This partner site contains the device partners and certification documentation (including requirements) that devices must comply with in order to carry YouTube Applications (defined below) on Living Room Devices (defined below). ## Access To get access to the rest of the partner site and related materials, see [Accessing Living Room Partnership Resources](https://developers.google.com/youtube/devices/living-room/access/accessing-lr-partnership-resources). ## Content You can find device partners and certification content on this partner site. ## Device Partners The device partners content is for YouTube Living Room device partners who are interested in enabling and distributing the YouTube Living Room applications on their devices. It covers major topics that support partners throughout the entire device certification and launch process---from planning, through to implementation, testing, certification, launch and post-launch maintenance. ### YouTube Applications The YouTube Living Room applications are 10-foot user interfaces intended for "lean-back experience" in the YouTube services. They are all HTML5 based, which means if a web application engine is compliant---if it supports all necessary HTML5 functions---the YouTube Living Room applications can run on any device without modification regardless of the device's underlying platform. In addition to the YouTube main application for Living Room devices, YouTube offers YouTube TV, application, which is available at a different URL. More vertical applications might be added in the future. The device certification process and requirements are for verifying if a partner device meets all the functional and performance requirements to run the HTML5 based YouTube Living Room applications without compromising on the user experience. ## Certification The certification content is split up into two sets of information: - **[Software Documentation](https://developers.google.com/youtube/devices/living-room/requirements/2027/software-certification)**: contains the base Software requirements for supporting YouTube applications; this content is finalized and published in early Q3 of Year 0 for devices that ship to consumers in Year 1. - **[Hardware Documentation](https://developers.google.com/youtube/devices/living-room/requirements/2028/hardware-certification)**: contains the base Software requirements for supporting YouTube applications; this content is finalized and published in early Q3 of Year 0 for devices that ship to consumers in Year 2. ### Revision History and Change Report When changes to the requirements are necessary, those changes will be described at a high level in the Revision History ([Software Revision History](https://developers.google.com/youtube/devices/living-room/requirement-updates/revision-history-software), [Hardware Revision History](https://developers.google.com/youtube/devices/living-room/requirement-updates/revision-history-hardware)). Direct notice will also be given when material changes are made to this document, and YouTube will provide the maximum possible notification time when major changes are necessary. When the finalized Certification Documentation is published (in early Q3), a Change Report ([Software](https://developers.google.com/youtube/devices/living-room/requirement-updates/software-requirements-change-reports), [Hardware](https://developers.google.com/youtube/devices/living-room/requirement-updates/hardware-requirements-change-reports)) will also be published to help partner understand the key changes. This Change Report will also be published when the draft Certification Documentation is shared in Q2 for Partner Feedback. ### Partner Feedback Period On an annual basis, YouTube will publish the DRAFT requirements in Q2 to solicit partner feedback before the requirements are FINAL in Q3. During this period, partners are encouraged to review the requirements and the change report provided. ### Changes after FINAL Requirements Once FINAL requirements are published for a given Certification Year, YouTube will not introduce any new "MUST" requirements for that Certification Year, unless there is an extraordinary circumstance related to Regulatory, Security or Privacy policy. ### Changes to Certification Tests YouTube certification tests can change as long as they are covered by existing requirements. ## Definitions **YouTube Applications** The term "YouTube application" references any of the following three HTML5 applications available on Living Room devices: - The [YouTube on TV](https://support.google.com/youtube/answer/3015415) application, referred to as YouTube Main App in this document. - The [YouTube TV on TV](https://support.google.com/youtubetv/answer/7452153) application, referred to as YouTube TV in this document.
