That is, the correspondence table first finger decide the program of subscription and video recording information (channel, begin video recording constantly, stop video recording constantly), picture recording schedule information, whether to carry out code conversion (code conversion processings), the timing of code format, image size, bit rate and code conversion after changing.
Fig. 5 represents the state for a plurality of program subscription kinescopes.In the program of channel 1, whether to carry out code conversion and be will, the code format after the conversion is that MPEG4, image size are that HD (High Density), bit rate are after the timing of 10Mbps, code conversion is video recording.In the program of channel 3, whether to carry out code conversion and be will, the code format after the conversion be MPEG4, image size be SD (Standard Density), bit rate be the timing of 2Mbps, code conversion be 2:00 appointment constantly.By rewriting subscription and video recording table T1, can easily change regularly.
Fig. 6 is the ideograph that can expression carry out the example of code conversion table T2.
As shown in the drawing, before can carrying out among the code conversion table T2 corresponding expression conversion code format, conversion post code form, image size, bit rate and can change every, the timing that is used for being undertaken by timing judging part 32 code conversion is judged.Code format before and after the conversion is corresponding with the load that the code conversion processing offers picture recording and reproducing portion 20.Therefore, can carry out code conversion by judging, and can avoid picture recording and reproducing portion 20 excess loads according to the code form before and after the conversion.
Here, the data format of broadcasting (conversion before code format) is MPEG2, will change the post code form and divide into MPEG4, H.264 two kinds.With the image size discrimination is two kinds of SD, HD.In the image size is under the situation of SD, and bit rate is divided into two kinds of 2Mbps, 6Mbps, is under the situation of HD in the image size, and bit rate is divided into three kinds of 5Mbps, 10Mbps, 20Mbps.
Its according to the conversion of being broadcasted before code format, conversion post code form, image size and bit rate decision can carry out code conversion.That is, treating capacity that can be required (depending on code format, image size, the bit rate of conversion front and back) according to code, can decision carry out code conversion.
Expression is from the guide picture shown in Figure 4 selected chosen content of operation (process information selections) by operating portion 10 among the processing selecting table T3, is used for the timing judgement of the code conversion undertaken by timing judging part 32.
Reproduce under the preferential situation in the processing selecting information representation, the code conversion of interrupt images data etc., and begin its reproduction.And, after the reproduction, restart the code conversion of view data etc.
And, under the preferential situation of processing selecting information representation code conversion, do not reproduce view data etc., and proceed the code conversion undertaken by lsb decoder 23.
(action of recording apparatus 100)
The action of the recording apparatus 100 of this example then, is described.
Fig. 7 is the flow chart of an example of the sequence of movement of expression recording apparatus 100.
Set video recording switch condition (step S101).
That is, analyze by the subscription and video recording of operating portion 10 inputs and the information of code conversion, and it is recorded as subscription and video recording table T1 by information analysis portion 31.
Concrete, input specify the program of subscription and video recording information (channel, begin video recording constantly, stop video recording constantly), picture subscription and video recording information, whether to carry out code conversion (code conversion processings), the timing of code format, image size, bit rate and code conversion after changing, and be stored as subscription and video recording table T1.
Then, judge whether to begin video recording (step S102).According to " zero hour " that whether reach subscription and video recording table T1 begin video recording constantly, carry out this judgement.
If be judged as under the situation that begins to record a video, judge whether to carry out code conversion (step S103) among the step S102.According to subscription and video recording table T1 " whether will change " with can carry out code conversion table T2 and carry out this judgement.That is, be to want, can carry out code conversion table T2 subscription and video recording table T1 " whether will change " under the situation of " can change ", carry out code conversion, in other cases, do not change.
At this moment, according to can carry out the code format before code conversion table T2, the conversion, can code format, image size, the bit rate after the conversion carry out the judgement that change.In addition, can itself change from the view data imported etc. before the differentiation of code format.
Among the step S103, can not carry out under the situation of code conversion being judged as, by the control of step S1, only will output to recording portion 24, and the former states of still not changing such as view data record (step S104) in the recording portion 14 from view data of input part 21 etc.Constantly stop this flow process finishing to the record of recording portion 14.
On the other hand, be judged as in step S103 under the situation of carrying out code conversion, can judgement handle code conversion (step S105) in real time.Whether the utilization rate according to CPU carries out this judgement more than or equal to predetermined reference value.
