    摘要： Techniques for controlling switching of a barrier component for efficiently displaying various types of 2-D content and 3-D content on a projector screen are presented. A barrier control component detects an optical signal in a control region of the projector screen that is providing visual content to the barrier component, and identifies the type of visual content, such as 2-D content or 3-D autostereoscopic content, based on the optical signal. The barrier control component identifies a control signal based on the identified content type, and transmits the control signal to the barrier component via a wireline or wireless connection. The barrier component is controlled to automatically switch to a desired mode, such as 2-D mode or 3-D autostereoscopic mode, and employ a desired barrier pattern, in response to the received control signal. The barrier component is powered using a solar cell component that generates power using the optical signal.

    摘要： Methods and systems for producing ambient light effects based on video content are provided. A method of producing an ambient light effect includes providing a receiving device including a processor configured to parse incoming video content and receiving the video content including a plurality of scenes at the receiving device. The method further includes parsing the incoming video content and detecting at least one scene in the video content for association with at least one ambient light effect. The method also includes generating a command specifying at least one ambient light effect to be associated with at least one scene and sending the command from the receiving device to at least one lighting device in communication with the receiving device to generate at least one ambient light effect associated with at least one scene when the scene is displayed to a user.

    摘要： An ambient controller system and a method of determining an ambient parameter set associated with a textual description are described. A database (19) comprises a plurality of files having content in the form of a picture, video, or even sound. Furthermore, each file comprises information related to a file content, e.g. in the form of a file name, or other attributes which are stored as part of the file. The textual description is used for obtaining a subset of files whose information matches the textual description (16). The method further comprises analyzing the subset of files (17) for obtaining the ambient parameter set related to the textual description. The ambient parameter set may then be used to control one or more ambient devices (15).
