  • Patent number: 10602153
    Abstract: Various of the disclosed embodiments relate to multiple video encoders that are used to simultaneously encode a video using encoders configured using different encoding parameters. A segment selector selects an encoded version of the encoded video segment using operational criteria such as video quality and bandwidth. A configuration determination module may analyze the video segment to make a decision about which encoding parameter configurations may be suitable for encoding the video segment. The configuration determination module may be trainable, based on past encoding results.

  • Patent number: 10523978
    Abstract: A content provider might be responsible for content transmitted over a large number of channels, including premium channels that may have fixed quality settings. In order to provide the appropriate quality, the encoders for the premium channels are able to obtain the bit rates (and other capacity) needed. The total bit rate used for the premium channels can then be compared against a maximum bit rate for all channels for the provider to determine a remaining bit rate. The remaining bit rate can then be allocated, evenly or otherwise, across the various non-premium channels. Transmission components such as statmuxes used for the non-premium channels can be configured to adjust the bit rates as necessary based at least in part upon the allocation. Such an approach enables the premium channels to provide the fixed quality ensuring that the aggregate bandwidth meets the bit rate limit.

    Abstract: A video surveillance system includes surveillance cameras; a video converting and combining unit; an encoder for encoding a combined video from the video converting and combining unit; a decoder for decoding the combined video transmitted from the encoder; a video converting and splitting unit for splitting the combined video decoded by the decoder into the videos captured by the surveillance cameras; and a display device for displaying the videos inputted from the video converting and splitting unit. When combining the videos into one combined video, the video converting and combining unit appends assignment information in which each of the surveillance cameras, rotation information indicating application of a rotation process, and division information indicating whether the corresponding video is a left half video or a right half video are associated with one another. The video converting and splitting unit splits an HD video into SD videos based on the assignment information.

  • Patent number: 10281391
    Abstract: A laser system containing an etalon to reduce the spectral bandwidth and for tuning, with cavity dumping to generate the short pulses is described. The resulting system is stable and not overly complicated. The combination of cavity dumping with an intracavity etalon enables the invention to produce a string of short pulses, each of which has a very narrow spectral bandwidth. Tuning the wavelength over a spectral range that is very small, but much larger than the laser's spectral bandwidth, enables the invention to use dual-wavelength lidar, DIAL, differential spectroscopy, or a combination of these methods to measure the concentration of the desired chemicals with excellent accuracy.

  • Patent number: 8228981
    Abstract: A method of encoding multi-view video using camera parameters and a method of decoding multi-view video using the camera parameters are provided. The method of encoding multi-view video using the camera parameters includes detecting the camera parameters from each of a plurality of video data input from a multi-view camera in predetermined video units, and adaptively encoding each of the plurality of the video data according to whether each video data has the camera parameters. Accordingly, it is possible to increase the efficiency of compressing video without degrading video quality.

  • Patent number: 8184688
    Abstract: A digital broadcasting reception apparatus and robust stream decoding method thereof. The digital broadcasting reception apparatus includes a robust decoder that decodes a robust stream of a dual transport stream where a normal stream and the robust stream are combined. The robust decoder includes a first decoder that trellis-decodes the robust stream; a robust deinterleaver that interleaves the trellis-decoded robust stream; a second decoder that convolution decodes the deinterleaved robust stream; a robust interleaver that interleaves the convolution-decoded robust stream; and a frame formatter that adds decoded data of the second decoder to a part that corresponds to a position of the robust stream of a frame where the normal stream and the robust stream are mixed. Accordingly, a receiver of a simple structure can be provided.

  • Patent number: 8175325
    Abstract: Watermark information (denoted WM) consists of several symbols which are embedded continuously by reference sequence modulation in an audio or a video signal. At decoder site the WM is regained using correlation of the received signal with a corresponding reference sequence. The symbols form watermark data frames. The invention uses for the bit values ‘zero’ and ‘one’ in each payload symbol and for each payload symbol in a watermark data frame different reference sequences, without using synchronisation symbols. A logarithmic search is performed in the WM decoder to reduce the numbers of correlations to be calculated. The invention makes watermarking of critical sound signals much more robust.

  • Patent number: 8111758
    Abstract: Disclosed is a stereoscopic/multiview three-dimensional video processing system and its method. In the present invention, stereoscopic/multiview three-dimensional video data having a plurality of images at the same time are coded into a plurality of elementary streams. The plural elementary streams output at the same time are multiplexed according to the user's selected display mode to generate a single elementary stream. After packetization of the single elementary stream continuously generated, information about the stereoscopic/multiview three-dimensional video multiplexing method and the selected display mode information are added to the packet header of the stream. Then the packetized elementary stream is sent to the image reproducer or stored in storage media.

  • Patent number: 8086088
    Abstract: The present invention is related to a digital video recording method, and in particular, when a recording mode is audio detection, according to an audio signal transmitted from a mike mounted on a camera or a mike mounted separately, this method records the video taken by said camera during the time period for which a recording speed and video resolution is already set as super-high speed and high video resolution. After the elapse of an already set time period, when the audio signal is sensed, this method records the video by varying the recording speed and video resolution from super-high speed and high video resolution into low-speed and low video resolution at a time interval which is already set. Therefore, it becomes possible to obtain the specific information about the video data which is important in an unmanned security system.
