Abstract

PURPOSE: A multimedia content service support system using a synchronization technique is provided to be used in receiving and using a multimedia file. CONSTITUTION: Server side metadata is received. Local metadata is searched. It is checked that the same file exists in the local metadata by comparing the server side metadata with the local metadata. If the same file does not exist in the local metadata, a virtual file is generated and synchronization is requested. If all files exist in the local metadata, a file in a synchronization directory is executed. If the file partly exists, synchronization is requested.

Description

Multimedia user support system using synchronization technology {Multimedia Content Service Support System using Sync}

It is an object of the present invention to provide a function useful for a user to download and use high-quality, large-capacity multimedia content on the Internet.

The present invention is a system required for an individual to receive and play back high-quality, large-capacity multimedia content on the Internet.

There are many file transfer programs on the Internet. However, most of them are built around the ability to upload or download files. In the case of multimedia content files, multimedia elements cannot be handled and they are processed as separate programs after transmitting general files.

In the present invention, when a user receives and uses a large-capacity high-definition multimedia file provided by a provider through the Internet, there is a problem that the user cannot use the file until the file download is completed. have. In the case of a provider, if there is a need to restrict the use of the user, a function for limiting the use is necessary.

The present invention provides a function that can be used first with only content metadata when a large amount of content is delivered from a provider to a user, thereby enabling rapid distribution and use. In addition, the use of the content can be controlled even after the content is downloaded according to the rights demand of the provider. In case of untransmitted background transfer file, the file is supported in virtual form so that video or sound can be played while downloading immediately through internal file stream controller. This activity is automatically recorded while providing a function that enables the user to download, use, sort, add file information, or edit content. It also transfers this record and provides a sharing function. Accordingly, the contents of the act that the user enjoys alone are developed to be used together through the production and sharing of additional information.

The present invention is utilized when a user receives and uses a multimedia file through the Internet. It can be used as a large file download program and can be used in combination with a multimedia player.

The present invention system 10 for achieving the above object is stored in the directory 20 for synchronization of the file system in the user's computer operating system, when the user downloads a file from the synchronization server device 30 in the remote location .

The invention system 10 includes a file system controller 110, a file monitoring device 120, a file stream controller 130, a metadata manager 140, a file synchronization device 150, and a file transmitter 160.

The file system controller 110 controls the restriction / permission of file use, deletion, and movement of a file. The file monitoring device 120 detects whether a file is changed and notifies the file system controller when control is required, such as whether or not the change is processed. The file stream controller 130 receives the file transmitter 160 from the synchronization server device 30 through the network and stores the file data temporarily stored in the memory as a file, and the multimedia player plays the media file. In case of incomplete file or download, it provides the function to play the video or sound source. The metadata manager 140 provides a function of notifying the file entrustment processing method based on the data recorded on the file, the file distribution information, and the synchronization information. The file synchronization device 150 is in charge of synchronization processing by exchanging and comparing metadata through communication with a system located at a remote location. The file transmitter 160 provides metadata information at a time not used by the user or at the request of the user. Responsible for receiving files in the background.

When the user selects a content file to be received by the synchronization server device 30, the synchronization server device 30 transmits metadata of the selected content file to the file synchronization device 150. The file synchronization device 150 requests the metadata user 140 to verify the received metadata, and the metadata user 140 generates a generation date and a file path based on the file information metadata among the analyzed metadata. When the check is provided to the file system controller 110, the file system controller 110 checks whether the actual file exists.

If the actual file does not exist, the state of the synchronization metadata is changed among the metadata received from the metadata manager 140. The metadata consists of file information metadata, synchronization information metadata, and usage information metadata. The file whose metadata is changed is registered in the synchronization queue by the file synchronization device 150 and records the synchronization state in the synchronization information metadata. Thereafter, synchronization is sequentially performed at the time when synchronization is possible. Synchronization is performed by a synchronization cycle set by the file system controller 110. Synchronization period is subdivided into synchronization period set in the server, default synchronization period, and synchronization period by file type. Types of synchronization include passive settings, synchronization settings by other systems, content type settings by providers, and preset settings by providers. There are two types of synchronization points: immediate synchronization, synchronization setup time interval type, computer-free operation type, and user manual operation type. The timer in the file transmitter 160 operates by the set synchronization period to receive a file based on the synchronization information in the synchronization queue. Before reception starts, the metadata manager 140 prepares the file information metadata in a ready state, and the file system controller 110 creates a file in the corresponding directory by the metadata and secures an empty space as much as the file size. When the reception starts and proceeds, the metadata manager 140 sets the file information metadata in a progress state, and the file system controller 110 sequentially records the data received from the file transmitter 160 in an empty space of the file. While recording, the file access information of the metadata is changed so that the part where the recording is completed is allowed. When the file reception is completed, the file system controller 110 checks the file and if there is no problem, makes the file information metadata complete and releases the file access information.

