30、4 HELICAL-SCAN DIGITAL VIDEO CASSETTE RECORDING SYSTEM USING 12,65 mm (0,5 in) MAGNETIC TAPE FORMAT HD-D5 Part 1: VTR specifications 1 Scope This part of IEC 62330 specifies the content, format, and recording method of the data blocks containing HD compressed video data defined in part 2, audio, and

31、 associated data which form the helical records on 12,65 mm (0,5 in) tape in cassettes as specified in IEC 61835. In addition, this standard specifies the content, format, and recording method of the longitudinal record containing tracking information for the scanning head associated with the helica

32、l records, and also the longitudinal cue audio, and time and control code. One video channel of HD compressed video data and four independent audio channels are recorded in the digital format. Each of these channels is designed to be capable of independent editing. The HD compressed video data are d

40、 conditions: Temperature 20 C 1 C Relative humidity (50 2) % Barometric pressure from 86 kPa to 106 kPa Tape conditioning not less than 24 h Centre tape tension 0,31 N 0,05 N (see Annex A) 3.2 Reference tape Blank tape for reference recordings should be available from any source meeting the tape cha

41、racteristics as portrayed by this standard. 3.3 Calibration tape The calibration tapes meeting the requirements of 3.3.1 and Clause 4 should be available from manufacturers who produce DTTRs and players in accordance with this standard. 3.3.1 Record locations and dimensions Tolerances shown in Table

42、 1 will be reduced by 50 %. 3.3.2 Calibration signals Two sets of signals should be recorded on the calibration tape: a) Video: 100 % colour bars Audio: 1 kHz tone at 20 dB below full scale on each of audio channels Cue: 1 kHz tone at reference level; 10 kHz tone at reference level Page8 EN623301:20

43、04 b) A signal of constant recorded frequency (i.e. one-half the Nyquist frequency) shall be recorded only on tracks of field 0, segment 0 for the purpose of mechanical alignment. Recording level should conform to 6.6.3. 4 Video tape 4.1 Base The base material shall be polyester or equivalent. 4.2 W

44、idth The tape width shall be 12,650 mm 0,008 mm. The tape, covered with glass, is measured without tension at a minimum of five different positions along the tape using a calibrated comparator having an accuracy of 0,001 mm (1 m). The tape width is defined as the average of the five readings. 4.3 Wi

45、dth fluctuation Tape width fluctuation shall not exceed 5 m peak to peak. Measurement of tape width fluctuation shall be taken over a tape length of 900 mm. The value of tape width fluctuation shall be evaluated by measuring the tape width at 10 points, each separated by a distance of 100 mm. 4.4 Ta

46、pe thickness Two types of tape thickness shall be permitted by this standard. The first tape thickness shall be 10,2 m to 11,0 m (referred to as 11 m); the second tape thickness shall be 13,0 m to 14,0 m (referred to as 14 m). 4.5 Transmissivity Transmissivity shall be less than 5 %, measured over t

47、he range of wavelengths 800 nm to 900 nm. 4.6 Offset yield strength The offset yield strength shall be greater than 9 N for 11 m tape and 10 N for 14 m tape.
