Embodiment
The object of the present invention is achieved like this: a kind of mobile communication terminal that can record and play TV programme is provided, comprise: signal conversion part, analog image and the voice signal exported in the television set are converted to digital signal, MPEG4 encoder, image and voice signal after the conversion are carried out encoding compression; Memory section is preserved image after the compression and voice signal according to different televison program sorting; Control part is saved in memory with image and voice signal after the compression, and the image and the voice signal that are saved in the memory is play output; The MPEG4 decoder is to compressing screen and the loud speaker that back image of preserving and acoustic information are decoded and be sent to mobile communication terminal.
In order to reach the foregoing invention purpose, the present invention also provides a kind of method of using communication terminal to record and play TV programme, comprises: judge television program record state or broadcast state; When judged result is the state of recording TV program, image and the received television program image and the voice signal of conversion input; Image and the voice signal preservation of encoding to input; When judged result is when playing the state of TV programme, need to select the TV programme that has recorded of broadcast; The image of the TV programme selected and voice signal are decoded and outputed to screen and loud speaker.
Below, will describe a kind of communication terminal and using method thereof of recording and playing TV programme of the present invention in detail with embodiment in conjunction with accompanying drawing of the present invention.
Fig. 1 is the annexation schematic diagram between mobile communication terminal and the television set according to the present invention, and mobile communication terminal 20 is docked with simulated television 10 terminals of NTSC mode by adapter.
Fig. 2 is a structure chart of recording and play the communication terminal of TV programme according to of the present invention.
As shown in Figure 2, the mobile communication terminal 20 that can record and play TV programme is made of signal conversion part (below be referred to as ntsc decoder) 21, MPEG4 encoder 22, control part 23, memory section 24, MPEG4 lsb decoder 25, lcd screen 26 and loud speaker 27.
At first, ntsc decoder 21 is converted to digital ITU-R BT.656 or ITU-T BT.601 form with TV programme analog image and the voice signal that television set 10 outputs to mobile communication terminal 20.
MPEG4 encoder 22 can carry out encoding compression by TV programme image and the voice signal that ntsc decoder 21 is converted to digital signal.
Prestore the application program of control mobile communication terminal 20 repertoires in the memory 24, use this application program that the various data of input, output and processing are preserved, and according to different TV programme, to the preservation of classifying of the TV programme image of MPEG4 encoder 22 compression and voice signal.
The repertoire of control part 23 control mobile communication terminals 20 the TV programme image and the voice signal of MPEG4 encoder compresses is saved in memory 24, or TV programme image and the voice signal that is kept in the memory 24 is play in output.
MPEG4 decoder 25 can and be kept at TV programme image in the memory 24 and the acoustic information recovery of decoding with 22 compressions of MPEG4 encoder.
Lcd screen 26 shows the TV programme image that MPEG4 decoder 25 restores, and the TV programme sound that loud speaker 27 output MPEG4 decoders 25 restore.
Fig. 3 is the process flowchart that the method for TV programme was recorded and play to use mobile communication terminal according to the present invention.
As shown in Figure 3, use communication terminal to record and play the method for TV programme, at first, (see step S100) when the user of mobile communication terminal 20 presses television program record or play menu key, judge the state S110 of recording TV program or broadcast TV programme according to the information that is input to control part 23.
When the result who judges is recording TV program for the Menu key of importing, control part 23 can use ntsc decoder 21, in camera, the image that is input to mobile communication terminal 20 is changed (seeing step S120), thus the image of received television program and voice signal.
Pass through the MPEG4 algorithm of MMP (Multi-Media Processor) then, the TV programme image that to export from television set 10 and the data of voice signal are compressed (seeing step S130), and are saved in memory 24 (seeing step S140) by different televison program sortings.
By means of above process, can reduce the data volume that is kept in the memory 24.
On the contrary, when the result of judgement is the broadcast TV programme for the Menu key of importing, control part 23 meetings selected TV program information of search subscriber in memory 24.
Search after the TV programme that the user selects, the image of the TV programme that can select by 25 couples of users of MPEG4 decoder and the voice data S160 that decodes, and output to LCD picture 26 and loud speaker 27, S170.
As mentioned above, use the present invention can realize also in mobile communication terminal, not realizing, the output signal of TV programme is recorded and playing function, make the user not be subjected to the restriction in time and space, TV reception when needed.
In addition, when educational television programmes are recorded and play, can also replace the then educational programs special player.
Though the present invention describes implementation process of the present invention in detail by embodiment and accompanying drawing, the present invention is not limited to above-mentioned example.Under the prerequisite that does not break away from the main idea that requires in the claim, anyone with field ABC under the present invention has the ability to carry out various distortion and implements, and its change will belong in the claim scope of carrying in one's power.
