  • Out-of-home transmissions for digital video recorder
    Patent number: 10863226
    Abstract: Devices and methods are provided for out-of-home transmissions for digital video recorders. The device may receive, at a first port of the device, a first packet from a second device using a peer-to-peer (P2P) connection between the device and a second device, first packet including a first session identifier associated with a first socket based on the first port and a second port of the second device. The device may receive a second packet from the second device using the P2P connection, the second packet including a second session identifier. The device may determine a second socket based on the second session identifier, the second socket based on the first port and a third port of the second device. The device may send a third packet using the second socket, the third packet including the second session identifier.

  • Camera-level image processing
    Patent number: 10580149
    Abstract: Devices, systems and methods are disclosed for performing image processing at a camera-level. For example, a camera service may run on top of a camera hardware abstraction layer (HAL) and may be configured to perform image processing such as applying a blurring algorithm, applying a color filter and/or other video effects. An application may pass metadata to the camera service via an application programming interface (API) and the camera service may use the metadata to determine parameters for the image processing. The camera service may apply the blurring algorithm for a first period of time before transitioning to unblurred image data over a second period of time.
