Abstract—Aligned with the rapid change of broadcast environment TV is no longer than a passive device to receive a signal of terrestrial
television broadcasting. A Smart TV is the new trend of integration of the Internet and Web 2.0 features into the modern television sets
and set-top boxes. The users having much experience in a computer want to use a Smart TV alike. However, a Smart TV has yet toprovide various user interface devices such as a mouse and a keyboard thus it is needed to develop new search technology to analyze user
intents from a simple user keyword phrase and search the target contents from the multiple sources including broadcast network andInternet. In this paper, we proposed the framework of semantic analysis based integrated multi-level search system to improve search
accuracy and expand search coverage. The proposed system can retrieve the user desirable multimedia contents from various sources at atime by analyzing an ambiguous user keyword phrase with ontological knowledge.
Keyword— Semantic Network, Multi-Level Search, Integrated Search, Smart TV
