Abstract
Methods, systems, computer readable media, and apparatuses for providing enhanced content are presented. Data including a first program, a first caption stream associated with the first program, and a second caption stream associated with the first program may be received. The second caption stream may be extracted from the data, and a second program may be encoded with the second caption stream. The first program may be transmitted with the first caption stream including first captions and may include first content configured to be played back at a first speed. In response to receiving an instruction to change play back speed, the second program may be transmitted with the second caption stream. The second program may include the first content configured to be played back at a second speed different from the first speed, and the second caption stream may include second captions different from the first captions.
