Time-based media (audio, video and synchronised)
This term is defined by more than one standard, and the wording differs. Each definition below is the one that applies to that standard’s criteria.
Definition in RAWeb 1.1
- Time-based media audio-only: sound content (Wav, Mp3...);
- Time-based media video-only: moving or sequenced images or photos;
- Synchronised time-based media: audio or video streams synchronised with another format to present information and/or including interactive temporal components. Time-based media can be viewed in 2 different ways:
- Downloadable file that can be viewed with software external to the web page;
- Content embedded in the web page which can be consulted within the web page via
- The
<video>element (e.g. a video); - The
<audio>element (e.g. a podcast); - The
<svg>element (for example, a vector cartoon); - The
<canvas>element (for example, a bitmap cartoon); - The
<bgsound>element to broadcast a background sound to the web page.
- The
Time-based media can be broadcast in real time or offered for playback asynchronously (pre-recorded media).
Note 1: animated gifs and image animations created using JavaScript or CSS are not considered to be time-based media.
Criteria in RAWeb 1.1
- 4.1 — Does each pre-recorded time-based media have, if necessary, a transcript or an audio description (excluding special cases)?
- 4.2 — For each pre-recorded time-based media with a synchronised transcript or audio description, are these relevant (excluding special cases)?
- 4.3 — Does each synchronised time-based media have, if necessary, synchronised captions (excluding special cases)?
- 4.4 — For each synchronised time-based media with synchronised captions, are these captions relevant (excluding special cases)?
- 4.5 — Does each pre-recorded time-based media have, if necessary, a synchronised audio description (excluding special cases)?
- 4.6 — For each pre-recorded time-based media with a synchronised audio description, is this audio description relevant?
- 4.7 — Is each time-based media clearly identifiable (excluding special cases)?
- 4.11 — Is the viewing of each time-based media, if required, accessible and operable by keyboard and any pointing device?
- 4.13 — Is each time-based media and non-time-based media compatible with assistive technologies (excluding special cases)?
- 4.14 — For each time-based media that has a synchronised caption or audio description track, are the control features for these alternatives presented at the same level as the main features?
- 4.15 — For each feature that transmits, converts or records pre-recorded synchronised time-based media that has a captions track, are the captions correctly preserved at the end of the process?
- 4.16 — For each feature that transmits, converts or records a pre-recorded time-based media with an audio description, is at the end of the process the audio description correctly preserved?
- 4.17 — For each pre-recorded time-based media, is the presentation of captions controllable by the user (excluding special cases)?
- 4.18 — For each pre-recorded synchronised time-based media that has subtitles, can these be vocalised (excluding special cases)?
Definition in RAAM 1.1
- Time-based media audio-only: sound content (Wav, MP3...).
- Time-based media video-only: moving or sequential images or photos.
- Synchronised time-based media: audio or video streams synchronised with another format to present information and/or including interactive temporal components. Time-based media can be viewed in 2 different ways:
- as a downloadable file that can be viewed with external software;
- content embedded in the software and viewable from the interface.
Time-based media can be broadcast in real time or played back asynchronously (pre-recorded media).
Note 1: animated gifs and images animated by a script in the application are not considered to be temporal media.
Criteria in RAAM 1.1
- 3.1 — Does each pre-recorded audio-only time-based media have, where appropriate, a clearly identifiable adjacent transcript (excluding special cases)?
- 3.2 — For each pre-recorded audio-only time-based media with a transcript, is this transcript relevant (excluding special cases)?
- 3.3 — Does each pre-recorded video-only time-based media have, if necessary, an alternative (excluding special cases)?
- 3.4 — For each pre-recorded video-only time-based media with an alternative, is the alternative relevant (excluding special cases)?
- 3.5 — Does each pre-recorded synchronised time-based media have, if necessary, an alternative (excluding special cases)?
- 3.6 — For each pre-recorded synchronised time-based media with an alternative, is the alternative relevant (excluding special cases)?
- 3.7 — Does each synchronised time-based media have, where appropriate, synchronised captions (excluding special cases)?
- 3.8 — For each synchronised time-based media with synchronised captions, are these relevant (excluding special cases)?
- 3.9 — Does each pre-recorded time-based media (video only or synchronised) have, where appropriate, a synchronised audio description (excluding special cases)?
- 3.10 — For each pre-recorded video-only or synchronised time-based media with a synchronised audio description, is the description relevant?
- 3.11 — For each pre-recorded time-based media, does the adjacent text content clearly identify the time-based media (excluding special cases)?
- 3.13 — Does each time-based media have, where necessary, the viewing control features?
- 3.14 — For each pre-recorded synchronised time-based media, that has synchronised captions or audio description, are the control features for these alternatives presented at the same level as other primary features?
- 3.15 — For each feature that transmits, converts or records pre-recorded synchronised time-based media that has a synchronised captions track, at the end of the process, are the captions correctly preserved?
- 3.16 — For each feature that transmits, converts or records a pre-recorded synchronised time-based media with a synchronised audio description, at the end of the process, is the audio description correctly preserved?
- 3.17 — For each pre-recorded time-based media, is the presentation of captions controllable by the user (excluding special cases)?
- 3.18 — For each pre-recorded synchronised time-based media that has subtitles, can these be, if necessary, vocalised (excluding special cases)?
