Hereinafter, a digital broadcasting system for providing a channel switching screen according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

First, a digital broadcasting system for providing a channel switching screen according to an exemplary embodiment of the present invention will be briefly described.

2 is a conceptual diagram for briefly explaining a channel switching screen service according to an exemplary embodiment of the present invention.

As shown, the digital broadcast transmission system 201 (hereinafter referred to as a transmission system) produces a promotional channel switching screen for promoting a broadcast program or delivering announcements and various events and storing the produced channel switching screen. When the satellite 202 transmits the satellite 202 according to the planned schedule, the satellite 202 transmits the transmitted channel switching screen to the terrestrial terminal 203.

The transmission system 201 includes a pilot channel 204, a conditional access system (CAS) channel 205, an electronic program guide (EPG) channel 206, a video channel 207, and audio for providing a broadcast service. A broadcast channel consisting of channel 208 and data channel 209 is used. The pilot channel 204 carries primarily the physical configuration information of the video, audio and data channels 207, 208, and 209, and the CAS channel 205 carries the video, audio and data channels 207, 208, and 209. The access control information of the receiver, and program programming information for the video, audio and data channels 207, 208, and 209 through the EPG channel 206. In addition, broadcast program contents are generally transmitted through video, audio, and data channels 207, 208, and 209. However, the bandwidth of each channel 204 to 209 described above is not fixedly allocated and data can be transmitted through all the channels 204 to 209 described above.

The channel switching screen according to an embodiment of the present invention is transmitted through a channel in which the idle bands of the respective channels 205 to 209 are generated. For example, it is transmitted through an EPG channel 206 that carries program programming information. Since the program schedule information is the schedule information of the broadcast program from 03:00 AM to 03:00 the next day, the amount of broadcast program schedule information at 03 o'clock is the largest and decreases sequentially. As the amount of broadcast program programming information decreases, the idle band of the EPG channel 206 gradually increases to transmit a channel switching screen using the increased idle band. In addition, in the video, audio, and data channels 207, 208, and 209, an idle band may occur as the amount of data transmitted in a standing wave time that a specific channel waves at a specific time may decrease, and channel switching may also occur through the idle band generated. You can send the screen. Therefore, it is economical to provide a channel switching screen service without allocating an additional band.

Next, a digital broadcast transmission system providing a channel switching screen according to an embodiment of the present invention will be described.

3 is a diagram illustrating a digital broadcast transmission system for providing a channel switching screen according to an exemplary embodiment of the present invention.

As shown in the drawing, a digital broadcast transmission system providing a channel switching screen includes a content server 301 that registers and manages a channel switching screen to be transmitted, and a data scheduler that schedules transmission time of the channel switching screen to be transmitted and generates schedule information. 302, the storage unit 303 for storing schedule information of the channel switching screen and the channel switching screen, the channel switching screen and the channel according to the schedule information read and read from the channel switching screen and the schedule information stored in the storage unit 303 A data broadcasting server 304 for outputting channel switching screen file information corresponding to the switching screen, an encoder 305 for receiving the channel switching screen from the data broadcasting server 304 and encoding the received channel switching screen; A PSI / SI server 306 that reads file information of a channel switching screen from 304 and generates a program designation information table and a service information table; A multiplexer 307 that receives the channel switching screen encoded by the encoder 305, the program designation information table generated by the PSI / SI server 306, and the service information table, and converts them into a transport stream (TS); The multiplexer 307 includes a transmitter 308 that receives a transport stream and transmits the channel through an idle band.

The operation of the digital broadcast transmission system providing the channel switching screen having the above configuration will be described in detail below.

A service provider (hereinafter referred to as an operator providing a digital broadcasting service, hereinafter referred to as an operator) refers to a service subscriber (service subscribers are an unspecified majority and all who can use the channel switching screen service according to the present invention). Channel conversion screens such as advertisements and guides for promoting a broadcast program or delivering announcements in various forms and registered in the content server 301, the content server 301 is a registered channel. The switching screen is stored in the storage unit 303. Here, the channel switching screen is composed of one or more channel switching screens of one or more image files (for example, 12 image files).

