5 Page iii Scope and Field of Application 1 INTRODUCTION This supplement describes ten new Transfer Syntaxes to embed High Efficiency Video Coding (HEVC) / H.5 Main Profile / Level 5.1, Main Profile / Level 5.1, Scalable Monochrome Profile / Level 5.1, Scalable Monochrome 1 Profile / Level 5.1, Scalable Monochrome 1 Profile / Level 5.1 and Scalable Main :: Profile / Level.1 encoded pixel data in DICOM. It does not introduce any new SOP Classes or IODs. HEVC allows two new major enhancements of the DICOM standards: 1) The improvement of ::0 content compression efficiency ) The improvement of the lossless content management IMPROVEMENT OF THE ::0 CONTENT COMPRESSION EFFICIENCY The use of video and still image data in the medical industry has increased and new technologies providing better colors or higher precision are available on the market. Meanwhile, the needs for reduced storage and media exchange cost remains important. To answer the related demand for higher ::0 compression efficiency, this supplement proposes to add the following profiles. Transfer Syntax HEVC/H.5 Main Profile /Level 5.1 will perform consistent with the ISO/IEC 0-:01 HEVC Main Profile at Level 5.1. This will enable the storage of video files with a resolution of 09x at 50Hz/0Hz. Transfer Syntax HEVC/H.5 Main Profile /Level 5.1 will perform consistent with the ISO/IEC 0- :01 HEVC Main Profile at Level 5.1. This will notably enable the storage of video files with a higher dynamic range and a wider gamut space and a resolution of 09x at 50Hz/0Hz. 3 IMPROVEMENT OF THE LOSSLESS CONTENT MANAGEMENT In this supplement, it is also proposed to include new profiles in order to offer a more efficient way to store lossless images. The targeted applications include using HEVC streams to store and exchange lossless images. The proposed profiles aim at the compression of Monochrome and :: images as these are the ones which usually require processing and/or storage in a lossless format. The proposed HEVC profiles for monochrome and :: lossless support are based on scalability to bring a new efficient way to share and manage lossless images within PACS, and between PACS and other facilities or other devices inside a facility. The proposed new format of lossless stream would be composed of a lossy light base (with possibly a high quality) and a lossless heavier complementary stream. By using the profiles introduced below, it is possible to manipulate the lossy and the lossless versions of images without any additional compression on the storage side. The proposed syntax would allow for a software encoding roughly times slower than JPEG and decoding of roughly the same speed as JPEG (please note that these numbers are given as indications and may vary depending on the implementation). The expected compression gains which can be expected when using the transfer syntaxes below compared to using transfer syntaxes with JPEG000 are of about 1% to % depending on the content. The reader should be reminded that these syntaxes are proposed for the extra features they bring rather than the raw compression efficiency they bring.

6 Page iv Transfer Syntaxes Lossless HEVC/H.5 Scalable Monochrome Profile /Level 5.1 and Lossy HEVC/H.5 Scalable Monochrome Profile /Level 5.1 will perform consistent with the ISO/IEC 0-:01 HEVC Scalable Monochrome Profile at Level 5.1 except for additional constraints on the enhancement layers of the coded bitstreams. This will enable the storage of monochrome sequences of still pictures with a resolution of 09x at 50Hz/0Hz in a lossless or lossy format comprising a detachable lossy and lighter version. Such content can typically be produced from CT scanners. Transfer Syntaxes Lossless HEVC/H.5 Scalable Monochrome 1 Profile /Level 5.1 and Lossy HEVC/H.5 Scalable Monochrome 1 Profile /Level 5.1 will perform consistent with the ISO/IEC 0- :01 HEVC Scalable Monochrome 1 Profile at Level 5.1 except for additional constraints on the enhancement layers of the coded bitstreams. This will enable the storage of high dynamic range monochrome sequences of still pictures with a resolution of 09x at 50Hz/0Hz in a lossless format comprising a detachable lossy and lighter version. Such content can typically be produced from CT scanners. Transfer Syntaxes Lossless HEVC/H.5 Scalable Monochrome 1 Profile /Level 5.1 and Lossy HEVC/H.5 Scalable Monochrome 1 Profile /Level 5.1 will perform consistent with the ISO/IEC 0- :01 HEVC Scalable Monochrome 1 Profile at Level 5.1 except for additional constraints on the enhancement layers of the coded bitstreams. This will enable the storage of high dynamic range monochrome sequences of still pictures with a resolution of 09x at 50Hz/0Hz in a lossless or lossy format comprising a detachable lossy and lighter version. Such content can typically be produced from CT scanners. Transfer Syntaxes Lossless HEVC/H.5 Scalable Main :: Profile /Level.1 and Lossy HEVC/H.5 Scalable Main :: Profile /Level.1 will perform consistent with the ISO/IEC 0-:01 HEVC Scalable Main :: Profile at Level.1 except for additional constraints on the enhancement layers of the coded bitstreams. This will enable the storage of RGB video files and sequences of still pictures with a resolution of 190x0 at 50Hz/0Hz in a lossless or lossy format comprising a detachable lossy and lighter version. Such content can typically be produced from CT scanners. The levels defined in this section are meant to constrain the maximum picture size but not the decoder buffer size contrary to what is written in the HEVC specifications. This follows the simple fact that when encoding a video in lossless mode, the compression rate cannot be guaranteed. It is important to note that media file format and media applications standards are usually not designed for monochrome or :: images. Planning for a future compatibility with such standard is therefore deemed unnecessary.

