Description

[0001] APPARATUS AND METHOD FOR PROVIDING BROADCAST SERVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast communication technology, and more particularly, to a broadcast service providing technique using channel switching.

Currently, the cable broadcasting network in which the broadcasting service is provided is a hybrid fiber and coax (HFC) structure. Currently, various services such as an 8VSB broadcasting service as well as a large-capacity new broadcasting service such as an analog broadcasting service, a digital broadcasting service, a communication service, and a UHD broadcasting service are provided through a cable broadcasting network. However, the service provision through the transmission system based on the existing Guangdong axis hybrid network is insufficient in frequency to provide a broadband broadcasting service such as convergence, intelligence, broadcasting communication service evolving in a personalized form, and multi-point service. In order to solve the shortage of frequency resources, various methods are considered as follows.

First, it is a frequency expansion plan. By using the extended frequency band over the existing available frequency band, it is possible to extend the physically usable frequency to provide a new service, but it has a disadvantage that the network and transmission equipment must be replaced.

Second, it is a method to use high-order modulation and demodulation. Higher order modulation and demodulation can transmit more data than the currently used modulation and demodulation method. Higher-order modulation and demodulation can solve the problem of frequency shortage by increasing the total data amount that can be transmitted per reference time by increasing the transmission efficiency, but it has a disadvantage that the currently used terminal must be replaced.

Therefore, it is necessary to devise a method to solve the problem of insufficient frequency while minimizing the replacement of existing network and terminal. At present, the broadcasting service adopts a method of transmitting unilaterally regardless of whether the viewer is watching or not.

In this case, in order to reduce frequency waste, the channel switching method can efficiently use a frequency by using an idle frequency not viewed by a viewer as a channel for providing a communication service. That is, the channel switching method can be used by changing the idle broadcast channel frequency that is not used to the communication channel frequency.

For example, in order to provide RoIP service as a channel switching method, a message configuration and operation method for controlling between RoIP headend and RoIP terminal should be provided.

In order to use the channel switching method, the RoIP service needs information such as the idle frequency, the idle frequency band, and the usable time considering the distance from the CM (Cable Modem). At this time, the RoIP service needs to devise a method of configuring and operating a control message including the above information.

The present invention proposes an apparatus and a method for providing a broadcast service capable of solving a frequency problem that is insufficient by effectively using a frequency while compensating for disadvantages of network and terminal replacement and the like.

The present invention will now be described in detail with reference to the accompanying drawings. Hereinafter, a repeated description, a known function that may obscure the gist of the present invention, and a detailed description of the configuration will be omitted. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Accordingly, the shapes and sizes of the elements in the drawings and the like can be exaggerated for clarity.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a system for providing a RoIP broadcast service according to an embodiment of the present invention.

Referring to FIG. 1, there is shown a system for providing a RoIP broadcast service according to an embodiment of the present invention.

A Radio Over Internet Protocol (RoIP) broadcast service providing system may include a terminal apparatus 10 and a broadcast service providing apparatus 100.

At this time, the terminal device 10 may correspond to a RoIP terminal.

At this time, the broadcast service providing apparatus 100 may correspond to a RoIP headend.

The RoIP terminal on the subscriber side can be connected to the RoIP head end through the optical cable TV transmission network. In a Fiber To The Home (FTTH), broadcast signals and signals output from a CMTS (Cable Modem Termination System) may correspond to RF signals of different center frequency bands. The RF signals can be bundled into one output in a combiner. The combiner outputs an RF signal and can convert the RF electrical signal to an optical signal through a downstream optical transmitter. Unlike a passive optical network (PON) method in which a light source is turned on / off according to a bit value in units of bits, the converted optical signal is amplified by optical AM (Amplitude Modulation), which changes the intensity of a light source with respect to the amplitude of an RF signal. May correspond to a modulation signal. The signal converted into the optical signal can be amplified by an optical amplifier (Erbium-doped fiber amplifier, EDFA) and then transmitted to a splitter through an optical cable. Signals branched by 1: N in the branching machine can be inputted into the ONT (Optical Network Terminal) in the house.

The RoIP terminal can perform the ONT (Optical Network Terminal) function used in the PON-based optical communication and can restore the optical modulated downlink RF signal.

At this time, the RoIP terminal detects and digitizes the uplink RF signal output from the part to be transmitted to the coaxial cable equipment and the STB (Set-Top Box) or the CM (Cable Modem), and can transmit it as an IP packet.

