This is the dvrescue XML Schema. A dvrescue XML stores information about the metadata, continuity, errors, and qualities of a DV data stream. More information about the DV stream can be found within http://web.archive.org/web/20060927044735/http://www.smpte.org/smpte_store/standards/pdf/s314m.pdf. A media element refers to an input to dvrescue, commonly a file which includes dv data or a piped input. Reference to the original file path. Format of the file, for example DV, AVI, MPEG-4. File size, in bytes. As the qualities of a dv stream can change from frame to frame, the frames element groups together frames of like qualities. If a dv frame contains a specific quality that is different than that of the previous frame (such as a change from 4/3 aspect ratio to 16/9 or a change from 48000 Hz audio to 32000 Hz audio), then a new frames element will start. String representing the interlacement pattern of the frame. Options are: T: top, TT: top field only, B: bottom, BB: bottom field only, P: progressive Frame count within the current frames sequence. Presentation timestamp for start of sequence. Presentation timestamp for end of sequence. Dimensions of frame represented as width x height in pixels. Frame rate. Chroma subsampling value represented in three part ratio notation. Frame aspect ratio represented in fractional notation. Frame audio rate represented in full integer notation. Number of audio channels, between 0-8. DV25: 0-2 DV50: 0-4 DV100: 0-8 Values of 'y' and 'n' indicate whether there is or is not the presence of EIA-608 closed captioning packs with the VAUX section of the DV frames. A frame element holds notable information about frames that have been identified to include errors. The number of the DIF sequence within the frame starting from zero. Position (byte offset) of the frame. Presentation timestamp for frame element. Timecode. Boolean that indicates if timecode is repeating. Boolean that indicates if timecode is non-consecutive. Recorded Date Time. Boolean that indicates if recorded date time is repeating. Boolean that indicates if recorded date time is non-consecutive. Recording start. Recording end. Arbitrary data. Boolean that indicates if arbitrary data is repeating. Boolean that indicates if arbitrary data is non-consecutive. A value of 'mismatch' indicates that a EIA-608 closed captioning pack is present within the VAUX section of the frame, but that at least one of the contained captioning values fails its parity check. The number of the DIF sequence within the frame starting from zero. An NTSC DV25 frame will have ten DIF sequences (0-9) and a PAL DV25 frame will have twelve (12) DIF sequences (0-11). Documents a type of non-zero STA value present in the frame (see table 26 of s314m). For convenience: 0 = No error, what a nice DV macroblock. 2 = Replaced a macroblock with the one of the same position of the previous frame (guaranteed continuity). 4 = Replaced a macroblock with the one of the same position of the next frame (guaranteed continuity). 6 = A concealment method is used but not specified (guaranteed continuity). 7 = Error with an error code within the macro block. O_O 10 = Same as 2 but continuity is not guaranteed. 12 = Same as 4 but continuity is not guaranteed. 14 = Same as 6 but continuity is not guaranteed. 15 = Error with unknown position. A count of this particular type of STA value within the frame or dseq. Since STA values only apply to video DIF blocks, the maximum value for a DV25 NTSC frame is 1350 (135 video-DIF-blocks * (10 DIF-sequences / NTSC-frame)) and the maximum value for a DV25 is 1620 (135 video-DIF-blocks * (12 DIF-sequences / PAL-frame)). A count of this particular type of STA value within the even-numbered DIF sequences of the frame. @n minus @n_even would provide the count of this particular type of STA value within the odd-numbered DIF sequences of the frame. A discrepancy between the counts within even and odd DIF sequences can indicate that the associated error is from the playback device of the source tape rather than damage to the source tape. The range is 0-675 for NTSC DV25 and 0-810 for PAL DV25. Documents the type of audio errors within the frame. 1 = An audio DIF block is filled with 0x8000 which indicates an invalid audio sample. A count of this particular type of audio error within the frame or DIF sequence number (dseq). The maximum value for a DV25 NTSC frame is 90 (9 audio-DIF-blocks * (10 DIF-sequences / NTSC-frame)) and the maximum value for a DV25 is 108 (9 audio-DIF-blocks * (12 DIF-sequences / PAL-frame)). A count of this particular type of audio error within the even-numbered DIF sequences of the frame. @n minus @n_even would provide the count of this particular type of audio error within the odd-numbered DIF sequences of the frame. A discrepancy between the counts within even and odd DIF sequences can indicate that the associated error is from the playback device of the source tape rather than damage to the source tape. The range is 0-45 for NTSC DV25 and 0-54 for PAL DV25.
