Abstract
Bandwidth optimized channel surfing allow users to experience channel surfing without delay between switching channels when buffering delays are a concern. Audio associated with the surfed channel can be presented to the user in full. Video can be presented at lower frame rates per second than for continuous video. Video sampling or channel surfing mode can mean, for example, that 5 frames per second are displayed to the user. Main video viewing mode can display the full 24 or more frames per second that continuous video is presented at. An interface for channel surfing can determine an automatic switch back to full video. This switch back to full frames per second can occur when a user has hovered over a channel being surfed for a pre-determined amount of time. A user interactive selection of the channel can also result in the switch from channel surfing to main video viewing mode.