The worker organizes or changes the schedule and registers schedule information according to the changed or changed schedule to the schedule server 302 so that the channel switching screen can reach the receiver at an appropriate time. The schedule server 302 stores the registered schedule information in the storage unit 303 and simultaneously informs the data broadcast server 304 that the schedule information has been stored.

When the schedule server 302 notifies that the schedule information is stored, the data broadcasting server 304 reads the channel change screen and the schedule information stored in the storage unit 303 and encodes the channel change screen read according to the read schedule information. Passed to section 305. The data broadcasting server 304 transmits the channel switching screen to the encoder unit 305 and also transmits file information of the channel switching screen to the PSI / SI server 306. Here, the file information is information for the PSI / SI server to generate a program designation information table and a service information table of the channel switching screen.

The encoder unit 305 receives the channel switching screen from the data broadcasting server 304 and encodes the received channel switching screen by digital storage media command and control (DSM-CC). Here, the DSM-CC is a protocol for commanding and controlling a digital storage medium (DSM), a device that stores digital information and transmits stored information, and defines functions and interfaces related to bit flow selection and flow control, storage, and management. Doing.

The PSI / SI server 306 stores a program designation information table and a service information table of a multimedia specification for a satellite DMB terminal (hereinafter referred to as a specification) according to file information of a channel switching screen delivered by the data broadcasting server 304. The generated and specified program specified information table and service information table are sectioned and output.

The program designation information table consists of information necessary for demultiplexing the transport stream received by the terminal 203 of the receiver. Accordingly, the terminal 203 decodes the received program designation information table and restores audio, video and data signals according to the information embedded in the decoded program designation information table to provide a service to the receiver through the terminal 203. will be.

The program specific information table is composed of a program association table (PAT), a program map table (PMT), a condition access table (CAT), and a network information table (NIT). The PMT specifies a packet identification (PID) value of a transport stream. . Here, PID is an identifier assigned to packets in a multiplexed transport stream. PID is an identification value that independently compresses and packetizes a channel signal, multiplexes the compressed packets, and transmits them in the form of a transport stream so that packets corresponding to the same channel signal are assigned the same values to distinguish them from packets of other channels. The receiver may select (demultiplex) only packets of a desired channel in the multiplexed transport stream using the PID.

The service information table includes a service description table (SDT), an event information table (EIT) (p / f), an event information table (EIT) (sch), a broadcaster information table (BIT), a time offset table (TOT), and software (SDTT). Download Trigger Table).

The transmission system 201 sends download signaling to the terminal 203 that is wake-up from the idle state through the SDTT, that is, the terminal 203 that is powered on and is receiving or watching digital broadcasting. Send a message indicating that the channel switching screen is being sent. Here, the idle state is a state in which the power of the terminal 203 is turned on but not receiving the digital broadcast, and the wake-up means that the terminal 203 receives or views the digital broadcast. In addition, in the embodiment of the present invention, information is transmitted to an SDTT, a download content descriptor, a PMT, a stream identifier descriptor, and a carousel identifier descriptor for download signaling.

The multiplexer 307 packetizes the encoded channel switching screen output from the encoder 305 and the sectioned program designation information table and service information table output from the PSI / SI server 306 into PSI / SI tables. Output to the transport stream.

The transmitting unit 308 is a pilot channel 204, CAS channel 205, EPG channel 206, video channel 207, audio channel 208 and data channel 209 used to provide a broadcast service The broadcast channel is configured, and the transport stream is transmitted through a channel in which an idle band is generated among the broadcast channels 204 to 209.

As an example of an idle band, EPG channel 206 is a channel through which EPG information is transmitted, and EPG information indicates what kind of broadcast program is currently provided to the user, what channel is the broadcast channel, Information indicating when the start time is and when the end time is. Since the EPG information is guide information for a broadcast program, the amount of data is reduced when the broadcast program is broadcasted and terminated, so that the EPG channel 206 that transmits EPG information decreases as the afternoon time increases the idle band. The video and audio channels 207 and 208 are channels through which a broadcast program is transmitted, and an idle band may occur as a specific channel is waved at a specific time. Accordingly, the present invention is economical because it is possible to provide a channel switching screen service without allocating an additional band by transmitting a channel switching screen through an idle band. For example, broadcast channels 204 through 209, including EPG, video and audio channels 206, 207, and 208, can be changed by the operator's channel operating policy, and EPG, video and audio channels 206, 207, and 208. The channel switching screen may also be transmitted through the idle bands of other broadcast channels 204 to 209.

