Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 illustrates a home media service apparatus referred to for describing an extended media parsing apparatus according to an embodiment of the present invention.

The present invention is applied to a ubiquitous home media service apparatus based on a single media multi devices (SMMD), and more particularly, to a parsing apparatus for providing an extended media service.

Here, the expandable media includes neo-data added with additional information such as aroma, smell, touch, temperature / humidity, in addition to audio, video, and text, which are existing media. When playing, it is possible to provide a realistic media service by playing a specific effect according to the taste of the individual and the surrounding device environment.

On the other hand, neo data is media data of a new format, and not only metadata for extended media data but also software for playing neo data and software for device control are stored. In addition, additional data such as object type media, experience media, and realistic media is recorded in the neo data, and the recorded additional information is synchronized with device information to which each media is linked.

In this case, the neo data further includes control information, sync information, and identification information for each device for implementing additional information included in the neo data. Here, time, control, and parameter information are recorded in each device information.

The user interface 10 is a means for supporting a user to interact with the system online. The user interface 10 includes a method for causing an application program or a website to interact with or react to the system. As an example, a web browser may be mentioned.

The communication interface 15 is connected to a server providing external expandable media and is a means for receiving predetermined expandable media provided through the server. The communication interface 15 may be connected to the server through a web browser, which is the user interface 10. At this time, the communication interface 15 receives the extended media packet from the server through a streaming method.

The analyzer 20 converts the extended media packet received through the communication interface 15 into data having a predetermined format, and analyzes the 'media' composed of audio, video, text, and the like. Separate them into 'neo-data' which provide specific effects. At this time, the analyzer 20 analyzes the extended media data for each object to extract information about the media and neo data.

The neo data analyzer 30 analyzes the neo data at the request of the synchronization controller 40. In this case, the neo data analyzer 30 detects device control information, sync information, identification information, and the like from the neo data and provides the same to the synchronization controller 40.

The synchronization controller 40 allows the media controller 50 to apply media, that is, audio, video, and text data, provided through the analyzer 20. In this case, the media controller 50 allows the media applied from the synchronization controller 40 to be played through the media player 60. Here, the media player 60 includes all commonly used media playback devices such as TVs, MP3 players, DVD players, video players, and the like.

In addition, the synchronization controller 40 detects information provided through the analyzer 20 and the neo data analyzer 30, that is, device control information, synchronization information, and identification information, and at least one connected based on the detected information. Control the synchronization of the device 80. At this time, the synchronization controller 40 determines the device 80 for reproducing neo-data, and accordingly issues a synchronization signal to the device controller 70.

The device controller 70 determines the reproduction order of the neo data based on the synchronization signals respectively issued from the synchronization controller 40. In this case, the device controller 70 allows the neo data to be played back through the corresponding device 80 in the determined playback order. That is, the device controller 70 drives the corresponding device among the connected devices 80 according to the synchronization signal issued from the synchronization controller 40 to reproduce the corresponding neo data.

Here, the synchronization signal is issued based on the media playback order and time, and the at least one device 80 causes the neo data to be played back while the media is played through the media player 60.

The device 80 is an output means connected to play additional media such as sensory media, experiential media, and object media in addition to the media player 60, wherein the device 80 is located at the periphery of the extended media playback. It is assumed that the device 80 is applied. Of course, in addition to the media player 60 currently in use can be applied through other media playback devices. As an example, home appliances such as TV, audio, air conditioners, and mobile terminals such as mobile phones, smart phones, PDAs, etc. may be included, but are not limited thereto.

The device profile manager 90 is a means for managing a profile for at least one device 80 connected to the device controller 70, and at least one device connected to the device controller 70 at the request of the synchronization controller 40. Provides a profile for 80.

As shown in FIG. 2, the analyzer 20 according to an embodiment of the present invention includes a receiving module 21, a conversion module 23, and an analysis module 25.

First, the receiving module 21 receives the expanded media received through the communication interface 15. When the expanded media obtained through the reception module 21 is streaming data in the form of packets, the conversion module 23 depacketizes the expanded media packets into data having a predetermined format.

The analysis module 25 analyzes the expanded media data converted by the conversion module 23 and classifies the data by objects, and classifies each object by tracks. Of course, it is also possible to analyze existing scalable media data.

In addition, the analysis module 25 reads the meta data of the extended media data to confirm whether the meta data includes the neo data. At this time, when it is detected that the meta data includes the neo data, the analysis module 25 extracts the neo data from the meta data, stores it in a buffer (not shown), and informs the synchronization control unit 40 of this.

On the other hand, the analysis module 25 checks whether the extended media data classified for each track includes a neo data track. If it is determined to include the neo data track, the analysis module 25 extracts the neo data track from the expandable media. At this time, the analysis module 25 extracts the neo data and its header information included in the extracted neo data track, and transmits it to the synchronization controller 40.

The analysis module 25 constructs a neo data tree based on the extracted neo data header information, and stores the neo data tree in a neo data buffer (not shown). Here, the neo data tree arranges neo data extracted from the expandable media in chronological order.

