Abstract
Abstract. Accompanying infrastructure improvements and networking technology innovation, the development of digital home service industry has gotten more and more attention. However, the digital home service levels have not sufficiently met rising demand from users. Therefore, it is urgent to propose and develop new service modes for the digital home. Geographic information services can provide various spatial information services such as map search, spatial information query. It has become an inevitable trend to implement geographic information services in the digital home. This paper proposes three new geographic information services modes for the digital home after sufficient requirement analysis: pushed information service mode, interactive information service mode, personalized information service mode. The key technologies to implement geographic information services on digital televisions are studied, involving digital television middleware technology, network transmission technology and visualization technology. According to the service modes’ characteristics mentioned above, a service system in the digital home is established to implement geographic information services on the basis of digital television. The implementation of geographic information services in the digital home not only enriches the digital home services content, but also promotes geographic information from specialization to public popularity.
Highlights
Accompanying infrastructure improvements and networking technology innovation, the development of digital home service industry has gotten more and more attention (Feng, 2007). , the United States, Britain and other countries have launched various home services which have met the daily needs of the digital home service to a certain extent, such as IPTV services, home security testing services, home care for the elderly, intelligent residential services (Zhang, 2012)

Summary
Accompanying infrastructure improvements and networking technology innovation, the development of digital home service industry has gotten more and more attention (Feng, 2007). , the United States , Britain and other countries have launched various home services which have met the daily needs of the digital home service to a certain extent, such as IPTV services, home security testing services, home care for the elderly , intelligent residential services (Zhang, 2012). Location-relevant information accounts for 80% of the routine life information. It indicates that geographic information services play a significant role in the entire information services. It is essential for people's daily life (Liu, 2004). It is huge potential demand of users that geographic information services penetrate into the digital home and digital television. An in-depth research of design and implementation of geographic information service mode for digital home has been done based on television terminals. We have constructed the geographic information service system for digital home, and make a detailed depiction to system design and key technologies
