where:
* '''&lt;addr&gt;''' is the IP address of the service source (for Unicast) or IGMP  group (for Multicast).
* '''&lt;port&gt;''' is the associated TCP/UDP port.  If not specified, the STB is assumed to know and use an appropriate default port.
* '''&lt;trsp&gt;''' is the streaming transport protocol and MUST be one of the values in {{param|.Capabilities.FrontEnd.IP.StreamingTransportProtocols}}, which SHOULD be converted to lower-case. 
* '''&lt;strctrl&gt;''' is the streaming control protocol and MUST be one of the values in {{param|.Capabilities.FrontEnd.IP.StreamingControlProtocols}}.  If not specified, no streaming control protocol is to be used.
* '''&lt;trspctrl&gt;''' is the streaming transport control protocol and MUST be one of the values in {{param|.Capabilities.FrontEnd.IP.StreamingTransportControlProtocols}}.  If not specified, no streaming transport control protocol is to be used.
* '''&lt;muxtype&gt;''' is the multiplex type and MUST be one of the values in {{param|.Capabilities.FrontEnd.IP.MultiplexTypes}}.  This tells the STB which multiplex type to expect.  If not specified, the STB is assumed to know, or to be able to determine, the multiplex type.
Note that download protocols are not supported by the above syntax.  However, the specified syntax is just a baseline, and STBs MAY support an extended syntax.
Example of Multicast MPEG2-TS over RTP with no transport control:
* rtp://224.112.15.18:3257?StrCtrl=IGMP?MuxType=MPEG2-TS

Example of Unicast MPEG2-TS over UDP with RTSP transport control:

Example of Unicast raw AV over RTP with RTCP control and RTSP transport control:
* rtp://174.146.35.12:3257?StrCtrl=RTSP?StrTrspCtrl=RTCP?MuxType=None
If a {{object|.ServiceMonitoring.MainStream}} instance with ''ServiceType'' = ''IP'' or ''IPTV'' (or ''VoD'' if the URI accesses a VoD service) is currently enabled, the STB MUST ensure that performance data for this service is collected in that instance.

    <object name="STBService.{i}.ServiceMonitoring." access="readOnly" minEntries="1" maxEntries="1">
      <description>Contains statistics relating to the QoS / QoE of Main AV streams. These statistics are broken down into categories, e.g. de-jittering and RTP, and for each category there are two types of statistics:
* '''Total''' statistics, which count the number of occurrences of something.
* '''Sample''' statistics, which are measured over a sample interval, and are made available to the ACS as a list of the most recent n samples.
Total statistics are always collected (collection cannot be disabled, but the values can be reset).
For Sample statistics, an STB uses a single sample interval and number of samples (n) for all {{object|MainStream}} instances.  The sample interval can be aligned with absolute time.
When Sample statistics collection is enabled, statistics collection MUST proceed regardless of whether there are any active Main AV streams.  For example, when the STB is in Standby mode, there will be no active Main AV streams, but sample intervals will continue to be timed as normal.
Refer to {{bibref|TR-135|I.3}} for non-normative explanation of the operation of the ''ServiceMonitoring'' object.</description>

For example, if {{param|ReportSamples}} is 25 and {{param}} is 24, then the STB will store 25 values for each statistic and the above {{param|SampleState}} transition will occur every 24 sample intervals, which means that the ACS could delay for up to two sample intervals before reading the stored values and would still not miss any samples (see also {{param|ForceSample}}).</description>

        <description>An absolute time reference in UTC to determine when sample intervals will complete.  Each sample interval MUST complete at this reference time plus or minus an integer multiple of {{param|SampleInterval}}.
This time reference also determines when the {{param|SampleState}} {{enum|Enabled|SampleState}} -&gt; {{enum|Trigger|SampleState}} -&gt; {{enum|Enabled|SampleState}} transitions that are controlled by {{param|FetchSamples}} will occur.  If collection of Sample statistics is enabled and {{param|FetchSamples}} is in the range [1:{{param|ReportSamples}}] then each such {{param|SampleState}} transition MUST occur at this reference time plus or minus an integer multiple of {{param|FetchSamples}} * {{param|SampleInterval}} (the fetch interval).
{{param}} is used only to set the "phase" of the sample and fetch intervals.  The actual value of {{param}} can be arbitrarily far into the past or future.
If {{param}} is changed while collection of Sample statistics is enabled, any stored samples are discarded, and the first sample interval begins immediately.
The Unknown Time value defined in {{bibref|TR-106a1}} indicates that no particular time reference is specified.  That is, the STB MAY locally choose the time reference, and is required only to adhere to the specified sample and fetch intervals.
If absolute time is not available to the STB, its sample and fetch interval behavior MUST be the same as if the {{param}} parameter was set to the Unknown Time value.
For example, if {{param|SampleInterval}} is 3600 (an hour) and if {{param}} is set to UTC midnight on some day (in the past, present, or future) then sample intervals will complete on each UTC hour (00:00, 01:00, 02:00 etc).
If, in addition, {{param|FetchSamples}} is 24, then the fetch interval is 86400 (a day) and {{param|SampleState}} {{enum|Enabled|SampleState}} -&gt; {{enum|Trigger|SampleState}} -&gt; {{enum|Enabled|SampleState}} transitions will occur every day at UTC midnight.
Note that, if {{param}} is set to a time other than the Unknown Time, the first sample interval (which has to begin immediately) will almost certainly be shorter than {{param|SampleInterval}}).  This is why {{param}} is defined in terms of when sample intervals complete rather than start.</description>

It is up to the STB to determine which AV stream should be regarded as the Main AV stream for a given service type at any given time.  For example, if two active streams are associated with the same service type, the STB might prefer streams that are associated with an AV player, or if more than one stream is associated with an AV player, the STB might prefer a player that is outputting a DVI stream to a player that is outputting an RF stream.
Note that some parameters, e.g. {{param|.Components.FrontEnd.{i}.IP.ServiceConnect.URI}}, include requirements that restrict the STB's freedom to determine which AV stream should be regarded as the Main AV stream for a given service.</description>
