AfterUpSwitchBufferBandwidthRule is an emergency rule based on BufferBandwidthRule. It kicks in if the last fragment downloaded is higher quality than the previous one and it recommends a lower bitrate if the current quality is cleary unsustainable.

It works like the BufferBandwidthRule, only on a single fragment (the last downloaded) and only if that fragment is the first from a higher quality level. In addition to the BufferBandwidthRule, this rule will not kick in (will return a zero-confidence recommendation) if the bandwidth is above an acceptable level.

Public Properties

	Property		Defined By
		bufferFragmentsThreshold : Number The number of fragments in the buffer above which no lower bitrates are recomended. For example, assume the bandwidth has a value of 3000 kbps and the actual bitrate is 5000 kbps. If the number of fragments in the buffer is below the threshold, the rule will recommend 3000 kbps; otherwise, it will recommend 5000 kbps	BufferBandwidthRule
		constructor : Object A reference to the class object or constructor function for a given object instance.	Object
		metricRepository : MetricRepository [read-only] The metric repository.	RuleBase
		minBandwidthToBitrateRatio : Number The minimum acceptable value of the bandwidth / bitrate fraction. This is taken into consideration only if the bufferFragmentsThreshold constraint is not satisfied.	AfterUpSwitchBufferBandwidthRule
		weights : Vector.<Number> [read-only] The weights of the fragments (first values are the weights of the most recent fragments	BandwidthRule
