    摘要: A single-chip application specific integrated circuit provides autonomous management of playback of digital video and audio. The chip includes a digital video decoder and output system, and a central processing unit controlling said digital video decoder and output system. The central processing unit receives commands to establish a current playback state for management of playback of digital video and audio by said digital video decoder and output system, and responds to a video field synchronization signal and a current playback state, without external instruction, to determine whether to display digital video, whether to decode digital video for display, whether to repeat display of previously decoded digital video, and whether to skip over digital video prior to decoding digital video for output. By delivering commands to the central processing unit, the application specific integrated circuit can be caused to transition between playback states to provide desired playback of said digital video and audio.

    摘要: A decoder decodes full frame MPEG-2 video by a single method that applies regardless of buffer memory and frame rate conversion considerations. A display control module handles frame rate and field sequence in response to host configuration, trick play command signals, and information in the received bitstream. Pictures are decoded as buffer memory for the decoded pictures becomes available, and picture display attributes are assigned and stored in a table, one string for each decoded picture. Frame rate and field sequence are managed in light of memory constraints, to produce a high quality result without re-decoding data.

    摘要: A digital video presentation system is provided with a decoder to decode full frame MPEG-2 video by a single method that applies regardless of buffer memory and frame rate conversion considerations. A display control module handles frame rate and field sequence in response to host configuration, particularly buffer memory size and display type (NTSC or PAL), to host trick play command signals, and to information in the received bitstream. Pictures are decoded as buffer memory for the decoded pictures becomes available, and picture display attributes are assigned and stored in a table, one string for each decoded picture. Field display logic is informed of the to memory address of the next field to be displayed along with the attributes needed for affecting proper field display sequence, and flagging whether the memory is to be freed for use by the decoder as the field is being displayed and whether the decoder is to decode the next picture as the field is being displayed. Where memory is small, opposite field data can be output. Field sequence order is provided for output buffers in the range of from 0.53 to 0.67 frames in size, or a full frame in size. Buffer memory is optimized by maintaining tables of offset variables and accessing a fixed table of memory pointers as fields of data are being displayed. The offset data tables are identified to the display logic, which uses the data in the specified offset table to address rows of memory in which the consecutive rows of particular field to be displayed are stored. The decoder loads offset values into the offset tables as pictures are being decoded and rows of blocks of the picture are stored as memory becomes free.

    摘要: A DVD reproduction apparatus includes a video decoder capable of outputting smooth video data during forward or backward high-speed reproduction. The video decoder is intermittently supplied with data in VOBU (Video Object Unit) units. According to control by a controller, the decoder outputs the decoded I pictures or P pictures from a memory having a capacity of three or more pictures. In a case of forward reproduction, the pictures are outputted according to the time axis, and in a case of backward reproduction, the pictures are outputted in the opposite direction of the decoding order. Moreover, the decoder counts a VOBU passing time through a demultiplexer provided at a preceding stage and outputs respective pictures at averaged intervals. That is, because three pictures are outputted for each VOBU, pictures are outputted at an interval of the averaged VOBU passing time multiplied by ⅓.

    摘要: Conventionally, a particular countermeasure has been taken for each of the error factors. That is, each error requires a circuit and the like for carrying out the countermeasure, which leads to an increase size of the entire circuit. The present invention includes a controller 14 which resets a system time clock STC serving as the system reference time with a time management information PTM in a video decoder 7. This reset time is compared to a time management information PTM or DTM of the video decoder 7 or an audio decoder 11. According to a result of the comparison, the synchronization lag between the video signal and the audio signal is controlled.

    摘要: According to one embodiment, an image generation unit generates a first image during a large aperture period and a second image during a small aperture period. An image combining unit generates a composite image based on the latest second image and the specific first image. A display unit displays the composite image in real time. A determination unit determines whether to update the first image based on an index associated with the anatomical positional shift between the first image and the second image. A driving control unit enlarges a aperture to the large aperture, when the determination unit determines to update, and maintains the aperture at the small aperture, when the determination unit determines not to update.
