Abstract: Doppler LIDARs, such as those used in ADAS (advanced driver assistance system) and autonomous vehicles, may need to sense objects at many directions. Some of the Doppler LIDAR devices use mechanically moving parts to scan over a range of directions and the various directions are not sensed simultaneously but sensed in turns over time. Mechanical moving parts generally have higher costs, lower reliability and shorter Mean Time To Failure (MTTF). The LIDAR sensor on chip with Doppler-sensing pixels disclosed herein uses a Doppler sensing-chip that enables Doppler LIDAR devices to sense many directions simultaneously in parallel without having to use mechanical scan and mechanical moving parts, even without having to use electronic scan. Lower costs, higher reliability, and faster detection time as well as higher direction sensing accuracy are objectives of this invention.

Abstract: A media server is hosted in a service provider's network so that media content can be stored from or rendered to a private network such as a Digital Living Network Alliance network. Media content may be stored by accessing the media server or by downloading the media content to the media server. Support of set top boxes interacting with voice-on-demand (VOD) controllers and computers interacting with IP-based video content servers are integrated through the media server. Consequently, VOD assets can be played on IP-based devices and IP-based content can be played on set top boxes. A gateway function converts IP-based content to a VOD asset, and renders the VOD asset to a set top box while mapping digital rights management information for the VOD asset. Conversely, the gateway function may convert a VOD asset to IP-based content that can be played on an IP-based device.

Then, an image compositing section 18 generates the composite image by stitching the reference image and the target image together based on the boundary determined by the boundary determining section 16.

Finally, an image stitching operation can be selected based on a likelihood that a particular image stitching operation will produce visible artifacts. Once a stitching operation is selected, the images corresponding to the overlap region can be stitched using the stitching operation, and the stitched image can be stored for subsequent access.
