Abstract: A wiper is controlled to sweep a surface area, e.g., a portion of a windshield, in front of a camera, e.g., a camera mounted inside a vehicle. An image captured from the camera after the wiper completes, e.g., immediately completes, the sweep of the surface area in front of the camera is used in generating a depth map. In some embodiments a first wiper is controlled to clear a surface area in front of a first camera while a second wiper is controlled to clear a surface area in front of second camera at the same time, and the first and second cameras are synchronized to initiate image capture at the same time, capturing images through recently cleared area, and the captured images are used to generate a depth map. A vehicle control operation, e.g., a direction, braking or speed control operation is performed based on the depth map.

Abstract: A system of cameras can be used to generate a complete field of view within an edge network. For example, one camera can have a field of view where part of the view is obstructed by an object and/or by the camera's orientation. Yet another camera that is a part of the edge network can supplement the view of the first camera by providing an alternate view. The two views can be stitched together by a coordinate system such that a complete field of view can be utilized by both cameras. Additionally, where a field of view is not available by any stationary camera, the system can dispatch a mobile camera to help supplement the views.

Abstract: According to one embodiment, an electronic device includes a memory that stores a first EDID including an identification bit set to respond to a separate electronic device when the separate electronic device supports a first version of the HDMI, a transmitter that transmits the first EDID, and a receiver.

When the receiver does not receive the first control information, the compliant version of the HDMI to be operated is determined according to an attribute of a video and audio signal transmitted from the separate electronic device.

Abstract: An interlaced video signal can include content of different types, such as interlaced content and progressive content. The progressive content may have different cadences according to the ratio between the frame rate of the progressive content and the field rate of the interlaced video signal. Cadence analysis is performed to identify the cadence of the video signal and/or to determine field pairings when progressive content is included. As described herein, motion information (e.g. motion vectors) for blocks of fields of a video signal can be used for the cadence analysis. The use of motion information provides a robust method of performing cadence analysis.

Abstract: A mobile device responds in real time to media content presented on a media device, such as a television. The mobile device captures temporal fragments of audio-video content on its microphone, camera, or both and generates corresponding audio-video query fingerprints. The query fingerprints are transmitted to a search server located remotely or used with a search function on the mobile device for content search and identification. Audio features are extracted and audio signal global onset detection is used for input audio frame alignment. Additional audio feature signatures are generated from local audio frame onsets, audio frame frequency domain entropy, and maximum change in the spectral coefficients. Video frames are analyzed to find a television screen in the frames, and a detected active television quadrilateral is used to generate video fingerprints to be combined with audio fingerprints for more reliable content identification.

Abstract: Systems, apparatuses, and methods for scheduling beamforming training during vertical blanking intervals (VBIs) are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. The wireless link between the transmitter and the receiver has capacity characteristics that fluctuate with variations in the environment. To combat the fluctuating capacity characteristics of the link, the transmitter and the receiver perform periodic beamforming training procedures to determine whether to adjust the beamforming characteristics of their respective antennas. To avoid interfering with the video data being sent, the system waits until a VBI to perform a beamforming training procedure. If the beamforming training procedure cannot be completed in a single VBI, then multiple VBIs can be used for performing separate portions of the beamforming training procedure. In one embodiment, the system can perform a beamforming training procedure every N VBIs, where N is a positive integer.