Unlike the downstream signal, the RF upstream signal transmitted from the CM on the subscriber side can be converted into a digital signal by the RoIP terminal and transmitted to the IP network (xPON network) in the form of an IP packet.

The RoIP headend can recover the digital signal of the received IP packet to the original analog RF signal form and transmit it to the CMTS.

At this time, the RoIP headend can transmit an uplink signal in a time interval allocated by the CM from the CMTS.

To this end, the RoIP headend can be synchronized between the CMTS, the RoIP terminal and the CM. Ultimately, RoIP headend and RoIP terminal can use RF signal-based broadcasting equipment used in cable broadcasting networks such as existing subscriber STB and CMTS.

In order to apply the channel switching concept to the RoIP broadcast service providing system, a message configuration and a method for controlling the RoIP head end and the RoIP terminal are required.

In order to apply the channel switching concept to the RoIP broadcast service providing system, it is necessary to control and manage the frequency and time first.

2 is a block diagram of a broadcast service providing apparatus according to an embodiment of the present invention.

2, an apparatus 100 for providing a broadcast service according to an exemplary embodiment of the present invention includes a communication unit 110, an identification unit 120, and an allocation unit 130.

The communication unit 110 receives a data packet from the viewer's terminal device 100 via the IP network, converts the digital packet of the data packet into an analog signal, and transmits the converted analog signal to the CMTS.

At this time, the communication unit 110 can receive the broadcast service request of the viewer and deliver it to the confirmation unit 120.

The confirmation unit 120 can receive at least one of the viewer's newness, idle frequency, and idle channel service status of the viewer of the broadcast channel selected by the viewer by receiving the broadcast service request from the viewer.

At this time, the confirmation unit 120 confirms whether or not the viewer is new. If the viewer is an existing viewer, the confirmation unit 120 requests the allocation unit 130 to cancel the allocation of the broadcast channel viewed by the existing viewer, You can check if the channel is idle.

At this time, the confirmation unit 120 may check the viewer count value of the broadcast channel, and if the viewer count value is 0, the frequency of the broadcast channel may be confirmed as the idle frequency.

At this time, the viewer count value CNT may correspond to the viewer selected channel count value CNT.

At this time, the confirmation unit 120 can confirm the viewer count value (CNT) of each pre-allocated broadcasting channel managed by the DB server or the internal DB.

If the viewer count value (CNT) is 0, the corresponding channel is an idle frequency for which no service is provided, so that the corresponding broadcasting channel can provide communication service.

At this time, the confirmation unit 120 confirms whether the viewer is new or not, and if the viewer is a new viewer, the confirmation unit 120 can check whether the broadcast channel is idle.

In this case, when the frequency of the broadcast channel is an idle frequency, the confirmation unit 120 requests the allocation unit to allocate a viewer to the broadcast channel. If the frequency of the broadcast channel is not an idle frequency, Can be confirmed.

The allocator 130 allocates the viewer to the frequency of the broadcast channel based on a result of checking at least one of whether the viewer is new, idle frequency, or idle channel service, and provides the broadcast service of the broadcast channel have.

At this time, if the viewer is an existing viewer, the allocation unit 130 can cancel the allocation of the broadcasting channel viewed by the existing viewer.

In this case, if the viewer is a new viewer and the frequency of the broadcast channel is an idle frequency, the allocator 130 may assign the viewer to the broadcast channel.

In this case, when the frequency of the broadcast channel is not the idle frequency and the service of the broadcast channel is the idle channel service, the allocator 130 allocates a viewer to the broadcast channel after terminating the idle channel service, When the service of the channel is not the idle channel service, the viewer can be allocated to the broadcast channel.

At this time, the idle channel service may correspond to the communication service being provided in addition to the broadcasting service at the frequency requested by the viewer.

At this time, the allocator 130 decrements the viewer count value pre-allocated to the broadcast channel to cancel the allocation of the viewer allocated to the broadcast channel, increases the viewer count value to the broadcast channel, Can be assigned.

For example, when the allocation of an existing viewer is canceled, the allocation unit 130 may decrease the viewer count value CNT by one, and increase the viewer count value CNT by 1 when allocating a new viewer .

Table 1 is a table showing a broadcast service request message and an audio channel assignment message according to an embodiment of the present invention.

Referring to Table 1, a broadcast service request message (REQ message) may include a subscriber identifier (ID), a current viewing channel identifier (Current_CH_ID), and a viewing request channel identifier (Request_CH_ID).

