Quality of service ranking and measurement methods for digital video broadcasting services delivered over broadband Internet protocol networks

This Recommendation specifies performance requirements and objective measuring methods of quality of service (QoS) for the delivery of digital video broadcasting services over broadband Internet protocol (IP) networks. The specified performance requirements are based on an IP QoS ranking at various levels, from “excellent” to “out-of-service”. They rely on the objective end-to-end measurement of the values of a small number of parameters on the delivered IP streams, performed at the consumer premises equipment and relayed back to the head-end. The recommended objective measurement methods and parameters are known to influence the QoS delivered to the user.
