responsible entities to reliably provide, receive, and display closed captions of video programming made available via using Internet protocol or any successor protocol. (C) Identification of additional protocols, technical capabilities, and technical procedures beyond those available as of the date of enactment of this Act needed for the provision, receipt, and display of closed captions of video programming made available using Internet protocol or any successor protocol. (D) A recommendation for technical standards to address the protocols, capabilities, and procedures identified under subparagraph (B). (E) A recommendation for any regulations that may be necessary to ensure compatibility between video programming made available using Internet protocol or any successor protocol and apparatuses and navigation devices capable of receiving and displaying such programming in order to facilitate access to closed captions. (F) An identification of attributes of easy-to-use authoring tools that can be used by viewers to add closed captions to video programming made available using Internet protocol or any successor protocol. (G) An identification of the categories of entities involved in the online delivery of video programming, along with a recommendation on how to apportion the responsibilities for the provision, quality, pass-through, and display of closed captions among those entities to ensure full access by viewers. (H) A recommendation for best practices for ensuring that programming that was live programming or near-live programming at the time that it was initially made available to viewers is subsequently made available at the level of quality required for prerecorded programming. (I) A recommendation for defining metrics and thresholds to be used for measuring the accuracy, synchronicity, completeness, and placement of closed captions for live programming as necessary to afford access to video programming that is functionally equivalent to the access provided by the audio track, with minimum thresholds
