System will determine the average audio level (to confirm that the average level is above the user specified threshold for this test), and look for a dropout below a silence threshold, with the release ratio of the waveform being at or below the user specified threshold for at least the user specified dropout time. Option 1 (Dropout With Return to Audio): The user defines the minimum and maximum amount of time that a dropout should occur before the Verification Unit reports an event. Additionally, the user defines the attack and release ratios of the audio surrounding the dropout, since dropouts are normally a squared-like pattern in the time domain. Additionally, the user can define the average audio level that must occur above the dropout, to ensure that only dropouts that would be noticed by the listener are reported. [see example image 1] Option 2 (Dropout Without Return to Audio): It is possible that audio is not resumed after a dropout, the user can select this option to look for dropouts that never recover. The same user inputs are used, although the attack ratio is not taken into account. [see example image 2] If attack and release ratio are not specified by the user, the vendor test should assume a viable attack and release ratio to use to find the dropout. basebandobjectiveaudiodigital drop-outanalogue drop-outaudio10:39:00:00 - 10:39:04:00 audio drop-out type 1 (with return to audio) found in audio with PID 1.

In the frequency domain, the system will seek out single tone audio, either at a specific frequence (such as 440 Hz) or at any frequency. The system will also seek out known test patterns, including "left ident" test tone, in which one channel periodically drops to silence. Optionally, aditional test patterns (such as GLITS and BLITS) may be detected.This test can be used to detect tones during programme material i.e. where they are not wanted.

A movie designed for a cinema screen will often have black bars at the top and bottom when shown on a 16:9 television screen or a 4:3 archive programme will have black bars left and right when shown on a 16:9 screen. Other black bars can be caused by picture shifts caused by timing errors.Used in Checks, the system shall report the presence of black bars in the video essence with size and duration beyond the specified input thresholds. Optionally the system may report time intervals and bar size where thresholds are exceeded. Used in Reports, the system shall report a sequence of time intervals where black bars appear regardless of their size and duration.The black bars meant here refer to black bars at the edges of the picture, which occur mostly on viewing or converting 4:3 material in 16:9 frames and viewing 16:9 material in 4:3 frames. But they may also constitute blanking errors. Note: "blanking errors" refer to the situation where blanking/VBI/VITC is "encroaching" into what should be the visible picture area.

Digital tape dropouts are visible artefacts which occur within the digital tape read process and manifest themselves when head problems or tape overuse cause the error correction of the VTR to create short term failures for parts of frames. The visual effect is the appearance of impairments, such as alternating lines in a block, duplicated block areas, arrays of pixels within a block area, and random portions of blocks with changed luminance or chrominance within one or multiple consecutive frames. The appearance of those blocks as well as the spatiotemporal pattern of those blocks strongly depends on the kind of tape, such as DIGI-Beta, IMX, HDCAM, DV, D1, D2, D3 and D5.basebandsubjectivevideodigital video tape dropoutdigital hitsdigital tape hitsvideoDigital Video Tape Dropouts present at 00:00:00:23 - 00:00:00:26DigitalTapeDropoutMinimumAreaMinimum total impaired area expressed as a percentage of the total frame areafalserequiredrequiredreal number%decimal with 1 fractional digitDigitalTapeDropoutMinimumDurationTime threshold (before QC event is created)falseoptionaloptional0integermsdecimalDigitalTapeDropoutDetectedDigital tape dropouts were detectedtruenot applicablerequired{true,false}boolean{true,false}DigitalTapeDropoutAreaTotal impaired area expressed as a percentage of the total frame areatrueoptionaloptionalreal numberdecimal with 1 fractional digitDigitalTapeDropoutDurationTotal duration of impaired segments.falseoptionaloptionalintegermsdecimal2.02.0enEssence DurationSMPTE ST 377Expected Video DurationDuration, Mismatch37802578https://qc.ebu.io/items/0040F/versions/2-0/image/icon/large/13585https://qc.ebu.io/items/0040F/versions/2-0/image/icon/small/37805256https://qc.ebu.io/items/0040F/versions/2-0/image/card/large/278386https://qc.ebu.io/items/0040F/versions/2-0/image/card/small/0040FVideo Duration2.0activecheck reportSystem shall check the duration of the video essence by checking the video bitstream.

