Description

Apparatus including a smart satellite antenna capable of multicasting and artificial intelligence-based voice recognition auto-tracking and method of operation

The present invention relates to an apparatus including a satellite antenna and a method of operating the same. More specifically, the present invention relates to an apparatus including an outdoor smart satellite antenna capable of receiving satellite broadcasts in outdoor areas such as a car, a camper, or a yacht and conveniently providing it to a user, and an operating method thereof.

In a satellite broadcasting (Broadcasting Satellite, BS) system, a satellite relays a broadcast signal transmitted by a terrestrial broadcasting station, and a user receives and uses a broadcasting signal using a terrestrial satellite antenna and a satellite broadcasting receiver.

In order to search for a channel that a user wants to watch, unlike a typical TV receiver, it is not enough to simply tune the frequency of a wired/wireless channel. must be moved or rotated. In general, a satellite antenna is a directional antenna.

A process in which a satellite broadcast receiving apparatus motorizes a satellite antenna in order to search for and view a satellite channel desired by a user is disclosed in Korean Patent Laid-Open Publication No. KR 10-2015-0043876 "Method and Apparatus for Searching a Satellite Channel".

The satellite antenna of the prior document KR 10-2015-0043876 is manufactured assuming use in a specific area on the earth. Since the number of satellites that can be viewed is limited in a specific region on the earth, movement and rotation of the satellite antenna are performed within a very limited range in KR 10-2015-0043876 and the like.

Meanwhile, recent modern people want to enjoy various leisure activities, and camping and leisure activities are in the spotlight as one of the ways to enjoy leisure. In such a space, normal terrestrial broadcasting is difficult in some cases, and therefore, the demand for a satellite broadcasting receiver capable of watching satellite broadcasting in such an outdoor field is increasing.

However, the outdoor satellite broadcasting receiver cannot respond to various demands because it is manufactured on the assumption that it is used only in a specific area on the earth. Therefore, the movement and rotation of the satellite antenna in a wider range should be guaranteed. For this, the present applicant has proposed Korean Patent KR 10-2031250 "Auto-tracking antenna for simultaneous reception of satellite and terrestrial waves having a 360-degree azimuth rotation structure".

In a broadcast reception and display device, a display control technology using voice recognition has recently been proposed to conveniently help a user select a channel and view broadcast content. For example, Korean Patent Laid-Open Patent KR 10-2017-0087712 "Display Apparatus and Controlling Method of Display Apparatus" and US Patent Registration US 10,779,030 "Display Apparatus and Controlling Method Thereof" may be mentioned.

However, unlike in general urban facilities or homes, in outdoor sites, the radio wave environment is poor, and computing power or power supply is not sufficient. Considering this, the technology for providing user convenience by voice recognition is improved for the outdoor site. Attempts to optimize still need to be continued.

On the other hand, in recent years, due to the development of wireless communication technology, since most of the smart devices are brought to outdoor sites, there is a demand for a technology that can share satellite broadcasting contents with nearby wireless devices or smart devices using wireless communication technology. exists

Korean Patent Publication KR 10-2018-0109340 "Electronic Device and Screen Sharing Method of Electronic Device" and US Patent Publication US 2020/0057589 "ELECTRONIC DEVICE AND SCREEN SHARING METHOD OF ELECTRONIC DEVICE" disclose two devices having different screen sizes. A technique for sharing content displayed on a screen through a wireless channel by pairing is disclosed.

However, KR 10-2018-0109340 and US 2020/0057589 focus on computing for adjusting image data in consideration of screen sizes between different devices. Therefore, it consumes considerable computing power, and it is a technology difficult to apply as it is in the outdoor field where available computing power is limited.

Meanwhile, in Korean Patent KR 10-2139107 "System and method for providing broadcast data mirroring service for smart TV and smart phone receiving multi-channel broadcast signal", a set-top box for receiving multi-channel broadcast signal is used for broadcasting of smart TV and smart phone. We propose a service that mirrors data.

However, the KR 10-2139107 is actually MPEG-encoded for IPTV or smart TV and downloaded in advance, MPEG-decoded broadcast content stored in the set-top box is MPEG-encoded again to a different screen standard for the smart phone and provided to the smart phone. As such, it is difficult to satisfy the demand for simultaneously providing real-time broadcast content. The KR 10-2139107 consumes a lot of computing power during MPEG encoding, and for this purpose, there is a problem in that the set-top box must have a storage having a large storage space.

