In order to perform secondary processing of broadcast contents, a broadcasting service provider must perform a multimedia transcoding process even if it is processed by a digital signal in the broadcasting process of producing, editing, transmitting, and receiving.

Multimedia transcoding is a technology for reconstructing and providing a single content as an optimum content so that it can be used in different environments due to many factors such as various networks, different processor performances, various user interfaces and user terminal characteristics. The transcoding of the same type is used when a video stream stored in a server is to be transmitted to a terminal having a low performance by adjusting a bit rate, a screen size, and the like. Is used when a video standard is to be converted to another standard when a video stream is transmitted from a server to a terminal having a different standard. Here, transcoding between different types includes a frequency domain based transcoder method and a serial pixel region based transcoder method.

However, in order to implement such a transcoding scheme, a separate device is required. In addition, a delay occurs in a certain time when transcoding is performed in real time, and there is a limitation that transcoded broadcast contents can not be edited immediately there was.

The use of the term "comprising " in this specification is intended to mean that there is a corresponding feature, element and / or component, but not merely that the feature, component, It is to be understood that the present invention does not exclude the presence or addition of a combination of the foregoing. In addition, unless the context clearly dictates otherwise or singular, the singular presentation of the specification and claims should be construed to generally mean "one or more. &Quot;

FIG. 1 is a block diagram of a system including a system for editing broadcast contents according to the present invention through a communication network in real time. System 20 receives broadcast content from a broadcast service provider 10 over a communication network and transmits broadcast content for real-time editing to one or more authenticated user terminals 30, And transmits broadcast contents. Here, the broadcast service provider 10 refers to a main body that transmits a broadcast program (television broadcast, mobile multimedia broadcast, etc.) produced by the telecommunication equipment to the public. For example, the broadcast service provider 10 includes a terrestrial broadcaster, And so on. The external content provider 40 refers to a main body that provides multimedia data that utilizes, processes, and edits the original broadcast content provided by the broadcast service provider 10.

Meanwhile, the communication network between the broadcasting service provider 10 and the system 20 may be a broadcasting communication network such as a terrestrial television broadcasting communication network, a satellite broadcasting communication network, a cable television broadcasting communication network, and the like. (Internet) network, an intranet network, a mobile communication network, and the like. Therefore, not only the 'communication network' shown in FIG. 1 but also the 'communication network' in the present specification is not limited to a specific type of wire / wireless, but may be a terminal device, a transmitting / receiving node, an access point, An antenna and / or a server, a communication satellite, and the like, which can be connected to transmit and receive data between various communicable media or devices.

The user terminal 30 may be a PC (personal computer), a notebook computer, a netbook, a notebook computer, or the like, as long as the user terminal 30 has access to a system that enables real-time editing of broadcast content by an account assigned to access the system 20, The user terminal 30 may be a tablet PC, a subscriber station, a mobile station, a terminal, a remote station, an access terminal, a user equipment (UE), and the like.

According to the system 20 of the present invention, broadcast content that is transcoded in real time in various formats can be easily and easily edited and processed in various ways in an authenticated user terminal 30 (e.g., a PC of an operator who edits broadcast contents) can do. An operator who edits broadcast content by the authenticated user terminal 30 can download the broadcast content from the system 20 via the communication network and upload the edited broadcast content back to the system 20 or convert the edited broadcast content into local data Furthermore, it is needless to say that it is possible to re-edit the uploaded broadcast content to download again.

Now, referring to FIG. 2, a description will now be made of components constituting a system for enabling broadcast contents according to the present invention to be edited in real time via a communication network. The system 20 includes a communication module 21, a broadcast recording module 22, a transcoding module 23, and a management module 24. Each module comprising the system 20 may be implemented by one or more control circuits, a server, and an application program interface (API).

