Abstract: Aspects of the disclosure are directed to a novel approach for content protection. Specifically, various embodiments employ data feeds to continuously or periodically inform placeshifting devices of protected content. The placeshifting devices then filter or otherwise block the protected content from being re-transmitted over a network based on this information. In some embodiments, the data feeds take the form of Really Simple Syndicating (RSS) or Atom feeds. These data feeds may carry information about the protected content, such as the time, the title, and the channel of specific audio/video protected content. Based on this information, the placeshifting device can determine which content is protected and not eligible for re-transmission.

An on-screen user interface of a display device may be enhanced with on-screen indications that indicate the position of the respective audiovisual content. For example, a user interface may provide an arrow in the lower-left portion of the screen to correspond to audiovisual input obtained from a device connected to the lower-left portion of the display device housing. A listing of input sources arranged by position relative to the display device and appropriate previews of the audiovisual content from the sources may also be incorporated into the user interface. In further examples, determined labels and human-readable identifiers for the respective input sources may be coordinated with the listing of input sources arranged by position.

Abstract: A system and method for generating a projected image signal encoded with position information. The temporal pixel-location data is hidden within visible light signal used for regular image projection. This enables the user to utilize one or multiple ring-shaped light receivers to implement touch or multi-touch functions on a regular image content generated using light from the same projector. The temporal light signal generated by the projector is sliced into multiple temporal segments. The segments include segments of two different types. A segment of the first type is used for carrying a temporal position signal of each pixel in the projector signal. On the other hand, a segment of the second type is used to adjust the color of each pixel. With the color adjustment segment projected to each image pixel, a meaningful visible content of a regular image can be displayed despite the presence of the position-encoded signal segments.
