Chris Poole edited this page Oct 16, 2017 · 3 revisions

"Backwards-compatible HDR Video using the HEVC HLG10 Media Profile defined in CMAF supporting resolutions up to UHD (3840x2160). Uses HEVC Main Tier, Main10 profile, 10-bit, up to level 5.1 with BT.2100 HLG transfer characteristics and backwards compatible with BT.2020 colorimetry."

For a Provisional media profile:

Name/company of designated proponent

Chris Poole/BBC

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. Sky Perfect Japan

    2. NHK

    3. TravelXP

      plus many additional trial services including from the BBC and various services using HEVC or HLG but not both, e.g. YouTube.

  2. Digital Media Playback Devices available in the market (at least 5):

    1. LG 2017 televisions

    2. Sony 2016 and 2017 televisions

    3. JVC 2017 4K projectors

    4. Panasonic 2017 televisions

    5. TP Vision (Philips) 2017 televisions

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): NAMES

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: ISO/IEC 23000-19 Common Media Application Format

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

ITU-R BT.2100: Image parameter values for high dynamic range television for use in production and international programme exchange

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:

Test content could be provided quickly if WAVE required licence conditions permit existing test content to be re-used. If not, additional time may be needed in order to create new test content.

Conformance Tools

Timeline:

If MPEG CMAF conformance software is suitable, then the timeline will follow the MPEG timeline for such conformance software.

If WAVE includes any other CMAF HEVC media profile (e.g. HHD8, HHD10, UHD8, UHD10, HDR10) then modifications to conformance software for any of those media profiles to support the HLG10 profile could likely be produced within 1 month of that other conformance software being made available.

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): Y

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

    1.2. In the case of N, ... N/A

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

  3. Any reported incompatibilities with W3C MSE? (Y/N): N