In step S105, be judged as under the situation about can handle in real time, record a video after the code conversion view data etc. (step S106).That is, according to " code format ", " image size ", " bit rate " of subscription and video recording table T1, encoding section 23 is carried out code conversion.
At this moment, by switch S 1, the output of input part 21 only is connected to lsb decoder 22.In addition, by switch S 2, S3, the output of lsb decoder 22 only is connected to encoding section 23.
In case the real-time code conversion of view data etc. and stop to the recording processing of recording portion 24 then stops this flow process.
In step S105, be judged as under the situation of not carrying out real-time code conversion, do not carry out the code conversion of view data etc., and former state record in the recording portion 24.
At this moment, only will be connected to recording portion 24 from the output of input part 21 by switch S 1, encoding section 23 is a non-action status.
Behind the video recording, judge that whether the video recording switch condition set is the conversion (step S108) behind the video recording.At this moment, judge whether it is code conversion behind the video recording according to " conversion timing " item of the subscription and video recording table T1 of video information maintaining part 27.So-called " conversion behind the video recording ", be meant from the video recording moving image less the elapsed time during in, the moving image behind the video recording is carried out code conversion (also comprising the code conversion that video recording carries out after stopping at once).
Be judged as in step S108 is that according to " code format ", " image size ", " bit rate " of subscription and video recording table T1, encoder 23 carries out code conversion under the situation of the code conversion behind the video recording.
At this moment, view data of the non-code conversion of being write down in the recording portion 24 etc. is outputed to lsb decoder 22, will output in the encoding section 23 by lsb decoder 22 decoded view data etc.
If this code conversion and to the end of record once more of recording portion 24 then stops this flow process.
Among the step S108, under the situation of conversion that is judged as after setting is not video recording, judge that whether previous setting is the code conversion (step S110) of recording apparatus 100 when not using.Carry out this judgement according to " conversion timing " in the subscription and video recording table T1 of video information maintaining part 27 item.
In step S110, be judged as under the situation of the code conversion when not using, judge whether CPU usage is lower than predetermined reference value (for example, utilization rate 50%) (step S111).The utilization rate that this judgement continues to repeat to CPU reaches predetermined reference value.
In step S111, be judged as under the situation of CPU usage less than predetermined reference value, carry out among the step S109 code conversion and to the video recording once more of recording portion 24.
In step S110, be judged as under the situation of the code conversion when not being not use, judge whether to arrive setting (step S112) constantly.According to the moment of record in " specifying constantly " item in the subscription and video recording table T1 of video information maintaining part 27, carry out this judgement.Judge repeatedly up to current time and reach setting constantly.
In step S112, be judged as and arrive set under the situation constantly, carry out the code conversion of step S109 and to the video recording once more of recording portion 24.If this code conversion and stop to the video recording once more of recording portion 24, then this flow process stops.
When the utilization rate of CPU surpasses predetermined reference value in the code conversion of step S109, but also interruption code conversion.During smaller or equal to predetermined reference value, can restart code conversion in the utilization rate of CPU.
In addition, in the code conversion of step S106, also can detect, judge whether to continue code conversion from the variation of the bit rate of the view data of input part 21 output etc.In conversion bit rate uprise and the code conversion situation of difficult under, interruption code conversion, with after former states such as view data be recorded in the recording portion 14, carry out code conversion later on.
In addition, in the code conversion of step S109, under the situation of the view data in having specified the reproduction conversion etc., also can when showing reproduction shown in Figure 4, display unit 40 select picture, it is the preceding video recording of reproduction code conversion that prompting is selected, still first completion code conversion.
In this example, can not carry out in real time under the situation of code conversion, stop laggard line code conversion in video recording.Therefore, even the disposal ability of lsb decoder 22 and encoding section 23 is constant big, also can time-consumingly carry out code conversion.In addition, (or input back) judges whether to carry out code conversion during owing to input image data, and carries out the processing corresponding to this judgement, so can effectively utilize the resource of picture recording and reproducing portion 20.
After the video recording beginning, can not carry out under the situation of real-time code conversion, also can record a video, the state of the loss of data of avoiding recording a video etc. by not carrying out code conversion ground in the variation by bit rate etc.
Set the timing of code conversion by the user, can prevent that the user can not carry out the video recording and the reproduction of program in the code conversion.
