  • Patent number: 8675138
    Abstract: A method and system are provided in which a processor may perform fast source switching and/or automatic source switching by keeping active the signals from multiple sources. The processor may determine which received video signals are locked-in within a front-end portion of the processor. A video signal may be locked-in when a demodulator is locked to a carrier in the video signal or when a decoder is programmed to decode the video signal. During operation, the processor may switch from processing a current video signal to processing a video signal selected from those determined to be locked-in. The processor may maintain active a portion of a back-end portion of the processor to handle the switch from the current video signal to the selected video signal. The processor may switch to process between video signals when a predetermined content and/or metadata is detected within one of the video signals.

    Abstract: According to a picture-in-picture (PIP) system and method, a first image sensor device detects light from a first subject and generates a first signal indicative of image data for the first subject. A second image sensor device detects light from a second subject and generates a second signal indicative of image data for the second subject. Overlay logic combines the first and second signals to generate a picture-in-picture signal indicative of a combination of an image of the first subject and an image of the second subject, wherein the overlay logic is located within the first image sensor device. The first image sensor device generates a synchronization signal which is received by the second image sensor device and triggers the second image sensor device to generate the second signal indicative of image data for the second subject.

  • Patent number: 8477149
    Abstract: A method, system and computer readable media for real-time chromakey matting using image statistics. To identify the chroma key spectrum, the system/method executes in three stages. In an off-line training stage, the system performs semi-automatic calibration of the chroma key parameterization. In the real-time classification stage, the system estimates the alpha matte on a GPU. Finally, an optional error minimization stage improves the estimated matte, accounting for misclassifications and signal noise. Given the resulting matte, standard alpha blending composites the virtual scene with the video feed to create the illusion that both worlds coexist.

  • Publication number: 20130155325
    Abstract: A method and computing device that allows a viewer to specify a Region of Interest (ROI) in a picture-in-picture (PIP) video signal, and displays only the ROI in the PIP window. The method displays a secondary video signal for a secondary program, and receives a boundary that defines an ROI on the secondary video signal. The method extracts a portion of the secondary video signal, where the portion extracted corresponds to the ROI. The method displays a primary video signal for a primary program in a main window, and displays the extracted portion of the secondary video signal in the main window where the portion of the secondary video signal overlays the primary video signal.

  • Patent number: 8442121
    Abstract: A method, apparatus and system are provided for controlling a scene structure of a mobile terminal for receiving and displaying data streams in a mobile broadcast system. When logical channels are multiplexed into one physical channel, the multiplexed channels are sequentially decoded and are displayed on an image. A channel circulation scene alternately displays the channels on one image in designated order. In a combination scene structure, a new node is added to a conventional Lightweight Application Scene Representation (LASeR) technology. To compose a scene, fields for time information and scene transition effect are provided. A delay time due to a channel change is reduced. A multi-channel image is effectively provided to address a problem when a user retrieves service content while directly switching a channel. The terminal dynamically composes the multi-channel image using stream source node information from a service provider without an additional mosaic channel.

  • Patent number: 8428140
    Abstract: In a method for the video coding of image sequences images in the image sequence are coded in a scaled manner, in such a way that the video data produced contains information which permits the images to be represented in a plurality of differing stages of image resolution, the latter being defined by the number of pixels per image representation. The coding is block-based, in such a way that to describe a displacement of parts of one of the images, said displacement being contained in the image sequence, at least one block structure that describes the displacement is created. Said block structure is configured from one block, which is subdivided into sub-blocks, whereby some of the sub-blocks are further subdivided into successively smaller sub-blocks. A first block structure is temporarily created for at least one first resolution stage and a second block structure is created for a second resolution stage, the first resolution stage having a lower number of pixels than the second resolution stage.