At this time, the RSP message may include a subscriber identifier (ID), a viewing request channel identifier (Request_CH_ID), and a viewing channel allocation (assign_ch).

Referring to Table 1, in order to manage and control a viewer and a channel requested for a broadcasting service, an identifier (subscriber_ID) capable of identifying a subscriber (viewer) requesting a broadcasting service first is required.

At this time, the confirmation unit 120 can confirm important information such as the CM version of the subscriber, the distance from the current location to the viewer, etc. from the server or the database that manages the subscriber information using the subscriber identifier of the received broadcast service request message .

For example, when the broadcasting service providing apparatus 100 displays a reference time for providing the service, the broadcasting service providing apparatus 100 may reflect the error according to the distance to the terminal device 10 of the viewer.

At this time, the confirmation unit 120 needs a current viewing channel identifier (current_ch_ID) that can identify the current viewing channel in order to check whether there is a broadcasting channel that the viewer requesting the service currently has. At this time, if the current viewing channel identifier does not have a current viewing channel, the user can input 000 value.

At this time, the identifier (request_ch_ID) of the channel requested by the viewer to watch may correspond to the identifier of the channel to be viewed.

At this time, the confirmation unit 120 can confirm whether the channel to be viewed is a channel in which an existing service is provided or a new channel.

At this time, the allocator 130 may increase the viewer count value (CNT) of the channel to be watched and then perform channel assignment (assign_ch) to the subscriber.

In addition, the allocator 130 may inform the viewer of the time available for providing the service in order to provide the communication service such as uploading the upward data of the viewer through the broadcast channel of the idle frequency.

At this time, the assigning unit 130 notifies the viewer of the time available for providing the service, so that the idle frequency channel is changed at the request of the viewer. The communication service can be provided through the changed frequency.

That is, the allocator 130 may transmit the information on the service provision start time when the frequency channel is allocated to the viewer.

At this time, the service provision start time may correspond to a reference time in a cell of a frequency band to which the viewer belongs.

In this case, the reference time must be synchronized with the time of the broadcast service providing apparatus 100, and the time delay according to the distance of the subscriber must be considered.

That is, the assigning unit 130 should have the same reference time to inform the terminal apparatus 10 of the viewer of the serviceable time.

At this time, the allocation unit 130 can provide the broadcasting service after transmitting the serviceable time to the viewer.

At this time, the confirmation unit 120 can receive a broadcast service of a second broadcast channel that is an idle frequency from the viewer while the broadcast service is being provided to the viewer on the first broadcast channel.

In this case, the assigning unit 130 may cancel the assignment of the viewer of the first broadcast channel and allocate the viewer to the second broadcast channel to provide the viewer with the broadcast service of the second broadcast channel.

In this case, if the allocation unit 130 is providing the communication service such as the subscriber uplink data transmission through the first broadcast channel, the allocation unit 130 transmits a message for ending the communication service provision through the first broadcast channel to the terminal apparatus (10).

At this time, the allocator 130 can continuously provide the communication service by allocating the viewer to the second broadcast channel that can provide the broadcast service requested from the viewer.

Table 2 is a table showing a service time message and a new service channel assignment message according to an embodiment of the present invention.

Referring to Table 2, a service start time message (TAGN message) can inform the subscriber of the service start time.

At this time, the service start time message (TAGN message) may include a subscriber identifier (Subscriber_ID) and a service time (Current_service_time).

The new service channel assignment message (TNAN message) may include a subscriber identifier (Subscriber_ID), a new serviceable channel identifier (Assign_CH_ID), and a service time (New_service_time) on a newly allocated channel.

At this time, the new service available channel in Table 2 may correspond to the channel providing the communication service with the idle frequency channel.

The terminal device 10 of the viewer must suddenly change the frequency channel being used for the communication service. Therefore, instead of the frequency for providing the existing communication service, the new terminal receives the new frequency channel from the broadcasting service providing device 100, Time information for starting the communication service through the frequency channel can be received together.

In addition, if the broadcast channel is no longer available to the current broadcast channel in response to a viewer's viewing request, the allocator 130 may allocate another idle frequency channel to the viewer to provide the broadcast service.

3 is a diagram illustrating a frequency channel distribution according to an embodiment of the present invention.

Referring to FIG. 3, a frequency channel distribution according to an embodiment of the present invention may include frequency bands of a, b, c, d e, and f bands. 4 is a diagram illustrating a modified frequency channel distribution according to an embodiment of the present invention.

