Media feed prioritization for multi-party conferencing
Techniques presented herein provide an improved relay user experience and improved management of scarce computing and network resources as the number of relay endpoints increases. A sourcing endpoint device may generate a media feed, such as video and/or audio feed, representing contribution from a conference participant. The sourcing endpoint device may generate a priority value for the media feed, and the priority value may be transmitted to other members of the relay along with the input feed. Priority values of the different relay participants may be used by other devices, for example, intermediate servers or receiving endpoint devices, to manage aspects of the relay. For example, a relay server may prune streams from select endpoint devices based on relative priority values received from those devices. Alternatively, receiving endpoint devices may alter presentation of received feeds based on their associated priority values.

RADIO FREQUENCY CONDITION AWARE AUDIO BUFFERING
An example method includes receiving, by a communication controller of a source device and from an audio source of the source device, audio data to be wirelessly transmitted to a sink device, wherein the audio data is received from the audio source at a rate; storing, by the communication controller and in a buffer, the audio data as a sequence of audio blocks, wherein each audio block includes audio data for a respective output time; transmitting, by the source device and to the sink device, audio blocks of the sequence of audio blocks using a wireless link between the source device and the sink device; determining a current condition of the wireless link; and automatically adjusting, by the communication controller and based on the current condition of the wireless link, the rate at which audio data is received from the audio source.
METHOD AND APPARATUS FOR ESTABLISHING BLUETOOTH DATA CHANNEL
A method and an apparatus for establishing a Bluetooth data channel are provided. In the method, before starting a service in a first mode, a first communications apparatus negotiates with a second communications apparatus to determine a first parameter. The first parameter may be used for establishing a data channel between the first communications apparatus and the second communications apparatus. After starting the service in the first mode, the first communications apparatus sends a first message to the second communications apparatus. The first message is used to request the second communications apparatus to establish the data channel based on the first parameter. According to the foregoing method, before starting the service in the first mode, the first communications apparatus negotiates with the second communications apparatus to determine the first parameter.
Transport protocol for anticipatory content
Methods, apparatuses, and systems for improving utilization of a communications system (e.g., a satellite communications system) are provided, using delayed reliability techniques as part of a multicast transport protocol. Embodiments may operate in a client-server context, in which the server-side of the communication link multicasts data to requesting users and to users where the data is being speculatively prepositioned. Requesting users may implement reliability checks to verify receipt of complete data in response to the request while user systems where data is being speculatively prepositioned may receive multicast reliability information in response to reliability requests from other users, but may not request replacement of missing or corrupted data themselves until a request is made for the data by that system.

Real-time screen sharing
In implementations of the subject matter described herein, there are provided a method and apparatus for real time screen sharing. During the screen sharing of two devices, if a certain condition is satisfied for an image encoded by a first device and an image decoded by a second device, the first device pauses image processing images. If the pause time of pausing satisfies a certain length, a parameter associated with an image compression ratio is adjusted. After the first device resumes image processing, the adjusted parameter is used to encode a new image captured on the first device. According to implementations of the subject matter described herein, a transmission code rate during the screen sharing can be controlled according to the pause time of pausing image processing. The implementations of the subject matter described herein can reduce transmission latency of screen sharing, thereby effectively ensuring the user experience.
METHODS FOR MEDIA STREAMING CONTENT PREPARATION FOR AN APPLICATION PROVIDER IN 5G NETWORKS
A method of directing content preparation for a 5G media streaming (5GMS) network performed by at least one processor implementing a 5GMS application provider, the method comprising creating a content preparation template, by the 5GMS application provider, wherein the content preparation template includes first information specifying instructions for content preparation, and second information specifying instructions for content output; establishing a first provisioning session with a 5GMS application function; transmitting the content preparation template to the 5GMS application function in the first provisioning session, wherein the 5GMS application function requests to allocate 5GMS content preparation resources and 5GMS content distribution resources; and receiving a first acknowledgement from the 5GMS application function, wherein the first acknowledgement indicates an allocation of at least one of content preparation resources and content distribution resources.

Method and system for live video streaming with integrated encoding and transmission semantics
This disclosure relates generally to method and system for live video streaming with integrated encoding and transmission semantics. The system receives a set of frames associated with a live video stream encoded to generate a set of data fragments using a reference encoder and a delta encoder. Transmitter unit of the live video streaming protocol transmits each packet of the set of full frames and the set of delta frames in sequence with a payload specific header based on a packet mode. Further, the receiver unit receives each packet of the full frames and each packet of the delta frames based on the packet mode to reconstruct an original sequence from the foreground pixels by estimating a total number of packets expected at each frame interval and loss incurred in each packet of the set of full frames and the set of delta frames.
