Metric and Dimensions Dictionary

MediaMelon utilizes its proprietary SDK to meticulously collect comprehensive data, facilitating the creation of a robust set of metrics for video analytics.

Within our framework, a set of universally recognized metrics is consistently accessible across all dimensions, while certain metrics are exclusively relevant to specific dimensions. The tabular presentation encompasses both the metric values employed in the API and the user-friendly labels integrated into the SmartSight Graphical User Interface (GUI).

It is worth noting that the majority of these metrics remain accessible for all video sessions.

Video related metrics and dimensions

Metrics

Metric Name	Metric (API)	Description
Attempts	attempts	Number of actions to play content, recorded when an ONLOAD event is received from the player (e.g., user presses PLAY).
Views	views	Ongoing Play events over the selected time period. Typically exceeds the number of Play events, as it tracks continuous activity rather than just successful starts.
Video Startup Failure(Startup Failure)	failurerate	Defines how many times or how often playback attempts are terminated during video startup before the first video frame is shown, excluding Business Exceptions.
Video Durations	totalduration	Total duration of video
Total Startup Failures	totalstartupfailure	Number of sessions where video playback did not start
Concurrent Sessions	concurviewavg	Number of ongoing playback sessions
Unique Viewers	uniqueviewercount	The number of distinct users on specifc devices who initiated at least one Play event over the selected time period, regardless of the number of Views or Attempts. The users are calculated using the subscriberid , deviceid ( if available) and user agent details.
Unique Subscribers	uniquesubscribercount	Unique number of subscriberids who initiated at least one Play event over the selected time period, regardless of the number of Views or Attempts.
Plays	viewercount	Number of playback attempts resulting in the first frame of video being displayed to the user.
Ended Plays	endedplays	Number of plays that ended during selected interval
Watchtime	watchtime	Total time spent in viewing the video , including buffering time, ad view time , time spent in seeking. It excludes the time spent in a paused state.
Playtime	playdur	Total duration spent viewing content, including buffering events, excluding ad plays, and accounting for seek behavior.
Traffic	cbrsize	Volume of data downloaded by customers during a session, aggregated over the selected time range.
Average Plays / Viewer	playperunique	Average number of video playback sessions per unique viewer
Average Playtime / Viewer	playtimeperunique	Average time watched per unique viewer
Fatal Errors	fatalerrors	Total number of fatal errors that prevent video playback, excluding Business Exceptions (included in PFP calculation).
Errors	erros	Total number of errors encountered during playback Attempts, including both fatal and non-fatal errors (e.g., Business Exceptions, technical issues).
Business Error Rate(BER)	businesserrorpc	Percentage of playback Attempts marked as Business Exceptions, which are excluded from Video Startup Failures and PFP calculations. Formula: BER = Be/ Se × 100 Where: Be = Total number of Business Exception errors Se= Total number of ended sessions
Playback Failure Precentage (PFP)	fatalerrorpc	Percentage of playback Attempts that result in fatal errors, preventing the video from playing (includes Startup Failures and other critical failures, excluding Business Exceptions).
Startup Delay	latency	Average value for the time taken for the first frame of video to be displayed after a user clicks “play” (includes auto-start or auto-play scenarios).
Rebuffering Ratio	bufferingratio	Percentage of total watchtime spent buffering, including Startup Delay. Formula: Buffering Ratio = Tb/Tw × 100 Where: Tb = Total buffering time (seconds) Tw = Total watchtime (seconds) Example: For a 60-minute Playtime with a 5% Buffering Ratio, 3 minutes are spent on buffering
Rebuffering Time	sumbuffwait	Percentage of total Playtime spent buffering, including Startup Delay. Formula: Buffering Ratio = (Tb + Tsd)/Tp × 100 Where: Tb = Total buffering time (seconds) Tsd = Startup Delay (seconds) Tp = Total Playtime (seconds) Example: For a 60-minute Playtime with a 5% Buffering Ratio, 3 minutes are spent on buffering and Startup Delay.
Rebuffering Wait Count	buffcount	Total number of times a session experiences buffering events during playback. Average Buffering Wait Count: Avg BWC = BwS Where: Bw = Total Buffering Wait Count across all sessions S = Total number of sessions
Connection Induced Rebuffering Ratio (CIRR)	bufferingratiocirr	Proportion of time spent buffering due to network issues relative to total watch time. Formula: CIRR = Tb /Tw *100 Where: Tb = Total buffering time caused by network issues (seconds) Tw= Total watch time (seconds)
Video Rebuffering Ratio (VRT)	bufferingratiovrt	Percentage of time (in seconds) after a user initiates seeking until the video begins playing again. Formula: VRT = Tr/Tw × 100 Where: Tr = Buffering time from seek completion to playback resumption (seconds) Ts = Total watchtime (seconds)
Exit Before Video Start (EBVS)	startupabandonmentrate	Measures the number of playback attempts that terminated before the video started playing (i.e., before the first frame is displayed).
VDS Active	isvdsactive	Total time where Audio for accessibility support was switched on
Subtitle Active	issubtitleactive	Total time where subtitles were switched on
Q Metric	qualityofexperience	An overall score (0-100) measuring user experience during video playback, factoring in latency and buffering penalties, adjusted by a session factor. Formula: Q = Sf × (1 - Wl × Pl) × (1 - Wb × Pb) × 100 Where: Pl = 1 - e-kl × L = Latency penalty Pb = 1 - e-kb × B = Buffering penalty Wl = Weight for latency penalty Wb = Weight for buffering penalty kl = Latency decay constant kb = Buffering decay constant L = Latency (e.g., Startup Delay in seconds) B = Buffering Ratio Sf = Session factor (context-specific multiplier)
Smoothness Score	smoothnessscore	A score (0-100) indicating playback smoothness, based on the frequency of buffering events and the buffering ratio. Formula: S = 1√(1 + (Bw / k)2) × 50 + e-kb × B × 50 Where: Bw = Buffering Wait Count (number of buffering events) B = Buffering Ratio k = Scaling constant for buffering wait count kb = Buffering decay constant
Signal Strength	signalstrength	Average WiFi signal strength
Wifi Data Rate	wifidatarate	WiFi connection max data rate
Wifi SSID	wifissid	WiFi Service Set Identifier (SSID)
