Latest Patents
One of Hsien-Ming Tsai's latest patents is an "Apparatus and method for determining rendering duration of video frame." This invention provides a method and an apparatus for determining a rendering duration. An audio/video recording system is utilized for recording an audio bit stream and a video bit stream. The audio bit stream consists of multiple audio frames, while the video bit stream includes N video frames. The rendering durations of the first and last video frames are determined based on the moments when the system starts to record the audio and video frames. Additionally, if the (i+1)th video frame through the (i+N)th video frame are lost, the rendering duration of the ith video frame is determined based on N. Furthermore, when the system receives a command for synchronization correction for the ith video frame, the rendering duration is adjusted based on a correction value.
Another significant patent is the "Method and apparatus for estimating length of audio file." This method estimates the audio length of an audio file in an audio player. Initially, it generates a predicted audio length based on the average bit rate of selected audio frames in the audio file. An adjustable audio length is initialized by this predicted length. During playback, the method continuously calculates a latest reference audio length. If the variation between the latest and previous reference audio lengths is smaller than a predetermined threshold, the adjustable audio length is modified accordingly. Ultimately, an estimated audio length is acquired based on the ratio of the played data amount to the total data amount of the audio file.
