Question: In a Transparent end-to-end Packet-switched Streaming Service (PSS), how is the `Content_Switch_Time` utilized in reporting metrics to the PSS client over a resolution period?
Option 1: Each `Content_Switch_Time` value is reported individually as a separate 'Metric-Name' entry.
Option 2: All `Content_Switch_Time` values are summed up and reported as a single metric named 'TotalContentSwitchTime', alongside the count of events as 'NumberOfContentSwitchEvents'.
Option 3: The average `Content_Switch_Time` is calculated and reported as 'AverageContentSwitchTime' without any event count.
Option 4: `Content_Switch_Time` is not directly reported; instead, its inverse value is used to calculate a 'Streaming Efficiency' metric.
Explanation: This option correctly reflects the process described for handling `Content_Switch_Time` in the context of PSS. Summing up all `Content_Switch_Time` values over a resolution period and reporting this total, alongside the number of events (as 'NumberOfContentSwitchEvents'), aligns with efficient and informative metric reporting. This approach allows for comprehensive analysis of streaming service performance without overwhelming the client with individual event data.
