    摘要： A display apparatus and a method of controlling the display apparatus are disclosed. The display apparatus includes: a signal receiver configured to receive a signal containing video data of a series of frames and corresponding sound data; a first data extractor configured to extract caption data from the signal; a second data extractor configured to extract the video data and the sound data from the signal; a buffering section configured to buffer the extracted video data; a sound-text converter configured to convert the extracted sound data into a text through sound recognition; a synchronizer configured to compare the converted text with the extracted caption data, and synchronize the caption data with frames corresponding to respective caption data among frames of the buffered video data; and a display configured to display the frames synchronized with the caption data.

    摘要： A slow Phase Locked Loop (PLL) is utilized to prevent an abrupt change to a video display containing multiple images when the source of the synchronization is changed. Such displays include Picture in Picture (PIP) television systems and computer displays. By appropriate buffering and memory management, visual disruptions can be minimized by slowly synchronizing the display synchronization signals to the new synchronization source. The slow synchronization also produces a less disruptive visual image when the source, or channel, of a single image display is changed, and allows for smooth visual transitions on displays having inertial elements, such as color wheels.

    摘要： In order to synchronize two dissimilar video formats, two or more phase locked loop circuits (PLL's) may be used in tandem. A first PLL circuit (202) may be connected to the first video format (Master) and generate an intermediate frequency (262). A second PLL circuit (204) may use the intermediate frequency as the timebase for generating the pixel clock (264) for the second video format (Slave). One or more Slaves may be connected to the generated pixel clock. The video synchronizing device may be a part of a graphics system, such as a graphics accelerator.

    摘要： An image processing apparatus, which displays an image corresponding to a synchronizing frequency change-image signal, which is obtained by changing a frequency of a synchronizing signal of an image signal, and an other image corresponding to an other image signal on a same display screen. The apparatus comprises a monitoring device and a synchronizing control device. The monitoring device monitors temporal relationship between the synchronizing signal of the synchronizing frequency change-image signal and a synchronizing signal of the other image signal. The synchronizing control device performs frequency regulation for the synchronizing frequency change-image signal based on the monitoring results from the monitoring device so as to prevent one of the synchronizing frequency change-image signal and the other image signal from passing the other thereof on the display screen.