DICOM provides a mechanism for supporting the use of HEVC/H.5 Image Compression through the Encapsulated Format (see PS 3.3). Annex A defines a Transfer Syntax that references the HEVC/H.5 Standard. The use of the DICOM Encapsulated Format to support HEVC/H.5 compressed pixel data requires that the Data Elements that are related to the Pixel Data encoding (e.g., Photometric Interpretation, Samples per Pixel, Planar Configuration, Bits Allocated, Bits Stored, High Bit, Pixel Representation, Rows, Columns, etc.) shall contain values that are consistent with the characteristics of the compressed data stream, with some specific exceptions noted here. The Pixel Data characteristics included in the HEVC/H.5 bit stream shall be used to decode the compressed data stream Notes: 1. These requirements are specified in terms of consistency with what is encapsulated, rather than in terms of the uncompressed pixel data from which the compressed data stream may have been derived.. When decompressing, should the characteristics explicitly specified in the compressed data stream be inconsistent with those specified in the DICOM Data Elements, those explicitly specified in the compressed data stream should be used to control the decompression. The DICOM data elements, if inconsistent, can be regarded as suggestions as to the form in which an uncompressed Data Set might be encoded The requirements are: Planar Configuration (00,000) shall be 0 Samples per Pixel (00,000) shall be 3 Photometric Interpretation (00,000) shall be YBR_PARTIAL_0 Bits Allocated (00,00) shall be Bits Stored (00,01) shall be High Bit (00,0) shall be 7 Pixel Representation (00,03) shall be 0 The value of HEVC/H.5 sample aspect_ratio_idc shall be 1 in the encapsulated HEVC/H.5 bit stream if aspect_ratio_info_present_flag is 1. Pixel Aspect Ratio (00,003) shall be absent. This corresponds to a 'Sampling Aspect Ratio' (SAR) of 1:1. The values for Rows (00,00), Columns (00,0011), Cine Rate (001,000), and Frame Time (001,3) or Frame Time Vector (001,5) shall be compliant with the Main Profile / Level 5.1 of the HEVC/H.5 standard ([ISO/IEC 0-:01]) and restricted to a square pixel aspect ratio. 3 0 Notes: 1. The value of Planar Configuration (00,000) is irrelevant since the manner of encoding components is specified in the HEVC/H.5 standard, hence it is set to 0.. The limitation on rows and columns are to maximize interoperability between software environments and commonly available hardware HEVC/H.5 encoder/decoder implementations. Source pictures that have a lower value should be re-formatted by scaling and/or pixel padding prior to HEVC/H.5 encoding.

16 Page 3. The Frame Time (001,3) may be calculated from the frame rate of the acquiring camera. A frame rate of 9.97 frames per second corresponds to a frame time of ms.. The value of chroma_format_idc for this profile and level is equal to 1, indicating the usage of ::0 content. One fragment shall contain the whole HEVC/H.5 bit stream Note: If a video stream exceeds the maximum length of one fragment (approximately GB), it may be sent as multiple SOP Instances, but each SOP Instance will contain an independent and playable bit stream, and not depend on the encoded bit stream in other (previous) instances. The manner in which such separate instances are related is not specified in the standard, but mechanisms such as grouping into the same Series, and references to earlier instances using Referenced Image Sequence may be used. The container format for the video bitstream shall be MPEG- Transport Stream, a.k.a. MPEG-TS (see [ISO/IEC 131-1]) or MPEG-, a.k.a. MP container (see [ISO/IEC 19-1] and [ISO/IEC 19-1]). The PTS/DTS of the transport stream shall be used in the MPEG coding. Any audio components present within the bit stream shall be interleaved in either LPCM, AC-3, AAC, MP3 or MPEG-1 Layer II audio format and shall comply with the following restrictions: Table -X.

Notes: 1. The value of Planar Configuration (00,000) is irrelevant since the manner of encoding components is specified in the HEVC/H.5 standard, hence it is set to 0.. The limitation on rows and columns are to maximize interoperability between software environments and commonly available hardware HEVC/H.5 encoder/decoder implementations.

The value of chroma_format_idc for this profile and level is equal to 0, indicating the usage of :0:0 content. 5. The constraint over the value of cu_transquant_bypass_flag in the HEVC/H.5 bitstreams ensures that the HEVC compression is lossless and fully reversible at least for the highest temporal layer of the bitstream.. The constraints over vps_max_layers_minus1, slice_type, pred_mode_type and inter_layer_pred_enable_flag are added in order to reduce the complexity of the design for complying codecs. One fragment shall contain either all the Access Units necessary to decode at least one frame and at most a single key frame, or the Access Unit associated with the decoding of a single frame of a non-base layer. All the Access Units corresponding to the encoding of a temporal layer shall be contained in fragments located after those containing the Access Units corresponding to the encoding of a temporally lower layer. 3 Notes: 1. These last two requirements allow a simplified parsing of the DICOM data when performing a random access to a frame.. The fragments used for non-base layer hevc streams cannot be read without the parsing of their associated base-layer complementary fragments The Number of Frames (00,000) attribute shall be equal to the number of frames associated with nuh_layer_id equal to 0. The Basic Offset Table item, when associated to a value, shall contain indexes referring to all the frames present in the stream. When the Basic Offset Table is associated to a value, there shall be one Basic Offset value from the Basic Offset Table per frame associated with a nuh_layer_id greater than 0. Note: The frames associated with nuh_layer_id not equal to 0 are enhancement of the others and correspond to the same pictures. The data shall be the native HEVC/H.5 stream and shall not be comprised into a container format. Note: This means that no audio data can be added into the stream.