At this time, the a and e frequencies know that three viewers in the cell are viewing the channel (the viewer count value can be three).

At this time, the c-frequency can know that two viewers in the cell are viewing the channel (the viewer count value can be 2).

At this time, the d and f frequencies can know that one viewer views the channel in the cell (the viewer count value can be 1).

At this time, it can be seen that the b-frequency is an idle frequency in which no viewer is using the frequency band in the cell (the viewer count value can be zero).

Accordingly, when there is a request from the viewer, the broadcast service providing apparatus 100 can identify an idle frequency that no viewer is currently using, and can assign the b-frequency that is the idle frequency to the viewer.

Referring to FIG. 4, it can be seen that the viewer assigned to the frequency channel shown in FIG. 3 is changed according to the viewer allocation method according to an embodiment of the present invention. That is, in FIG. 3, it can be seen that the allocation of two viewers allocated to the c-frequency is canceled and two viewers are allocated at the b-frequency.

Thus, in FIG. 4, it can be seen that the frequencies c and d are idle frequencies for which no viewer is using the frequency band in the cell (the viewer count value can be zero).

In addition, in FIG. 3, it can be seen that the allocation of one viewer assigned to the frequency d is canceled, and one more viewer is allocated at the frequency f.

5 is a sequence diagram illustrating a frequency allocation process of a broadcast service providing method according to an embodiment of the present invention.

Referring to FIG. 5, in a frequency allocation process of a broadcast service providing method according to an embodiment of the present invention, a terminal apparatus 10 of a viewer can request a broadcast service to a broadcast service providing apparatus 100 (S11).

At this time, the broadcast service providing apparatus 10 can confirm a broadcast channel which is an idle frequency of the broadcast channel frequencies according to a broadcast service request of the terminal device 10 (S12).

In addition, the broadcast service providing apparatus 10 can assign a viewer to a broadcast channel having an idle frequency and provide a broadcast service of the broadcast channel (S13)

6 is a flowchart illustrating a frequency allocation process of a broadcast service providing method according to an embodiment of the present invention. FIG. 7 is a flowchart illustrating an example of the frequency idle confirmation step shown in FIG. 6 in detail.

Referring to FIG. 6, a broadcast service providing method according to an embodiment of the present invention may receive a service provision request (S210).

That is, in step S210, the broadcast service providing apparatus 100 may be requested to provide a service from the terminal device 10 of the viewer.

At this time, in step S210, the CM version of the subscriber from the server or the database managing the subscriber information using the subscriber identifier of the broadcasting service request message received from the terminal device 10 of the viewer, the distance from the current position to the viewer Can be confirmed.

For example, if the broadcast service providing apparatus 100 displays the reference time for providing the service, the step S210 may reflect the error according to the distance to the viewer's terminal device 10.

In addition, the broadcasting service providing method according to an embodiment of the present invention can check whether a viewer is viewing an existing channel (S220).

That is, in step S220, it is checked whether the viewer is new, and if the viewer is an existing viewer, the user can request to cancel the allocation of the broadcasting channel viewed by the existing viewer.

At this time, in step S220, a current viewing channel identifier (current_ch_ID) that can identify the current viewing channel is required to check whether there is a broadcasting channel that the viewer requesting the service currently has. At this time, if the current viewing channel identifier does not have a current viewing channel, the user can input 000 value.

At this time, the identifier (request_ch_ID) of the channel requested by the subscriber may correspond to the identifier of the channel to be viewed.

At this time, the step S220 can confirm whether the channel to be viewed is a channel in which an existing service is provided or a new channel.

At this time, in step S220, the viewer count value of the existing broadcast channel is checked. If the viewer count value is not 0, it can be confirmed that the broadcasting service is being provided to the existing viewer, and the viewer count value CNT ) Can be reduced.

For example, in step S220, the viewer count value CNT may be decreased by one when the existing viewer is unallocated.

At this time, the viewer count value CNT may correspond to the viewer selected channel count value CNT.

At this time, the viewer count value (CNT) of each pre-allocated broadcasting channel managed by the DB server or the internal DB can be checked in step S220.

In addition, in the method of providing a broadcast service according to an embodiment of the present invention, frequency idleness can be confirmed (S230).

Referring to FIG. 7, in operation S230, it is determined whether a channel is available or not in operation S231.

That is, step S231 may determine whether the broadcast channel of the viewer requested by the viewer is idle.

