This parameter is used by the STB to determine whether an aspect ratio conversion is required.
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, 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.
The number of samples that the STB can store and report for each statistic.
The STB MUST permit {{param}} to be set to any value in the range from 1 to {{param|.Capabilities.ServiceMonitoring.MaxReportSamples}}.
If {{param}} 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 {{param}} is 24 and {{param|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 {{param}} to be set to any value in the range from 1 to {{param|.Capabilities.ServiceMonitoring.MaxEventsPerSampleInterval}}.
If {{param}} 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 {{param|ReportSamples}} is 24 and {{param|SampleInterval}} is 3600 (an hour), and {{param}} is 60, the STB can store up 60 event measurements per hour, or in total 1440 event measurements per day.

Each entry is a colon separated list of time periods (in milliseconds) between the instant of transmitting TCP SYN (the three way handshake) prior to first HTTP message, and receiving the last HTTP message carrying the information.
A comma separates measurements made in different sample intervals, while a colon separates individual measurements within a specific sample interval.
If no PortalResponse measurements were made during a specific sample interval then this MUST be represented by an empty string.
Example: ,837:453:1234,759,,,923:698,,,1284
Here there were no measurements during first sample interval, three during the second, one during the third, etc.
The statistics values in this list MUST be in time order, with the oldest one first and the most recent one last. This applies both to sample intervals and to individual measurements during a specific sample interval. {{nopattern}}