The channel switching screen transmitted by the transmission system 201 through the above-described process is transmitted to the receiver terminal 203 through the satellite 202 or to the receiver terminal 203 through the satellite 202 and the gap filler. The description will be simplified for the sake of simplicity and non-invention. An antenna provided in the receiver terminal 203 receives a transport stream including a channel switching screen transmitted by the transmission system 201 through the satellite 202, and the received transport stream is a converter, a CDM demodulator, and a demultiplexer. And restore through a decoder or the like. The restored channel switching screen is displayed through the display device of the receiver terminal.

Hereinafter, a method of detecting a channel switching screen from a transport stream according to an embodiment of the present invention will be described.

The channel switching screen of the present invention is provided by using a BnDS (Broadcast Network Download Service) defined in the "Multimedia Specification for Satellite DMB Terminal" (hereinafter referred to as a specification).

In order to implement the embodiments of the present invention, some matters of the specification will be revised. First, in the specification, the logo ID (Logo_ID) defines only the logo ID of the service provider and defines the logo data as the image file according to the logo ID. In an embodiment of the present invention, a logo ID (for example, Ch_Loading) is assigned to a channel switching screen, logo data according to the logo ID is defined, and a logo ID and logo data operating method according to the channel switching screen are defined. Secondly, SDTT could only be updated once a day, and the transmission system 201 did not transmit PMT and SDTT when it did not transmit the download content (in the present invention, the channel switching screen will be transmitted), and the SDTT channel It was sent only while a carousel transmitting the switching screen was being sent. For this reason, at any time, the transmission system 201 can transmit the channel switching screen through the channel where the idle band has occurred, and the terminal 203 can update the SDTT, which was only once updated once a day, so that the terminal 203 can receive it. Do it.

In order for the terminal 203 to receive the channel switching screen, the terminal 203 must be in a wake-up state from the idle state. In this case, the idle state refers to a state in which the terminal 203 is turned on but is not receiving digital broadcasting. The wake-up means a state in which the terminal 203 is receiving or watching digital broadcasting. . Accordingly, the terminal 203 according to the embodiment of the present invention receives and stores a transmission reservation table that has a startup program that starts at a predetermined cycle and announces the time when the channel switching screen is to be transmitted.

When the transmitting system 201 transmits the channel switching screen through the satellite 202, the terminal 203 in the power-on state starts up at a predetermined period through a startup program or starts at a scheduled time according to the transmission reservation table to perform SDTT. Detect. The terminal 203 that detects the SDTT can recognize that the channel switching screen is being transmitted through the channel in which the idle band is generated, and the logo ID defined in the program switching information table and the service information table, in particular, the channel switching screen with reference to the SDTT. The channel switching screen may be restored by searching for (Ch_Loading) and detecting logo data according to the searched logo ID. Therefore, according to the present invention, since the channel switching screen can be delivered to the receiver at any time according to the promotion strategy, it is possible to actively promote the broadcast program and various services.

4 is a diagram illustrating a terminal displaying a channel switching screen according to an exemplary embodiment of the present invention.

First, the transmission system 201 produces a channel switching screen to promote a broadcast program or to promote various events. The channel switching screen is made of various types of files, and one or more files, for example, 12 files are set as one set. The produced channel switching screen is transmitted to the satellite 202 by the transmission system 201 according to the schedule of the operator's advertising plan. The satellite 202 receives the channel switching screen and returns the received channel switching screen to the terminal 203 on the ground. To be sent).

The channel switching screen is transmitted through broadcast channels 204 through 209 in which idle bands occur, and the idle band may occur in all channels of broadcast channels 204 through 209. In the case of the EPG channel 206, since the program information of the broadcast program already broadcasted is not transmitted toward the afternoon, the idle band of the EPG channel 206 gradually increases as the amount of EPG decreases. In the video, audio, and data channels 207, 208, and 209, an idle band may occur due to a decrease in the amount of data during the standing time of a specific channel. Therefore, the transmission system 201 may transmit the channel switching screen by using the idle bands of the broadcast channels 204-209. Therefore, there is no need to allocate new bands, so it is economical.