On the other hand, another demand required in the outdoor field is, for example, a communication device that can generate an alarm or a rescue request when an emergency is detected, so as to provide a prompt and appropriate response in case of an unexpected event or accident. can be heard

In general urban facilities or homes, they have sufficient power and communication facilities, and have relief measures to respond to incidents and accidents, but in outdoor sites, the ability to respond to the same incidents and accidents is inevitably weak. .

In response to this demand, the present applicant has proposed Korean Patent Registration KR 10-1879254 "Satellite broadcast reception TV that generates an alarm by detecting an accident".

However, attempts to further improve and optimize the emergency detection and response process in the outdoor field in consideration of user convenience still need to be continued.

Hereinafter, details of the present invention will be described with reference to the embodiments of FIGS. 1 to 4 .

1 is a diagram showing an outline of a smart satellite antenna device for outdoor use in the technical field of the present invention.

Referring to FIG. 1 , the artificial satellite 110 may be used to transmit a broadcast. In this case, the satellite 110 may receive a satellite broadcast signal from a terrestrial broadcasting station and retransmit the satellite broadcasting signal to receiving devices on the ground.

The satellite broadcast reception system includes a satellite broadcast reception antenna 130 , a satellite broadcast reception device (not shown), and a display device 140 . The satellite broadcast reception antenna 130 is generally a directional antenna. Therefore, it is necessary to adjust the satellite broadcast reception antenna 130 to face the direction of the satellite before receiving the satellite broadcast.

The satellite broadcast receiving system may be mounted on the vehicle 120 as shown in FIG. 1 . In this case, the direction of the satellite broadcast reception antenna 130 may be changed as the direction of the vehicle 120 is changed. Even when receiving satellite broadcasting after parking the vehicle 120 , if the parking direction of the vehicle 120 is changed, the direction of the satellite broadcasting reception antenna 130 must be readjusted to receive satellite broadcasting.

However, it is cumbersome to adjust the direction of the satellite broadcast reception antenna 130 every time, and it is not easy for general users to precisely adjust the direction of the satellite broadcast reception antenna 130 in the direction of the satellite that transmits the channel they want to receive. That's a problem.

Although the direction of the satellite broadcast receiving antenna 130 may be automatically controlled to the direction of the satellite, the user interface for this is complicated, and general users still have problems in receiving satellite broadcast using the satellite broadcast receiving antenna 130 . come.

As an example of an effort to improve the process of receiving satellite broadcasting using the satellite broadcasting reception antenna 130, Korean Patent Laid-Open Publication No. KR 10-2015-0043876 "Method and Apparatus for Searching Satellite Channels" and Korean Patent Registration KR 10 - 2031250 "satellite and terrestrial wave simultaneous reception auto-tracking antenna having a 360-degree azimuth rotation structure" has been disclosed, and some of the configurations of the prior documents may be applied to the present invention within the scope consistent with the object of the present invention.

2 is a diagram illustrating a smart satellite broadcast reception system for outdoor including a smart satellite antenna device for outdoor use in the technical field of the present invention.

Figure 2 discloses a configuration that requires a set-top box separately from the antenna controller (box) as a comparative example of the present invention. 2 is not consistent with the prior art for the present invention recognized under the Patent Act, and those skilled in the art will clearly recognize that it is a comparative example constructed to help the understanding of the present invention.

In the comparative example of FIG. 2 , the satellite broadcast receiving system requires a separate set-top box in addition to the controller (antenna control box) for controlling the satellite tracking antenna. There is a wired connection between the satellite tracking antenna and the controller. The set-top box is also connected to the satellite tracking antenna by wire, and the TV monitor and the set-top box are also connected by wire. The remote controller works in conjunction with the set-top box to affect the content displayed on the TV monitor. This method is a comparative example in which broadcasting can be viewed only inside the vehicle using a TV monitor connected by wire.

On the other hand, in the comparative example of FIG. 2, Korean Patent Application Laid-Open Patent KR 10-2018-0109340 "Electronic Device and Screen Sharing Method of Electronic Device", US Patent Publication US 2020/0057589 "ELECTRONIC DEVICE AND SCREEN SHARING METHOD OF ELECTRONIC DEVICE", and/or Korean Patent No. KR 10-2139107 "System and method for providing broadcast data mirroring service for smart TV and smart phone receiving multi-channel broadcast signals" It can be implemented only on the premise that it is performed in a box. The contents disclosed in the prior documents require a significant level of computing power, and because the storage having a large storage space is essential, a person skilled in the art cannot implement the configuration disclosed in the prior documents without a separate set-top box. It will be apparent to those skilled in the art.

