There is a parser 620, section filter 622, Non-Volatile Memory (NVM) manager 624, and a graphics engine 624 for outputting a screen is provided. There may be. The network protocols include Dynamic Host Configuration Protocol (DHCP) 626, Network Address Translator (NAT) 628, User Datagram Protocol (UDP) 630, Transmission Control Protocol (TCP) 632, and Real-time Streaming (RTSP). Protocol (634), Internet Protocol (IP) (636), Internet Control Message Protocol (ICMP) (638), Address Resolution Protocol (ARP) (640), Point-to-Point Protocol over Ethernet (PPPoE) / Point (PPPoA) -to-Point Protocol over ATM) / bridge 642, and the like. Here, the browser 602 includes not only a browser for outputting the web screen through the monitor but also a T-browser (Television-borswer) for outputting the web screen through the HDTV 212.

In addition, the device abstraction layer (DAL) 644 is a hardware abstraction layer (HAL) used in order not to affect the upper software even if the devices are changed, and corresponding devices in the lower driver 646, that is, the hardware 648, respectively. It is connected with the drivers to drive the. The driver 646 includes a WLAN driver for the WLAN interface unit 204, an Ethernet driver for the Ethernet interface unit 244, an HPNA driver for the HPNA interface unit 206, and an IEEE 1394 for the IEEE 1394 interface unit 210. Driver, MPEG decoder driver for MPEG-2 decoder 236, PLC driver for PLC controller 208, remote control driver for IR receiver 248, ATM driver for ATM processing of MPU 228, UTOPIA interface unit UTOPIA driver for 250, VDSL driver for VDSL processing unit 252, PCI driver for system bus 230, USB driver for serial interface unit 242, and the like.

As described above, the DAL 644 has upper application software 650 corresponding to various application software shown in FIG. 5 and lower drivers, WLAN 652, Ethernet 654, ..., PCI 656, USB ( Referring to FIG. 6, which shows the connection with 658, the interface operation of the DAL 644 is described as follows. The interface of the DAL 644 to devices registers a new device, initializes ports and channels for that registered device, receives packets from the application software 650, and sends packets to or from the device. The incoming packet is sent to the application software 650. At this time, the packet received by the DAL 644 may include a device creation message Device create, a data packet channel rx packet, and the packet sent to the devices may include port and channel initialization message Port & channel init, APIs call message, APIs call, and the like. There may be. The interface of the DAL 644 to the application software 650 registers ports and channels when the devices request registration, sends user data to the devices and sends data received from the devices to the application software 650, You can cancel data transmission and reception in progress and send or request attribute values. In this case, the command that the application software 650 sends to the DAL 644 may include open, close, set attribute, get attribute, connect, cancel data, send data, and receive data.

For example, to use an Ethernet device, register the Ethernet device as eth0, initialize the port and channel for the registered Ethernet device with ID = eth0, and assign the port and channel 1 and 10 respectively. You can also have multiple channels on one port. For example, if you add a new channel to the port of ID = eth0 assigned above, you get:

eth0: port = 1, channel = 11

eth0: port = 1, channel = 12

In order to receive data using the Ethernet device in the application software 650, a connection command connect is sent to the DAL 644 using the port = 1 and the channel = 10, and when the connection is completed, the data is received by the receive command receive. It also works in the same way to send and receive data through multiple devices at the same time.

For example, in order to simultaneously watch HDTV or VOD and use the Internet through the VDSL 120, each device is registered as follows.

Decoder device: ID = HDTV_DECODER, port = 3, channel = 30

VDSL device: ID = VDSL, port = 4, channel = 40 --- for HDTV

ID = VDSL, port = 4, channel = 41 --- for internet

If the user of the integrated terminal 200 wants to watch the HDTV broadcast through the HDTV 212, the remote controller 246 may select a channel or control the volume. When the user requests to watch HDTV broadcasting through the application software 650, the VDSL device is registered with ID = VDSL and port = 4 and channel = 40 are registered first. Also register the decoder device with ID = HDTV_DECODER and register port = 3 and channel = 30. If the Internet is used in this state, one channel is added to an existing VDSL port at the request of the application software 650. That is, channel = 41 is added to port = 4 of ID = VDSL.

