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, performed by a Set Top Box (STB) comprising processors which control the STB by using a framework, the method comprising:

releasing, by the framework, a full wake lock for the STB, the full wake lock is for sustaining a power state in which both main functions and background functions of the STB are able to be performed;

acquiring, by the framework, a partial wake lock for the STB and entering a first standby state, wherein the partial wake lock is for sustaining a power state in which only background functions of the STB are able to be performed;

shutting down a main processor of the STB;

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

waking up the main processor of the STB; and

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

2. The method of claim 1, wherein the waking up is performed by an auxiliary processor which is communicably connected with the main processor.

3. The method of claim 1, further comprising acquiring, by the framework, the full wake lock for the STB and returning to an active state.

4. The method of claim 1, wherein the main functions comprises one or more of broadcasting, Video On Demand (VOD) service, and recording, and wherein the background functions comprises one or more of STB software update and Event Information Table (EIT) update.
