The embodiments of the invention provide a kind of PVR method for recording, the executive agent of this method can be terminal, wherein terminal
Can be that storage device (such as hard disk, disk) can be installed in PVR set top boxes etc., the terminal, can be with outside storage
Equipment (such as USB flash disk, mobile hard disk) is connected, and processor, tuning demodulator, memory etc., processor can be provided with the terminal
It can be used for the events such as processing video playback, PVR functions, the effect of tuning demodulator is the modulated digital signal that will be transmitted
Demodulation is reduced into transport stream, to be stored and/or be played to video, and memory can be used for storing what is needed in processing procedure
Data and the data of generation.
As shown in figure 1, a kind of individual video video recording PVR method for recording may comprise steps of：
Step S110：For recording the target recording task after preset duration, the available recording in currently stored region is calculated
Duration T2, described is the residual capacity in the currently stored region and the ratio of memory rate with duration T2 is recorded, described to deposit
Storage speed is the ratio of memory capacity and the preset duration that the PVR data recorded take；
PVR functions include the mode such as pre-recording and manual start and stop, and manual start and stop refer to user's opened manually or stopped
Only PVR functions；Pre-recording refers to pre-set the start-stop time (can also be according to wanting recorded program in an electronic program guide
Beginning and ending time determine the start-stop time) and program (target recording task) storage location, reach default time started, equipment
PVR functions are automatically turned on by PVR data storages in specified storage location (currently stored region), at the end of arrival is default
Between, stop PVR functions.For example, as shown in Fig. 2 user is when checking TV guide, it is desirable to which CCTV-1 synthesizer channels are played
News hookup is recorded, and is clicked on and is entered pre-recording interface after pre-recording, can check the programme information of pre-recording,
The storage location of display program at storage location 201, user can also change the storage location of program, can be from sda I, sda
IIth, a certain storage region is selected in the storage device such as sdb I, sdb II, sda, sdb represent different storage devices, I, II generation
Different storage region in table storage device, it is of course also possible to have other naming methods, the invention is not limited in this regard；User
When selecting PVR functions to record program, the storage location selected last time using user is typically given tacit consent to, certainly, selected when last time
When storage location is not present, other storage locations are automatically configured, for example, maximum storage region of remaining space etc.；Reach default
Recording time, equipment automatically turn on PVR functions by the currently stored regions of PVR data Cun Chudao.
Bit rate, definition difference due to different video, compression ratio during storage are different, can all cause the storage taken
Capacity is different, is tied so as to can not accurately judge whether the capacity in currently stored region can be supported to record according only to residual capacity
Beam, and the code check of same channel is essentially identical, therefore there is corresponding relation between memory rate, recording duration, capacity.One embodiment
In, described is the residual capacity in the currently stored region and the ratio of memory rate, the storage speed with duration T2 is recorded
Rate is the ratio of memory capacity and the preset duration that the PVR data recorded take.
The memory rate for recording current PVR data can be calculated according to " memory rate=PVR data ÷ records duration ".
In the case where knowing the residual capacity of memory rate and currently stored region, the remaining appearance in currently stored region can be calculated
How long amount (can use recording duration T2) if can also being recorded, i.e., according to " can use and record duration T2=residual capacity ÷ memory rates "
The available recording duration T2 in currently stored region can be calculated, program residue is recorded duration T1 and can obtained in several ways
Take, for example, with total duration-recorded duration, reservation end time-current time etc. recorded.
Step S120：If the available recording duration T2 in currently stored region is less than remaining recording duration T1, deposited currently
Storage area domain continues to record after buffering duration T3, and switching to target available memory area from currently stored region proceeds recording；
Wherein, the buffering duration T3 is not more than available recording duration T2.
Obviously, when available recording duration T2, which is more than program residue, records duration T1, that is, the surplus of currently stored region is represented
Covolume amount supports to performance recording and terminated enough, and the store path of PVR data can not be modified；And when available record
When long T2 is less than remaining recording duration T1, that is, represent that the residual capacity in currently stored region is not enough to support to performance recording knot
Beam continues to store PVR data, it is necessary to be switched to other storage regions, in order to improve the utilization of currently stored region residual capacity
Rate, the present embodiment is switched to other storage regions when being run low using the residual capacity in currently stored region, can be current
The residual capacity of storage region switches when being less than a certain lower limit, or continues in currently stored region after recording buffering duration T3
Switching (buffering duration T3 is not more than available recording duration T2), can also be less than in the available recording duration T2 in currently stored region
Switch during switching threshold (for example, 2 minutes, 30 seconds etc.), switching to target available memory area from currently stored region is recorded
System, and target available memory area can be designated as to currently stored region, the S110 that repeats the above steps, step S120, until program
Recording terminates.
By the above method, automatic change other storage regions can be arrived in the storage region off-capacity that user selects
Continue to store PVR data, the integrality of performance recording is can guarantee that in the case where disk size is enough, the utilization of disk is improved
Rate and use flexibility.
