Abstract: Mediacast video content detection systems and methods that analyze the image content data of mediacast source data flows that include a variety of replaceable video content segments and a variety of non-replaceable video content segments to detect one or more characteristics of the video content segments. Detection regions may be utilized to detect visual elements in the video content segments that provide information regarding one or more properties of the video content segments, such as program type, start times, end times, video content provider, title, and the like. Replacement video content segments may replace video content segments determined to be replaceable. A buffering scheme may be employed to inherently adjust asynchronicity between a broadcast or Webcast and a mediacast. Actual insertion of replacement video content segments may occur upstream of a content consumer device or at the content consumer device.

Abstract: Provided are an image processing method and apparatus, and an image reproducing method and apparatus. The image processing method includes receiving three-dimensional (3D) image data; generating additional information about the 3D image data; and inserting the additional information in a blanking interval of the 3D image data.

Abstract: A representative Device and Method for 3-D Display Control is disclosed. The method for controlling stereo image display is disclosed. That is, to receive an image input signal wherein the image input signal includes a first refresh rate; to convert a frame rate of the image input signal to generate an image output signal, wherein the image output signal includes a second refresh rate which is higher than the first refresh rate, and includes a first image signal, a first VBI (Vertical Blanking Interval), a second image signal, a second VBI, a third image signal and a third VBI; to output a control signal for a left eye shutter of shutter glasses during a duration between the first VBI and a part of the second image signal; and to output a control signal for a right eye shutter of the shutter glasses during a duration between a part of the third image signal and the third VBI.

Abstract: The vertical blanking period is an idle period in video transmission that was originally intended for allowing the trace back of an electron beam to its point of origin. When sending the video signal over a wireless channel, the wireless channel may remain free of transmission of data during this period. However, in wireless transmission of a video signal in general, and in the transmission of an essentially uncompressed video signal in particular, there is a need to use all the bandwidth available, especially when transmitting a high-definition video signal. Therefore, a method is taught for using the vertical blanking period of a video signal for modem maintenance.

Abstract: According to one embodiment, a method for blocking scenes with objectionable content comprises receiving incoming content, namely a scene of a program. Thereafter, using closed captioning information, a determination is made if the scene of the program includes objectionable content, and if so, blocking the scene from being displayed.

Abstract: Apparatus is provided by which a television viewer can view other images e.g. during commercials or main program. For example, during a commercial, a viewer may channel surf or surf the internet. A banner is provided on a viewing screen while the viewer watches these other images. In this way the advertiser providing those commercials can still reach those viewers who are channel or internet surfing. Also, the banner will indicate to the viewer when the commercial is over and the normal programming has resumed. In another embodiment, during the main program user can activate one or more small commercial windows and position them on the screen based on his preference, e.g. using a remote device. Information is communicated to a broadcaster by the viewer's video system indicating the above-mentioned commercial windows are open on the viewer's screen.

Abstract: Apparatus and method for processing a vertical blanking interval (VBI) signal and video signal are provided. An exemplary apparatus comprises a VBI decoder, a mixer, and a TV encoder. The VBI decoder is configured to receive and decode the VBI signal to generate a decoded VBI signal. The mixer is configured to mix the video signal and decoded VBI signal to generate a mixed signal. The TV encoder is configured to encode the mixed signal to generate a first TV compatible signal for TV display. After receiving the first TV compatible signal, the TV not equipped with a VBI decoder can display the contents of the video signal and VBI signal.

Abstract: A video signal and an audio signal are time division multiplexed, encrypted, and transmitted. A transmission side time-compresses the audio signal, multiplexes, encrypts, and transmits the time-compressed audio signal in a blanking period of the video signal. Control is performed using an audio signal data enable signal ADE, and an audio signal/video signal switch signal.

Abstract: A system that inserts subscriber identification information includes, in a preferred embodiment, a system with a memory for storing subscriber identification information and a processor configured to insert the subscriber identification information into a media presentation to improve traceability of copied presentations to a subscriber.

Abstract: A method of controlling transmission of data from a computer to a video client via an interface device, comprising: reading a register on the interface device to obtain a value indicating temporal proximity to an occurrence of a vertical blanking interval occurs, the value increased incrementally until a vertical blanking interval occurs, and then being reset; deriving a time value, the time value indicating the occurrence of a vertical blanking interval; sending an interrupt to a processor on the computer at the occurrence of the vertical blanking interval; and invoking code in response to an occurrence of the video blanking interval.

Abstract: A communication system and method for communicating teletext information to mobile stations. A wireless access protocol (WAP) server is coupled to a television station and receives a signal which includes teletext information from the station. The WAP server includes a teletext decoder which decodes the teletext information in the transmitted signal. The decoded information is stored in memory using a server controller. The controller receives information requests from a network interface coupled to the mobile stations. The controller accesses the teletext information stored in memory and transmits the information to the mobile station through the network interface.