Meanwhile, the MPEG TS of the HDTV broadcast transmitted from the HDTV broadcast encoding apparatus 108 of FIG. 1 is received through the VDSL interface unit 202 of FIG. 2 via the access network 102 and the VDSL 120, and the VDSL interface. The MPEG TS related ATM cell according to the HDTV broadcast output from the unit 202 is converted into MPEG TS by the MPEG-TS unit 234 and output to the MPEG-2 decoder 236. The MPEG-2 decoder 236 detects the video ID and the audio ID corresponding to the channel selected by the user using the remote controller 246, decodes the MPEG TS from the TS, and outputs the HDTV encoder 238 to the HDTV encoder 238. The HDTV signal is sent to the HDTV 212. Accordingly, the user can watch the HDTV broadcast received through the VDSL 120 from the service providing system 100 through the access network 102 through the HDTV 212.

As shown in FIG. 7, a software operation structure for receiving HDTV broadcasts is shown. Among the modules in the dashed block in FIG. 7, that is, the modules shown in FIG. 5, the navigation APIs 618, the PSI / PSIP parser 620, the section filter 622, and the NVM manager 624 are provided for viewing HDTV broadcasts. The control modules are software modules corresponding to the MPEG-2 decoder 236. The navigation APIs 618 respond to requests from application software 650 that handles input of the corresponding keyboard or mouse or remote control 246 when the user selects the desired channel using the keyboard or mouse or remote control 246. Request tuning to the tuner / VDSL processing unit 666 for the selected channel and send the database creation start message Start Database Building to the PSI / PSIP parser 620 for parsing MPEG MPEG. It operates the audio / video DAL APIs 660 to view audio and video when the final parsing is finished, and stores various information for watching HDTV broadcasts through demultiplexing DAL APIs 662 or NVM manager 624. Or read from. Here, the tuner / VDSL processing unit 666 refers to a tuner or VDSL processing unit 252 of the HDTV 212. When the tuner is operated, the tuner / VDSL processing unit 666 corresponds to a case where an HDTV broadcast is received through a terrestrial wave or a cable. ) Corresponds to a case where HDTV broadcast is received through the VDSL 120. The tuner / VDSL processor 666 notifies the navigation APIs 618 of the tuning result of the channel according to the tuning request.

The PSI / PSIP parser 620 receives a parsing request message, that is, a database creation start message Start Database Building, from the navigation APIs 618 and may be referred to as an HDTV engine. The PSI / PSIP parser 620 receives a section status by requesting a section with the section filter 622 and receives section status from the MPEG TS, such as audio, video, EPG information, closed caption data, and the like. The master guide table (MGT), terrestrial virtual channel table (TVCT), program association table (PAT), program map table (PMT), and system time table (STT) are collected from the PSIP table.

In addition, the section filter 622 waits for a message from the application software 650 and then the application software 650 requests the packet identifier (PID), table ID, table version number, and section number via the navigation APIs 618. When a request is made to obtain information such as SPI / PSIP, the demultiplexed DAL APIs 662 sends a section status of the demultiplexed data from MPEG TS to the PSI / PSIP parser 620. Parser 620 obtains the necessary information.

The NVM manager 624 reads or writes data from the NVM in the memory 232 through the NVM DAL APIs 664. The data written to or read from the memory 232 is parsed into a table structure, current information, Various channel information can be stored.

Also, the audio / video DAL APIs 660, the demultiplexed DAL APIs 662, the NVM DAL APIs 664, etc. are APIs included in the DAL 644 described above, and the audio / video DAL APIs 660 are HDTVs 212. APIs for audio / video processing and output, demultiplexing DAL APIs 662 are APIs for MPEG TS demultiplexing of MPEG-2 decoder 236, and NVM DAL APIs 664 are in memory 232. APIs for NVM.

