In general, since the late 1990s, digital satellite broadcasting, digital cable TV, and digital terrestrial TV have been in full swing, and TV electronic commerce that provides Internet TV functions in TV media has emerged.

As TVs have emerged as a powerful internet access means, TV e-commerce (TV based e-commerce) means television e-commerce using the convenience of TV and the immediacy of the Internet.

From the point of view of viewers, TV home shopping, like Internet e-commerce, does not go to the store directly to purchase goods, but instead orders and delivers them from TV-mall's store (TV-Shop), saving time, space and labor. Can be.

Currently, there are various analog TV standards such as NTSC, PAL, SECAM, etc. used by the US and Korea, and only one-way services are provided from program providers (PP) such as YTN, SBS, and KBS.

Currently, digital data broadcasting is still in its infancy, and the data broadcasting service standards for terrestrial broadcasting include the US Advanced Television Systems Committee-Digital TV Application Software Environment (ATSC-DASE) and Advanced TV Enhanced Forum (ATVEF). It proposes the use of HTML / xHTML, and DASE-2 was confirmed following DASE-1, and there are European DVB-MHP (Digital Video Broadcasting-Multimedia Home Platform) method and other US OCAP and JavaTV.

The standard of data broadcasting is in line with the standard method of digital broadcasting in that it is developing two axes of the United States and Europe, and the global standardization trend is the standard of ATSC-DASE of USA and DVB-MHP of Europe which provides interactive services. Is being adopted.

ATSC is the next-generation TV committee in the United States, established to develop a broadcast standard for analog-to-digital broadcasting. The ATSC standard adopts MPEG-2 Main Profile as video signal and Dolby AC-3 as audio signal. Signal multiplexing follows the transport layer defined by MPEG-2, and ATSC has a total of 18 video formats and supports all HDTVs.

Data broadcasting service based on DASE (Digital TV Application Software Environment) consists of a combination of an application written in DASE Java API and a declarative application written in HTML.

In Europe, Digital Video Broadcasting (DVB) has been selected as the digital broadcasting standard by the European Telecommunication Standardization Institute (ETSI), and transmission systems for satellite (DVB-S), terrestrial (DVB-T) and cable (DVB-C) channels. In this case, IP (Internet Protocol) content is packetized in MPEG-2 transport stream format and transmitted through this channel.

Since TV e-commerce must use interactive TV because of the nature of services such as home shopping and home banking, interactive TV is currently available.

First, there is a method using Internet TV. Internet TV can provide various additional services such as home shopping, home banking, and distance education as well as basic functions of the Internet such as internet information search and e-mail transmission by installing a set-top box (STB) on an existing TV. have. Set-top box (STB) performs the function of transmitting and receiving information between the Internet and the TV. Second, it uses interactive digital TV with data broadcasting. Data broadcasting provides internet and e-commerce functions as well as broadcasting program-related information and weather information such as weather, news and traffic through the broadcasting network.

In the European market, data bidirectional services are categorized into three groups: weather channels, information-oriented channels such as EPG (Electronic Program Guide), which allows you to display TV program schedules and program searches via remote control, e-commerce including home banking, and online. It consists of entertainment services connected to stock investment channels.

First, there is a form of commerce by connecting to the Internet through a TV, such as using an Internet TV, and another form of purchasing while watching information transmitted through a broadcasting network through data broadcasting together with a broadcast program.

TV e-commerce can be classified into two types: e-commerce through Internet TV and e-commerce through digital TV.

1. E-Commerce via Internet TV

E-commerce through internet TV such as home shopping and home banking has developed the set-top box that can search the Internet through TV, and the internet TV industry is actively promoting TV e-commerce. The most active places in the Internet TV market are the US and Japan, which began service in the mid 90s.

As high-speed Internet services such as ADSL and cable TV networks are recently being distributed to large-scale apartment complexes, the Internet TV business is expected to spread widely. Recently, the set-top box has been developed, which is able to watch over-the-air, cable, satellite, and Internet TV, and also has an interactive TV function.

Foreign companies, including the United States, provide the Internet search and various contents services through set-top boxes or TV-embedded terminals, which is the same as domestic companies, but places much higher weight on interactive contents services for the digital TV era. In addition, different companies are taking charge of the cooperation between the hardware set-top box (STB) and the software content.

In the US, the number of subscribers secured by Microsoft (MS) -operated Web TV is currently 1.3 million, which is incomparably larger than that of Korea, which is now in its infancy. Sony, Philips, Fujitsu, Mitsubishi We are supplying internet TV terminals. Since this year, there are a growing number of companies entering the Internet TV business. AOL, which merged with Time Warner, will launch the AOL TV service, and Hong Kong Star TV will join the C & W HKT, the largest telecommunications company in Hong Kong, to join the Internet TV business. These companies will provide 50 TV channels such as entertainment, news and home shopping, VOD and high-speed Internet services.

2. Electronic Commerce through Digital TV

Satellite data broadcasting was first introduced in the United States and Europe in 1997, and is currently being settled in the market. Terrestrial waves have been experimentally broadcast since 1999 in the United States and the United Kingdom.

BskyB in the UK has been providing e-commerce services via satellite since October 1999 using OpenTV's solution, which uses a set-top box and selects a menu using the remote control.

In the United States, EchoStar and DirecTV dominate the interactive digital TV market via satellite, with more than 11 million subscribers in the United States.

OpenTV is a company that produces solutions that implement interactive digital TV. BskyB in the UK and EchoStar in the US are also adopting OpenTV's solution. The company is recognized by operators of satellite, cable and terrestrial broadcasters worldwide, and has installed its software on more than 7.7 million digital TVs worldwide.

In Korea, we are preparing for the standardization connection between terrestrial and satellite data broadcasting. In the case of terrestrial data broadcasting, TV manufacturers and research institutes participate in most international standardization organizations to develop related technologies. Recently, three domestic consumer electronics companies are adopting three broadcasting standards mainly adopted in Europe and North America, such as DASE (DTV Application Software Environment), ATVEF (Advanced TV Enhanced Forum), and DVB (Digital Video Broadcasting) in Europe. The company is pushing for the development of two-way digital TVs that support the market. Once the phase of two-way digital TVs is established, electronic commerce through TVs will be activated.