First, the communication module 21 receives broadcast content from one or more broadcast service providers and provides the received broadcast content to the broadcast recording module 22. When there is a request for broadcast content from the authenticated terminal, the communication module 21 transmits the archived broadcast content to the management module 24 and / or uploads the edited content to the authenticated terminal and uploads the broadcast content to the management module 24 And to transmit the stored contents to the external contents provider when there is a request from the external contents provider. 1, the communication module 21 is not limited to a coverage (for example, a near-field or a long-distance communication method) as long as it is capable of transmitting / receiving broadcast contents by a communication network, And can be implemented by any communication method. In other words, the communication module 21 can receive broadcasting contents through a broadcasting communication network such as i) a terrestrial television broadcasting network, a satellite broadcasting communication network, a cable television broadcasting communication network, and the like, ii) an authenticated terminal and archived broadcasting contents and / If the edited broadcast content can be transmitted and received, it means that it is not bound to the communication method or standard.

The broadcast recording module 22 is configured to record raw broadcast contents received from a broadcast service provider in real time. This is a preliminary process for transcoding. Since it is possible to process different resolutions or codecs for different broadcast service providers, the original broadcast content received from the broadcast service provider is recorded before transcoding, 23).

The transcoding module 23 may be configured to transcode the recorded broadcast content to various resolutions and codecs, that is, if the recorded broadcast content is in the first format, . Further, the transcoding module 23 may expand the broadcast content recorded in one format into a plurality of (N) formats and transcoding. Will be described again after describing the management module 24 with respect to the format to be archived to the management module 24 by the transcoding module 23.

Next, the management module 24 archives the transcoded broadcast contents for a predetermined period in a system that allows the broadcast contents to be edited through a communication network in real time without using the separate storage module as the transcoded broadcast contents And transmits it to the communication module 21. Through the management module 24, one or more authenticated terminals can be managed and / or edited on a web basis.

2, the broadcast recording module 22 extracts the caption data from the original broadcast content received from the broadcast service provider in real time, and extracts the extracted caption data in length (e.g., caption data (For example, the number of syllables for the converted value of the subtitle data, etc.) or the subtitle data extracted based on at least one of the time (e.g., the time of the synchronization with the original broadcast content or the time of the specific subtitle data extracted from the original broadcast content) Module. ≪ / RTI > Since the caption data thus adjusted is stored in the management module 24 or a storage module to be described later, the user terminal of the operator can access and edit the data.

2, a system for editing broadcast contents according to the present invention through a communication network in real time may include a separate storage module in addition to the management module 24, The completed broadcast content can be stored for a longer period of time than the management module 24. For example, if the management module 24 is able to store transcoded broadcast content for a week period, the storage module is configured for between one hundred years (gigabytes) and TB (terabytes) per channel, And can store transcoded broadcast content.

Now, with respect to the transcoding module 23, a format that can be supported by a system that enables broadcasting contents according to the present invention to be edited in real time via a communication network will be described. A system for editing broadcasting contents according to the present invention through a communication network in real time can support various resolutions, video codecs, audio codecs, and file formats.

The resolution is a numerical value represented by the number of pixels in the image input / output device. According to the progressive scanning method, the HDTV has a resolution of broadcast contents of 1080p (progressive) at the maximum. The video codec includes Asus, H.261, H.263, H.264, Moving Picture Experts Group-4 (AVC), Advanced Video Coding (MPEG) 4 Part 10, High Efficiency Video Coding (HEVC), MJPEG (Motion JPEG), MPEG-1 Video, MPEG-2 Video, MPEG-4 Part 2, VP8, VP9, QuickTime Animation ADCDM G.726, ADPCM G.722, AMR-NB (Advanced Audio Coding), AC-3 (name for lossy audio compression technology of Dolby Digital) (AMR-Wide band), DCA (DTS Coherent Acoustics), Enhanced AC-3, MP2 (MPEG audio layer 2), MP3 (MPEG audio layer 3) And a variety of PCM methods based on coding and the like. MPEG-4, Ogg, raw AC-3, MPEG-4, MPEG-2, MPEG-4 , SoX native format, WAV, WebM, and WTV (Windows Televison).

