Matrix search of video using closed caption information

摘要

Closed caption data for video programs, such as television programs, may be used to implement a video search. In one implementation, a device may perform a search to obtain video programs that are relevant to the search. The search may be performed using an index generated from closed caption data of video programs. The device may additionally present the video programs that are relevant to the search as a matrix of reduced-in-size images sampled from the video programs that are relevant to the search query. The images may be sampled from the video programs near a position in the video programs corresponding to the positions at which the search query is relevant to the video program.

1. A computing device-implemented method, comprising:
receiving, by the computing device, a search query from a user; performing a search, by the computing device and based on the search query, to identify one or more video programs that are relevant to the search query, where the search is performed using an index generated from closed caption data associated with the video programs; presenting, by the computing device, the video programs that are relevant to the search query as a matrix of reduced-in-size images sampled from the video programs that are relevant to the search query, where the images are sampled from the relevant video programs near a position in the relevant video programs corresponding to the positions at which the search query is relevant to the video programs; detecting selection by the user of one of the video programs that are presented in the matrix of reduced-in-size images; playing, in response to the detected selection, the selected video program, beginning at a location in the selected video program that is a predetermined time period before the position in the selected video program at which the search query is relevant; and where presenting the video programs further includes simultaneously playing each of the presented video programs.