MXF for example has a field "duration" that more precisely counts the number of edit units (for D10 this coincides with video frames), the wrapper also contains the framerate so it is possible in this case to calculate our wanted duration with a simple multiplication. Wrappers can sometimes contain wrong information leading to a wrong duration. A playable bitstream level MUST contain the information necessary to calculate our duration. If it is playable there is a way to establish the duration. Bitstream is the layer where the duration can be determined more reliably. It can be calculated in several ways depending on the format of the coding, but our specs don't want to enter into these details. For most of the cases also a crosscheck between audio and video duration is feasible and probably useful! While systems should strive to report audio errors in relation to the relative video time (frames), it is understood that this may not always be possible, and in some cases, audio errors could be reported in HRS:MIN:SEC.MSC relative to a start time of zero. crosscheckabsoluteformatdurationrun timeplaytimevideoEBU QC Test Item 0040FEBU QC Test Item 0040WThe video duration signalled in the metadata (00:02:30:00) is NOT the same as the one calculated based on the video frames in the bitstream (00:01:30:01).VideoDurationWrapperReportedValue from 0040WfalserequiredrequiredintegerFramesVideoDurationBitstreamReportedValue from 0040FfalserequiredrequiredintegerFramesVideoDurationCrosscheckMissmatchReports a missmatch between calculated video durationand the signalled video duration in the bitstream and the wrapper.falsenot applicablerequired{true,false}boolean{true,false}1.01.02.0enField Order ArtefactsVisible ErrorsField Order as ExpectedMotion Errors, Field Mismatch30002232https://qc.ebu.io/items/0041B/versions/1-0/image/icon/large/13585https://qc.ebu.io/items/0041B/versions/1-0/image/icon/small/37805256https://qc.ebu.io/items/0041B/versions/1-0/image/card/large/278386https://qc.ebu.io/items/0041B/versions/1-0/image/card/small/0041BVideo Field Order2.0activecheck reportSystem shall attempt to identify incorrect field order at the baseband level.This test item is to identify reversed field order artefacts which can appear as motion judder.

For example, the tolerance allowed by EBU R103 is calculated as ±5% of "Expected Range" in code values. For and 8 bit signal, the Expected Range is 16-235. The tolerance is therefore 5% of 220 = 11. The 8bit minimum is 16 - 11 = code value 5 and the maximum is 235 + 11 = code value 246. In the case of a 10 bit signal the Expected Range is 64-940 making the tolerance ±5% of 877 = 43.8 which is rounded to ± 44.In Checks the system shall check for and may optionally report, video signal values lying outside the acceptable range.

Subjective factors (edge steepness, noisyness, texturedness) may influence perceived sharpness of upscaled frames with a certain signal/content resolution. The focus may not be identical over the entire frame, e.g. image areas with relevant image content are best focused, other areas like the background can be out of focus. In this case best focused image areas are relevant for sharpness determination by humans or machines. The implementation of video upscaling detection is vendor specific.

The Origin Parameter for the File Package indicates how much stored essence exists before or after the zero point of the track. The Origin value gives the start point along the stored essence track measured in Edit Units. In the Material Package the Origin always shall be zero but could be set wrong.In Checks, the system shall detect the Origin parameter in the MXF timeline track and compare it with the Origin expected value provided by the user. Optionally it may report the value of the Origin parameter. In Reports, the system shall report the value of the Origin parameter. Common problem: often "target systems", such as MXF file readers and transcoders, have problems with Origin values other than "0". Examples of errors the target system may report are: - Picture could not be detected properly as the reference picture was not found; - Forward bottom reference field required for decoding this picture is missing. Solution: MPEG re-encoding typically is needed, at least for the part of the frames in the precharge & rollout. Just rewrapping the files does not correct the error and is thus not sufficient.

