Abstract

A method for operating multiple standby states and a broadcast receiving apparatus using the same are provided. The method for operating multiple standby states includes releasing, by a framework, a full wake lock for an electronic device, and acquiring, by the framework, a partial wake lock for the electronic device and entering a first standby state. Accordingly, a broadcast receiving apparatus based on an Android framework can operate multiple standby states which are designated by an application.

Claims

1. A method for operating multiple standby states, the method comprising:

releasing, by a framework, a full wake lock for an electronic device; and

acquiring, by the framework, a partial wake lock for the electronic device and entering a first standby state.

2. The method of claim 1, further comprising:

shutting down a main processor; and

releasing, by the framework, the partial wake lock and entering a second standby state.

3. The method of claim 2, further comprising:

waking up the shut-down processor; and

acquiring, by the framework, the partial wake lock and returning to the first standby state.

4. The method of claim 3, wherein the waking up is performed by an auxiliary processor which is communicably connected with a processor.

5. The method of claim 3, further comprising acquiring, by the framework, the full wake lock for the electronic device and returning to an active state.

6. The method of claim 1, wherein the electronic device is an STB, and the framework is an Android framework.
