In addition, all terms disclosed in this document may be described by the standard document.

1 is a diagram illustrating a system for transmitting and receiving a content guide information according to an embodiment of the present invention.

Referring to FIG. 1, a system for transmitting and receiving content guide information according to the present invention may include a service server 110, a terminal 120, and a network 130. However, the content guide information transmitting and receiving system described below includes at least one of the components shown in FIG. 1, but is not limited thereto.

The service server 110 refers to a server operated by a service provider to provide various services to the user. Here, a service means a structure set of a capability intended to support an application, and includes a real-time TV (Linear TV), an application, a content, a package, and a service collection can do. Real-time TV means a television service in a continuous stream flow from a service provider to a terminal device, and a user can not control the time order in which contents are viewed. An application is a functional implementation realized in software running on one or more interacting hardware. Content refers to material such as video, audio, graphics, etc. used in a service, and may include data and applications. Means a collection of all or a portion of a content element that is intended to provide experience and use together with a package end user.

A service provider is an operator who provides communication services to customers or other users based on tariffs or contracts, and the service provider may or may not operate the network. In addition, the service provider may or may not be a customer of another service provider.

The service server 110 transmits service information provided by the service provider to the terminal 120 in a unicast, multicast or broadcast manner. The service information means information describing in detail a service provided by one service provider, and includes a real-time TV discovery record, a package (service collection) discovery record, a content guide search record a user discovery record, a guide discovery record, a user defined services discovery record, an application discovery record, and a CAS discovery record.

The terminal 120 refers to an end user apparatus that processes and outputs a service provided from the service server 110. [ The terminal described in the present invention may be a personal computer (PC), a notebook, a computer peripheral device, a mobile phone, a smart phone, a tablet PC, a personal digital assistant (PDA), a portable multimedia player (PMP) Mobile devices such as PCS (Personal Communication Service) phone, GSM (Global System for Mobile) phone, WCDMA (Wideband CDMA) phone, MBS (Mobile Broadband System) phone, Internet Protocol Television (IPTV), set- box, an over-the-top (OTT) TV, a TV set such as a smart TV, a monitor, a VoIP terminal or an audio visual media player. Of course, this is merely an example, and it should be construed as a concept including a device that is currently developed, commercialized, or capable of all communication to be developed in the future, in addition to the above-described examples.

The network 130 means a data communication network for data transmission and information exchange between the service server 110 and the terminal 120, and the type thereof is not particularly limited. For example, i-bimnet, which provides high-capacity data transmission and reception services through Internet Protocol (IP), and data service without disconnection, is an i-bimetal architecture that integrates different networks based on IP, It can be network. Also, the network 130 may include a broadcasting communication network, a wired network, a Wibro (Wireless Broadband) network, a Wimax (World Interoperability for Microwave Access) network, a mobile communication network including WCDMA, a High Speed Downlink Packet Access (HSDPA) , A mobile communication network including LTE advanced, a satellite communication network, and a WLAN (Wi-Fi) network.

Hereinafter, a method of transmitting guide information necessary for selecting a content from a terminal will be described in detail.

The content guide information may be provided to the terminal in the form of a content guide discovery record described above, and detailed information (e.g., broadcast channel information or program information) about a program or content provided by each service it means. The content guide information may be referred to as electronic program guide (EPG) information. Each content has an identifier assigned by the provider and may follow the format of a content reference identifier (CRID). The CRID represents a valid value for each content distinction within the service area provided by the provider.

The content guide information may include a guide for specific TV channels and a guide for VOD contents. Video-on-Demand (VOD) is a content-on-demand (CoD) service provided by a user at a request of a user. Means a service that enables users to view content stored on a server. The user can use functions such as stop, play, rewind, fast forward, and time shift.

At present, in TTAK.KO-08.0028, encapsulation and encoding of the Content Guide Fragment conform to the TVA (TV-Anytime) fragment of ETSI TS 102 539, . The content guide may be referred to as a schedule or TVA, but will be collectively referred to as a content guide for the sake of clarity.

2 is a diagram illustrating a process of generating content guide information.

Referring to FIG. 2, the service server 110 generates content guide information as an XML (Extensible Markup Language) file (S201).

Next, the service server 110 divides the content guide information generated as an XML file into fragments (S203). Here, since each fragment has its own independent meaning, it can be transmitted separately.

