{{docname|STBService:1.4 Service Object}} {{appdate|August 2015}} Added objects for Service Monitoring of Events Table to describe the set of profiles and levels combinations supported by the STB when MPEG4 Part 10 is used as video standard. {{keys}} The table MUST include a distinct entry for each supported combination of these parameters. Maximum number of event log entries that the STB is able to record for a MainStream object instance. 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. Enables or disables the collection of the events for all main streams. When the collection of events is enabled, any previously collected events are discarded and the collection of new events begins immediately. Enables or disables collection of Total and Sample statistics and events for this object instance. The collection of events requires the value of this parameter to be {{true}} and the value of the {{param|##.ServiceMonitoring.EventCollectionEnable}} to be {{true}}. Total and Sample statistics and event collection status for this object instance. {{enum}} The {{enum|Error}} value MAY be used by the CPE to indicate a locally defined error condition. Time based UUID {{bibref|RFC4122|Section 4.2}} that is the identifier for the associated {{param|AVStream}} parameter when available to the device. This object represents the log entries of events recorded by the MainStream object instance. When the number of log entries in the EventLog exceeds the value of the {{param|###.Capabilities.ServiceMonitoring.MaxMainStreamEventLogEntries}} parameter, the Entry object with the lowest SequenceNumber value is replaced by the new EventLog Entry object. Log entries are persisted across reboots of the CPE. When set to true, clears the events from the event log and the value of {{param|Entry.{i}.SequenceNumber}} parameter is reset to the parameter's minimum value. {{numentries}} This object represents an entry (e.g., start session, channel change) in the event log. The sequence number of the event within the EventLog. This parameter is incremented by one (1) for each entry within the EventLog. When the value of the parameter exceeds the maximium range, the lowest value of this parameter that is not contained in current EventLog entries is used. Type of the event. The values for this parameter are vendor specific. Timestamp of the event. {{numentries}} This object represents an instance of a parameter that is associated with the Entry object Instance. Name of the parameter (vendor-specific). Value of the parameter.