At this time, in step S231, the viewer count value of the broadcast channel is checked, and when the viewer count value is 0, the frequency of the broadcast channel can be confirmed as the idle frequency.

If the viewer count value (CNT) is 0, the corresponding channel is an idle frequency for which no service is provided, so that the corresponding broadcasting channel can provide communication service.

At this time, if the frequency of the broadcast channel is not an idle frequency, it can be checked whether the idle channel service is available (S232). If the frequency of the broadcast channel is idle, a viewer is assigned to the broadcast channel (S234)

At this time, in step S232, if the frequency of the broadcast channel is not the idle frequency and the service of the broadcast channel is the idle channel service, the idle channel service can be terminated (S233).

At this time, if the service of the broadcast channel is not an idle channel service, a step S232 may allocate a viewer to the broadcast channel (S234).

At this time, the idle channel service may correspond to the communication service being provided in addition to the broadcasting service at the frequency requested by the viewer.

At this time, the step S234 may increase the viewer count value (CNT) in the broadcast channel

For example, the step S234 may increase the viewer count value CNT by 1 when allocating a new viewer.

In addition, the broadcasting service providing method according to an embodiment of the present invention can perform frequency allocation (S240)

That is, step S240 may increase the viewer count value (CNT) of the channel to be watched and then perform channel assignment (assign_ch) to the viewer.

At this time, the step S240 can provide the viewer with the broadcast service provided by the broadcast channel of the allocated frequency.

FIG. 8 is a sequence diagram illustrating a service time allocation and a frequency allocation process of a broadcast service providing method according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 8, in the service time allocation and frequency allocation process of the broadcast service providing method according to an embodiment of the present invention, the broadcast service providing apparatus 100 can allocate the service time to the terminal device 10 of the viewer (21).

At this time, the terminal device 10 may request the broadcast service providing apparatus 100 for a broadcast service different from the previously provided broadcast service, referring to the service time (S22).

At this time, the broadcast service providing apparatus 100 may terminate the existing service provided by the viewer (S23).

At this time, the broadcast service providing apparatus 100 can check the idle frequency of the requested other broadcast service and allocate the viewer to the broadcast channel which is an idle frequency (S24).

9 is a flowchart illustrating a service time and frequency allocation process of a broadcast service providing method according to an embodiment of the present invention.

A method of providing a broadcast service according to an embodiment of the present invention may first allocate a service time (S310).

That is, the step S310 may provide the broadcast service time to the viewer.

In this case, in order to provide a communication service such as uploading of upward data of the viewer through the broadcast channel of the idle frequency, the step S310 may notify the viewer of the time available for providing the service.

In this case, in step S310, the idle frequency channel is changed at the request of the viewer by informing the viewer of the time available for providing the service. The communication service can be provided through the changed frequency.

At this time, the step S310 may transmit the information on the service provision start time when the frequency channel is allocated to the viewer.

At this time, the service provision start time may correspond to a reference time in a cell of a frequency band to which the viewer belongs.

In this case, the reference time must be synchronized with the time of the broadcast service providing apparatus 100 of the viewer's terminal device 10, and the time delay according to the distance to the terminal device 10 of the viewer must be considered .

At this time, the step S310 can notify the terminal device 10 of the viewer of the serviceable time which is the same reference time.

In addition, in the method of providing a broadcast service according to an embodiment of the present invention, a broadcast service request of a viewer can be confirmed (S320).

At this time, the viewer can request a broadcasting service for the idle frequency channel, which is the second broadcasting channel providing the broadcasting service, while the broadcasting service is being provided to the viewer on the first broadcasting channel in step S320.

In this case, if the broadcast service request is not received in step S320, the time of another broadcast service can be provided to the viewer in step S310, and if the broadcast service request is received, the existing service can be terminated in step S330.

Also, the broadcasting service providing method according to an embodiment of the present invention can terminate the existing service (S330).

That is, the step S330 may terminate the allocation of the viewer of the first broadcast channel providing the existing broadcast service and terminate the broadcast service of the first broadcast channel.

At this time, if the communication service such as subscriber uplink data transmission is being provided through the first broadcasting channel, a message to terminate the communication service provision through the first broadcasting channel is transmitted to the terminal device 10 ).

In addition, the broadcasting service providing method according to an embodiment of the present invention can allocate a frequency (S340).

That is, in step S340, the second broadcasting channel providing the broadcasting service requested by the viewer is checked for idle frequency, and the viewer can be allocated.

At this time, the step S340 may allocate a viewer to the second broadcast channel and provide a communication service.
