摘要： An simulator particularly suited for simulating the hardware/software behavior of embedded systems. The architecture of the simulator permits the hardware and software systems to be modeled as modules with well characterized behaviors. A concise module definition syntax is used to describe module behaviors, and a translator operates upon the module to abstract operations of module behaviors at a level which does not require cycle-based, direct interaction of each module with the underlying simulation engine.

摘要： A method and apparatus for concealing errors during decoding of a video bit stream utilize estimates, if possible, motion vectors in the temporal domain. If estimation in the temporal domain is not possible, motion vectors are estimated in the spatial domain. A macroblock is then estimated based upon the estimated motion vector. If estimation in the spatial domain is not possible, macroblock estimation is made without the use of an estimated motion vector.

摘要： A digital video processor and operating method for a receiving raw audio and video data representing images and sound to be played. The processor includes a demultiplexer for receiving the raw audio and video data and providing demultiplexed audio and video data to a memory. A first system time clock provides first time values in response to being continuously clocked by the demultiplexer. A CPU decodes and plays back the audio and video data as a function of the audio and video PTS values. The processor further includes a second system time clock providing second time values in response to being periodically incremented by the CPU. The CPU periodically sets the second system time clock to a second time value equal to a current first time value of the first system time clock in response to a standard play mode, and the CPU periodically sets the first system time clock to a first time value equal to a current second time value of the second system time clock in response to a trick play mode.

摘要： A method and apparatus for synchronizing the playback of audio and video frames from a program source. The method associates an audio presentation time stamp ("PTS") value with an output audio frame. Selected ones of audio and video data packets include respective audio and video PTS values representing desired playback times of the respective audio and data associated therewith. The selected ones of the audio data packets further include audio frame numbers representing a number of output frames of audio to be played back between the selected ones of the audio data packets. The method comprises the steps of first storing the audio and video PTS values in respective audio and video PTS tables during an audio demultiplexing process. In addition, the audio frame numbers are stored in frame counters in association with respective PTS values during the demultiplexing process. Thereafter, the process sequentially decodes the audio and video input data to produce respective frames of audio and video which are presented to the user. With the presentation of each audio and video frame, the respective audio and video frame counters are selectively decremented. Upon detecting one of the audio frame counters having a zero value, the audio PTS value for that zero value audio frame counter is retrieved. Thereafter, the playback of the audio and video frames is selectively modified so that frames of audio and video are played back in synchronization.
摘要翻译：一种用于使来自程序源的音频和视频帧的重放同步的方法和装置。该方法将音频呈现时间戳（“PTS”）值与输出音频帧相关联。所选择的音频和视频数据分组包括表示与其相关联的相应音频和数据的期望回放时间的相应音频和视频PTS值。所选择的音频数据分组还包括表示在所选择的音频数据分组之间要播放的音频的输出帧数的音频帧号。该方法包括以下步骤：在音频解复用处理期间首先将音频和视频PTS值存储在相应的音频和视频PTS表中。此外，在解复用处理期间，音频帧号与相应的PTS值相关联地存储在帧计数器中。此后，该处理顺序解码音频和视频输入数据，以产生呈现给用户的相应的音频和视频帧。随着每个音频和视频帧的呈现，相应的音频和视频帧计数器被选择性地递减。在检测到具有零值的音频帧计数器之一时，检索该零值音频帧计数器的音频PTS值。此后，选择性地修改音频和视频帧的重放，使得音频和视频帧同步地重放。