As shown in figure 3, the target available memory area can be determined by following steps：
Step S321：Judge to whether there is other available memory areas in disk residing for currently stored region；
Step S322：If it is, with the maximum available memory area of residual capacity in disk residing for currently stored region
It is used as the target available memory area；
Step S323：If it is not, then being used as the target using the maximum available memory area of residual capacity in other disks
Available memory area.
The storage region of switching can be in same storage device or in different storage device, for ease of
PVR data are read and write, the present embodiment is preferably switched to be in the available memory area in same disk with currently stored region, when
So, it can also set to be switched to and be in currently stored region in same disk and the maximum storage region of residual capacity, to subtract
The number of times switched less, so as to avoid PVR data storages from excessively disperseing；Certainly, if with disk residing for currently stored region not
When there is available memory area, then the storage region storage PVR data in other disks are only switched into, based on same reason
By being preferably switched to the maximum storage region of residual capacity.
Available memory area can be the arbitrarily detectable storage region for having residual capacity, however, because storage is set
The residual capacity of standby each storage region differs, and some residual capacities are more, and some residual capacities are less even without when residue appearance
When measuring less, may do not record how long switch storage region again so that PVR data storages excessively disperse；In addition, difference is deposited
The read or write speed in storage area domain is also possible to difference, is lost there may be in PVR data Cun Chudao writing speeds too low storage region
Bag phenomenon, being read from reading speed too low storage region may interim card when PVR data are played out.Therefore, in order to cut
The storage region changed has preferable recording result, it is necessary to which the situation to other storage regions is detected, including detection is remaining
Capacity and read or write speed.Because detection needs to expend the regular hour, so detection is completed before switching storage region, in order to
Ensure the accuracy of testing result, be defined again by the result more closely detected, alternatively, the available recording in currently stored region
When duration T2 is less than detection threshold value (for example, 10 minutes, 5 minutes etc., detection threshold value should be greater than switching threshold), other storages are detected
The residual capacity and read or write speed in region, are more than pre-determined lower limit capacity (for example, 300MB, 500MB etc.) and read-write by residual capacity
Speed is more than the storage region of pre-determined lower limit speed (for example, 3MB/s, 5MB/s etc.) as available memory area, is needing switching
Storage region is to continue during storage PVR data, and one storage region of selection can as target from the available memory area selected
Use storage region；It is, of course, also possible to available memory area is ranked up by residual capacity and/or read or write speed, prioritizing selection
Residual capacity it is maximum as target available memory area, to reduce the number of times of follow-up switching storage region；It is of course also possible to from
Selection can use recording duration T2 can as target slightly larger than the storage region that program residue records duration T1 in available memory area
Use storage region.By switching to target available memory area determined by the present embodiment, the reliability of switching can be improved, subtracted
Few switching times.
In the embodiment of the present invention, additionally provide and judge that default storage region is before PVR functions recording PVR data are started
No available method, as shown in figure 4, corresponding step can be as follows：
Step S410：Judge whether default storage region meets residual capacity more than pre-determined lower limit capacity and read or write speed
More than pre-determined lower limit speed；
Step S420：If it is, being used as currently stored region using default storage region；
Step S430：If it is not, then so that residual capacity is more than pre-determined lower limit capacity and read or write speed is more than pre-determined lower limit speed
Other storage regions of degree are used as currently stored region.
As shown in Fig. 2 when user selects pre-recording, there is provided the storage location (default storage region) of PVR data, such as
It is preceding described, the read or write speed of storage region can not too low, residual capacity can not very little, in order to avoid in default storage region residual capacity
When exhausting, the detection to the residual capacity and read or write speed of other storage regions is not completed also, causes recording process to occur of short duration
Interrupt.Detection to default storage region can be carried out when user sets pre-recording, can also record beam worker starting
Making the stage (refer to N minutes wake-up devices and modulated channel etc. are prepared for recording before pre-recording when) is carried out, or twice
Detected；Residual capacity in currently stored region is more than or equal under lower limit capacity and read or write speed be more than or equal to
When speed limit is spent, then keep currently stored region constant；Residual capacity in currently stored region is less than lower limit capacity and/or read-write
When speed is less than lower limit speed, the residual capacity and read or write speed of other storage regions are detected；It is more than from residual capacity and sets in advance
Limited capacity amount and read or write speed are more than one subregion of selection in other storage regions of pre-determined lower limit speed and are used as currently stored region.
So as to avoid occurring in recording process short interruption, not record how long the situation of storage region will be switched, recording is improved
Stability.
In the embodiment of the present invention, the method for additionally providing detection storage region read or write speed, corresponding process step can be with
It is as follows：
Writing speed is calculated according to the test file size write to storage region, write time, readout time, speed is read
Degree, the read or write speed of the storage region is used as using the smaller value in storage region writing speed, reading speed.
