Abstract

A method for carrying out management on storage unit includes carrying out general deletion of specific media selected by user in stored data, confirming whether volume of stored data and generally deleted data is above standard value or not and carrying out permanent deletion of general deleted data according to principle of priority order if it is. The method for managing storage media is also disclosed.

Description

The method that storage device is managed

[technical field]

The present invention is the invention of relevant storage media managing method, that is to say based on personal video recorder digital storage medias such as (hereinafter to be referred as PVR) storage media managing method that finite storage space and video program are effectively managed.

[background technology]

Recently, home network technologies is popularized, and the product of high-tech such as PVR also enters into market.For function more easily is provided to the user, by big capacity such as hard disks, the technology of the more information of storage and management has become core content on medium.

In situation about using that existing VCR equimagnetic band is repeatedly recorded a video, will produce the image quality variation, when the situation that Video Document is preserved for a long time also the image quality variation can take place, just the problem of original picture appears reducing fully therefore.

Because the mode of tape, if the problem of wanting to find the program that needs also will take a long time to find.

Otherwise, under the situation of the recording apparatus PVR that utilizes hard disk, store with digital form, before storage and the storage after image quality just the same, even use the phenomenon that picture quality degradation repeatedly also can not occur, owing to be to store in the mode of CD, therefore, can find the position of wanting arbitrarily in the fastest time, specific energy is very fast mutually that picture is searched for existing VCR.

But, on mediums such as hard disk,, therefore can not store unlimited many data owing to be subjected to the restriction of the memory space identical with other machines.

In adopting the Digital Television of PVR, to compare with the situation of the space size that can not guarantee to record a video, the capacity of video program is big, and the user will delete certain video program has enough spaces to guarantee hard disk.

In this case, will produce the user for preparing the space situation of some necessary programs of deletion in advance.But, wanted the file that undeletes when in the end free space being arranged again.

But, because it is all deleted to have deleted the programme information of program, therefore, even the file that has unnecessary space also can't undelete in the hard disk.

[summary of the invention]

The present invention is for overcoming the above problems, and storage media managing method of the present invention is: the memory space to the medium of the confined space effectively uses, and the effective program of managed storage.

Storage media managing method according to the present invention comprises: the specific medium of in the storage data user being selected is generally deleted step; Confirm the capacity step more than standard value whether of the data of the data of storage and general deletion; Under the situation more than the standard value, the data of general deletion are carried out the step of permanent delet at the capacity of the data of the data of storage and general deletion according to the principle of priority.

In addition, the data of general deletion and the data space of storage are under the situation more than the standard value, and the present invention also comprises the step by the permanent delet of the priority of storage data.

Storage media managing method according to the present invention also comprises: deletion is according to the step of the particular data of user's selection in the data of storage; Data with above deletion there is the step that partly repeats to retrieve; Delete the step of repeating data according to user's selection.

It also comprises the related data of data of retrieval and above deletion, and deletes the step of above related data according to user's selection.

Utilize and retrieval comprises whether data with above deletion repeat or deny that the related delta data such as information of broadcasting is retrieved energy.

The present invention applies in a flexible way to the memory space of the medium of the confined space, and to the storage media managing method effectively managed of program of storage.

The chart that following reference is enclosed is elaborated to storage media managing method of the present invention.

[embodiment]

The present invention is to provide that the user selects the program broadcast of storing in the hard disk or the information of broadcasting is generally deleted or the method for permanent delet.

The general deletion here is meant: be not that the data on the hard disk are carried out actual deletion, but store as deltreeing, if the user selects these data to be stored again a kind of function that just can restore.

Permanent delet is meant that if do not have special installation or technical specialist, more than Shan Chu content is irreclaimable data actual deletion from the hard disk.

Under the situation of general deletion, the space of relevant data comprises the space of storing data, computer free space then during the situation of permanent delet.

The present invention as shown in Figure 1, will take care of the program of general deletion in the database of classification for medium is effectively managed.The data of promptly general deletion are not deletion or move, but the path of relevant data is cut off, and if it is just restored can be stored in it in the program database again.

Promptly delete priority and determine, and determine according to the standard of user's setting according to time, the deletion time of storage, record a video length, memory space, image quality, channel type etc.

But the deletion priority does not reach in the medium record space under the situation of certain standard, will carry out the order of the data of permanent delet.

User for specific data selects general deletion to be exactly: what it fully reacted is the intention that will delete, therefore, under the situation of the insufficient space of judging medium, just is reflected at priority and data are carried out permanent delet.

For example in Fig. 2, but under the situation of the record space less than 10% of medium, according to deletion priority program 1 at first by permanent delet.

Fig. 3 is the chart that by priority the general deleted data of deleting is described according to the present invention.

At first, in the program of storage, partial programme is generally deleted step S100.Therefore more than in fact the program of Shuo Ming general deletion is not to delete from hard disk, in occupation of the space of hard disk, and at any time it is reduced yet.

Be increased to more than certain standard in the data of general deletion and the space of storage data, when the space of the hard disk that can write down does not reach certain standard,, the program of general deletion carried out permanent delet, step S110, step S120 according to the deletion priority.

For example, the space of recordable hard disk will deleting general deletion according to priority when less than 10%.

The data of storage also are applicable to the deletion priority, under the data conditions that not have general deletion, in the data of storing according to priority permanent delet automatically.

The deletion priority here is that user oneself sets.

Below the automatic searching method that deltrees is described.

What is called deltrees automatically retrieval as to the program that repeats, retrieve with related video program with the program that the user selects, and the user can find necessary catalogue of deleting at an easy rate.

Therefore, the program of repetition is meant: under the situation of recording the program of playing once more, an interior part of perhaps broadcasting content of broadcasting is carried out the meaning of twice above video recording.

If the user selects specific program, will utilize channel, time, exercise question etc. to carry out the retrieval of counterweight knot cluster purpose for information about, perhaps utilize the binary system of whole video programs to search for, and the program that repeats is searched for.

About program forms specific program and series exactly, perhaps with the relevant program of specific criteria (same type, same performer etc.).

It just utilizes data such as standard channel, time, catalogue that user selected program is retrieved.

The for example program 2 of Fig. 3, program 5, program 6, they are relevant each other, and if the user as shown in Figure 4, will propose the relevant prompting that will delete program 2 to the user under the situation of deletion program 5, program 6.

Therefore, also can delete the program relevant 2 according to user's selection with it.

Fig. 5 be among the present invention to the key diagram of selecting the related program of deletion program.

Fig. 6 is the key diagram of automatic searching method of deltreeing.At first, just can realize the automatic retrieval that deltrees according to user's setting, in the case, the user select and the situation of deletion particular category under, will retrieve and provide the catalogue that repeats with relevant catalogue, step S200, step S210.

Under the situation of the program that deletion repeats, retrieve once more and catalogue step S220, step S230, the step S240 relevant with deleting program is provided.

Selection according to the user can be deleted step S250, step S260 together to relevant catalogue.
