This amendment defines two profiles for D-Cinema usage referred to in this standard as 2K and 4K. 6 MXF Mapping Constraints The

28、 D-Cinema application shall use only frame-based wrapping as defined in SMPTE 422M. There shall only be one picture essence track in the MXF file as defined in SMPTE 429-3. 6.1 KLV Coding Constraints The KLV coding structure is defined in SMPTE 422M section 5. This section defines specific values fo

35、.4 Essence Descriptors This section gives guidance in the use of MXF descriptors for use with this application specification. MXF files conforming to this specification shall use the RGBA Picture Essence Descriptor defined in SMPTE 377M together with the JPEG 2000 Picture Sub Descriptor defined in S

36、MPTE 422M. The identification of the picture components is provided through the values of the PixelLayout Item of the RGBA Picture Essence Descriptor as defined in SMPTE 377M Annex E2.46. The DCDM color components X, Y and Z shall be coded respectively using the hexadecimal code values D8h, D9h and

37、DAh. NOTE These values represent the ISO 7-bit character codes for the letters: X, Y and Z with the most significant bit of each byte set to 1. This distinguishes the DCDM color components from the X, Y and Z character values already defined in SMPTE 377M Annex E 2.46. Other picture essence sub-desc

38、riptors may be added to provide additional description of D-Cinema pictures. 6.4.1 RGBA Picture Essence Descriptor (Informative) Table 4 below illustrates the RGBA Picture Essence Descriptor fields that should be used in D-Cinema applications. For simplicity and readability, not all columns defined

39、in SMPTE 377M are shown in the table. Designers should note that the values given here are for guidance only and should not be used verbatim. NOTE The RGBA Picture Essence Descriptor includes all the properties from the File Descriptor, the Generic Picture Essence Descriptor and the RGBA Picture Ess

40、ence Descriptor as defined in SMPTE 377M. Those properties that are for MXF management or are optional are not shown in table 4 below except where useful benefit is gained. In particular, Table 4 does not define the set Key value nor its Length field, as these are defined in SMPTE 377M. For clarity,

41、 not all columns of the descriptor are shown in Table 4, particularly the Local Tag, UL Designator, Req and Meaning columns. Please refer to SMPTE 377M Annex D for these values.
