摘要:
Machine learning is applied to both 2D images from an infrared imager imaging laser reflections from an object and to the 3D depth map of the object that is generated using the 2D images and time of flight (TOF) information. In this way, the 3D depth map accuracy can be improved without increasing laser power or using high resolution imagers.

An audio video device (AVD) such as a smart TV allows profiles to be defined on the TV. A user accessing the TV can select one of the profiles to have the TV instantly configure itself for the accessing user. This is useful not only for the hearing-impaired but also visually-impaired people, who may encounter difficulty navigating profile setup menus.
摘要:
Each of plural devices includes a laser emitter and a camera for detecting reflections of laser light emitted by the device, so that plural of the devices can generate their own depth maps showing images within the field of view of their cameras. The resulting 3D depth maps from multiple cameras at potentially arbitrary locations can be aggregated to create a more accurate 3D depth map of the area covered by all the individual cameras. Each device/camera may be assigned a unique identification such as a unique number and a mechanism to identify, either electronically or visually, devices in its field of view. Using this information, the relative locations of the cameras can be calculated for purposes of aggregating the multiple depth maps.

Multiple camera systems which use laser illumination for ranging benefit from a heartbeat to synchronize the timing of the individual lasers to eliminate collisions of multiple simultaneous laser emissions. An optical micromesh system provides for the dynamic entry and egress of mobile and stationary nodes. The optical communication between nodes may be controlled using time domain multiplexing (TDM) to avoid cross talk and communication collision due to overlapping laser illumination. By using an optical, laser based micromesh network, laser ranging can be used to dynamically map node location.

Systems and methods for determining location of a digital broadcast receiver. The system includes the digital broadcast receiver receiving digital broadcasting, and at least one computing device configured to determine a location of the device. In one embodiment the receiver communicates with the at least one nearby location-enabled device and receives a device location. In one embodiment the system uses acoustic pings to determine the proximity of the device to the receiver.
摘要:
First and second brightness metadata pertaining to respective first and second contents are accessed, and responsive to receiving a command to change presentation from the first content to the second content, a composite brightness is established using the first and second metadata. At least one of the contents using the composite brightness at a start time of a transition period. During the transition period, video is presented using a changing brightness that starts at the composite brightness at the start time of the transition period and ends at the second brightness at an end time of the transition period. Subsequent to the end time of the transition period, the second content is presented using the second metadata and not using the first metadata.
摘要:
Content substitution and/or picture-in-picture technology is used to provide a sign language window that provides a sign language interpretation of audio content in main program audio/video content. The sign language window can be selectively disabled by a user that does not wish to view the sign language video. Also, in some implementations, the user can move the sign language window to a desired location on the display. The desired location may be one of a plurality of pre-defined display locations. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
摘要:
To eliminate the need for a user to laboriously enter device setup parameters into each of plural devices, a user ID is provided with a secure part, having the user's login credentials, and an unsecure device parameter part which defines device parameters desired by the user to be set in computing devices.

A purchaser of a CE device informs a retail clerk at the point of sale (POS) of features of the CE device the purchaser wishes to employ, some of which require a license. The CE device is vended without the licenses but the clerk can upload the desired features to a server, which correlates the features to licensable components and which returns to the POS the license codes needed to enable the components. The codes can be provided to the CE device using RFID at the POS, or storing the codes on a removable storage at the POS and giving the storage to the purchaser, or by printing the codes as bar codes in the sales receipt at the POS and giving the receipt to the purchaser, who later scans the codes past a camera of the CE device to enable the associated licensable components.
摘要:
An audio-video display device can download from a third party server a licensable component on which a royalty is to be paid. Various methods are disclosed for accounting for royalties associated with downloading the licensable component to the client device between the third party server and a client device manufacturer server.
