    Abstract: The frequency of a digital data signal, such as a digital video signal, is intentionally varied or hopped before being sent over a network. This frequency hopping may be performed in accordance with a frequency hopping pattern shared with only intended receivers. The digital data signal may be further intentionally pre-distorted in accordance with a pre-distortion pattern which is also shared with only intended receivers. The frequency hopping and/or the pre-distortion patterns may be used to vary the frequency and modulation, respectively, on a periodic basis, such as a symbol-by-symbol or packet-by-packet basis.

    Abstract: According to one embodiment, the invention is directed to a method for securing communications with an electronic device. The method comprises obtaining a dynamic, non-repeating value from internal logic within a remote control. Thereafter, information including the non-repeating value is encrypted to produce an encrypted value, which is transmitted along with a radio frequency (RF) command from the remote control in order to restrict wireless control of the electronic device.

    Abstract translation: 根据一个实施例,本发明涉及一种用于确保与电子设备的通信的方法。 该方法包括从远程控制内的内部逻辑获得动态的非重复值。 此后,包括非重复值的信息被加密以产生加密值,该加密值与来自遥控器的射频(RF)命令一起发送,以便限制电子设备的无线控制。

    Abstract: Apparatus for identifying video content includes a scene detector to detect a plurality of consecutive scenes in the video content. The video content may include a video program and an advertisement contained within the video program. A signature generator determines a scene change signature for each of the plurality of consecutive scenes. A content identifier provides the plurality of scene change signatures to a comparator that compares the plurality of scene change signatures to a database having a plurality of video content items to identify the video program. The database includes an ordered plurality of previously determined scene change signatures for each item of video content in the database. The content identifier receives an identification of the video content from the comparator. The content identifier may further receive information related to a position of the plurality of scene change signatures within the ordered plurality of previously determined scene change signatures.

    Abstract: An arrangement is provided where a media server temporarily stores a DRM license that is associated with downloaded media content prior to copying the DRM license to a physical archival medium such as an optical disc. When the media server confirms that the DRM license is successfully copied to the physical archival medium, it destroys the temporarily stored DRM license.

    Abstract: A radio frequency receiver includes a receiver circuit for processing RF signals, an antenna to receive millimeter wave RF signals, and an attenuator circuit, coupled between the receiver circuit and antenna. In one embodiment, the attenuator circuit may be used to determine a signal strength of the millimeter wave RF signals, compare this signal strength to a first threshold value. If the signal strength is above the first threshold value, a level of attenuation applied to the millimeter wave RF signals may then be increased.

    Abstract: A system for sending multimedia data between a first High Definition Multimedia Interface (HDMI) component and a second HDMI component that is engaged with a displayer of multimedia data includes a first Digital Visual Interface (DVI) component receiving HDCP-encrypted multimedia data from the first HDMI component over a wire. A wireless transmitter sends data from the first DVI component to a wireless receiver, preferably at 60 GHz, and the receiver in turn sends the data to a second DVI component. Neither DVI component encrypts or decrypts data. The second DVI component sends the multimedia data to a second HDMI component for decryption and display on, e.g., an LCD or plasma display.
