A subscriber with a good network connection may not need or want the high-bitrate, high-resolution stream that would normally be requested based on the network connection speed. For example, the subscriber may be displaying the video on a small portion of its screen, in which case any resolution beyond that which is being displayed would be superfluous, or may have other limitations such as its CPU.

The bandwidth limitation does not affect the bandwidth of the entire stream, only that of the specific track you are attempting to limit. Currently, bandwidth limitations only apply to video. Bandwidths of audio and of data are not affected by this feature. |
The video bitrate can be limited temporarily if needed. This can be done on either the publisher side or the subscriber side, but is more typically requested by the subscriber. In other words, a subscriber uses the limit bandwidth feature to inform the Phenix streaming system that it can only use a certain number of bits per second.