By way of example, and not limitation, a system that enables real-time editing of broadcast content in accordance with the present invention over a network can support up to 4k UHD at full resolution and / or can support H.264, AVC, MPEG-4 AVC, Part 10, a video codec such as MPEG-2 video or VP8, an audio codec such as AAC, AC-3, MP2, MP3, and / or a file format such as AVI, Matroska, MPEG-PS, MPEG- .

For example, a system for editing broadcast contents according to the present invention through a communication network in real time includes a first broadcast service provider by 1080p resolution, AVC video codec, AAC audio codec, AVI file format, 720p resolution, MPEG -4 AVC video codec, a second broadcast service provider by MP2 audio codec, a 450p resolution, an MPEG-2 video codec, an MP3 audio codec, and a third broadcast service provider by MPEG-4 file format .

3 is a flowchart illustrating a system for editing broadcasting contents in real time through a communication network in order to edit broadcasting contents in real time. The method shown in FIG. 3 may be performed by each of the modules (communication module, broadcast recording module, transcoding module, and management module) described in FIG. 2 above.

First, broadcast content is received from one or more broadcast service providers by the communication module (step S31). The original broadcast content that can be viewed as input data can be provided by various broadcasting service providers such as a terrestrial broadcaster, a comprehensive channel broadcaster, and a cable broadcaster. Next, the received broadcast content is recorded in real time by the broadcast recording module (step S32). Here, since the broadcast content is recorded in real time, it can be recorded in the format provided by the broadcast service provider.

The broadcast contents recorded in step S33 can be transcoded in real time by the transcoding module. Here, the broadcast contents according to the present invention can be edited through the communication network in real time, In addition to being able to be coded, extended transcoding in a plurality of formats is also possible provided that the preset format permits.

For example, four video codecs (e.g., VC1, VC2, and VC3), four audio codecs (e.g., AC1, AC2, AC3 , And AC4), and five file formats (e.g., F1, F2, F3, F4, and F5) have been preconfigured on a system that allows broadcast content to be edited in real time over a communication network, Codec, and file format (e.g., resolution of R2, video codec of VC1, audio codec of AC4, and file format of F4), and may be transcoded into a preset resolution, video codec, audio Codecs, and file formats, in real-time transcoding in multiple formats (up to 240 formats if the above example).

In step S34, the transcoded broadcast content is archived to the management module. In step S35, the archived broadcast content is transmitted to one or more authenticated terminals or an external content provider server.

FIG. 4 is a flowchart illustrating how a module constituting a system for editing broadcast contents in real time via a communication network according to the present invention provides contents in order to edit broadcast contents in real time. The communication module 21 receives broadcast contents (401), and provides the original broadcast contents to the broadcast recording module (22) (402). The broadcast recording module 22 then records the original broadcast content 403 and provides the recorded broadcast content to the transcoding module 23, which may provide the caption data along with the recorded broadcast content. The transcoding module 23 transcodes the broadcast content provided from the broadcast recording module 22 and transmits the broadcast content to the management module 24 so that the management module 24 archives the transcoded broadcast content (406). The reception, recording, and transcoding of broadcast contents in the series of steps 401 to 406 can be performed in real time, and archiving can also be performed in real time. In other words, although the processes of 401 to 406 in FIG. 4 are described as sequential processes for convenience of explanation, it is noted that this process can be performed in real time.

Next, with respect to the processes from 407 to 410, after the transcoded broadcast contents are archived on a system that enables the broadcast contents to be edited through the communication network in real time, the broadcast contents are provided to the operator who edits the broadcast contents . The communication module 21 verifies whether or not the communication module 21 has been authenticated through the user terminal of the worker and the communication module 21 receives the request for the archived broadcast content from the authentication terminal in step 407, And transmits a request signal for the broadcast contents (408).

The request signal from the authentication terminal includes information on the authentication terminal (for example, a unique identifier of the authentication terminal, an operator's identifier and password information for the authentication terminal, etc.), information specifying the requested content (for example, Format information such as a broadcast content name, a resolution for broadcast content, a video codec, an audio codec, and a file format, date and time information of broadcast content, period information of specific broadcast content, etc.).