As it was previously stated, packet loss phenomenon will be there may be in PVR data Cun Chudao writing speeds too low storage region, from reading
Go out in speed too low storage region to read when PVR data are played out may interim card, in order to ensure recording result, it is necessary to obtain
The read or write speed of storage region is taken, can be and more smart in order to obtain according to the interval of the attributes estimation read or write speed of storage device
True read or write speed, the present embodiment writes test file into storage region by the way of directly testing, from storage region
Read test file；Test file is deleted, writing speed is calculated according to test file size, write time, readout time, read
Speed, using the smaller value in writing speed, reading speed as the read or write speed of the storage region, so as to obtain storage region essence
True read or write speed, to judge whether storage region can use offer foundation.
In the embodiment of the present invention, the method handled after switching storage region PVR configuration files is additionally provided, is such as schemed
Shown in 5, corresponding process step can be as follows：
Step S580：Area identity, relative path, the PVR numbers of target available memory area are recorded in configuration file
According to filename, played out with searching the PVR data that are stored in different storage zone according to configuration file.
Each storage region in storage device can be distinguished by area identity, current storage device is by UUID
(Universally Unique Identifier, general unique identifier) distinguishes each storage region as mark.In order to
It is easy to be managed recorded program, program is recorded using PVR functions, not only needs to store PVR data, it is also corresponding to match somebody with somebody
The PVR parameters that are stored with file, configuration file are put, in general, the quantity of configuration file is fixed, is typically stored at
Selection is recorded in that storage region of program, when recording program in default storage region (storage target recording task PVR numbers
According to first storage region) in automatically generate PVR data record in corresponding configuration file, configuration file in this memory block
The relative path and filename stored in domain, as shown in fig. 6, set top box 600 is with including sda I 610, sda II 620, sdb I
630th, the storage device connection of the storage region such as sdb II 640, such as default storage region is sda II 620, then when recording program,
PVR data storages are in program file 622, while generating path and the file that the record program file 622 of configuration file 621 is stored
Name, due to not including area identity in current configuration file 621, so that, when storing and reading PVR data, can only
Carried out in this storage region, it is impossible to across storage region to be operated.As shown in fig. 7, one embodiment of the invention is in configuration file
Area identity (for example, UUID) is added in 721, storage configuration file 721 and section in default storage region sda II 720
Mesh file (PVR data) 722, when to be switched to other storage regions (such as sda I 710) and stored, in configuration file 721
The middle corresponding UUID of addition (sda I), path and filename, such as also need to be switched to sdb I 730, the memory blocks of sdb II 740
When domain stores PVR data, by continuing to increase corresponding UUID, path and filename in configuration file 721；Play section
During mesh, correspondence is read from storage region sda II 720, sda I 710 etc. according to the information recorded in configuration file 721 successively
PVR data to play program.A general program only has a configuration file in default storage region, is deposited for minute book
The relevant information of storage area domain and the program PVR data in other storage regions, when setting pre-recording for the first time, is referred to by user
Determine storage location (default storage region), after user specifies, the storage device UUID that user specifies can be recorded, and the recording is deposited
Storage area domain storage region by default, need not repeat to specify when preengaging again, certainly, if the remaining appearance in the storage region
Amount can point out user to change storage location when not enough；If the PVR data of a program are distributed in multiple storage regions,
The information such as corresponding UUID are stored in the configuration file in the default storage region, it is each to find program by relative path
PVR data storages can find the PVR data in which storage region by filename, when user will play the section of recording
During mesh, the position of PVR data storages is found by configuration file, the PVR data transferred in different storage zone are played successively,
So as to provide complete playback effects.
In order to which the scheme that above-mentioned PVR is recorded is better described, specific explanations will be carried out by an example below.
As shown in figure 8, step S801：PVR functions, including recorded program, storage region are set according to the instruction of user
Deng；
Step S802：Residual capacity and read or write speed to the storage region are detected, to judge the storage region
Whether residual capacity is more than pre-determined lower limit capacity, and whether read or write speed is more than pre-determined lower limit speed；When two conditions are satisfied by, turn
Step S804, otherwise goes to step S803；
Step S803：A residual capacity is selected more than pre-determined lower limit capacity from other storage regions and read or write speed is big
Currently stored region is used as in the storage region of pre-determined lower limit speed；
Step S804：When reaching the time of pre-recording, start PVR functions and program is recorded；
Step S805：Calculate the remaining of program and record the duration T1 and available recording duration T2 in currently stored region, work as T2>
During T1, S806 is gone to step, S807 is otherwise gone to step；
Step S806：Continue to record and terminate until recording；
Step S807：Judge whether T2 is more than 10 minutes, work as T2>At 10 minutes, S808 is gone to step, is otherwise gone to step
S809；
Step S808：Continue to record until T2<10 minutes；
Step S809：The residual capacity and read or write speed of other storage regions are detected, residual capacity is more than pre-determined lower limit
The storage region that capacity and read or write speed are more than pre-determined lower limit speed is used as available memory area；
Step S810：Work as T2<At 2 minutes, if the available memory area not allowed hand over, the storage region is recorded to
Residual capacity terminate when exhausting to record；
Step S811：Work as T2<At 2 minutes, if there is the available memory area allowed hand over, switch storage region, will cut
Storage region after changing goes to step S805 as currently stored region, repeats said process, until section directory is complete, or because not having
There is the storage region of enough residual capacities and stop recording.
