<p>The present invention relates to a touch control-based electronic device and a control method thereof. The electronic device includes: a touch detection module which receives a touch input from a user, and generates a touch signal; an indexer which stores time information about a video frame of video data and the index list of offset data; a control unit which determines a video frame localization mode according to the touch speed, the touch length, and the touch direction of the touch input, calculates the time information and the frame rate of a video frame to be displayed, and outputs control signals for a pusher, a decoder, and a frame buffer control unit; the pusher which acquires the offset information of the video frame based on the index list, reads video frame data according to the offset data, and pushes the read video frame data to the decoder; the decoder which maintains buffer arrays of the video frame data to be decoded, decodes the video frame data in the buffer arrays, and pushes the decoded video frame data to the frame buffer control unit; and the frame buffer control unit which stores the decoded video frame data and determines the point of time to display the current video frame according to the time information and the frame rate of the current video frame. [Reference numerals] (110) Touch detection module; (120) First storage unit; (130) Pusher; (140) Decoder; (150) Frame buffer control unit; (160) Second storage unit; (170) Render unit; (180) Control unit</p> |
