  • Rate control for real time transcoding of subtitles for application with limited memory
    Patent number: 8311101
    Abstract: An apparatus comprising an estimation circuit, a rate control circuit, a queue circuit, and an encoder circuit. The estimation circuit may be configured to generate a size value in response to an input signal comprising (i) a plurality of frames and (ii) a plurality of embedded subtitle elements. The rate control circuit may be configured to (i) generate a control signal, (ii) pass through the plurality of frames, (iii) present a first one or more of subtitle elements for current processing in response to the size value, and (iv) present a second one or more of subtitle elements for subsequent processing. The queue circuit may be configured to (i) receive the second one or more subtitle elements, (ii) present the second one or more of subtitle elements for current processing when the control signal is in a first state and (iii) hold a second one or more subtitle elements for subsequent processing when the control signal is in a second state.

  • Method and/or apparatus for color space reduction for transcoding subpicture elements
    Patent number: 7688333
    Abstract: An apparatus including a first circuit, a second circuit and a third circuit. The first circuit may be configured to collect color statistics. The second circuit may be configured to sort colors based upon the color statistics collected by the first circuit. The third circuit may be configured to generate a mapping function between the sorted colors and a color space of a receiving standard.
