Description

Continuous data recording method in the digit composite video recorder

[technical field]

The invention relates to the invention of the continuous data recording method in the digit composite video recorder, for instance, be exactly in DVD recorder (DVD-Recorder) and DVR incorporate digit composite video recorders such as (HDD-Recorder), can be used for long-time program program etc. to a plurality of CD recording occurring continuouslys.

[background technology]

Fig. 1 is exactly the formation schematic diagram of common digit composite video recorder.For instance, in the digit composite video recorder of DVD recorder and the integrated formation of DVR, its formation mainly comprises as lower device: CD 10, light picker 11, VDR system 12, hard disk 13, HDR system 14, microcomputer 15 and memory 16.

On the other hand, in the superincumbent microcomputer 15, according to user's requirement, the operation of control HDR system 14 can be write down for the similar outside input digit stream of long program program and to be stored in the hard disk 13.

In addition, in described microcomputer 15, according to user's requirement, the operation of control VDR system 12 can be stored in the similar CD 10 of the DVD-RW that carries out re-recordable the similar outer input data stream of long-time program program record.

For example, in the DVD of a re-recordable, in the data flow state that can write down 2 hours programs, write down under the situation of program program of 3 hours length, state documentarily in the process of program program, as after having spent two hours, alternately insert new CD, with one hour program procedure stores of remainder to the CD that replaces.

But,, for alternately inserting new CD, the regular hour, for example to need about time more than 20 seconds, so recorded program program continuously can't be carried out record for the corresponding data flow of important scene with last identical.

In addition, when the long program program of real time programme is recorded in the situation of hard disk, in fact in corresponding machine, regenerate only, so in place arbitrarily, require the user of regeneration by other machine, with the program program that is recorded in hard disk once more duplicated record in the CD identical with recordable DVD.

[summary of the invention]

Thus, the present invention researches and develops for the problem of being deposited above solving, in the incorporate digit composite video recorder such as DVD recorder and DVR, with identical outside input digit flow points such as long program programs is that a plurality of CDs are when writing down, with hard disk as jumbo buffer, pause in the time of can need not a plurality of video disc recording data flow can be carried out record continuously.

For achieving the above object, be divided into following several steps according to its process of continuous data recording method of digit composite video recorder of the present invention: first step: with the traffic logging of input to CD; Second step: when the full situation of video disc recording capacity, the data flow of input is stored to hard disk temporarily; Third step: when new CD replaces, when the data with input continue to be stored to hard disk, temporarily be stored to the data flow on the hard disk before reading; The 4th step: in the CD that replaces, when the digital stream that temporarily is stored to hard disk is all read, will directly be recorded to CD from the data flow of this input in the traffic logging of will read.

Identical with the above, according to the continuous data recording method of digit composite video recorder of the present invention, be in the incorporate digit composite video recorders such as DVD recorder and DVR, in the data flow of video disc recording input; If the video disc recording capacity is full, the data flow of importing is stored to hard disk temporarily; When new CD replaces, when the data with input continue to be stored to hard disk, be stored to the data flow on the hard disk before reading temporarily; In the CD that replaces, when the digital stream that temporarily is stored to hard disk is all read, will directly be recorded to CD in the traffic logging of will read from the data flow of this input.Method of the present invention is in the process of video disc recording data, even replace new CD, and also can be to the new CD continuously record data that replaces.This is very useful for transmitting the identical long-time program of data flow with program to the effective recording occurring continuously of a plurality of CDs.

[embodiment]

Below, implement example according to the ideal of the continuous data recording method in the digit composite video recorder of the present invention, be described in detail with reference to appended drawing.

Fig. 3 is the formation schematic diagram according to the compound video recording grid that continuous data recording method of the present invention was suitable for, for instance, in the digit composite video recorder that DVD recorder and DVR one constitute, its formation comprises as lower device: CD 20, light picker 21, VDR system 22, hard-disk system 23, HDR system 24, microcomputer 25, memory 26 and switch 27 etc.

On the other hand, in described microcomputer, according to user's requirement, the operation of control operation HDR system 24 can be write down for the outer input data stream of long program program and to be stored to hard disk 23.

In addition, in described microcomputer 25, requirement according to the user, control operation VDR system 22, record storage in the similar a plurality of CDs of the DVD-RW of the outer input data stream that re-recordable is identical with long-time program program, at this moment, in the superincumbent microcomputer 25, hard disk 23 as jumbo buffer, even the program program is not interrupted yet for a long time, is carried out continuous recording operation to a plurality of video disc recording the time.

Fig. 4 is the operational flowchart according to the continuous data recording method in the digit composite video recorder of the present invention, for example in described microcomputer 25, and according to user's requirement, setting data recording occurring continuously Mode S 10; The long-time afterwards identical input traffic of program program writes down S11 when requiring strong input to receive in the CD identical with writing down possible DVD again, change over switch 27, and the data flow that the outside is imported inputs to VDR system 22.

On the other hand, in described VDR system 22, to encode and signal processing by the digital stream of switch input for record, beginning is to the operation S12 of CD 10 record data, in the superincumbent microcomputer 25, whether the recording capacity of monitoring compact disc has expired S13.

In addition, the result who monitors, if the recording capacity of CD is full, in the superincumbent microcomputer 25, switch 27 above the conversion, the data flow that the outside is imported inputs to top HDR system 24, simultaneously HDR system 24, after hard disk is set at jumbo buffer, the data flow of input is stored to temporarily the specific region S14 of hard disk.

Simultaneously, monitor whether the user alternately inserts new CD, for example, same as shown in Figure 4, new CD (for example: DISC2) insert in the device, or read the words S15 that finishes, in microcomputer 25, in statu quo keep the transition status of switch 27, the data flow of input is stored to hard disk in real time continuously temporarily, meanwhile, the described VDR of operation control system 22, high power reads out in the data flow that has write down on the hard disk fastly.

On the other hand, with last identical, the traffic logging that the high power fast reading goes out from hard disk in the CD that replaces (for example: S17 in the time of DISC2), monitor the outer input data stream S18 that whether all reads out in interim storage in the hard disk, for example, be recorded in the data recording speed in the CD, and be recorded in data recording speed ratio on the hard disk and be set at and exceed more than two times.

Simultaneously, top supervision result, when the input traffic that is stored to hard disk is all read the words of finishing temporarily, in the superincumbent microcomputer 25, control transformation switch 27, the data flow that the outside is imported inputs to the VDR system, adapts therewith, hard disk no longer is used, and the data flow of input directly is recorded in S19 in the CD that the new friend replaces.

Thus, even when for a long time the outer input data stream of program program is recorded in a plurality of CD, can not interrupt yet, carry out record continuously, so be not only applicable to described digit composite video recorder according to continuous data recording method of the present invention, yet be suitable for other multiple machine.

By above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.