Next, the service server 110 encodes the segmented fragment into a Gzip file using the Zlip compression algorithm (S205). Here, encoding is used to compress the divided fragments to reduce the size of the content guide, and can be selectively performed.

Next, the service server 110 encapsulates the fragmented fragments into a data container (S207). Here, one data container can be composed of several fragments. The encapsulation structure includes information indicating the data repository, version, and type in which each fragment is stored, and the actual fragment is managed in the data repository in the data container. As described above, the compression process of the fragments can be selectively performed, and thus the fragments can be transmitted in a compressed or uncompressed form in the data container.

The terminal receiving the data container can analyze the constituent elements constituting the container through the container header. The data store that actually stores fragments can be divided into a String Data Repository that stores the string as it is and a Binary Data Repository that stores it in binary form. Whether to use both, Can be determined. When the fragment is stored without compression, it is stored in the string data store in order. When the fragment is compressed and transmitted, it is stored in the binary data area in order.

Next, the service server 110 transmits the data container to the terminal by multicast or unicast (S209).

A method of transmitting content guide information based on a container, a method of transmitting by multicast or a method of transmitting by unicast can be used. DVBSTP (DVB SD & S Transport Protocol) protocol is used to transmit content guide information to a terminal by multicast, and Hypertext Transfer Protocol over HTTP (HTTPS) is used to transmit content guide information to a terminal by unicast. Sockets Layer) protocol may be used. In the case of transmitting to the terminal by unicast, the terminal requests only the necessary content guide to the service server through analysis of the indexing information, and in response, the service server can transmit the content guide information requested by the terminal to the corresponding terminal. Both transmission schemes are compatible with each other and can transmit the same content guide information encoded in the same manner.

3 is another diagram illustrating a process of generating content guide information.

Referring to FIG. 3, the service server 110 inquires about event information (or broadcast program information) in an integrated database (SDT) and generates content guide information as an XML file. In FIG. 3, a case where the payload ID (payload ID) of the content guide information is 0xA3 is exemplified. Here, the payload identifiers are defined from 0xA1 to 0xA5 according to the payload type currently transmitted to the terminal in TTAK.KO-08.0028, and 0xA6 to 0xAF are reserved.

Then, the service server 110 may divide the generated content guide information into fragments, and extract the schedule fragments from the fragmented fragments. The content guide information may include channel information, schedule information, event information, and detailed information. The channel information includes a service information fragment, the schedule information is a schedule fragment, the event information includes a schedule event fragment (Schedule Event Fragment), and detailed information about an event can be generated as a program information fragment. The service server 110 can extract only the schedule fragments from the generated XML file. Here, the event information can be distinguished by the above-mentioned content reference identifier (CRID).

The service information fragment may be generated corresponding to one channel, and the schedule fragment may be configured to be divided into a specific time unit (for example, three hours) per each service information fragment (that is, one channel). For example, assuming that there are 200 channels and the schedule fragment is composed of 3 time units (8 total in a day), a schedule fragment can generate a total of 2000 or more fragments for 2 days.

Then, the service server 110 encodes the extracted schedule fragments using the Zlib compression algorithm to generate a Gzip file. Then, the service server 110 encapsulates the compressed fragments to generate a data container, and stores the generated data container.

The service server 110 may generate an index container using a data container identifier and a fragment key value of the fragment, and store the generated index container. Because of the large amount of fragments, index information can be used to help the terminal find fragments that have the necessary information.

Next, the service server 110 compresses the data container and the index container using the Zlib compression algorithm, and transmits the content guide information to the terminal by multicast using the DVBSTP protocol. The container can be transmitted to the terminal based on UDP (User Datagram Protocol). The terminal first receives and analyzes the index information transmitted from the service server 110, and receives the data container including the necessary fragments.

Meanwhile, the step of generating the Zlib file by compressing the data container and the index container and the step of transmitting by the DVBSTP protocol may be performed in a push server separately configured from the service server 110. In this case, the service server 110 performs the process before the data container or the index container is transmitted to the push server.

As described above, at present, TTAK.KO-08.0028 defines only a method of transmitting all information of the content guide information to the terminal. In this case, even when it is necessary to show the content guide information at the first execution of the terminal, since the terminal must receive and parse the entire information of the content guide information, the terminal needs time to process the content guide information to output the content guide information to the screen So that it is difficult to show the contents guide information of the program currently being broadcasted during the corresponding time.

