Embodiment
The function of enough information searches can't be provided for the user at existing television set, the present invention proposes a kind of TV program search method based on television image, the user's interest television image is connected external network extensively search for, provide maximized information search service TV user.
Be illustrated in figure 1 as the schematic diagram of realizing search system of the present invention.This search system comprises: several are used for the TV receiving apparatus 10 of received television program, and its outgoing television signal is given the television set 20 that connects; Connect the webserver 30 of several TV receiving apparatus 10 by network, this webserver 30 receives the searching request that TV receiving apparatus 10 send and carries out text search or/and picture searching.Wherein, the TV receiving apparatus 10 preferred IP bi-directional set-top boxes that adopt.
In conjunction with shown in Figure 2, further elaborate specific implementation step of the present invention:
Step S11: the user can utilize remote controller intercepting TV programme current playing frames by the still image function of television set 20.
Step S12: television set 20 provides directionkeys that the user can use a teleswitch and acknowledgement key to come certain part or all image content in the further capturing picture, the picture of intercepting is saved to the memory of TV receiving apparatus 10 with the file (such as * .JPG or * .BMP) of picture format.
Step S13: adopt OCR(Optical Character Recognition, optical character identification by TV receiving apparatus 10) picture that recognition technology identification is preserved extracts the Word message on the picture.
OCR identification mainly is to discern literal or the character on the picture.Such as, the picture of preservation is: Tian An-men, Beijing on the background has caption information " I love Tian An-men, Beijing " below.When then OCR discerns, the Word message that saves as " I love Tian An-men, Beijing " is extracted in the identification of the Word message in picture back, generally adopt text formatting (such as * .txt) access.
