  • Patent number: 8064752
    Abstract: Some embodiments provide a method of processing digital video in a computer. The method receives a first video clip. It stores the first video clip at a first rate in a storage of the computer. From the first video clip, the method generates a second video clip that is at a second rate different than the first rate. The method then outputs the second video clip from the computer. In some embodiments, the first rate is the native rate that a camera originally shot at least a portion of the first video clip, and the second rate is an encoded rate. In some embodiments, the method generates the second video clip from the first video by using the 2:3:3:2 encoding format. Also, in some embodiments, the method outputs the second video clip as the method generates the second video clip.

  • Patent number: 8009963
    Abstract: This disclosure describes adaptive filtering techniques to improve the quality of captured imagery, such as video or still images. In particular, this disclosure describes adaptive filtering techniques that filter each pixel as a function of a set of surrounding pixels. An adaptive image filter may compare image information associated with a pixel of interest to image information associated with a set of surrounding pixels by, for example, computing differences between the image formation associated with the pixel of interest and each of the surrounding pixels of the set. The computed differences can be used in a variety of ways to filter image information of the pixel of interest. In some embodiments, for example, the adaptive image filter may include both a low pass component and high pass component that adjust as a function of the computed differences.

    Abstract: The recording operation can be rapidly started and a notification about the operating state during the recording operation can be realized without adding a new component, whereby a target scene of a subject can be recorded reliably. When a video signal captured by a camera unit 10 is compressed and encoded and is recorded on a DV tape, a control unit 100 controls a compression/decompression unit 40 and a tape deck unit 60 to compress and encode the video signal and record as DV data without using compressed data already recorded on the DV tape. In other words, the control unit 100 controls the operation of compressing and encoding video data to be newly recorded in such a manner that compressed data already recorded on the DV tape is not read out, thus reducing the time until recording of the video data on the DV tape is started.

    Abstract: A new approach is proposed that contemplates systems and methods to support video-aware screen capture and compression. More specifically, the video-aware approach first detects whether or when video content is being actively played back on a screen of a hosting device. If the video content is actively being rendered, the approach separates (segments) the screen content into static (non-video) content and video content, The approach then applies video-specific capture and compression methods to the video content of the screen and other suitable compression methods to the non-video content of the screen. The compressed static and video content of the screen are separately and independently transmitted across the network to remote computing devices and are then decompressed and processed to reconstruct screen of its original content for display at the screens of the remote computing devices.