The management module 24 having received the request signal provides the broadcast content specified by the request signal to the communication module 21 in operation 409 and the communication module 21 transmits the broadcast content to the authentication terminal 410 ). In the terminal of the operator who is provided with the broadcast contents by the above process, it is possible to edit the broadcast contents in units of seconds or in units of individual image frames of the broadcast contents. These individual embodiment aspects are shown in Figs. 5 to 8 Will be described in detail with reference to FIG. According to the system and the computer readable recording medium of the present invention, it is possible to edit a highlight portion or a fragmentary portion in real time in which real broadcast contents are broadcasted, It is possible to divide broadcast contents for a long time into a short time unit and provide the broadcast contents to a larger number of users.

5 to 8 illustrate exemplary first through fourth exemplary embodiments of editing broadcast content in a user terminal using a system for editing broadcast content in real time via a communication network according to the present invention, Means an individual terminal authenticated with respect to a system capable of editing broadcasting contents in real time via a communication network. Each of the aspects shown in Figures 5 to 8 may also include an output frame that is displayed on a user terminal via a web browser (e.g., Microsoft's Internet Explorer, Mozilla Firefox, Google's Chrome, Apple's Safari, Opera, etc.) .

The first aspect shown in FIG. 5 is an example for explaining how to edit broadcast contents on a user terminal based on broadcast information data provided from a broadcast service provider. When a user selects a specific date and a broadcast service provider (i.e., a broadcaster) by the date selection area 51 and the broadcast service provider selection area 52 in the user terminal, broadcast information data provided by the corresponding broadcast service provider Date schedule table) is displayed in the broadcast information data area 53. [ Such a schedule list can be automatically or manually registered on a system that allows the broadcast contents to be edited in real time via a communication network in cooperation with a broadcast service provider, and it is also possible to modify or delete the schedule list on the output frame of the user terminal.

5, broadcast information data in the case where SBS is selected in the broadcast service provider selection area 52 on March 21, 2014 in the date selection area 51 is output. It can be seen that 'SBS 5 News' is broadcasted from SBS at 5:00 and 'Good Morning 510 - Special Today' is broadcasted at 5:10 from SBS on the corresponding date, and on the right side of the program title, Various information including the playback time can be additionally displayed. Also, broadcast information of the corresponding date can be continuously output after 'Good Morning 510 - Special Today'.

When a specific program is selected from the schedule list of the corresponding broadcast service provider on the specific date provided, the selected broadcast content is requested to a system that enables the broadcast content to be edited in real time via the communication network. Reception of the broadcast content according to the request signal By performing the exemplary method described in FIG. 4, it is possible to edit broadcasting contents at the user terminal. 5, if 'SBS 5 News' is selected in the user terminal (50), the broadcasting contents of the broadcasting program selected from the system for enabling the broadcasting contents to be edited via the communication network in real time are received, You can edit it.

The second aspect shown in FIG. 6 is an example for explaining how broadcast contents provided in real time are edited at a user terminal based on time information. When a user terminal selects a specific resolution and a broadcast service provider (i.e., a broadcaster) by the resolution selection area 61 and the broadcast service provider selection area 62, the broadcast image content provided by the broadcast service provider is displayed as a current image Area 68 and can be confirmed by an operator editing through the user terminal. (For example, units of 1 second, 3 seconds, 5 seconds, etc.) centering on the broadcast image content outputted to the current video display area 68 or in a scene recognition unit identified on the system, The posterior contents of the broadcast image contents can be outputted in the form of frames separated in the continuous image display area 68a.

The second aspect shown in Fig. 6 exemplifies a case where broadcast contents are received from a broadcast service provider in real time, so that the current time is displayed in the time information display area 63, and if necessary, May be selected by the start time designation area 64 and the end time designation area 65. [ With the input keys 64a to 64b and 65a to 65b, it is also possible to move back and forth between the time and the end time based on the input time information.

When the caption view selection unit 67b is designated in the user terminal, the caption information extracted from the broadcast content recorded in the system for enabling the broadcast content to be edited via the communication network in real time may be output to the caption output unit 67c . The subtitle information is synchronized with the broadcast image content outputted in the current video display area 68 and output in synchronization with the broadcast image content.

