摘要:
A method, control logic, and executable instructions stored in memory enable faster switching between mobile television channels displayed on handheld devices. In one example, a tuner is controlled to receive a first wireless digital burst, such as a wireless digital burst of a digital video broadcasting-handheld (“DVB-H”) signal, including first channel information. The first channel information corresponds to a first mobile television channel to be displayed, and video based on the first channel information is provided. If desired, battery power consumption by the handheld device is then reduced by turning off the tuner. The tuner is then turned on to receive a second wireless digital burst including second channel information. The second channel information corresponds to the second mobile television channel to be displayed. The second channel information is buffered in a buffer while the video based on the first channel information is provided. If desired, battery power consumption is then reduced by again turning off the tuner. The tuner is again turned on to receive another burst.
