  • Patent number: 7075587
    Abstract: A video display apparatus with separate display means is provided so that the textual information can be displayed without preventing viewers from watching the full picture. The separate display means can be provided for a television receiver so that textual information, which includes closed caption text and subtitles, can be displayed on the separate display means without occupying the picture area. The separate display means can be provided for a screen in a movie theater so that subtitles can be displayed on the separate display means when a foreign movie is played. The separate display unit can be used to display other textual information, including a channel number, a name of the broadcasting station, the title of the current program and the remaining time of the current program.

  • Patent number: 7075985
    Abstract: Methods and systems for efficient video compression by recording various state signals of cameras. In accordance with the teaching of the present invention, a video camera with means to record the movement, zooming state, focus state, and aperture state of the video camera is provided. The luminous intensity, camera identification number and frame index are also recorded. These various state signals are recorded along with video and audio signals on recording media, such as magnetic tapes, memory cards, and hard drives in a predetermined data format. Additionally, video compression algorithms, which utilize such state signals to predict the current frame from previous reconstructed images, are provided. In particular, the information on the various states of the video camera is useful in obtaining accurate motion compensated images.

  • Publication number: 20040175056
    Abstract: New methods and systems for objective measurements of video quality based on degradation of edge areas are provided. By observing that the human visual system is sensitive to degradation around edges, objective video quality measurement methods that measure degradation around edges are provided. In the present invention, an edge detection algorithm is first applied to the source video sequence to find edge areas. Then, the degradation of those edge areas is measured by computing a difference between the source video sequence and a processed video sequence. From this mean squared error, the PSNR is computed and used as video quality metric.

  • Publication number: 20030161406
    Abstract: New methods for objective measurement of video quality using the wavelet transform are provided. The characteristic of the human visual system, which varies in spatio-temporal frequencies, is exploited to develop methods for objective measurement of video quality. In order to compute spatial frequency components, the wavelet transform is applied to each frame of source and processed videos. Then, the difference (squared error) of the wavelet coefficients in each subband is computed and summed, producing a difference vector for each frame. By applying this procedure to the entire frames of source and processed videos, a sequence of difference vectors is obtained and the average vector is computed. Each component of this average vector represents a difference in a certain spatial frequency. In order to take into account the temporal frequencies, a modified 3-D wavelet transform is provided. In either case, a single vector represents the difference between the source and the processed videos.