If the existing file exists after the existence of the actual file in the file system controller 110, the file system controller 110 inquires the metadata of the existing file and then converts the file information metadata into the file synchronization device 150. The file synchronization device 150 compares the metadata with respect to the file received from the synchronization server device 30 and checks whether the file is synchronized. In order to receive only when the server-side data is the latest of the two, the synchronization status for reception is recorded in the synchronization information metadata. Thereafter, synchronization is sequentially performed at the time when synchronization is possible.

When there is a change to the file in the synchronization server device 30, the file synchronization device 150 periodically requests the file change confirmation request to the synchronization server device (30). The file change confirmation request period is changed by the synchronization server device 30. When the file synchronization device 150 attempts to access the synchronization server device 30, if the connection is successful, the synchronization connection information is transmitted, which includes the synchronization server information and the synchronization period. For the file change confirmation request, the synchronization server device 30 gives a change list when there are changes. Process changes in the changelist sequentially. Changes can be largely added, modified, or deleted. 'Add' is the same as when a file does not exist locally when receiving a file by the user's selection. 'Change' is the same as the processing method when the file exists locally when the file is received by the user's selection presented above. When the file is deleted from the synchronization server device 30, the metadata of the deleted file is transmitted to the file synchronization device 150. When the metadata is the same metadata compared to the metadata stored in the metadata manager 140, the metadata is transmitted to the file system controller 10 to check whether the file exists in the file path and delete the file. If the deletion of the file fails, the failure result is recorded in the synchronization file metadata and registered in the synchronization queue. Thereafter, synchronization is sequentially performed at the time when synchronization is possible. At this time, the failure result is notified to the synchronization server device 30. If the file deletion succeeds, the metadata manager 140 also deletes the metadata stored therein.

The file monitoring device 120 monitors the access state of the file and checks whether there is a deletion right or a change right in the file information metadata of the file when the local file is deleted or changed. If there is permission, the deletion and change are allowed, and if there is no permission, the deletion and change are disabled through the file system controller 110. In addition, if the file is in the state of being downloaded or downloaded, the file information metadata indicates whether the file information can be displayed or not accessible by the file map. do. After that, when accessing by opening the corresponding file in another program, the file system controller 110 may block access by checking the authority for each section. The information that can be displayed on the file map includes file accessibility / non-availability indication and file permission status / nonexistence indication.

The file stream controller 130 has a file providing function for a general multimedia file player capable of playing a video and a sound source. The playback function for the file in progress of file reception is determined by comparing the file playback position with the file configuration map by using the file status information of the file information metadata and the file configuration map in the file monitoring device 120. do. If the content of the file longer than the buffering time specified exists in the playback position on the file configuration map, playback is performed. At this time, if the file download is not in progress and is waiting in the queue, the user can immediately change the setting for downloading so that there is no inconvenience for the user.

When the user downloads the content, the file transmitter 160 generates the download record metadata and transfers the downloaded record metadata to the metadata manager 140 to record the metadata of the corresponding content. When the user uses the content, the file stream controller 130 generates the usage record metadata and transfers it to the metadata manager 140 to record the metadata of the corresponding content. When the user adds or edits file information of the content, the file monitoring device 120 detects a file change event, adds, modifies, and transmits file information metadata to the metadata manager 140 to record the metadata as the corresponding content. . In addition, the file monitoring device 120 provides an additional function (comment, recommendation, etc.) for the corresponding content, generates the corresponding metadata, transfers it to the metadata manager 140, and records the metadata as the corresponding content. The file system controller 110 provides processing functions for classification, filtering, and retrieval of contents, and when the user implements it, generates historical metadata about classification, filtering, and retrieval behavior, and delivers the metadata to the metadata manager 140. To record the content as metadata. In addition, the file system controller 110 monitors the copy of the file existing in the synchronization directory and automatically generates parent-child information metadata about the relationship between the original file and the copy file when the copy is in progress. The data is transmitted to the metadata manager 140 and recorded as relationship metadata of the corresponding content. The ownership information metadata of the copy file does not allow the original owner information to be recorded and modified, and the derivative ownership information metadata for the copy file can be generated to prove partial ownership of the modified part. The relationship information is used for tracking and navigation and as a function for DLM (Digital Light Management). The usage history and information metadata thus generated and collected may be transmitted to the synchronization server device 30 through the file synchronization device 150 and may receive information metadata about the same content of another system to share information. to provide.

The file system controller 110 provides a user interface that can comprehensively express various metadata about content. It provides the contents list providing function, the contents detailed information providing function, the content information (comment, etc.) bulletin board function, and the contents preview function. In addition, it provides a recommendation function and a notification function through file information metadata sharing function, and provides a recommendation content viewing function using file information metadata and a popular content viewing function using usage history metadata.
