Description

Method for relocation of broadcasting data

The present invention relates to a broadcast data relocation method for solving the capacity shortage problem generated when storing broadcast data in a mass storage device.

Personal Video Recorder (PVR), which was recently introduced by Tivo and Replay TV in the United States, uses a hard disk for TVs and STBs, and broadcasts programs simultaneously on other stations for up to 30 hours. To record them.

Accordingly, the viewer can simultaneously watch other programs broadcasted in the same time zone by simultaneously recording other broadcast programs and selecting and watching a program to be viewed using the recorded program.

However, the storage device for recording a program has a capacity limit, and even if the storage technology is developed, the capacity limit cannot be completely overcome.

Therefore, in order to continuously store new broadcast data with a limited storage capacity, it is necessary to continuously secure a storage capacity capable of deleting and storing old or unwanted programs.

Accordingly, the Tivo and Replay TVs use a method of specifying a user's manual deletion or how many days to keep as a method to solve the problem.

However, the broadcast program deleting method according to the related art described above has the following problems.

First, the manual deletion of the user is cumbersome to delete continuously if the capacity of the storage device is as small as now (30 hours program recording limit), and also when recording a new program continuously There is a problem of being warned of lack.

Second, the method of designating a deadline to be kept must be set separately for each program, and it is very difficult to set a deadline in a situation in which the program may be viewed at any time.

Therefore, the present invention has been made to solve the above problems, the broadcast data relocation method that can define a variety of options for deleting the program data for effective use of the storage device and can store the desired program for a longer time The purpose is to provide.

1 is a flow chart according to program deletion according to the present invention

A feature of the broadcast data relocation method according to the present invention for achieving the above object is that the first search step for searching whether the storage period elapsed program is set, and if the first search result storage period elapsed program is set; Defining a deletion target list by using the list, a second retrieval step of retrieving whether there is a deletion operation for recording if the first search result storage period has not been set, and the second retrieval step Defining a list of targets to delete all non-preferred programs if there is a delete operation, and deleting the program by manual deletion of a user if there is no deletion, and corresponds to the list of targets defined by the first and second search And selectively deleting the program to be made.

According to another aspect of the present invention, there is a basic period in which a program is stored in a storage device as a storage period elapsed program, a basic period stored in a user definition, a storage period according to a series of broadcasts repeated daily, weekly and monthly, and a user. It includes permanent preservation, which is deleted only by manual deletion, and optional display that the user can check when deleting the program.

Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

The present invention defines various options for program deletion and proposes a method for deleting a program by applying an algorithm using the options.

Options for deleting the program are defined as follows.

First, the default period during which programs are stored in storage

Second, the default period that is saved if you register as a favorite program

Third, how many times to save a series of daily, weekly and monthly broadcasts

Fourth, permanent preservation that can only be erased by manual deletion of a user

Fifth, there are options such as whether or not to receive confirmation from the user when the program is deleted.

The defined options are described in detail as follows.

First, let's look at the default period options in which a program is stored on storage.

The basic period refers to the period in which the program is stored in the storage device, and the storage of all programs is stored based on this value.

The user changes this for each program through the stored program list.

This period can also be specified differently for each program category.

In other words, since the user's preferences are divided into categories, it can be specified differently.

If the user does not specify it, the default value is provided.

Secondly, let's look at the default period that is saved if you register as a favorite program.

In this case, unlike a program that is repeated every time, such as news, the user sets the storage period differently in case of a favorite drama or movie, so that the user can keep it for a longer time.

Third, let's take a look at how many times you want to store a series of daily, weekly and monthly broadcasts.

Unlike a one-time movie or sports program, this can be specified to keep only a few recent times for programs that are repeatedly broadcast every day, every week, and every month.

For example, in case of news or weather program, only one episode is stored, and in case of weekend soap opera, it is generally aired on Saturdays and Sundays.

And whether the series is or not is specified by the user, in this case, by managing the data of the program stored with the same title to find out by comparing with the previous data.

