As shown in Figure 1, hand-held

100 of the present invention is wherein any products of a PDA(Personal Digital Assistant), a multimedia player (Media Player) and a mobile phone (Mobil Phone), and this hand-held

100 can be used for being electrically connected on the

3 of an outside.

The preferred embodiment of hand-held

100 of the present invention includes a

10, a

11, a

12, a video encoder (Video Encoder) 13, one

14, a

15, a

16 and a

17.

Mandatory declaration be, if the user stores the video data that received in advance in

15, desire when bigger screen is watched, then be that hand-held

100 is connected

3, watch in the

3 of screen area with convenient, and the process of similar this

101 transmission promptly is applicable to notion of the present invention.

In addition, the relevent information that produces in transmission course can be shown at the

17 that hand-held

100 itself has.

In the present embodiment,

16 is used for the electric energy that external power source (figure does not show) is discharged is converted to the required electric energy form of each parts in the hand-held

100.

11 has a

111, an

112 and a

113, wherein,

111 is used for the data processing of keyholed back

10,

12,

112,

113 and

15;

111 controls of

10 controlled

11, by

111 with signal that

10 received allocation process in addition, carry out digitalization operation by 112 pairs of image signals of image process unit and handle, the digitlization signal is encoded to meet the output format of

3 for

13.

13 has electricity-saving function, mainly by 112 controls of the image process unit in the

11 it is switched in one " energy-saving mode " and one " video output mode "; And

14 is electrically connected

13, is to be used for exporting

101 to display

3; And set the mode of " video output mode ", be whether the triggering with

12 determines.

Notion of the present invention is:

11 is in the general operation state, and for example standby or when carrying out other program is to make

13 be " energy-saving mode ", is to make

13 enter dormancy (Sleep) state at this moment; If detect the situation of

13 for " video output mode " of setting arranged, that is the user supresses the

12 that expression need transmit

101, and

11

14 and has connected

3, then

11 just can order

13 to be converted to " video output mode " by " energy-saving mode ", even also

13 enters the normal operation state.

Cooperate shown in Fig. 1,2, the preferred embodiment of hand-held

100 of the present invention for the method for managing power supply of video playback is described, this method comprises following step:

Step 201: during general standby,

11 promptly orders

13 to be " energy-saving mode ";

Step 202: detect whether this

13 of activation is to be set at " video output mode "?

In the present embodiment, be whether to trigger the setting that determines " video output mode ", do not set that then

13 is still and is in " energy-saving mode ", if set, then carry out

203 if having with the

12 that detection hand-held

100 has;

Step 203: show message on

17, the prompting user needs hand-held

100 is connected with

3, and

204;

Step 204: detect

14 and connect

3? if connect, then carry out

205;

Step 205:

11 makes

13 be converted to " video output mode " by " energy-saving mode ", makes it begin to give

3 by

14

101 and is shown; In transmission course, and carry out step 206,207 detection simultaneously.

Step 206: whether the electric weight that the

16 of detecting hand-held

100 is provided low excessively?

In the present embodiment, being used to judge the threshold value that electric weight is whether low excessively, is that the battery of

16 is full of 10% of electric power (Full battery power) amount of power supply, if when the electric weight that records is lower than this threshold value, then execution in

208.

Has step 207: whether the

14 of detecting hand-held

100 removed and being connected of

3? if remove then subsequent steps (A), make video encoder be " energy-saving mode ".

Step 208: on

17, showing warning message, and returning back to

201, making

13 be " energy-saving mode ".

Conclude above-mentioned, because hand-held

100 of the present invention is for the method for managing power supply and the device thereof of video playback, be to make

13 be " energy-saving mode " under the general operation situation, when meeting " video output mode " the situation that detects this

13 for setting, and when

14 has connection to go up

3, then make

13 be converted to " video output mode " by " energy-saving mode ", because promptly avoided unnecessary power consumption at ordinary times, therefore can reach the effect of saving electricity consumption.
