13、（DMIF V1 Clause 10.2）1.1.1 Extension of DMIF V1 QoS Descriptor （DMIF V1 Clause 10.2.1）Two QoS Descriptors are defined in DMIF: one is used at the DMIF-Application Interface, another one is used at the DMIF-Network Interface. Both specify the “transport” Quality of Service for an individual Elementar

14、y Stream.Only the semantics of the QoS_Descriptor used at the DAI is specified at the DAI API.The exact syntax of the QoS_Descriptor used at the DNI and in the DMIF Default Signaling Protocol （DDSP） is specified in this ISO/IEC 14496-6 Amd1.DMIF enables the aggregation of multiple Elementary Streams

15、 each with its “transport” QoS into a single TransMux, and computes the aggregate “stream” QoS. DMIF then maps the “stream” QoS for a particular TransMux into specific “network” QoS. This is shown in Figure 1.Figure 1Transformations of the Media QoSIn MPEG-4 “total” QoS parameters for an individual Elementary Stream are transmitted as part of the ES_Descriptor as defined in MPEG-4 Systems ISO/IEC 14496-1.
