According to one embodiment, in response to a user pressing an alternative audio button while watching a television broadcast, the user is provided with a list of secondary audio programs (510, e.g., radio programs received via the Internet) to replace the primary audio program (506) associated with the broadcast. After a secondary audio (510) program is selected, a synchronization (512) component determines an relative transmission delay associated with the secondary audio (510) program. A buffering (514) component then buffers the video program for a period of time equal to the relative delay. A mixing (516) component then mixes the synchronized video (504) program with the secondary audio program (510), which are then presented to the user.
