    Abstract: The present disclosure provides an apparatus and method for encoding a video with ultra-low latency, the apparatus including: one or a plurality of video sources configured to provide a video signal; an encoder configured to encode the video signal provided through the video source and provided for each of the video sources; and a caster configured to transmit video data encoded by the encoder to the outside through a network communication network.
    Accordingly, the present disclosure can transmit a video with ultra-low latency, so a video service is possible in real time anytime anywhere as long as the internet is connected, whereby there is the advantage that the present disclosure can be applied to various fields of 4th industry such as autonomous driving, unmanned drone operation, driving of unmanned heavy equipment, robot control, a remote medical service, VR/AR, an intelligent CCTV, a smart city⋅factory, provision of traffic information, etc.

    Abstract: In an embodiment, a head mounted device (HMD) is configured to receive streamed virtual reality or augmented reality (VR/AR) data through a first connection and a second connection. The streamed VR/AR data is controlled by a controller that transmits first streamed VR/AR data from a data source to the HMD via the first connection and transmits second streamed VR/AR data from the data source to the HMD via the second connection such that the HMD receives a continuous stream of VR/AR data when the data source switches from transmitting the first streamed VR/AR data to transmitting the second streamed VR/AR data.

    Abstract: The system trains a machine learning model using a loss function, with a part that penalizes overall signal loss, and a second part of the loss function that penalizes texture loss. The system computes a first neural feature of a first media frame stored by a media server using the trained machine learning model. The system causes a client device to receive a second media frame as a part of a media stream from the media server where the second frame is a modified version of the first media frame. The system causes the client to compute a second neural feature of the second media frame using the trained machine learning model, and compute a QoE metric based on the first neural feature and the second neural feature. The system receives the QoE metric, and uses it to modify at least one parameter of the media stream.

    Abstract: A method for controlling transmission of a media stream service includes: receiving, from a network node in a data network, policy template information for controlling transmission of media stream services and service differentiators corresponding to the policy template information; determining a service differentiator of a to-be-initiated media stream service based on the policy template information and the service differentiators; determining whether a protocol data unit session capable of carrying the to-be-initiated media stream service exists; binding the to-be-initiated media stream service to the quality of service stream in the protocol data unit session in response to a determination that the protocol data unit session exists; and establishing, in response to a determination that the protocol data unit session does not exist, a protocol data unit session including the quality of service stream corresponding to the service differentiator of the to-be-initiated media stream service.

    Abstract: A method and processing unit for creating and rendering synchronized content for content rendering environment are described in present disclosure. Initially, live content rendered to users in content rendering environment is received. Further, inputs from first user, and optionally from one or more second users is collected during rendering of live content. The inputs comprises user inputs provided in at least one of virtual environment and user actions in real-world environment. Inputs are collected along with at least one of corresponding time stamp and corresponding spatial stamp in content rendering environment. Upon collecting inputs, live content is synchronized with the inputs based on at least one of the time and spatial stamp, and context mapping of the inputs with segments of the live content to output a synchronized content. By rendering such synchronized content to the user, replication of live rendering of the content may be experienced by the user.
