Abstract: According to one embodiment, a record information storage module stores record information related to content recorded by an external apparatus in association with a keyword representing the content and user information. A search information storage module stores a search phrase used for searching in an external apparatus in association with user information. A search word handler extracts a predetermined number of words having high search frequency from search phrases stored in association with specific user information to generate a word list. A record information handler extracts keywords stored in association with the specific user information to generate a keyword list. A ranking processor generates ranking information indicating a word in the word list which matches a keyword in the keyword list. A communicator provides the ranking information to an external apparatus corresponding to the specific user information.

Abstract: According to one embodiment, a telop display system includes an extracting module which extracts a telop region identified as an image of a telop from video image information of a television program, an image analyzing module which performs image analysis related to coordinates, a size, and a color scheme of the telop region extracted by the extracting module, a semantic analyzing module which performs text analysis related to a word class and a meaning of the obtained character string, and a classifying module which classifies the telop on the basis of an analysis result of at least one of the image analysis and the text analysis to accumulate character strings of the telops as items of text information classified in units of categories.