The present invention does not necessarily require a separate set-top box, and provides a function of forming a multicasting network in the controller of the satellite tracking antenna without a separate set-top box. Hereinafter, the controller of the smart satellite antenna device and the multicasting network streaming service of the present invention will be described in detail with reference to FIGS. 3 and 4 .

3 is a diagram illustrating an embodiment of providing a multicasting streaming service using a smart satellite antenna device for outdoor use according to an embodiment of the present invention.

4 is a diagram illustrating a smart satellite antenna device for outdoor that can provide a multicasting streaming service and a system including the device according to an embodiment of the present invention.

3 and 4 , the satellite tracking smart antennas 330 and 430 are connected to the controller 450, and the controller 450 may include at least one processor, memory, and/or storage therein. . In addition, the multicasting streaming service using the smart satellite antenna of the present invention may be provided to the outdoor site in the form of computer-readable program instructions, and the multicasting streaming service is provided in which the program instructions are stored in at least one processor and/or memory. It can be provided to the user by being stored or loaded and executed by the user.

Controller 450 corresponds, for example, to a computing system (not shown), which may include a processor, memory, storage, database, and/or communication interface module. The following operations and functions are performed by a processor in the computing system, and the processor may perform the following operations and functions in cooperation with at least one of a memory, a storage, a database, and/or a communication interface module.

The smart satellite antenna device of the present invention may be configured to include satellite tracking antennas 330 and 430 and a controller 450 .

By the controller 450 , the satellite broadcast content received via the satellite tracking smart antenna 330 is provided to the display device inside the vehicle via the wired link 362 or via the wireless links 364 and 366 . It may be provided as a wireless device or a smart device possessed by the user.

At this time, the provision of satellite broadcast content via the wire link 362 is the same as the broadcast service shown in the comparative example of FIG. 2 , and the multicasting disclosed in the present invention excludes broadcast streaming via the wire link 362 . It will be apparent to those skilled in the art that the concept of

The multicasting service is provided to a wireless device or smart device possessed by a user via a wireless link 364, 366, and may be executed and optimized by the controller 450 of the present invention. Accordingly, the user can wirelessly watch the satellite broadcast using the smart device even outside the vehicle. At this time, the controller in order to synchronize or minimize the time difference between the satellite broadcast content provided via the wired link 362 and the objects of the multicasting network provided via the wireless link 364 through the TV display connected by wire inside the vehicle. By 450 the multicasting network may be optimized or timing conditions may be adjusted.

According to the smart satellite antenna apparatus of the present invention, the controller 450 receives a satellite broadcast signal via the satellite antennas 330 and 430, and directly transmits satellite broadcast streaming without a separate set-top box to nearby wireless devices/smart devices. It is shared with the ones (442, 444). At this time, the wired link 362 is not included in the multicasting network, but satellite broadcast streaming may be shared between the wired link 362 and the multicasting network based on the wireless links 364 and 366 .

In that the controller 450 of the present invention forms a wireless multicast network 364, 366 with the surrounding wireless devices/smart devices 442 and 444, it is also differentiated from the comparative examples in the prior literature or FIG. .

The satellite signal receiver 451 in the controller 450 receives a satellite broadcast signal through the satellite tracking smart antenna 430 .

The display transmitter 452 in the controller 450 may convert the received satellite broadcast signal into content data and transmit it to the TV 440 via the wired link 362 .

Specific operations of the satellite signal receiver 451 and the display transmitter 452, and/or the smart satellite antennas 330 and 430 via the controller 450 so that the user can receive the desired satellite and satellite broadcasting channels. Among the moving and rotating technologies, the above-mentioned Korean Patent Publication KR 10-2015-0043876 "Satellite channel search method and apparatus", Korean Patent KR 10-2031250 "Satellite and terrestrial wave simultaneous reception auto-tracking having a 360 degree azimuth rotation structure" Antenna", Korean Patent Laid-Open Patent KR 10-2017-0087712 "Display Device and Control Method of Display Device", US Patent Registration US 10,779,030 "Display Apparatus and Controlling Method Thereof", Korean Patent Publication KR 10-2018-0109340 "Electronic Device and Screen sharing method of an electronic device", US Patent Publication US 2020/0057589 "ELECTRONIC DEVICE AND SCREEN SHARING METHOD OF ELECTRONIC DEVICE", Korean Patent KR 10-2139107 "Broadcasting data of a smart TV and smartphone receiving multi-channel broadcasting signals A system and method for providing a mirroring service", and/or Korean Patent Registration KR 10-1879254 "Satellite broadcast reception TV generating an alarm by detecting an accident", etc., which are known to those skilled in the art, replace the description of the present invention.

