A value of -1 indicates no specific limit on the number of active streams.

A value of 0, while not strictly illegal, would indicate an STB that doesn't support AV streams, which is extremely unlikely.

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.

DVB Triplet [TS102034] that uniquely identifies the service in the service list database.

The DVB Triplet is a 12-byte string that is a concatenation of 4 hexadecimal characters for each of the following: Original Network Id, Transport Stream Id, Service Id. For example:

• OriginalNetworkId = 8442 = 0x20FA
• TransportStreamId = 4 = 0x0004
• ServiceId = 257 = 0x0101

-> DvbId = 20FA00040101

When set to true, identifies this as the preferred service for this logical channel and automatically sets Preferred to false for other services associated with this logical channel.

When set to false, cancels this service's preferred status and causes the service with the lowest BER (best received quality) to become the preferred service for this logical channel.

Whenever frequencies are re-scanned, all Preferred parameters are implicitly reset to false, i.e. a re-scan will always use the BER to determine preferred services, and will discard any past explicit overrides.

Enables or disables collection of Sample statistics.

When collection of Sample statistics is enabled, any stored samples are discarded, and the first sample interval begins immediately.

Indicates availability of Sample statistics. Enumeration of:

• Disabled (Collection is disabled)
• Enabled (Collection is enabled)
• Trigger (Collection is enabled and the ACS should now fetch the collected data)

The Trigger value is only used for triggering the ACS to fetch the collected data and can only be used when FetchSamples is in the range [1:ReportSamples].

The transition from Enabled -> Trigger -> Enabled MUST be instantaneous and so will result in only a single value change for notification purposes.

The sample interval in seconds. Each statistic is measured over this sample interval.

The STB MAY reject a request to set SampleInterval to less than Capabilities.ServiceMonitoring.MinSampleInterval.

Sample intervals MUST begin every SampleInterval seconds, with no delay between samples.

If SampleInterval is changed while collection of Sample statistics is enabled, any stored samples are discarded, and the first sample interval begins immediately.

For example, if ReportSamples is 24 and SampleInterval is 3600 (an hour), the STB can store up to a day's worth of samples for each statistic.

The number of samples that the STB can store and report for each statistic.

The STB MUST permit ReportSamples to be set to any value in the range from 1 to Capabilities.ServiceMonitoring.MaxReportSamples.

If ReportSamples is changed while collection of Sample statistics is enabled, the STB will truncate or extend its statistics buffers as appropriate, but statistics collection MUST NOT otherwise be affected.

For example, if ReportSamples is 24 and SampleInterval is 3600 (an hour), the STB can store up to a day's worth of samples for each statistic.

The number of event measurements of each applicable statistic that the STB is able to store for each sample interval.

The STB MUST permit EventsPerSampleInterval to be set to any value in the range from 1 to Capabilities.ServiceMonitoring.MaxEventsPerSampleInterval.

If EventsPerSampleInterval is changed while collection of Sample statistic is enabled, the STB will truncate or extend its event measurement buffers as appropriate, but event measurement collection MUST NOT otherwise be affected.

For example, if ReportSamples is 24 and SampleInterval is 3600 (an hour), and EventsPerSampleInterval is 60, the STB can store up 60 event measurements per hour, or in total 1440 event measurements per day.

If collection of Sample statistics is enabled and FetchSamples is in the range [1:ReportSamples] then SampleState MUST transition from Enabled -> Trigger -> Enabled on completion of every FetchSamples sample intervals. Otherwise, this transition MUST NOT occur.

For example, if ReportSamples is 25 and FetchSamples is 24, then the STB will store 25 values for each statistic and the above 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 ForceSample).

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 SampleInterval.

This time reference also determines when the SampleState Enabled -> Trigger -> Enabled transitions that are controlled by FetchSamples will occur. If collection of Sample statistics is enabled and FetchSamples is in the range [1:ReportSamples] then each such SampleState transition MUST occur at this reference time plus or minus an integer multiple of FetchSamples * SampleInterval (the fetch interval).

TimeReference is used only to set the "phase" of the sample and fetch intervals. The actual value of TimeReference can be arbitrarily far into the past or future.

If TimeReference 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 [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 TimeReference parameter was set to the Unknown Time value.

For example, if SampleInterval is 3600 (an hour) and if TimeReference 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, FetchSamples is 24, then the fetch interval is 86400 (a day) and SampleState Enabled -> Trigger -> Enabled transitions will occur every day at UTC midnight.

Note that, if TimeReference 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 SampleInterval). This is why TimeReference is defined in terms of when sample intervals complete rather than start.

When set to true, forces statistics for the current sample to be calculated and updated in the data model. Setting it to false has no effect. The value is not saved in device state and is always false when read.

If this is the first time that ForceSample has been set to true during the current sample interval, this MUST cause a new value to be added to each of the Sample statistics comma-separated list parameters, and the ReportEndTime and all SampleSeconds parameters MUST be updated accordingly.

If this is not the first time that ForceSample has been set to true during the current sample interval, then the new values that were added as described in the previous paragraph, and the ReportEndTime and all SampleSeconds parameters, MUST be updated accordingly.

Note that ForceSample just provides a sneak preview of the current sample. It does not create a new sample and it does not interfere with the sample interval schedule.

At the end of each sample interval, if ForceSample was set to true during the sample interval then the new values that were added as described above, and the ReportEndTime and all SampleSeconds parameters, will be updated accordingly. In other words, the partial sample data that was created when ForceSample was set to true will be updated one last time at the end of the sample interval.

The absolute time at which the sample interval for the last stored sample (for each statistic) ended.

If ForceSample has been used to force statistics for the current sample to be calculated and updated in the data model, then ReportEndTime MUST be updated to reflect the actual time over which stored data was collected.
