摘要： 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. The encoder circuit may be configured to generate an output signal in response to (i) the plurality of frames, (ii) the first one or more subtitle elements, and (iii) the second one or more subtitle elements.