Meanwhile, the PSI / PSIP parser 620 has a system information task and an event information task. First, as shown in the state transition diagram of FIG. 8, the system information task has three operation modes, namely, an idle state S1, an active state S2, and a monitor state S3. Waits for a message from the application software 650, and when the message comes in, it starts preparing to put the contents into the database in the active state (S2) and starts collecting the desired table. At this time, the application software 650 may receive one of three messages, that is, a message for retrieving PSI / PSIP information, a channel change message, a VCT (Virtual Channel Table), or a message for changing the STT version. When the table is created, the state changes to the monitor state (S3) .In the monitor state (S3), the TVCT of the received MPEG TS checks whether the version is the same as the received table. If it's the wrong version, you can start building the table again by sending a message to the event information task. In addition, when the channel is changed from the idle state (S1), the state immediately transitions to the monitor state (S3) to start the database creation during the channel hop (channel hop), and when the database creation is finished, the transition to the idle state (S1). When an event such as stopping HDTV reception occurs while in the active state S2, the database is stopped and transitioned to the idle state S1.

9A and 9B are flowcharts illustrating the system information task of the PSI / PSIP parser 620 described above, and FIG. 9A shows the flowcharts of the active state S2 in steps 700 through 724, and FIG. 9B. Shows the process flow of the monitor state S3 in steps 726 to 734. When the system information task receives a parsing request message from the navigation APIs 618 in the idle state S1, the system information task becomes the active state S2. First, the TVCT is performed by the section filter 622 in step 700 of FIG. 9A. A section request is made and the acknowledgment Ack is waited from the section filter 622 until a predetermined time-out is made in steps 702 to 704.

If the positive response Ack comes before the timeout in steps 702 to 704, the TVCT is parsed in step 706, and then MGT section request is made to the section filter 622 again in step 708. In step 710, the MGT is parsed. Here, TVCT includes major channel number major num., Minor channel number minor num., Short channel name short name, carrier frequency carrier freq., Channel TS ID, program number. (program number) progr. num., access control flag flags, location field for extended text messages descriptors, service type service type, and the like. Table 1 shows an example after the parsing for TVCT.

The MGT also includes the table type table_type, PID, and version number version num. Table size may be included. Table 2 shows an example after the parsing for TVCT.

If the acknowledgment Ack for the TVCT does not come until the timeout is reached in steps 702 to 704, it means that there is no TVCT in the stream. Therefore, only PAT and PMT are parsed. Similar to TVCT parsing, in order to parse the PAT, the PAT section request is made to the section filter 622 in step 712 to receive the positive response Ack, and then the PAT parsing is performed in step 714, and the section filter 622 in step 716. In step 718, the PMT section is requested to receive a positive response Ack. After parsing the PAT and PMT, a physical channel number is assigned in step 720 to decode audio and video of MPEG TS. In this case, since the virtual channel does not exist, only the physical channel can be decoded.

The PAT has a PID value of 0 and a PMT address each time a stream enters. PMT also has a physical channel number for actually showing audio and video. An example of the contents of a stream having four PMTs as PAT PAT (PID 0000) = 0100, 0200, 0300, and 0400 is as follows.

PMT 1 (PID 0100) = Video PID 0101, Audio PID 0102, Audio PID 0103, PCR 01FF

PMT 2 (PID 0200) = Video PID 0201, Audio PID 0202, PCR 01FF

PMT 3 (PID 0300) = Video PID 0301, Audio PID 0302, PCR 02FF

PMT 4 (PID 0400) = Video PID 0401, Audio PID 0402, PCR 0401

After the parsing of steps 706 to 710 or 712 to 720 is completed as described above, the database is updated in step 722, and then flash memory in the memory 232 if necessary. Even light. Thereafter, the process transitions to the monitor state S3 in step 724.

When the monitor state S3 is reached, the system information task parses only the MGT of the MPEG TS received in steps 726 to 728 of FIG. 9B, and the EIT (Event Information Table) in the MGT in steps 730 to 732. , The version of the event time table (ETT), the rating region table (RTT), etc. is compared with the version of the EIT, ETT, RRT, etc., which are received in advance. If it is the same, since the version has not been changed, the process is repeated from step 726 to continue to the monitor state (S3). If the version is changed, the table collection message is sent to the event information task in step 734 to change the version. To the event information task.

