Apparatus and method for providing real estate information based on digital broadcasting}

The present invention relates to an apparatus and method for providing digital broadcasting based real estate information, and more particularly, to an apparatus and method for providing digital broadcasting based real estate information that enables a user to receive a real estate information service through a digital broadcasting channel.

As is well known, the Transport Protocol Expert Group (TPEG) provides users with digital broadcasting or the Internet, such as Terrestrial Digital Multimedia Broadcasting (T-DMB), Digital Audio Broadcasting (DAB), or Digital Video Broadcasting (DVB). It is a protocol for transmitting information related to transportation and travel.

Currently, TPEG is in parallel with European and international standardization and is responsible for developing standards in the TPEG Forum. The standards proposed to date are TPEG-INV (concept), TPEG-SSF (configuration and semantics, frame structure), TPEG-SNI (service and network information), TPEG-RTM (notice information), TPEG-PTI (public transportation information) ), TPEG-Loc (Location Reference), and many other application services such as CTI (Traffic Congestion Information), PKI (Parking Information), POI (Position Location Information), NWS (News), Weather Information, etc. Are proposed and implemented.

1 is a network configuration diagram of a system for transportation and travel information services. As shown in FIG. 1, a TPEG system includes a contents provider (CP) server 10, a TPEG providing server 20, and a digital broadcasting system 30. , A transparent channel 40 and a user terminal 50.

In the above configuration, the CP server 10 provides the low data to the TPEG providing server 20. The TPEG providing server 20 collects the raw data provided by the CP server 10, processes the raw data according to the TPEG standardized format, and delivers the raw data to the digital broadcasting system 30. The digital broadcasting system 30 transmits TPEG data to the transmission channel 40, that is, DMB, DVB, DAB or the Internet.

Accordingly, the user may be provided with TPEG services such as yugo / news / safe driving / points of interest through various user terminals 50 such as PDAs, PMPs, mobile phones, or set-top boxes.

FIG. 2 illustrates an ISO 7 layer model of the TPEG. As shown in FIG. 2, the TPEG is located in layers 3 to 7, and the physical layer (layer 1) uses a broadcasting network or the Internet.

3 illustrates a DMB / TPEG data transmission protocol and a standardization scheme.

The TPEG protocol, which was developed to provide traffic and travel information in various communication media, particularly in digital broadcasting networks, has a delivery system as shown in FIG. 1. Traffic & Traveler Information (TTI) usually consists of six services: CTI, CTI-SUM (Congestion Information Summary Map), RTM, SDI (Safe Driving Information), POI and NWS. It may be delivered by various transmission media such as FM radio broadcast, Internet, mobile communication network, and the like. However, the information transmitted at this time should be selected and edited in a standardized system as shown in FIG. 3 in order to secure time constraints and accuracy. For this reason, the TPEG providing server 20 performs a task of selecting, editing, and transferring raw data, that is, encoding and transmitting the raw data to a data format conforming to the TPEG standard.

In general, digital broadcasting (digital television broadcasting, digital satellite broadcasting, digital audio broadcasting, etc.) systems provide or plan to provide multimedia data broadcasting services such as TTI, Electronic Program Guide (EPG), and game contents. have. Here, TTI service is a notable field in terms of economic ripple effect and information utilization in the future, and noteworthy reasons include an increase in the number of automobiles and an increase in demand for traffic and travel information due to a five-day workweek. In particular, among the TTI service areas, POI provides high value-added information on POIs such as travel information, cultural information, public facilities, accommodation, medical care, etc., which are needed for drivers, pedestrians, or people who want to visit a specific destination, as well as two-way real estate service. It is expected that this will be possible.

Conventional TTI service technology provides efficient traffic and travel information using various transmission media such as DMB systems and the Internet, which allows new functions or protocols to be modified without interfering with the operation of previous receivers or decoders. It can be widely used in applications requiring efficient information transmission to one-to-many through broadcast system, and one-to-one or multicast application. It is also suitable for use with Internet protocols.

However, the conventional TTI service technology is being standardized on new services such as parking lot information (PKI), congestion and travel time information (CTI), weather information (WEA), and environmental pollution warning (EIA). There was a problem that the service is provided only to traffic information such as defined RTM and PTI.

However, in recent years, in order to overcome the limitations of the existing TPEG's RTM and PTI services, it is possible to provide reservations, purchases, coupons, and evaluation information associated with one-way point of interest information in connection with a wireless communication network such as mobile communication. Service support technologies have been proposed, but are still in the development stage as prototypes. Therefore, there is a need for the development of more various types of high value-added TTI services.
