Abstract: A processing device and method for time domain change of A/V data stream comprises a starting threshold setting unit for setting a starting threshold; a detecting module for detecting whether the A/V data stream having a SCR domain change; a counting unit comprising a counter for recording a continuous probable times of the SCR domain change according a detecting result of the detecting module; a comparing unit for comparing the counter with the starting threshold; and a time domain change procedure performing unit for performing a time domain change procedure of the A/V data stream for synchronization of a STC according a detecting result of the comparing unit. Accordingly, since the frequency of the time domain change will be lower, the corresponding response of the decoder will be in time for playing as well.

Abstract: A method for converting the MPEG 1 data format to the MPEG 2 data format is provided. The method includes reading and mapping the MPEG 1 data format to the MPEG 2 data format to generate a first title file and a second title file. Sequential playback functions defined in the Video 1.1 specification is supported when the first title file is selected for playback. Otherwise, playback controls functions defined in the Video 2.0 specification is supported when the second title file is selected for playback.

Abstract: A mix mode multimedia player having audio scenery and video scenery thereof being controlled individually comprises a playback manager module, and a presentation engine module. The playback manager module for generating audio-format play list, video-format play list, and audio-video interlaced-format play list according to user settings. The user settings includes a plurality of media file's names that user desires to play. The presentation engine module has an audio scene state machine, and a video scene state machine, wherein the presentation engine module provides corresponding play sequences to the audio scene state machine, and the video scene state machine. Furthermore, the audio scene state machine can thus play the media files with audio format and said video scene state machine can thus play said media files with video format.

Abstract: A method of preventing playing of audio or video data from being interrupted for a mix mode multimedia playback system comprises the following steps: a video stream buffer, a audio stream buffer, and a parser module is provided; then amount of free space in the video stream buffer is checked so as to ensure the amount of the free space is larger than a sum of a track buffer and video data being processed by the parser module. Whenever the playing of an audio scene state machine is paused or stopped, audio data processed by the parser module and audio data in the track buffer are pushed into the free space of the audio stream buffer so as to release entire space of the track buffer for video data to be loaded.

Abstract: A method for choosing the first candidate to be loaded from a series of job requests for a mix mode multimedia player is disclosed. A job table having a plurality of rows is provided. Each row for a job has a job message with a “Priority” status, a “Usage status” status, and an “Examining function” status. The jobs are generated by a loader manager module of the mix mode multimedia player according to the job requests. The job messages of the jobs are arranged according to the “Priority” status in order. Then, the first candidate is chosen according to the following steps. The “Usage status” status of the job message is examined. If the “Usage status” is “used”, the “Examining function” status of the job message is examined. At last, If the “Examining function” status is “Critical”, the job is set as the first candidate.

Abstract: A system and method is provided for displaying multimedia information used in suspending mode according to preset timing in a calendar. In one form, a real-time clock is used to generate a real-time clock signal so as to make the multimedia player being synchronous with the real world. A memory device is used to store encoded multimedia information while a calendar is still included therein for saving timing information set by the manufacturer and user. A data-accessing module is used to access corresponding multimedia information from the memory device according to a comparison result by comparing the timing information provided by the rear-time clock with the calendar. A decoder decodes the aforesaid multimedia before delivering to a display system.
