    摘要： In a motion picture subtitle system a shutter such as a mechanical dowser, LCLV, or E/0 diffuser is inserted in the optical path between the supplemental projector and the motion picture screen and synchronized to the projection of the subtitles to reduce visual artifacts and enhance the cinematic presentation. A controller is arranged to receive the subtitles from a storage medium, to provide the subtitles to the supplemental projector in synchronism with the projection of the motion picture, and to alternately cause the shutter to pass the modulated light beam during an "on" state in synchronism with the motion picture so the subtitles are superimposed at desired times on desired portions of the motion picture and cause the shutter to attenuate the light beam during an "off" state.

    摘要： An audio codec losslessly encodes audio data into a sequence of analysis windows in a scalable bitstream. This is suitably done by separating the audio data into MSB and LSB portions and encoding each with a different lossless algorithm. An authoring tool compares the buffered payload to an allowed payload for each window and selectively scales the losslessly encoded audio data, suitably the LSB portion, in the non-conforming windows to reduce the encoded payload, hence buffered payload. This approach satisfies the media bit rate and buffer capacity constraints without having to filter the original audio data, reencode or otherwise disrupt the lossless bitstream.
