Visual, non-text equivalents may include, for example images, animations, or videos. These are especially helpful for non-readers who can perceive visual presentations. For example, sighted deaf non-readers may benefit from video equivalents in manual communication (sign language). Non-readers, whether they have disability or not, may also benefit from highly graphical equivalents.

Non-visual, non-text equivalents are very diverse. Among the most common are pre-recorded audio of music, spoken language, or sound effects. Such equivalents would be especially important for non-readers who can perceive audio presentations. Presentations in the audio medium of synthesized speech and the tactile medium of braille are usually derived from text or text equivalents so usually require no additional work from the developer.

By the way, we know we shouldn't use animated images (see checkpoint 7.3) and we know that the bit-mapped text used for the caption should have been created with Cascading Style markup (see checkpoint 3.1). Would you believe "poetic license".