In addition, the display transmitter 452 may convert the received satellite broadcast signal into content data and transmit it to the multicast transmitter 456 .

The wireless terminal recognition unit 454 recognizes the wireless devices/smart devices 442 and 444 of at least one or more users who want to watch satellite broadcasting, and the user who wants to watch the satellite broadcasting in the multicasting network control unit 455 . Identification information of the wireless devices/smart devices 442 and 444 of .

At this time, in addition to the remote controller, any one of the user's wireless devices/smart devices 442 and 444 can be designated as the master, and a multicasting related command is input to the master terminal, and multicasting related by an application program installed in the master terminal. A multicasting network service may be provided by transmitting the command to the controller 450 . Whether multicasting for the user's wireless devices/smart devices (442, 444) as well as the driving and auto-tracking of the satellite antenna by inputting commands related to whether to execute multicasting, designation of a multicasting target terminal, etc. to the master smart terminal , and a command for designation of a multicasting target may be transmitted to the controller 450 .

The multicasting network control unit 455 is based on the identification information of the user's wireless devices/smart devices 442 and 444 of the user who wants to watch the satellite broadcast, and the user's wireless devices/smart devices 442 and 444 and It is possible to manage/control the formation of a multicasting network. That is, the multicasting network control unit 455 may distribute or allocate a bandwidth for multicasting streaming with the wireless devices/smart devices 442 and 444 of the user who wants to watch the satellite broadcast.

In addition, the multicasting network control unit 455 may determine the bandwidth of data to be shared streaming within the frequency band prescribed by the Wi-Fi standard based on the screen size of each smart device and the number of smart devices.

The multicasting network control unit 455 is a frequency band defined by the Wi-Fi standard, and a frequency bandwidth that can be used in consideration of the situation in the field, the number of nearby wireless terminals and smart terminals, and screens of each of the nearby wireless terminals and smart terminals A target bandwidth of a digital data stream converted from a satellite broadcast signal may be set in consideration of the size.

In at least one or more of the embodiments of the present invention, the multicasting network control unit 455 mirrors the broadcast signal M1 displayed through the TV toward the plurality of smart terminals 442 and 444 wireless multicasting link/network. Set (364, 366), the broadcast signal (M1) may be multicast toward a plurality of smart terminals (442, 444) through the wireless link (364, 366).

The multicasting network control unit 455 groups terminals having the same specifications for multicasting such as screen standards among nearby wireless terminals and smart terminals, and controls the multicasting network between the controller 450 of the satellite antenna and a plurality of terminals in one group. can be formed In this case, a plurality of terminals in one group may share the same Wi-Fi frequency band, and this technique may reduce the required Wi-Fi frequency bandwidth.

For example, among smart terminals A, B, and C, if A and B use a single frequency channel and C uses a different frequency channel, multicasting can be performed to three devices using only two Wi-Fi frequency channels. . At this time, when smart terminals A and B receive satellite broadcast streaming via one Wi-Fi channel, when terminal A or B sends a message to the controller of the satellite antenna, a separate channel is used in addition to the satellite broadcast streaming channel. By setting it to use, the multicasting network can be managed so that the privacy between terminals A and B is not violated. Specifically, when two or more terminals share one broadcast streaming channel, this channel is a one-way channel, and data is transmitted only from the controller to the terminal, and when a signal is transmitted from the terminal to the controller through the broadcast streaming channel, the minimum Only messages of , for example, ack messages, can be transmitted in the reverse direction.

