A method for determining an initial bitrate for a communication includes receiving a communication request to establish a digital communication between a first user device and a second user device associated with a plurality of features including a geographical identifier identifying a geographical location associated with the first user device, a first network type connection associated with the first user device, a second network type connection associated with the second user device, and an average bitrate for a previous digital communication of the first user device. The method includes determining, using an initial bitrate predictor model configured to receive the plurality of features as feature inputs, an initial bitrate for the digital communication between the first user device and the second user device, and establishing the digital communication between the first user device and the second user device at the determined initial bitrate.

A method performed by a user equipment (UE) wirelessly connected to a wireless communication network for facilitating transmission of a real-time media flow from a sender towards the UE is described. The method includes sending a request to the network, requesting a packet loss prediction and a throughput prediction for transmission of a real-time media flow from the network towards the UE. The method also includes receiving, from the network, information of a predicted UE throughput and a predicted UE packet loss predicted by the network in response to the sent request. In some embodiments, the method also includes sending the received information to a sender of the real-time media flow to the UE.

A pixel value of a pixel in a picture of a video sequence is modified by a weighted combination of the pixel value and at least one spatially neighboring pixel value in a filtering. The filtering depends on a pixel distance between the pixel and a neighboring pixel and on a pixel value difference between the pixel and a neighboring pixel value of the neighboring pixel. The filtering is controlled by a spatial parameter and a range parameter. At least one of the spatial parameter and the range parameter depends on at least one of a quantization parameter, a quantization scaling matrix, a transform width, a transform height, a picture width, a picture height and a magnitude of a negative filter coefficient used as part of inter/intra prediction. The embodiments provide a deringing filtering to combat ringing artifacts during video coding.

Deringing filter for video coding

A pixel value of a pixel in a picture of a video sequence is modified by a weighted combination of the pixel value and at least one spatially neighboring pixel value in a filtering. The filtering depends on a pixel distance between the pixel and a neighboring pixel and on a pixel value difference between the pixel and a neighboring pixel value of the neighboring pixel. The filtering is controlled by a spatial parameter and a range parameter. The spatial parameter depends on at least one of a width and a height of a transform block, and on at least one of a prediction type of a block of pixels in the picture, a picture type of the picture, and a slice type of a slice in the picture.

Disclosed is a method performed by a system of a wireless communication network for determining transmission conditions for a real-time media flow to be transmitted wirelessly to a first User Equipment, UE, residing in a first cell served by a first base station of the network. The method comprises obtaining radio network statistics of the first cell, the radio network statistics comprising radio network data for individual of a plurality of UEs in the first cell, UE throughput for individual of the plurality of UEs, and UE packet loss or packet delay for individual of the plurality of UEs, and obtaining, at a second time point occurring later in time than the obtaining of the radio network statistics, radio network data for the first UE. The method further comprises determining a predicted first UE throughput and a predicted first UE packet loss or packet delay based on the obtained radio network statistics of the first cell and on the obtained radio network data for the first UE, and triggering sending of information of the predicted first UE throughput and of the predicted first UE packet loss or excessive packet delay to a sender of the real-time media flow to the first UE. A Forward Error Correction, FEC, optimization module takes the predicted UE packet loss rate, the predicted UE throughput, and adapts the amount of FEC redundancy packets according to the throughput and packet loss rate. Further, the adapted amount of FEC redundancy packets are then used by the sender of the video when transmitting the video.

Systems and methods for providing third-party content can include a data processing system receiving a first content selection parameter and a plurality of second content selection parameters to manage serving of content items of a third-party content provider. The data processing system can store the first content selection parameter and a plurality of second content selection parameters in a memory bank. Upon receiving a request for third-party content, the data processing system can retrieve the first content selection parameter and the plurality of second content selection parameters from the memory bank, and determine a parameter among the first content selection parameter and the plurality of second content selection parameters. The data processing system can select a content item from a plurality of content items of the third-party content provider based on the determined parameter, and provide the selected content item for presentation on a client device.

Systems and methods for arranging and storing content selection parameters based on selection policies

Chunks () of encoded video data of a streamed video bitstream () are stored and encoded video data is decoded to form decoded video data to be output for display. A selected portion () of the stored chunks () or selected sub-chunks () of the stored chunks () for a previous, already played out part () of the streamed video bitstream () is or are discarded while keeping selected stored chunks () or selected sub-chunks () stored as navigation tune-in points. The usage of selected stored chunks () or sub-chunks () that are not discarded from the already played out part () of the streamed video bitstream () enables a low delay solution during video navigation when a user wants to jump to a previously played out position () within the streamed video bitstream ().

The invention relates to an encoder and a decoder and methods therein for supporting screen sharing, where the screen sharing comprises encoding pictures F representing pixels of a shared screen, providing said pictures to a decoder where they are decoded. The method performed by the encoder comprises deriving information related to an object which is moved on the shared screen between two pictures Fand F. At least part of the derived information is related to an intermediate position of the object, on the shared screen, between the two pictures Fand F. The method further comprises providing said information to the decoder, thereby enabling the decoder to generate intermediate pictures, F, in addition to the pictures, F, based on the provided information, wherein the object is generated in different positions in said intermediate pictures, F, thus reconstructing the movement of the object between two provided pictures Fand F.

A system and method of the subject technology automatically constructs a database instruction from a template instruction, including one or more variable tokens, and one or more document object representations, each including an object type and a user-generated parameter. The one or more variable tokens in the template instruction are substituted by the user-generated parameter of a corresponding document object representation when the type of a respective variable token is matched to the type of the corresponding document object representation.

In a data packet router, a router fabric card for routing data packets is provided. The router fabric card comprises a plurality of ingress/egress ports, the ports connected through a switching facility for switching connection states of the port paths between individual ingress paths and individual egress paths on the fabric card, and a scheduling component for scheduling communication between ports on the fabric card. Data coming into ingress on the card is organized into individual data-packet trains, each individual train comprising data packets and inserted data denoting a starting point and an ending point of a train. The switching facility recognizes the start data and the end data of a train and switches port paths to a next-assigned connection state accordingly.
