ABSTRACT:
Methods, systems, and apparatus, including computer program products, for changing digital broadcast channels. In one implementation, upon receiving a request for switching to a new channel in a digital broadcast receiving device, the device switches from a power saving mode, in which the device processes time-slices only for the currently selected broadcast channel, to a channel changing mode, in which broadcast data is buffered for more than one broadcast channels in anticipation of channel surfing. In another implementation, the user's perception of the channel change delay is mitigated by displaying channel information about the newly selected channel.