At this time, the satellite broadcast streaming occupies a fixed bandwidth, for example 100 MHz bandwidth. When such satellite broadcast streaming is delivered via the wireless links 364 and 366 without compression, it occupies a very large amount of wireless bandwidth. Even if compression including MPEG encoding is performed, the wireless bandwidth for streaming satellite broadcasting is generally larger than that of a wireless communication channel for sending and receiving normal messages. Accordingly, in the present invention, an appropriate sharing-enabled group is formed in consideration of the characteristics of a wireless terminal, and the same frequency band is set for terminals in the group to perform multicasting of satellite broadcasting streaming. At this time, for stable and synchronized (or minimized time difference) satellite broadcasting streaming sharing, it is advantageous that the bandwidth over which multicasting is made is unilateral streaming from the controller 450 to the terminals in the group. Therefore, when at least one or more of the terminals in the group need to transmit a message to the controller 450 for network setup, control, and management, it is possible to implement a separate wireless communication channel (with a much smaller bandwidth than a multicasting network for streaming) ) can be used to send messages.

On the other hand, in another embodiment of the present invention, the satellite signal receiver 451 can receive two satellite broadcast channels even by a single reception setting due to vertical / horizontal components when receiving satellite broadcast by a single tuner. In the wireless devices/smart devices (442, 444), a channel can be selected from the respective application menu, and the multicast object is a signal of the selected channel from each of the wireless devices/smart devices (442, 444). may be a digital data stream converted from .

Due to the characteristics of satellite broadcasting, when the channel M1 is selected for TV and auto-tracking is performed so that the satellite can receive M1, M2 may also be provided to the user in the present invention based on the vertical/horizontal component of M1. That is, the TV may display M1, and the plurality of smart terminals may display M1 or M2. In this case, the group sharing the same channel of the multicasting network may be determined in consideration of the characteristics of the terminal, the channel selected by the terminal (whether M1 or M2), and the positional relationship with the controller.

At this time, in at least one or more of the embodiments of the present invention, whether multicasting is executed by the controller of the present invention and/or the result of designating a plurality of terminals as a target of multicasting determined by the controller of the present invention is to be fed back to the satellite. No need. Designation of a plurality of terminals as a target of multicasting determined by the controller of the present invention whether multicasting is performed by the controller of the present invention and/or may be dynamically made in the field. That is, based on the interaction with the user terminal, the controller can determine whether to multicast in the field, and based on the interaction with the user terminal, the controller can freely add or remove the terminal as a multicasting target. In this case, whether multicasting is executed and the result of designation of the terminal as a multicasting target may not affect the contents of a satellite broadcast stream received from the satellite. In other words,. Whether or not multicasting is executed and the result of designation of the terminal as a multicasting target can be dynamically executed in the field regardless of satellite and satellite broadcasting providers.

When the target of multicasting is dynamically changed in the field, the controller 450 may adjust timing conditions for synchronization with the added terminal, the terminal already included in the multicasting target, and the TV display. At this time, if complete synchronization is difficult, the controller of the present invention may adjust at least one timing condition of the first broadcast streaming transmitted to the display and the second broadcast streaming transmitted to the wireless terminal so that the playing time difference between the terminal and the display is within the reference value. have.

Also, the controller 450 may adjust a timing condition of at least one of each of the broadcast streams transmitted to the plurality of terminals so that the playing time difference between the broadcast streams transmitted to the plurality of terminals is within a reference value.

On the other hand, the multicasting network controller 455 controls the bandwidth of data to be shared streaming within the frequency band used in other wireless LAN technologies, that is, Bluetooth, etc., as well as the frequency band stipulated in the Wi-Fi standard for each smart device It can be determined based on the screen size and the number of smart devices.

The multicasting transmission unit 456 receives the satellite broadcasting streaming data as content data from the display transmission unit 452 , and the user's wireless devices/smart devices 442 and 444 transmitted by the multicasting network control unit 455 . ) according to the Wi-Fi bandwidth information allocated to each, it is possible to share streaming satellite broadcasts with nearby smart devices directly through a wireless link channel.

In at least one or more of the embodiments of the present invention, the multicasting transmitter 456 may not necessarily perform MPEG encoding on the satellite broadcast streaming data. Accordingly, time and/or computing power is not consumed for image scaling and/or MPEG encoding as in the prior art, and real-time image sharing can be maintained.

In another embodiment of the present invention, MPEG encoding may be partially performed when the number of smart devices to be received increases. In this case, if compression such as MPEG encoding is not performed at all, Wi-Fi bandwidth is occupied a lot, and the number of smart devices that want to share the screen may be limited. Since Wi-Fi bandwidth is not an unlimited resource, in some embodiments of the present invention, MPEG encoding may be selected according to circumstances.

In this case, the multicasting transmitter 456 may perform image scaling or MPEG encoding on the satellite broadcast stream data in consideration of the screen standards of satellite broadcasts such as SD, HD, and UHD, and the screen standards of each smart device.

