摘要:
A 3-D picture signal is provided as follows. An image and depth components having a depth map for the image are provided, the depth map includes depth indication values. A depth indication value relates to a particular portion of the image and indicates a distance between an object at least partially represented by that particular portion of the image and the viewer. The 3-D picture signal conveys the 3-D picture according to a 3D format having image frames encoding the image. Extra frames (D, D′) are encoded that provide the depth components and further data for use in rendering based on the image and the depth components. The extra frames are encoded using spatial and/or temporal subsampling of the depth components and the further data, while the extra frames are interleaved with the image frames in the signal in a Group of Pictures coding structure (GOP).

An apparatus and method is disclosed for preventing a viewer from switching from a channel when an advertisement is being displayed on the channel. The apparatus and method comprises an advertisement controller in a video playback device that (1) prevents a viewer of a direct (non-recorded) broadcast from switching channels when an advertisement is displayed, and (2) prevents a viewer of a recorded program from fast forwarding the recorded program in order to skip past advertisements that were recorded with the program. A viewer may either watch the advertisements or pay a fee in order to be able to change channels or fast forward when the advertisements are being displayed.

A system of providing a three-dimensional [3D] graphical user interface on a 3D image device (13) is provided for controlling a user device (10) via user control means (15). The user control means are arranged for receiving user actions and generating corresponding control signals. A graphical data structure is provided representing a graphical control element for display in the 3D graphical user interface. The graphical data structure has two dimensional [2D] image data for representing the graphical control element, and also at least one depth parameter for positioning the 2D image data at a depth position in the 3D graphical user interface.

The present invention relates to a method of encoding a video data signal for use with a multi-view rendering device,a method of decoding the video data signal, the video data signal, an encoder of the video data signal, a decoder of the video data signal, a computer program product comprising instructions for encoding the video data signal and a computer program product comprising instructions for decoding a video data signal. The method of encoding provides (401) a first image (10) of a scene associated with a first viewpoint, a depth map (20) associated with the first image, metadata (30) for use in depth map processing or rendering one or more views for further viewpoints by the multi-view rendering device, and generates (404) the video data signal. The video data signal comprises video frames partitioned in sub-images comprising a sub-image based on the first image and a depth sub-image based on the depth map, and metadata encoded in a color component of the depth sub-image.

Disclosed are methods and apparatus for lighting control. Presence of an optical element (110, 310, 200 312, 710A-E, 712, 810) is identified over one or more LEDs (323, 327) and at least one property of the optical element is identified. At least one property of light output of light sources associated with and/or covered by the optical element with covered LEDs element is adjusted based on the property of the optical element.
摘要:
Disclosed are methods and apparatus for lighting control. One or more properties of light output are controlled based on user manipulation of a mobile computing device (110, 510) such as a mobile phone. Data from a mobile computing device may be utilized to implement lighting property adjustments for one or more LEDs (132) based on the data. The data may be user gesture data that is based on physical movement of the mobile computing device in space by the user.
摘要:
Methods, apparatus and computing devices are described herein for activatable lighting devices. In various embodiments, a composition of a lighting system may be ascertained based at least in part on a database (851, 951) of one or more lighting device records associated with one or more lighting devices (100, 600, 700, 800a, 800b, 900, 1000a, 1000b, 1000c) of the lighting system. In various embodiments, it may be determined, based on the ascertained composition, that a predetermined criterion is satisfied. In various embodiments, a communication may be issued in response to the determination. The communication may be configured to facilitate activation of a deactivated lighting device function of a lighting device associated with the lighting system.
摘要:
The present disclosure is directed to inventive methods and apparatus for lighting control and for providing effects upon activation/deactivation. For example, various methods and apparatus are described for controlling various selected properties of light emitted by an LED-based lighting unit (100) with multiple LEDs (102) using, for example, a dimmer switch (101) and/or a predefined sequence of energizing LEDs.