False detections may occure as clicks and crackles are also used for creative sound design. Audio clicks are short duration audio artefacts caused in digital systems by hardware/software problems such as buffer under-run/overflow or synchronisation issues. When present inside an audio file they are usually generated because of a defective or critical recording chain.

Timestamps are not guaranteed to be present in all situations, and if not present, this test should not be performed. If both PES & SEI messages are present for timestamps and the container does not specify which one should take precedence, both should be checked for discontinuity. Discontinuities typically happen when the frame count increments by one and one of the following situations occurs: a) timestamp increments by more than one frame; b) timestamp remains constant or decrements in any manner. MPEG-2 does allow for direct encoding from tape to transmit the LTC in the time_code section of the gop_header. If this is present, it could be used to check for discontinuities.

HoH captions may be edited or contain additional information text (such as action labels). The variation tolerance input variable defines a threshold for acceptable variation from the audio. Variation is measured using the Word Error Rate formula, applied to the duration of the audio and expressed as a decimal (not to be be confused with WER expressed as percentage for the whole file). The mismatched HoH captions tolerance input variable specifies a percentage of HoH caption blocks that exceeded the tolerated variation. Note that this Test does not check for missing HOH captions. It should be used alongside 0248B [https://qc.ebu.io/items/0248B/].Used in Checks, the system shall detect Hard of Hearing (HoH) captions where the text deviates from the temporally corresponding dialogue by more than the defined Text Variation tolerance, and whether the ratio of such detected HoH caption blocks exceeds the tolerated ratio of mismatched HoH caption blocks.

Used as a Report, the system shall report the time intervals of captions/subtitles which are shifted more than N seconds before or after the location where the corresponding dialogue is spoken in the audio.This kind of issue is most often seen when "live-captioned" material is re-purposed for the web, etc. Live-captioned content is typically delayed between 7 and 12 seconds behind the spoken word. Another example of this issue is where the entire subtitle is consistently shifted by a fixed amount. This could be the result of an edit which has caused the media to contain extra content not accounted for in the timing of the closed captions. For example, a 10-second test slate / identification added to the beginning of the media would cause all subtitles to be displayed 10 seconds too early.basebandsubjectivetext-dataclosed captionshard of hearing subtitlestranslation subtitlesaudioaccess servicetextInput: "ServiceChannelAllocation" = 4a 1,2 "CaptionsReference" = "foo.xml" "OutOfSyncCaptionTotalDurationThreshold" = 1 second "OutOfSyncCaptionShiftToleranceBefore" = 1 second "OutOfSyncCaptionShiftToleranceAfter" = 1 second Output: "CheckResult" = false "OutOfSyncCaptionSegment" from 00:00:00:00 to 00:30:00:00 --> "OutOfSyncCaptionShiftAmount" = -10.0 seconds Used as a Check.

Maximum Duration: 7 seconds per subtitle eventhttps://www.bbc.co.uk/accessibility/forproducts/guides/subtitles/BBC Subtitles GuidelinesBased on the recommended rate of 160-180 words per minute, you should aim to leave a subtitle on screen for a minimum period of around 0.3 seconds per word (e.g. 1.2 seconds for a 4-word subtitle). However, timings are ultimately an editorial decision that depends on other considerations, such as the speed of speech, text editing and shot synchronisation. When assessing the amount of time that a subtitle needs to remain on the screen, think about much more than the number of words on the screen; this would be an unacceptably crude approach.Based on Theatrical, Streaming, Broadcast examples, minimum expected duration for single word subtitle instance is: 0.3 seconds (BBC) 0.834 seconds @ 24fps (Video On Demand) 0.625 seconds @ 24fps (Theatrical)Examples above for common delivery destinations.