The event information task has two states, an active state and an idle state. In the idle state, the device transitions to the active state at the request of the navigation APIs 618 or the PSI / PSIP parser 620. Referring to FIG. 10, which shows a process flow diagram of such an event information task as steps 800-818, first, requests from the navigation APIs 618 or the PSI / PSIP parser 620 are performed in steps 800-802. By checking the type of table, the desired table is parsed according to the type of table requested. If an EIT is requested, an EIT section request is made to the section filter 622 at steps 804 to 806, and when the positive response Ack is received from the section filter 622, the EIT is parsed. Length, title, and so on. Similarly to the EIT, the ETT and the RRT are parsed in steps 808 to 810 or in steps 812 to 814. The ETT can contain details that the EIT can't express, including who the characters are and what they are, and the RRT shows where the stream will be broadcasted, who is the broadcaster, and what are the available ratings. It includes. After performing steps 804 to 806 or steps 808 to 810 or steps 812 to 814, it is determined whether there is another table to be parsed in step 816. The process is performed again from step 800, and if there is no table to be parsed, the process transitions to the idle state at step 818. Once parsing is complete, the database can be updated and, if necessary, updated in flash memory as well.

After the parsing is completed by the PSI / PSIP parser 620 as described above, the user can watch the HDTV broadcast by decoding the audio and video.

On the other hand, the user selects the desired VOD content by using the remote control 246, the keyboard or the mouse on the web screen provided through the HDTV 212 to receive HDTV-level VOD content from the VOD server 110, or the Ethernet interface unit 244 The VOD server 110 selects the desired VOD content by accessing the VOD server 110 through the Internet 106 by a PC connected to the PC, a PC connected to the WLAN, a PC connected to the WLAN, or the like. The MPEG TS of the content is transmitted to the integrated terminal device 200. Receiving the MPEG TS of the VOD content so that the user can view it is almost the same as the above-described HDTV broadcast reception. One other part is to receive the VOD content, the desired data from the VOD server 110 is carried in the IP packet, and the integrated terminal device 200 receives the VOD data from the IP packet using the VDSL 120 and extracts the VOD data in the IP packet. These are just different. The VOD data may have various forms. For example, the MPEG-2 TS type of service may be configured as shown in FIG. 11 for a high quality VOD service. The packet structure of FIG. 11 is composed of feeds such as Media Access Control (MAC), Internet Protocol (IP), Transmission Control Protocol (TCP), Internet data, and Frame Check Sequence (FCS) for real-time transmission of VOD data. Unlike the general Internet packet structure, an example of the configuration of the MAC, IP, User Datagram Protocol (UDP), Real-time Streaming Protocol (RTSP), MPEG-2 TS, FCS and the like. VOD data is carried in an MPEG-2 TS feed. In the VOD server 110, VOD data is encapsulated and transmitted in MPEG2-TS using the RTSP protocol in the Ethernet packet, and encapsulated and parsed in the integrated terminal device 200 so that the user The HDTV 212 allows viewing of VOD content.

Meanwhile, the Internet 106 may be accessed from a PC connected to the Ethernet interface unit 244 of the integrated terminal 200, a PC connected to a WLAN, a PC connected to an HPNA, and the like. To this end, the MPU 228 selects one of several modes, such as Internet Protocol (IPoA) over Asynchronous Transfer Mode (IPoA), bridge mode, and the like, of Point-to-Point Protocol over Ethernet (PPPoE). After converting an IP packet into an ATM cell, it is transmitted through the VDSL 120 through the VDSL interface unit 202 and input through the access network 102 to the RAS 112, where the ATM is terminated and converted back into an IP packet. Since it is connected to 106, the Internet 106 can be accessed.

