  • Publication number: 20080256360
    Abstract: A device such as a mobile receiving unit (28) may include a memory (74) having a software image (106) therein. The memory (74) has a first stored signature (104) therein. A controller (60) may include a boot loader module (69) that generates a second signature from a portion of the software image (102A-E) less than a full image. The controller (60) authenticates the software image using the first signature and the second signature.

  • Publication number: 20080115180
    Abstract: A communication system (10) includes a controller (10, 160) for communicating a selection list to a wireless device (28, 36). The wireless device includes a user interface (280) for selecting a selection from a selection list (452). The wireless device generates a selection signal in response to selecting and wirelessly transmits the selection signal to the controller (100, 160). The controller (100, 160) wirelessly transmits content corresponding to the selection signal to the wireless device. The controller (100, 160) may be a business service controller or a local communications controller.

  • Publication number: 20070171137
    Abstract: A vehicle 16 includes a vehicle body 30. A satellite antenna 18 is mounted within the vehicle body 30. A satellite transmissive panel 40 is coupled to the vehicle body 30 adjacent to the antenna 18. The satellite antenna may be mounted within the passenger compartment 20 or within the trunk 90 of the vehicle 16.

  • Patent number: 5600376
    Abstract: Video signal compression apparatus includes a memory for storing two fields of image data and providing fields of image data separated by one frame intervals. Frames of video signal are composed from the respective ones of the fields. The field types (e.g., odd or even) of respective fields are determined. Flags are associated with composed frames to indicate if a field of respective frames may be repeated upon reproduction, and which field of the composed frames should be displayed first.

  • Patent number: 5491516
    Abstract: Video signal compression apparatus includes a memory for storing two fields of image data and providing fields of image data separated by one frame intervals. Image data from corresponding fields of successive frames are subtracted to generate field differences. The field differences are accumulated over respective field intervals, and the sum is compared against a predetermined value. If a sum of differences over a field is less than the predetermined value, the most recent field is considered to be redundant and may be excised. After respective fields are excised, frames of video signal are composed from the remaining fields. The field types (e.g., odd or even) of the fields in the memory are determined, and the data is accessed from the respective fields in memory such that data from odd and even fields occupy odd and even lines in the composed frames respectively.

  • Patent number: 5384599
    Abstract: A television signal receiver processes a television signal representing a letterbox image display format with a main image region, and a bar region containing auxiliary information to help convert from interlaced to progressive scanning. The auxiliary information is processed in a signal path including a nonlinear amplitude expander and apparatus for modifying the operation of the signal path as a function of the noise content of the television signal.

  • Patent number: 5317398
    Abstract: A film/video detector includes circuitry for generating the differences between corresponding pixel values in successive frames of video signal. These differences are accumulated over respective frame intervals. Accumulated values for respective frames are applied to a signal averager and to a correlation circuit. Average values from the averager are subtracted from correlation values from the correlation circuit, and film mode signal is indicated if the latter differences are greater than a predetermined value.

  • Patent number: 5235417
    Abstract: A television receiver processes a television signal representing a letterbox image display format with an image region, and a bar region containing "helper" information to help convert from interlaced to progressive scanning. An image signal processing path contains a motion detector and switch for determining whether a video processor receives image information (in the presence of motion), or field repeated information (in the absence of motion). Another motion detector associated with helper signal processing exhibits a narrower motion spreading characteristic than the motion detector in the image path, and determines when the helper signal is coupled to the image path.

  • Patent number: 5225907
    Abstract: A television signal receiver processes a television signal representing a letterbox image display format with a main image region, and a bar region containing auxiliary "helper" information to help convert from interlaced to progressive scanning. In the presence of image motion, a main image component and the helper component are combined and conveyed to a video processor. In the absence of motion, other image information, e.g., field repeated information, is conveyed to the video processor. The information conveyed to the video processor is determined by a switching network responsive to an control signal from a motion detector which senses low frequency luminance image information substantially exclusive of high frequency image information.