The broadcasting contents output in this manner can be assigned a first section as a thumbnail by setting a broadcasting section in the user terminal. Here, the first section is a part of broadcasting contents extracted by a predetermined time length it means. Furthermore, the thumbnail designated in the broadcast content is not limited to being limited to only one section, and may be designated as one or more multiple sections (first section, second section, ... nth section). By editing the extracted segment image, the actual broadcast service provider generates clip images and the like for the broadcast program by utilizing the original broadcast contents, and uploads the broadcast contents to a system that enables the broadcast contents to be edited through the communication network in real time, And may be shared with other terminals. Since the clip image generated during the editing process can be checked on the user terminal according to the time length through the edited image confirmation unit 69 and can be re-edited from the stored edited image (if necessary) It is possible to maximize the convenience of editing work.

Next, the third aspect shown in FIG. 7 is an example for explaining how to edit at the user terminal based on the individual image frames included in the broadcast content. When the operator inputs the date and time information to be edited through the user terminal in the time information designating area 71, the video frames of the broadcast content are divided into frames and output on the screen of the user terminal from the video frame of the corresponding time information . In addition, the image frame constituting the broadcast content can be output on the screen of the user terminal for each frame unit recognized as scene change. For example, as shown in the time information designation area 71, when 10:16:00 is selected on April 15, 2014, the video frame at this time is output to the area 75a, and the next frame is sequentially output from the area 75b , The next frame is outputted to the 75c area and can be displayed in the video frame output division areas 75a to 75c, etc., which are divided into the same size in Fig.

On the other hand, when the time information that has been shifted by a predetermined unit period (for example, 5 seconds, 10 seconds, etc.) through the control areas 71a and 71b on the basis of the time inputted in the time information designation area 71, It can also be output from the video frame. The frame selection area 72 can select the number of frames to be downloaded by the operator through the user terminal. As illustrated in FIG. 7, the frame selection area 72 displays '1' in the area 72, The confirmation area 73a may be selected and downloaded. Like the time information designation area, the number of image frames can be adjusted by the area 72a and the area 72b in the user terminal, or directly inputted into the frame selection area 72. [

Further, with respect to an image frame output to all of the image frame output division regions (that is, not limited to 75a to 75c, which means regions divided into the same rectangular size), which is exemplarily shown in Fig. 7, The audio information may appear in the audio information output area 76 in the form of a waveform.

7, the operator can extract the screen shot by designating the image frame unit, and not only the number of frames specified in the frame selection area 72 of the user terminal but also the total confirmation area 73b It is possible to extract a screen shot of the entire image frame, so that editing of the image frame unit as in the third aspect can be usefully utilized.

8 is an example for explaining how the broadcast contents archived or stored in the system for editing the broadcast contents in real time via the communication network is edited in the user terminal based on the time information, Compared with the second aspect, the second aspect is an embodiment for editing broadcast contents provided in real time, and the fourth aspect is an embodiment for editing past broadcast contents archived or stored.

Therefore, the matters described above in connection with the second aspect can be applied to the fourth aspect shown in Fig. 8 in the same way and the like. For example, the user selects a broadcast service provider through the broadcast service provider selection area 82, and the fourth aspect is to edit the broadcast contents in the past, so that the actual broadcast time of the broadcast content to be confirmed by the user terminal is confirmed It is possible to designate through the designation areas 81a and 81b to confirm the image in the form of downloading and streaming. The broadcast image content provided by the corresponding broadcast service provider selected in the user terminal is output to the current image display area 88 and output through the user terminal, and the broadcast image content output to the current image display area 88 is centered (For example, a unit of 1 second, 3 seconds, 5 seconds, or the like) at a predetermined time interval or in a scene recognition unit that is identified on the system, Lt; / RTI > frame.

According to the editing function according to the fourth aspect, the operator can extract and archive the archived broadcast content on a system that enables the broadcast content to be edited through the communication network in real time according to the time specified by the user terminal , And tool tip (tooptip) function.