Therefore, the synchronization controller 40 can easily grasp the synchronization time information of the neo data through the neo data tree.

On the other hand, the analysis module 25 detects a media track among the expandable media data classified for each track. At this time, the detected media tracks are read to extract the header information of the media, and the media information is transmitted to the media controller 50 through the synchronization controller 40. At this time, if there is a media track request from the media controller 50 based on the header information of the media, the analysis module 25 detects the requested media track and applies it to the media controller 50 through the synchronization controller 40. do.

In addition, if all the media tracks have been delivered, the analysis module 25 may deliver samples for each media track.

Looking at the operation of the present invention configured as described above are as follows.

3 and 4 illustrate an operation flow for an expandable media parsing apparatus according to an embodiment of the present invention, and FIG. 3 shows an operation flow for extracting neo data from the extended media data, and FIG. 4 shows neo data and It shows the flow of motion to deliver media tracks.

First, referring to FIG. 3, when there is a parsing request for extended media data from the synchronization controller 40 (S100), the analyzer 20 obtains and parses extended media data that has been parsed (S110 and S120). Here, a detailed process of acquiring the extended media data will be described with reference to FIG. 5. The analyzer 20 parses the extended media data for each object (S120) and classifies the tracks for each track (S130). At this time, media tracks and the like are classified from the extended media data and stored in a buffer (not shown).

In addition, the analyzer 20 extracts meta data from the expanded media data and reads it (S140). If it is determined that neo data exists in the metadata, and it is determined that neo data exists in the metadata (S150), the neo data is extracted from the metadata and stored in a buffer (not shown), and the synchronization controller 40 Inform them. At this time, the neo data analyzer 30 extracts and analyzes the neo data stored in the buffer according to the control command of the synchronization controller 40 (S160). Therefore, control information on at least one device for implementing neo data is obtained.

If the neo data does not exist in the meta data (S150), the analyzer 20 immediately performs the 'S170' process.

On the other hand, the analyzer 20 checks whether the extended media data classified for each track includes a neo data track (S170). If the extended media data classified by tracks do not include the neo data tracks, the process proceeds to FIG. 4B to perform the following process. On the other hand, when the neo data track is included (S170), the analyzer 20 analyzes the neo data track to extract the neo data (S180), and proceeds to (A) of FIG. 4 to perform a subsequent process.

Thereafter, as shown in FIG. 4, the analyzer 20 extracts header information of neo data from the corresponding neo data track (S200) and applies it to the synchronization controller 40. Meanwhile, the analyzer 20 constructs a neo data tree based on header information and neo data tracks of neo data extracted in the '200' process (S210), and stores them in a buffer. Here, the neo data tree is an array of neo data stored in a buffer in order of time information.

In addition, the neo data analyzer 30 analyzes the neo data based on the neo data tree stored in the buffer (S220), so as to obtain at least one device control information on the neo data reproduced in association with the media. In this case, the device control information obtained from the neo data analyzer 30 is applied to the synchronization controller 40.

The synchronization controller 40 transmits the neo data stored in the buffer to the device controller 70 based on the device control information applied from the neo data analyzer 30 (S230). At this time, the synchronization controller 40 determines the device 80 to play neo data from the device control information applied from the neo data analyzer 30, and transmits the corresponding device information and the synchronization signal to the device controller 70 together. do.

Accordingly, neo data is reproduced through at least one device 80 connected to the device controller 70.

Meanwhile, after (B) of FIG. 4, the analyzer 20 detects a media track from the extended media data classified for each track (S240), and extracts header information of the media from the detected media tracks (S250). In this case, the extracted header information is transferred to the media controller 50 through the synchronization controller 40 (S260).

If there is a request for a media track from the media controller 50 based on the header information of the media, the media controller 50 detects and applies the media track to the synchronization controller 40, and the synchronization controller 40 respectively applies the media track 50. To be delivered (S270). Here, the process of 'S270' is assumed to be performed until delivery of all detected media tracks is completed (S280).

In addition, if there is a sample request for each media track, the analyzer 20 transmits a sample corresponding to each media track to the media control unit 50 through the synchronization control unit 40 (S290). Here, when the sample delivery for the media track is completed (S300), the parsing operation for the extended media data is terminated.

Meanwhile, FIG. 5 illustrates a process of acquiring expandable media data according to an embodiment of the present invention. In FIG. 3, processes S100 and S110 are shown in detail. Referring to FIG. 5, when a parsing request for extended media is received from the synchronization controller 40 (S100), the analyzer 20 first analyzes the extended media information required for parsing and checks whether the corresponding media is retained data. (S102). If the extended media required to be parsed is retained data, the extended media data to be parsed is detected from the extended media data stored in the buffer (not shown) (S108), thereby obtaining the extended media data (S100).

On the other hand, if the extended media required to be parsed is not the retained data (S102), the server accesses the server and requests the extended media. At this time, when the extended media packet is received from the server (S104), the received extended media packet is stored in a buffer and depacketizing is performed (S106) to obtain the extended media data (S100). ).
