Abstract: A method for partially unmasking an object in a video stream comprises: displaying a first video stream in which objects are covered by privacy masks; receiving user input regarding a selection of an object being covered by a privacy mask, wherein the object has a first portion being associated with a first privacy level and a second portion being associated with a second, higher, privacy level; checking that a permission associated with the user input grants access to video data depicting object portions being associated with the first privacy level; giving access to video data depicting the first portion of the object; and displaying a second video stream which differs from the first video stream in that it includes the video data depicting the first portion of the object, while the second portion of the object is still covered by a privacy mask.

Abstract: A signed media bitstream comprises data units and signature units. Each signature unit is associated with one or more nearby data units and include at least one fingerprint derived from the associated data units and a digital signature of the at least one fingerprint. A storing method comprises: receiving a segment of the media bitstream; identifying N?2 instances of a repeating data unit in the received segment; pruning up to N?1 of the identified instances of the repeating data unit; and storing the received segment after pruning. A validation method comprises: receiving a segment of the media bitstream stored in accordance with the storing method; and validating a signature unit using a digital signature contained therein. Despite the pruning of the repeating data unit, the received associated data units can be successfully validated, either directly or indirectly, by means of different embodiments herein.

Abstract: A method and device for communicating video for synchronization between a portable wearable camera and a wireless hub device are described. The portable wearable camera may capture first video data. Also, the portable wearable camera may transmit the first video data to the wireless hub device via a video data channel, and may capture second video data. When the video data channel between the wearable camera and the wireless hub device is unable to support full resolution video playback, the portable wearable camera may store the second video data. Further, the portable wearable camera may receive a request via a control channel, from the wireless hub device, for the second video data, and may capture third video data. Further, the portable wearable camera may transmit, to the wireless hub device, the third video data via the video data channel and the second video data via the control channel.

Abstract: Methods for configuring a monitoring device to communicate with a service server are provided. The method includes the monitoring device sending a message including a monitoring device identifier used by a control server to identify the service server associated with the monitoring device, receiving one or more service server addresses associated with the identified service sever from the control server, and establishing a service connection between the monitoring device and the identified service server using the one or more addresses received from the control server. A control server adapted to configure a monitoring device in a monitoring system and a method for configuring the control server are also provided.

Abstract: A surveillance camera system includes a power sourcing equipment corresponding to a midspan having one or more of integrated input/output (I/O) and audio port functionality, the power sourcing equipment including processing circuitry, one or more data ports, one or more of an I/O port and an audio port, and a Power over Ethernet (PoE) port. Additionally, the surveillance camera system includes a camera connected to the power sourcing equipment by the PoE port, and a computer connected to the power sourcing equipment by one of the data ports, wherein the computer is configured to receive data from and transmit data to the camera via the power sourcing equipment.

Abstract: An image processing device, a non-transitory computer-readable storage medium and a method for dividing an array of pixels into slices and tiles, and a system for encoding the slices and tiles into a video stream by means of a first encoder arranged in a first image processing circuitry and a second encoder arranged in a second image processing circuitry are disclosed. The array of pixels consists of a first subset of pixels having pixel data stored in a first buffer arranged in the first image processing circuitry and a second subset of pixels having pixel data stored in a second buffer arranged in the second image processing circuitry, wherein a first border between the first subset of pixels and the second subset of pixels is tilted at a tilt angle in relation to the array of pixels. The array of pixels is divided into two or more slices, and each slice is divided into two or more tiles.

Abstract: A method and image processing device for encoding a video comprising a sequence of image frames captured between a first and a second time is disclosed. The method comprises encoding a subset of the image frames, wherein the image frames of the subset are distributed over the sequence and storing the remaining image frames of the sequence. After the second time, the encoded subset is decoded and the stored remaining image frames as well as the decoded encoded subset are encoded to generate the encoded video. Alternatively, the stored remaining image frames are encoded and the encoded subset added to generate the encoded video.

Abstract: Apparatus, systems and techniques are provided associated with a battery powered wireless camera, which includes an internal battery and an image capture module to capture images. Further, the battery powered wireless camera may include a first communication module and a second communication module configured for wireless communication. If the second communication module is powered down, the image capture module may store captured infrared images. If activation is triggered, the second communication module may power up and wirelessly transmit the captured images. In an example, the wireless camera may further include an infrared detection module configured for capturing infrared images. Further, the activation may include any one of a noise, a motion, a timing, a command, and an infrared detection. Also, the first communication module may wirelessly communicate utilizing a first communication mode and the second communication module may wirelessly communicate utilizing a second communication mode.

Abstract: Systems (300; 400), a non-transitory computer-readable storage medium (330; 430), and methods (100; 200) for managing metadata associated with an object detected in an image, wherein the object corresponds to an area of the image are disclosed. A metadata item associated with the object is obtained, wherein the metadata item comprises an identification of the area, and a quantitative level of an image data characteristic of the area or of the area as encoded is determined. A condition in relation to the determined quantitative level of the image data characteristic is evaluated, and on condition that the condition is fulfilled, reducing or discarding the metadata item. In alternative, a level of compression of the area as encoded is determined, and it is determined if the level of compression is higher than a compression threshold. On condition that the level of compression is higher than the compression threshold, the metadata item is reduced or discarded.