If information about this series is defined in a protocol that contains program information, such as the Electronic Program Guide (EPG) or the Program and System Information Protocol (PSIP), use it.

Fifth, let's look at the permanent retention option, which can only be erased by user's manual deletion.

Viewers may have a desire to continue watching their favorite movie program.

In this case, in addition to the general options mentioned above, it is an option to permanently store in the storage device unless the user directly deletes them.

Fifth, let's look at the option to ask for confirmation when deleting a program.

You can set the program to delete from the system according to the four options described above.

If the storage device runs out of capacity, the program will be deleted automatically or the user will be deleted. Are you sure you want to delete?' Option to receive confirmation of user through message.

Such deletion of a program is performed only when the capacity of the storage device is insufficient, but selection of a program to be deleted is performed periodically.

Therefore, even if the capacity is not insufficient, the user can preview the list of programs to be deleted in the future, and also secure the capacity of the future storage device before the recording time or the recording reservation time.

And the deletion of the currently stored program occurs for the following two cases.

The first method is to delete the remaining capacity in the current storage device than the storage capacity required for storing the program during manual recording or scheduled recording through the EPG (Electronic Program Guide).

Secondly, the user can see the list of stored programs and delete them through the direct delete command.

In this case, the second method is the same as the file deletion method used in a personal computer (PC).

The first method calculates the required storage space using information such as the quality and airing time of the program, and deletes it when there is a shortage of storage capacity.

At this time, the program list to be deleted is deleted as many programs as necessary capacity, not all the programs of the list to be deleted.

Before performing the actual delete operation, it is determined whether or not to be confirmed by the user according to the setting of the fifth option described above.

The process of deleting a program performed using such an option will be described with reference to the drawings.

1 is a flowchart illustrating a program deletion according to the present invention.

1, first, it is searched whether the storage period elapsed program is set (S1).

At this time, the storage period elapsed program is a program for executing the five options described above.

If the storage result elapsed program is set as a result of the search, the programs whose storage basic period has passed (set in options 1 and 2) and the programs whose storage intervals have passed (set in option 3) are classified into a program deletion target list (S2). ).

If the storage period has not elapsed, a program is searched for a deletion operation for recording (S7). If there is a deletion operation for the search result, all non-preferred programs are designated as deletion target lists (S8).

At this time, if there is an unexplored program of storage period is repeated (S3).

Subsequently, the search result (S7) indicates that there is no deletion target (S9), and if the user deletes the selected program manually (S10) and deletes the selected list (S11).

When the deleteable programs are transferred to the deletion target list, the program list is displayed on the screen at the time when the program deletion is requested or when the user requests the deletion target program list (S4).

When the program deletion is requested, the program is deleted by the required storage capacity (S6).

At this time, the user deletes the program sequentially according to the deletion order of each program predefined by the user.

That is, first delete the series, then delete a program not registered as a favorite program, and then delete a program registered as a favorite program (assuming that it is defined in the order listed above).

In this way, by deleting the programs one by one, it is searched whether the required storage capacity is satisfied (S6).

When the storage result is satisfied, the storage capacity is displayed (S12) and the deletion is stopped.

If a deletion operation is made at the time of recording / recording reservation, the remaining process (eg, recording start) is continued using the available capacity generated by the deletion.

As described above, program deletion is performed when a new broadcast program is recorded or when a recording capacity is insufficient when a recording is scheduled, or when a user directly requests program deletion.

Therefore, in the case of recording, the program to be erased is selected to prepare the capacity of the storage device necessary for recording the designated program.

In addition, even if the program is not actually deleted, the list of programs to be erased can be shown on request by the user, and if the user wants to extend the storage period on his own, it can be extended by the default period to be stored or a user-specified period. Do.

As described above, the broadcast data relocation method according to the present invention defines various options for deleting a program stored in a storage device, and accordingly deletes the program, thereby effectively using the limited capacity of the storage device. It can increase.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
