ISSUE - 4: One of the commenters felt that many of the messages in the public archive address important issues (in particular, Eric Hanson's revision to checkpoint 1.3) They also felt that animation should be included in many places in the document to accompany "movie" e.g. in Guideline 1, checkpoint 1.3. They thought perhaps, "video and animation" would be better terms. Reason for the suggestion, is that they are referred to as video and animation in multimedia literature. PROPOSED RESOLUTION: Checkpoint 1.3 has been revised to address the issues raised. Also some other changes have been made to reflect other comments on the list (see change log for details). Note that there are limits to what we can do to change the guidelines however, once they have gone to proposed recommendation. SPECIFIC WORDING: RE Checkpoint 1.3 For your analysis, three versions of the checkpoint are shown here. First, the checkpoint as it was in the proposed recommendation. Second the checkpoint after the last teleconference call. Third, a new version to incorporate the "animation" issue. ORIGINAL CHECKPOINT 1.3 1.3 For each movie, provide an auditory description of the video track and synchronize it with the audio track. [Priority 1] REVISED CHECKPOINT 1.3 1.3 Until most video player technologies can generate an audio description of the video track from a text equivalent (see checkpoint 1.1), provide an auditory description of the video track (synchronized with the audio track per Checkpoint 1.4) LATEST SUGGESTED CHECKPOINT 1.3 1.3 Until most audio-visual player technologies can use speech synthesis to generate an auditory description of the video track from a text equivalent (see checkpoint 1.1), provide an auditory description of the video track (synchronized with the audio track). This also applies to animations that are accompanied by sound or time based user interaction. [Priority 1] [Rationale: there is no need for an audio description of a silent animation unless it is tied to time based interaction with the page (e.g. they need to do something when a particular visual event occurs) in which case it is important to know when something is happening visually. ]