Meanwhile, the satellite signal receiver 451 or the display transmitter 452 may transmit a control signal among the satellite received signals to the voice recognition controller 453 .

The voice recognition control unit 453 may control the operation of the satellite antenna so that the user's voice corresponding to the channel the user wants to watch can be recognized and the satellite broadcast signal can be received from the satellite corresponding to the corresponding channel.

The voice recognition control unit 453 combines with the satellite antenna auto-tracking technology based on voice recognition and recognizes the voice through the microphone of the remote controller that is basically provided with the satellite antenna, thereby driving and auto-tracking the satellite antenna. can be implemented

The implementation of artificial intelligence voice recognition-based satellite antenna auto-tracking technology is described in Korean Patent Application Laid-Open No. KR 10-2015-0043876 "Satellite Channel Search Method and Apparatus", Korean Patent KR 10-2031250 "Satellite and terrestrial waves having a 360-degree azimuth rotation structure. Simultaneous reception auto-tracking antenna", Korean Patent Application Laid-Open No. KR 10-2017-0087712 "Display device and control method of display device", US Patent US 10,779,030 "Display Apparatus and Controlling Method Thereof" It can be implemented by borrowing and modifying it to meet the purpose of the present invention. It replaces the description of the present invention as listing the prior documents.

In addition, the voice recognition control unit 453 recognizes the user's voice by an artificial intelligence-based voice recognition technique, so that the wireless terminal recognition unit 454 surrounds the user's wireless devices/smart devices 442 and 444 . A voice recognition interface may be provided to recognize In this case, the voice recognition control unit 453 is combined with the satellite antenna auto-tracking technology based on the voice recognition technology, and by recognizing the user's voice, not only the driving and auto-tracking of the satellite antenna, but also wireless devices/smart devices of the user in the vicinity. A voice recognition-based user interface capable of inputting commands for whether to multicast for the devices 442 and 444 and designation of a multicasting target to the controller 450 based on voice recognition may be provided.

At this time, in addition to the remote controller, any one of the user's wireless devices/smart devices 442 and 444 can be designated as the master, and the voice command is input to the master terminal, and voice recognition is performed by the application program installed in the master terminal. can Therefore, by inputting a voice command to the master smart terminal, not only the driving and auto-tracking of the satellite antenna, but also the user's wireless devices/smart devices (442, 444) for multicasting, and the command for the designation of the multicasting target can be passed to the controller.

It is assumed that at least one or more of the embodiments of the present invention does not include a separate set-top box (STB) and performs some functions of the set-top box in the satellite antenna controller. In another embodiment of the present invention, a separate set-top box may be included, but the separate set-top box additionally performs functions such as user authentication for viewing paid content, and/or content restriction for child protection. assume that

The present invention assumes that the computing power of the controller is limited for this reason, and is a screen sharing technology optimized for insufficient computing power and Wi-Fi bandwidth.

In addition, since the present invention is a multicasting technology of real-time satellite broadcasting that shares real-time satellite broadcasting with other smart devices, it is a prior art in that elements not suitable for real-time sharing are boldly excluded and only essential components are adopted. It is differentiated from the comparative example of FIG.

Although multicasting is often referred to in prior literatures in the field of IPTV or satellite broadcasting, multicasting in the prior art introduces the concept in which, for example, in an IPTV service, a broadcast server to a subscriber set-top box is composed of a wired multicast network, It's just a backwards compatible concept of broadcast.

On the other hand, in the present invention, the controller 450 of the satellite antennas 330 and 430 recognizes the surrounding wireless device/smart devices 442 and 444, and wireless multi It is differentiated from the prior arts and the comparative example of FIG. 2 in that the cast networks 364 and 366 are formed.

In addition, the present invention is different from the concept of providing a multicasting service to subscribers who have previously subscribed to a wired or wireless service. Multiple terminal assignments need not be fed back to the satellite. In an embodiment of the present invention, multicasting and selection and designation of a plurality of terminals that are targets of multicasting may be dynamically performed in the field. That is, the user can select whether to multicast in the field, and can freely add or remove a terminal as a multicasting target. Whether or not multicasting and terminal designation may not affect the content of a satellite broadcast stream received from a satellite. Whether or not multicasting and terminal designation can be made freely and dynamically based on the interaction between the controller 450 and the user in the outdoor field independently of the providers of satellite and broadcast content.