As described above, the software operation structure for accessing the Internet has a structure in which the navigation APIs 618 are linked to the Internet 106 in FIG. 7 described above. When a user enters a channel number using the remote control 246 to watch a TV broadcast, a scan request is sent from the application software 650 according to the remote control 246 to the navigation APIs 618 and the navigation APIs 618. The tuner operates the tuner during the tuner / VDSL processing unit 666. In this state, when the user presses a specific key on the remote controller 246, the menu screen is displayed as an OSD (On Screen Display) screen through the HDTV 212 in which the TV broadcast is output. When the user selects one of a desired service, for example, the Internet, a VOD, or a PLC, a task required by the navigation APIs 618 is operated. If the Internet is selected, the Internet task is executed by the navigation APIs 618, the TV broadcast is stopped and the browser 602 is operated. From this point on, the user may use the Internet 106. In this case, the user interface may be used by using a device such as a wireless keyboard or a wireless mouse. Not only that, but it can also be configured to use a TV and the Internet at the same time by composing a screen like a picture in picture (PIP). In other words, the broadcast screen is displayed on the entire screen, and the Internet screen is displayed as desired by using the OSD. At this time, the broadcast continues to run in the block indicated by the dotted line in FIG. 12, and at the same time, the browser 602 runs to access the Internet. When watching the HDTV broadcast and accessing the Internet at the same time, the MPU 228 selects one of PPPoE modes and converts the IP packet into an ATM cell. The VPI and VCI values used here are used in the HDTV broadcast. Since it is different from the value of the collision, no collision occurs.

On the other hand, the control of the home appliances 222 installed in the subscriber premises 104 is operated as in the case of the above-described Internet access. When the user selects the PLC among the functions in the menu using the remote control 246, the web browser is started and connected to a specific URL (Uniform Resource Locator), the integrated terminal device in the subscriber premises 104 on the HDTV 212 screen If the home appliance 222 connected to the display 200 is displayed, and the home appliance 222 is selected by the remote controller 246 that the user wants to control, the home appliance may be controlled.

An example of such a home appliance control will be described below. For example, when gas is detected by a gas sensor connected to a PLC controller, the gas detector sends the signal to the power line 220 through the PLC controller, and the MPU 228 in the integrated terminal 200 receiving the signal receives the TCP / IP. The packet is connected to the Internet 106 through the VDSL 120 to inform a WAP (Wireless Application Protocol) server (not shown). The WAP server then sends a short message service (SMS) message to the mobile phone to inform the user that the gas has been leaked. In general, the user can access the PLC server running the WAP server through the mobile phone and check the gas valve status. If the gas valve is open, the gas valve can be locked through the WAP server. In this case, when the WAP server sends a command to close the gas valve using the TCP / IP packet to the integrated terminal device 200, the MPU 228 of the integrated terminal device 200 by the PLC controller 208 to the power line 220 Send the appropriate command via).

As described above, the multimedia service, the Internet access, the home appliance control, and the like are possible with only one integrated terminal device 200 and the remote controller 246 is convenient. By doing so, we can network the whole country so that we can watch HDTV broadcasts not only at home but also at hospitals, hotels, businesses, broadcasters, etc., so that we can eliminate the blind spot, enjoy cultural life at low cost, and use various multimedia services such as HD VOD service. do. In addition, since only one VDSL 120 line is introduced into the subscriber premises 104, the convenience of installation is increased, the cost is reduced, and the fee for watching HDTV broadcasting, VOD service, Internet access, etc. can be integrated. do. In addition, by connecting the subscriber premises 104 to the network by one integrated terminal device 200, various subscriber premises 104 services can be provided and operation management becomes easy.

Meanwhile, although FIG. 1 illustrates an example of using an ATM-PON as an access network 102, an IP packet may be directly transmitted between the service providing system 100 and the integrated terminal device 200 instead of an ATM cell. have. Accordingly, in the service providing system 126 of the integrated home network system of FIG. 13, a gateway 128 for accessing the Internet 106 is used instead of the RAS 112, and an access network 122 is used instead of an ATM switch 114. IP switch 124 is used. In addition, unlike the integrated terminal device 200, in the integrated terminal device 258 configured as shown in FIG. 14, as shown in FIG. 14, the UTOPIA interface unit in the VDSL interface unit 260 corresponding to the VDSL interface unit 202 of FIG. ATM cell conversion is also performed in the VDSL processing unit 262 corresponding to the VDSL processing unit 252, the MPEG-TS unit 266 corresponding to the MPEG-TS unit 234, the MPU 228, and the like, without using the 250. It is not necessary. The IP packet may be transferred between the MPU 228, the VDSL processing unit 262, and the MPEG-TS unit 266 via the Ethernet 264 as it is.