The transmission system 201 also transmits the SDTT, which is a component of the service information table, every time the channel switching screen is transmitted, and the terminal 203 starts a predetermined time or a reservation time of the transmission reservation table received in advance according to the provided activation program. Start up. The activated terminal 203 receives the channel switching screen through the idle bands of the broadcast channels 204 to 209 with reference to the SDTT. Therefore, the operator may transmit the channel switching screen and the SDTT to the terminal 203 that is powered on according to the startup time, and the terminal 203 may receive the channel switching screen with reference to the SDTT, so that the necessary time according to the advertising plan of the operator You can promote on

The terminal 203 stores the channel switching screen in the temporary storage device of the receiver terminal 203 until the channel switching screen is received (the channel switching screen can be configured with one or more files, for example, 12 files). Upon receiving all the switching screens, the terminal 203 searches for the storage device of the terminal storing the channel switching screen, and if the existing channel switching screen exists, the newly received channel switching screen is overwritten on the existing channel switching screen. If there is no existing channel switching screen, the terminal 203 stores the received channel switching screen in the storage of the terminal. If the receiver selects another broadcast channel while watching the broadcast program (a), a loading time of 3 to 8 seconds is required to load another channel, but the terminal 203 displays the stored channel switching screen (b) during the loading time. Display through the display device of the terminal.

The channel switching screen can be composed of one set of 12 files, and the number of files can be increased or decreased as needed. In addition, each file channel switching screen may be arranged and used at different loading times according to a plan. For example, the channel switch screen used to change channels from video channels to audio channels, the channel switch screen used to change channels from audio channels to premium channels, and the channel switch used to change channels from audio channels to video channels. The screens may be different, and the channel switching screens displayed may vary according to time.

5 is a view for explaining a method for a receiver terminal to display a channel switching screen on the display device of the terminal according to an embodiment of the present invention.

The operator produces a channel switching screen according to the advertising strategy, and the transmission system 201 stores the channel switching screen and broadcasts the channel switching screen, the program designation information table, and the service information table according to a predetermined schedule. Transmit over channels 204-209. At this time, the SDTT, which is a component of the service information table, is transmitted together to notify the terminal 203 that the channel switching screen is being transmitted (S001).

In order to receive the channel switching screen, the terminal 203 starts up at a predetermined period through the start program or starts up at a reserved time of the transmission reservation table and leaves the idle state. In addition, when the mobile terminal 203 is released from the idle state and detects the SDTT, the terminal 203 recognizes that the channel switching screen is being transmitted (S002).

Recognizing the channel switching screen, the terminal 203 receives a program designation information table and a service information table together with the channel switching screen (S003).

The terminal stores the channel switching screen (one set of twelve image files) in the temporary storage device of the receiver terminal 203 (S004).

Upon receiving all one set of channel switching screens, the terminal 203 searches the storage device of the channel switching screen of the terminal and, if an existing channel switching screen exists, overwrites one set of newly received channel switching screens on the existing channel switching screen ( And overwrite) to update and save the channel switching screen, and if there is no existing channel switching screen, store one set of the received channel switching screen in the storage device of the terminal (S005 to S007).

The receiver can watch various channels provided by digital broadcasting through the terminal, and if the receiver selects a broadcasting channel to watch the broadcasting channel, it needs 3 to 8 seconds of loading time to load the broadcasting program, and the receiver can select a specific channel. If you select another channel to watch another channel's broadcast while watching the program of, it takes 3 to 8 seconds to load another channel. In this case, the terminal 203 displays the stored channel switching screen through the display device of the terminal during the loading time (S008, S009). Therefore, by servicing various channel switching screens during the channel loading time, it is possible to relieve the boredom of the receiver, thereby reinforcing the royalties of customers and increasing the publicity effect by advertising using the loading time.

As described above, according to the present invention, there is no need to allocate an additional band by transmitting a channel switching screen through an idle band of a broadcast channel, and various channel switching screens can be promoted according to an event and an advertising plan of a service provider. For example, you can increase customer royalties by advertising during tedious channel loading times. Therefore, it is economical and can enhance the promotional effect of various events and broadcasting programs and create new business models.
