It might be too specific. There's a reason that patents are written in a certain way.
For example, Apple could argue that "the button" on their remote only calls Siri and that that key to feature working is Siri understanding a verbal command "What did he/she/they say" and other such terms.
It could also be argued that "What did he say" (and its variants) and rewinding a video a handful of seconds with the subtitles enabled, could be deemed obvious. I know I certainly had this idea long before Apple implemented it and without having ever seen this patent until today.
Their patent also makes very specific comments about the user getting to set how far the media will jump back, which is not something the Apple TV offers. Again, too specific can hurt you with patents.
The description of certain embodiments (in a patent application) isn't what really matters though. Such descriptions can help to understand, e.g., what the claims describe or why the invention is useful. But it is the claims, and the wording thereof, that really matter. The claims carve out the territory that is legally protected by the patent.
The claims (i.e. the elements of the claims) are worded more generally and are less limiting in terms of what system configurations would be covered by the patent. For instance, the first independent claim doesn't require that a user be able to set how far back the video would jump. It just refers to "a replay position that is responsive a preestablished replay preference." That preestablished replay preference could, in theory, be the amount (of time that a video skips back) that Apple has built into the functionality.

The idea can't be patented. Neither can a feature. If the software code is similar enough that's a different story.
If a system comprises all of the elements referred to in a claim, then it infringes regardless of what the code used to implement those elements looks like - and how similar or dissimilar it is to other code. It is the idea of doing X, Y, and Z (etcetera) in combination that is patented in this case, not the code used to accomplish those things.