In order to solve such a problem, only the content guide information for some events (or broadcast program information) related to the current time is provided to the terminal based on the current time by omitting the fragment generation, compression (encoding) According to this situation, a method of selectively receiving content guide information for some events (or broadcast program information) is proposed.

4 is a diagram illustrating a method of generating content guide information including only some events according to an embodiment of the present invention.

Referring to FIG. 4, the service server 110 generates an XML file by extracting only content guide information for some events (or broadcast programs) related to the current time based on the current time (S401).

Next, the service server 110 transmits the generated XML file to the terminal by multicast or unicast, without omitting fragment generation, compression (encoding), and container creation steps (S403).

A method of transmitting the content guide information in a multicast manner and a method of transmitting the content guide information in a unicast manner may be used. The DVBSTP (DVB SD & S Transport Protocol) protocol is used to transmit the content guide information to the terminal by multicast, and the Hypertext Transfer Protocol (HTTP) protocol can be used to transmit the content guide information to the terminal by unicast. Both transmission schemes are compatible with each other and can transmit the same content guide information encoded in the same manner.

5 is another diagram illustrating a method of generating content guide information including only some events according to an embodiment of the present invention.

Referring to FIG. 5, the service server 110 inquires event information (or program information) from an integrated database (SDT) and stores a part of events related to the current time on the basis of the current time And generates an EIT PITF (Event Information present / following table) XML file. Here, the range of some of the events can be variously determined. For example, an event at the current time (i.e., program information currently being broadcasted) may be applicable. In addition, an event of the current time and the next event may correspond to the current event and the next two events. Since the current event and the next event (s) can change in real time according to the current time, the service server 110 inquires the integrated database in real time and can provide the contents guide information to the terminal.

Here, the payload ID (Payload ID) of the content guide information may correspond to 0xEE. It may also have any of 0xA6 to 0xAF reserved in TTAK.KO-08.0028.

The service server 110 may compress the EIT P / F XML file using the Zlib compression algorithm, and then transmit the content guide information to the terminal in a multicast manner using the DVBSTP protocol. Here, the compressed EIT P / F XML file can be transmitted to a terminal based on UDP (User Datagram Protocol). Since the EIT P / F XML file is not divided into fragments but directly transmitted through the DVBSTP section (or encoded using the Zlib compression algorithm and transmitted through the DVBSTP section), the terminal can easily construct XML And the readability and processing speed of the terminal with respect to the content guide information can be accelerated. In addition, since it has only a part (for example, current / next event) for each channel, the capacity is small and can be utilized for a mini EPG (Mini EPG).

6 is a diagram illustrating a method of transmitting a content guide information according to an embodiment of the present invention.

Referring to FIG. 6, the service server 110 generates content guide information including only the current / next event for the entire channel based on the current time, a specific period (for example, one day or two days) (S601). ≪ / RTI > May correspond to a subset of the content guide information including the content guide information including only the current / next event and the entire event for the specific channel for the entire channel. The content guide information may be regenerated (or changed) whenever an event (or a broadcast program) is changed, and may be regenerated (or changed) whenever a current time is changed in a specific time unit ). When the content guide information is regenerated (or changed), the service server 120 provides the regenerated (or changed) content guide information to the terminal 120. Here, the entire channel means all channels that can be served by the service server 110. [ Therefore, even if the content guide information for the corresponding pay channel is transmitted to the terminal 120, the terminal 120 can display the event (or broadcast program) information for the pay channel on the screen It is possible to judge whether or not to output it. FIG. 6 illustrates a case where content guide information including current / next events is generated. However, as described above, the content guide information including some events may include only the current event, (Or more) events.

The service server 110 transmits content guide information including only generated partial events and content guide information including all events to the terminal 120 in a multicast or unicast manner, respectively (S603 and S605). Here, in the case of multicast transmission, each piece of content guide information can be periodically transmitted.

The terminal 120 checks its status and determines whether it is in a state before the content guide information is received for the first time after booting (S607).

In step S607, if the terminal 120 is in a state before the content guide information is received for the first time after booting, the terminal 120 receives the content guide information including only a part of the event, and decodes and parses the content guide information (S609), and outputs the content guide information including only some events to the screen of the terminal 120 (S613). In addition, after receiving the content guide information including only some events and simultaneously receiving the content guide information including only some events in the background, the terminal 120 can receive the content guide information including the entire event.

