For a Provisional media profile:

Overview of the Media Profile

The media profile includes the following features:

  • HEVC codec with profile Main10, Main Tier and level to 5.1
  • Permits up to 4K video frames (3840 x 2160) and a frame rate up to 60fps
  • Two options exists
    • the "709" option
      • colour_primaries set to 1 (This value is equivalent to the definitions in ITU-R BT.709. For details refer to ISO/IEC 23008-2.)
      • transfer_characteristics set to 1 (This value is equivalent to the definitions in ITU-R BT.709. For details refer to ISO/IEC 23008-2.)
      • matrix_coefficients set to 1 (This value is equivalent to the definitions in ITU-R BT.709. For details refer to ISO/IEC 23008-2.)
    • the "2020" option
      • colour_primaries set to 9 (This value is equivalent to the definitions in ITU-R BT.2020 [8]. For details refer to ISO/IEC 23008-2.)
      • transfer_characteristics set to 14 (This value is equivalent to the definitions in ITU-R BT.2020 [8]. For details refer to ISO/IEC 23008-2.)
      • matrix_coefficients set to 9 (This value is commonly also known as ITU-R BT.2020 [8] non-constant luminance. For details refer to ISO/IEC 23008-2.)

Note that this profile is currently undergoing a corrigendum in MPEG. The above reflects the information from the proposed corrigendum.

Also note that the profile is compatible with at least the following definitions:

  • UHD10 in DVB UHD-1 phase 1 as defined in TS 101 154
  • UHD10 in ATSC A/341
  • UHD HEVC in 3GPP TS26.116
  • UHD 4K profile in DASH-IF IOP v4.1

Name/company of designated proponent

Thomas Stockhammer (tsto@qti.qualcomm.com)/Qualcomm

Note: The Designated proponent is responsible for providing all deliverables necessary to meet the WAVE Media Profile requirements.

Market relevance

Meet at least one of the following conditions.

Codec with existing market relevance

  1. Digital Media Service Providers (at least 3):
  1. Digital Media Playback Devices available in the market (at least 5): i. Qualcomm Snapdragon powered devices from LG, Samsung and Sony ii. Sony Playstation iii. Blu-Ray players:

Codec with WAVE membership support

  1. Device manufacturers which are WAVE members (at least 2): NAMES

  2. Content providers which are WAVE members (at least 2):NAMES

  3. Other Wave members (at least total of 6 including the above members): Qualcomm

Note: A WAVE member company self-declares at the time of voting whether they wish to be considered a device manufacturer, a content provider or other.

Open standards

List the standard for the media profile:

  1. ISO/IEC 23000-19 Information technology — Coding of audio-visual objects — Part 19: Common media application format (CMAF) for segmented media
  2. ISO/IEC: “Information technology – High efficiency coding and media delivery in heterogeneous environments – Part 2: High efficiency video coding,” Doc. ISO/IEC 23008 2:20151.

Note: To meet the WAVE Media Profile ‘open standard’ requirement, the media profile in question must have been developed following an open specification process which supports independent implementations, or is in the process of being published under such a process.

Normative references

List the normative reference of the media profile:

  • ISO/IEC 23000-19 Information technology — Coding of audio-visual objects — Part 19: Common media application format (CMAF) for segmented media

Note: To meet the WAVE Media Profile ‘normative referenceable’ requirement, the organization where the media profile has been or will be published must meet the CTA normative reference policy and be at a level of technical maturity where only editorial changes are possible.

Test and conformance tools

Please provide a timeline for test content and conformance tools.

Test Content

Timeline:

  • 09/2017: A complete set of test vectors

Conformance Tools

Timeline:

  • 09/2017: Initial conformance software for checking CMAF file format level requirements
  • 11/2017: Complete conformance software for checking CMAF FF level and HEVC level requirements

Note 1: To become an approved WAVE Media Profile the test and conformance tools for content verification as well as test vectors for device verification must be available to WAVE.

Note 2: Media Profiles included in this specification for which no test and conformance material is provided are only published as Provisional WAVE Media Profiles and may be removed if no test and conformance material is provided before releasing a new version of this specification.

For an Approved media profile:

WAVE compatibility

  1. Does the media profile specification include its ISOBMFF encapsulation? (Y/N):

    1.1. If the case of Y, which organization/spec? ISO/IEC 23000-19

    1.2. In the case of N,

    Do you have a preliminary draft to be included in a WAVE spec? (Y/N):

When will the complete media profile specification be published by external org? DATE

  2. Have you tested the media profiles with W3C MSE? (Y/N): Y

  3. Any reported incompatibilities with W3C MSE? (Y/N): Y (not available on Chrome despite device support)
