  • Bi-directional indices for trick mode video-on-demand
    Patent number: 7853980
    Abstract: A method of storing digital video content to facilitate trick play consistent with certain embodiments involves storing inter-coded frames of the content in a first file and storing intra-coded frames of the content in a second file. A set of forward indices are used to address the intra coded frames in a forward direction such that playback of the second file in the order of the forward indices simulates a fast-forward playback. A set of reverse indices are used to address the intra-coded frames in a reverse direction such that playback of the second file in the order of the reverse indices simulates a fast-reverse playback. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

  • Disk playback apparatus and stepping-motor control apparatus
    Patent number: 7852036
    Abstract: When the magnitude of a traverse signal exceeds a predetermined level, the value of a microstep drive signal is changed by one microstep angle so that the rotation angle of the stepping motor changes in a rotation direction in which the magnitude of the traverse signal decreases. A determination is made as to whether or not the magnitude of the traverse signal becomes a predetermined level or less. When the magnitude of the traverse signal does not become the predetermined level or less, the magnitude of the microstep drive signal is returned to the pre-change value and the value of the microstep drive signal is incremented by an additional microstep angle so that the rotation angle of the stepping motor changes in a rotation direction in which the magnitude of the traverse signal decreases.
