  <dataType name="DiagnosticsState">
    <description>
      Indicates the availability of diagnostics data. Enumeration of:
      {{enum}}
      If the ACS sets the value of this parameter to {{enum|Requested}}, the CPE MUST initiate the corresponding diagnostic test. When writing, the only allowed values are {{enum|Requested}} and {{enum|Canceled}}. To ensure the use of the proper test parameters (the writable parameters in this object), the test parameters MUST be set, and any errors or inconsistencies in the test parameters MUST be detected, either prior to or at the same time as (in the same SetParameterValues) setting this parameter to {{enum|Requested}}.
      When requested, the CPE SHOULD wait until after completion of the communication session with the ACS before starting the diagnostic test.
      When the test is completed, the value of this parameter MUST be either {{enum|Complete}} (if the test completed successfully), or one of the ''Error'' values listed above.
      If the value of this parameter is anything other than {{enum|Complete}}, the values of the results parameters for this test are indeterminate.
      When the diagnostic initiated by the ACS is completed (successfully or not), but not if it is canceled for any reason, the CPE MUST establish a new connection to the ACS to allow the ACS to view the results, indicating the Event code ''8 DIAGNOSTICS COMPLETE'' in the Inform message.
      After the diagnostic is complete, the value of all result parameters (all read-only parameters in this object) MUST be retained by the CPE until either this diagnostic is run again, or the CPE reboots. After a reboot, if the CPE has not retained the result parameters from the most recent test, it MUST set the value of this parameter to {{enum|None}}.
      Modifying any of the writable parameters in this object except for this one MUST result in the value of this parameter being set to {{enum|None}}.
      While the test is in progress, modifying any of the writable parameters in this object except for this one MUST result in the test being terminated and the value of this parameter being set to {{enum|None}}.
      While the test is in progress, setting this parameter to {{enum|Requested}} (and possibly modifying other writable parameters in this object) MUST result in the test being terminated and then restarted using the current values of the test parameters.
      While the test is in progress, setting this parameter to {{enum|Canceled}} MUST result in the test being canceled and the value of this parameter being set to {{enum|None}}. If the CPE does not support the {{enum|Canceled}} value, it MUST return a SPV error with "Invalid Parameter value" (9007) to the ACS instead.

      The value ''maxval'' indicates that no data is available for this parameter.  In the unlikely event that the actual value of the statistic is ''maxval'', the CPE SHOULD return ''maxval - 1''.
      The actual value of the statistic might be greater than ''maxval''. Such values SHOULD wrap around through zero.

          Note that this is the strict maximum but, depending on the AV streams to be decoded, a given STB may not always have the resources to run all of these AV players, e.g. it might be able to decode one main picture and one PIP in standard definition, but just a main picture and no PIP in high definition.

        <description>
          RFC 3986 URI that  describes the service to connect to in the form:
          * &lt;trsp&gt;://&lt;addr&gt;:&lt;port&gt;?StrCtrl=&lt;strctrl&gt;?StrTrspCtrl=&lt;trspctrl&gt;?MuxType=&lt;muxtype&gt;
          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 Multicast MPEG2-TS over RTP with AL-FEC transport control:
          * rtp://224.112.15.18:3257?StrCtrl=IGMP?StrTrspCtrl=AL-FEC?MuxType=MPEG2-TS
          Example of Unicast MPEG2-TS over UDP with RTSP transport control:
          * udp://174.146.35.12:3257?StrCtrl=RTSP?MuxType=MPEG2-TS
          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.
          The value is not saved in device state.  The value when read is not specified and need not be the value that was most recently written.

        Records events and collects QoS / QoE related statistics for 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, even when the STB is not receiving any data, 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>
          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.

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.