On the other hand, if the terminal 120 is not in a state before the content guide information is received for the first time after booting in step S607, the terminal 120 receives the content guide information including the entire event, and decodes and parses (S611), and outputs the content guide information including the entire event to the screen of the terminal 120 (S613).

On the other hand, if it is transmitted in unicast, step S607 may be performed first. That is, it is determined whether the terminal 120 is in a state before the content guide information is received for the first time after booting. If the terminal 120 is in a state before the content guide information is received for the first time after booting, The content guide information including only the current / next event for the entire channel can be requested and received. If the terminal 120 is not in the state before the content guide information is received for the first time after booting, the service server 110 ) May request and receive content guide information including the entire event for a specific period (e.g., one day or two days) for the entire channel. At this time, the terminal 120 first requests the contents guide index information to the service server 110, receives the entire index information through the index container from the service server 110, analyzes the index information, The content guide information can be requested by requesting the content guide information by calculating the included data container index and transmitting the index of the calculated data container to the service server 110. [ For example, the terminal 120 may calculate a data container index including content guide information including only some events for all channels based on the current time, or may include content guide information including only some events for some channels The data container index can be calculated. Or a data container index including the content guide information including the entire events for a specific period for the entire channel.

7 is a diagram illustrating a method of transmitting content guide information according to an embodiment of the present invention. In FIG. 7, a process of receiving and outputting the content guide information after booting the terminal 120 is illustrated in the order of time.

Referring to FIG. 7, the service server 110 generates content guide information including only current / next events for all channels based on the current time (S701). May correspond to a subset of the content guide information including the content guide information including only the current / next event and the entire event for the specific channel for the entire channel. As described above, such content guide information can be regenerated (or changed) every time an event (or a broadcast program) is changed. When the current time is changed in a specific time unit (for example, time or minute) (Or changed) every time. When the content guide information is regenerated (or changed), the service server 120 provides the regenerated (or changed) content guide information to the terminal 120. Here, the entire channel means all channels that can be served by the service server 110. [ Here, it is assumed that the content guide information including the current / next event is generated. However, as described above, the content guide information including some events may include only the current event, It may contain two (or more) events.

The service server 110 transmits the content guide information including only the generated event to the terminal 120 in a multicast or unicast manner (S703).

Since the terminal 120 is in a state before the contents guide information is received for the first time after booting, the contents guide information including only a part of the events is received and stored in the interior of the terminal 120 through decoding and parsing (S705) , And outputs the content guide information including only some events to the screen of the terminal 120 (S707).

On the other hand, the service server 110 generates the content guide information including the entire event for a specific period (for example, one day or two days) for the entire channel (S709) The content guide information is transmitted to the terminal 120 in a multicast or unicast manner (S711).

Since the terminal 120 has already received the first content guide information after booting (i.e., the content guide information including only a part of the events), the terminal 120 receives the content guide information including the entire event and decodes and parses the content guide information (S713), and outputs the content guide information including the entire event to the screen of the terminal 120 (S715).

In this way, when the terminal first boots, only the content guide information of the program currently being broadcast on the channel and the content guide information of the immediately following program are received by the terminal and provided to a screen (GUI: Graphic User Interface) And the content guide information for the next channel can be quickly provided to the user. In addition, after receiving the content guide information of the current program / next program, the content guide information of the entire program can be provided to the user by receiving the content guide information of the entire program.

8 is a block diagram of a service server supporting a content guide information transmission / reception system according to an embodiment of the present invention.

8, the service server 110 may include a transmission / reception unit 810, a control unit 820, and a storage unit 830. The components shown in FIG. 8 are not essential, and the service server 110 may be implemented as a server having more or fewer components.

The transceiver unit 810 may include one or more modules that enable wire / wireless communication with the terminal 120. In particular, the transmission / reception unit 810 can transmit the content guide information generated by the control unit 820 to the terminal 120 under the control of the control unit 820. Here, the content guide information may be transmitted in a multicast manner using DVBSTP (DVB SD & S Transport Protocol) protocol.

The storage unit 830 is a means for storing data and programs necessary for the operation of the service server 110 and basically stores an operating program and an application program to be executed by the service server 110.
