Abstract

According to one embodiment, an image output method comprises causing a second signal processing unit to select a second channel and decode an image signal on the second channel while causing a first signal processing unit to continue outputting a decoded image on a first channel on the basis of an instruction to switch to the decoded image output on the second channel while the first signal processing unit is outputting the decoded image on the first channel, and switching from the decoded image output on the first channel from the first signal processing unit to the decoded image output on the second channel from the second signal processing unit as a result of the completion of the preparation of the decoded image signal output on the second channel by the second signal processing unit.

Dependent claims

An image output apparatus comprising:

a first signal processing unit configured to select a specified channel and decode an image signal on the selected channel;
a second signal processing unit configured to select a specified channel and decode an image signal on the selected channel;
and
an output control unit configured to cause the second signal processing unit to start to select the second channel and decode the image signal on the second channel, while causing the first signal processing unit to continue outputting the decoded image signal on the first channel on the basis of an instruction to switch to the decoded image signal output on the second channel while the first signal processing unit is outputting the decoded image signal on the first channel, and further as a result of the completion of the preparation of the decoded image signal output on the second channel by the second signal processing unit, switch from the decoded image output on the first channel by the first signal processing unit to the decoded image output on the second channel by the second signal processing unit.
