Method to prevent commercial skip on played back media .

This disclosure takes advantage of the broader bandwidth allowed via the digital and HD protocols. Now that broadcasters are required to switch to full digital mode by 2009, they have been slowly converting their transmissions to digital format from analog format. The key here is that the digital format can hold more data, which is what this patent takes advantage of.

This is the typical stream of a show/event and the commercial break:

-----------------------------------xxxxxxxxxxxxxx--------------------------------------
(show) (commercial) (show)

---------------------------------xxxxxxxxxxxxxxxxxxxxxxxxxxx-------------------------------------------
- &&&&&&&&&&&&&&&&&&

* * * * * * * * * * * * * * * * * * * *

# # # # # # # # # # # # # # # #

This is the explanation of the symbols:

xxxxx = commercial recorded at regular (1x) speed.
& & & = commercial recorded at one-half (1/2x) speed
* * * = commercial recorded at one-third (1/3x) speed
# # # = commercial recorded at one-fourth (1/4x) speed
