摘要： A compression system trains a machine-learned compression model that includes components for an encoder and decoder. In one embodiment, the compression model is trained to receive parameter information on how a target frame should be encoded with respect to one or more encoding parameters, and encodes the target frame according to the respective values of the encoding parameters for the target frame. In particular, the encoder of the compression model includes at least an encoding system configured to encode a target frame and generate compressed code that can be transmitted by, for example, a sender system to a receiver system. The decoder of the compression model includes a decoding system trained in conjunction with the encoding system. The decoding system is configured to receive the compressed code for the target frame and reconstruct the target frame for the receiver system.

摘要： Systems and methods are provided for using a Multiple Depth Plane (MDP) prediction in predictive coding. The system detects a camera viewpoint change between a current frame and a previous frame, decomposes a reconstructed depth map of the previous frame to a plurality of depth planes, adjusts the plurality of depth planes from a previous camera viewpoint to correspond with a current camera viewpoint, generates an MDP prediction by summing pixel values of the adjusted plurality of depth planes along a plurality of optical axes from the current camera viewpoint, determines an MDP prediction error between the MDP prediction and a depth map of the current frame, quantizes and codes the MDP prediction error, and transmits, to a receiver over a communication network, the camera viewpoint change and the coded quantized MDP prediction error for reconstruction of a depth map of the current frame.

摘要： An interleaved multi-layered video data stream with interleaved decoding units of different layers is provided with further timing control information in addition to the timing control information reflecting the interleaved decoding unit arrangement. The additional timing control information pertains to either a fallback position according to which all decoding units of an access unit are treated at the decoded buffer access unit-wise, or a fallback position according to which an intermediate procedure is used: the interleaving of the DUs of different layers is reversed according to the additionally sent timing control information, thereby enabling a DU-wise treatment at the decoder's buffer, however, with no interleaving of decoding units relating to different layers. Both fallback positions may be present concurrently. Various advantageous embodiments and alternatives are the subject of the various claims attached herewith.

摘要： Systems and methods for encoding a video stream at multiple bit rates is disclosed herein. An encoder divides each frame of a video stream into a plurality of portions and allocates an available number of bits between the plurality of portions based on user preference information. Portions having one or more objects of interest to the viewer determined based on the user preference information are allocated a higher number of available bits while portions of the frames that do not include one or more objects of interest are allocated a minimum number of bits from the available bits.

摘要： The disclosure is related to adaptive transcoding of video streams from a camera. A camera system includes a camera and a base station connected to each other in a first communication network, which can be a wireless network. When a user requests to view a video from the camera, the base station obtains a video stream from the camera, transcodes the video stream, based on one or more input parameters, to generate a transcoded video stream, and transmits the transcoded video stream to a user device. The base station can transcode the video stream locally, e.g., within the base station, or in a cloud network based on transcoding location factors. Further, the camera system can also determine whether to stream the video to the user directly from the base station or from the cloud network based on streaming location factors.

摘要： A network management system manages the operation of a home security system in a communication network, such as a mesh network. The home security system can include multiple components such as a camera, a lighting device, a security alarm, a doorbell switch and doorbell chime, and a fingerprint sensor, which connect with the communication network to perform various operations. The network management system monitors environmental parameters of the communication network, such as parameters associated with the access points and components of the home security system, determines an access point to which a component of the home security system is to be connected for efficient operation of the home security system, and connects the component to the communication network via the determined access point.

摘要： A device, system and method for intelligently dropping frames in a congested wireless network. Video frames from a video encoder may be received and queued in an ordered sequence of outgoing video frames in a transmission queue to be transmitted as data packets by a wireless communication circuit. When network congestion is detected, a relative contextual importance level of an incoming frame received from the video input channel may be compared relative to at least one frame in the transmission queue. The compared frame that has a lower relative contextual importance level may be dropped or omitted from the transmission queue, thereby transmitting data packets of the frames in the transmission queue without the dropped or omitted frames.

摘要： A method and system are provided for streaming a video game from a server to a client. One example system includes the server configured to generate video frames for the video game responsive to input received from the client. An encoder that processes the video frames to generate compressed video frames and storing past encoder states in memory associated with the encoder. The server is configured to transmit the compressed video frames to the client. The server is configured to receive a feedback signal from the client to determine when one or more of the compressed video frames that were sent were not been received by the client. The encoder is configured to generate one or more next video frames as compressed video frames that are dependent on compressed video frames that are known to have been successfully received based on the feedback signal.
