-DSL Rate
Prediction pane tabs.
To view the test configuration
tabs:
1. From the Video-DSL Rate
Prediction pane use the up/down
arrow keys to highlight Test
Configuration, and press
.
2. Press the F1, F2, or F3 key to view
the various tabs. To view any
available additional tabs, use the
function arrow keys on either side of the F1 and F3 keys.