On the other hand, the integrated home network system according to the present invention described above can be applied as a system for providing various additional services through a network in a lodging place such as a hotel. Such an additional service system can provide not only the above-described HDTV digital broadcasting service, high-speed Internet service, VOD service and various equipment control services in the room using PLC, but also additional services such as guide service, interworking service, individual service, and paid service. do. The guide service refers to a service that provides basic guide information such as hotel introduction, hotel service type and price information guide (accommodation fee, room bar use, laundry, etc.), surrounding information guide, and broadcast guide. The interworking service refers to a service that provides information on news, weather, stocks, etc. in conjunction with an external server such as news, weather, stocks, and the like. Individual service refers to services such as e-mail transmission, schedule management, usage fee inquiry, and checkout. Paid service means services such as karaoke, games, room service application.

Hereinafter, an embodiment to which the present invention is applied as such a network supplementary service system will be described in detail.

FIG. 15 is a diagram illustrating a system configuration for the additional service as described above using the integrated home network system of FIG. 1 described above in a hotel such as a hotel, and the like to provide additional services requested through the web to the customers. Web server 130, room management server 132, authentication server 134, billing server 136, karaoke server 138, game server 140, mail server 142 It is installed in a property and connected to the Internet 106, and the web server 130 is connected to an external server such as a news server 144, a stock server 146, and a weather server 148 via the Internet 106. Connected. The integrated terminal device 200 is installed in a guest room, provides each customer with Internet access through the subscriber line 120, and receives an HDTV broadcast or VOD content through the subscriber line 120 and installs in the guest room. In addition to providing the service information to the 212, the HD server 212 provides the additional service requested by the customer by accessing the web server 130 according to various additional service requests of the customer. In FIG. 15, the same reference numerals are given to the same elements as in FIG. 1.

The customer, ie, the user, may receive various additional services as described above through the HDTV 212 shown in FIG. 1 and the remote controller 246 of FIG. 2 described above. As described above, the user interface is displayed on the HDTV 212 screen through a web browser mounted on the integrated terminal 200, that is, the browser 602. In addition, all web content to be shown to the user is stored in the web server 130. In addition, the web server 130 is pre-stored HTML (Hyper Text Markup Language) pages for the guide service corresponding to the Uniform Resource Locator (URL) for each guide service item.

Among the additional services as described above, the guide service is provided between the integrated terminal device 200 in the cabin, the HDTV 212, and the web server 130 corresponding to the server side. 16 is a flowchart illustrating a process of the integrated terminal device 200 for providing such a guide service, in steps 700 and 712, and a flowchart of a web server 130 is shown in steps 800 and 806. Refer to 17 to provide guidance services to customers. First, the MPU 228 of the integrated terminal device 200 outputs a main screen for providing an additional service by the web to the HDTV 212 by operating a web browser in step 700, and remote controller 246 from a user in a room. Wait for input In this case, the main screen provides a screen through which the user can select service items of the above-described guide service, interworking service, individual service, and paid service. Then, the user in the room sees the main screen shown on the web screen of the HDTV 212, and selects a specific service, for example, a broadcast guide, to be serviced from the guide service item by using the remote controller 246. Then, in step 702, the integrated terminal device 200 transmits a Hyper Text Transfer Protocol (HTTP) request message informing the corresponding service request to the web server 130 in response to the web server 130. Wait 130 for an HTTP response message corresponding to the service result. In this case, if the user selects a service other than the guide service, the process proceeds from step 702 to step 704 to process the service.

As described above, when the web server 130 receives the HTTP request message for requesting the guidance service from the integrated terminal device 200, the web server 130 responds to the response in steps 800 and 802 in step 806. In the step, the HTML page corresponding to the URL of the specific service among the guide service items stored in the web server 130 is read and transmitted to the integrated terminal device 200 as an HTTP response message. At this time, if the HTTP request message received from the integrated terminal device 200 is a message for requesting a service other than the guide service, the process proceeds from steps 800 to 802 to 804 to process the corresponding service.
