A computer-readable medium storing a sequence of instructions for a program executable by a computer having replay means for replaying video content for carrying out the following steps: accepting one or more keywords from a user; searching a table for a word string including at least one of the accepted keywords, wherein the table includes section information specifying a section part that is a part of video content in which the word string is expressed, the word string, and an identification data specifying a video data for replaying the video content in a manner where the section information, the word string, and an identification data are associated with each other; and performing a control procedure of causing the replay means to replay the section part specified by the identification data and the section information associated with the searched word string, wherein the control procedure includes a procedure of extending a replay time of the section part according to a counted number of the included in text data in the searched word string, wherein the table further includes region information associated with the section information, the word string and the identification data, the region information specifying a partial region which is within a whole region of an image of the video content and in which the word string is expressed, the control procedure includes a procedure to further extend the extended replay time of the section part on the basis of an occupying ratio, which is the size of the partial region, specified by the region information in each section part associated with the searched word string, to the size of the whole image region in each section part, and the control procedure includes a procedure of further extending, when total replay time of section parts is larger than a prescribed threshold value, the extended replay time of each section part according to the length of the total replay time. accepting one or more keywords from a user; searching a table for a word string including at least one of the accepted keywords, wherein the table includes section information specifying a section part that is a part of video content in which the word string is expressed, the word string, and an identification data specifying a video data for replaying the video content in a manner where the section information, the word string, and an identification data are associated with each other; and performing a control procedure of causing the replay means to replay the section part specified by the identification data and the section information associated with the searched word string, wherein the control procedure includes a procedure of extending a replay time of the section part according to a counted number of the included in text data in the searched word string, wherein the table further includes region information associated with the section information, the word string and the identification data, the region information specifying a partial region which is within a whole region of an image of the video content and in which the word string is expressed, the control procedure includes a procedure to further extend the extended replay time of the section part on the basis of an occupying ratio, which is the size of the partial region, specified by the region information in each section part associated with the searched word string, to the size of the whole image region in each section part, and the control procedure includes a procedure of further extending, when total replay time of section parts is larger than a prescribed threshold value, the extended replay time of each section part according to the length of the total replay time.
