This disclosure describes a video interconnect system that may establish a Video over Long Term Evolution (ViLTE) communication session between two interacting client devices. In some examples, the video interconnect system may selectively establish a ViLTE communication based on one or more rules associated with the domain information of interacting client devices, availability of network bandwidth, bandwidth consumption of a video component of the ViLTE communication, or established service agreements between telecommunication service providers of the interacting client devices. Further, the video interconnect system may facilitate generating termination charges for a video and/or audio communication session of a ViLTE communication. For example, a video component of the ViLTE communication may be charged and metered based on data usage, and an audio component of the ViLTE communication may be charged and metered based on the duration and relative location of the interacting client devices.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a feedback configuration for reporting feedback for transport blocks encoded with at least two encoding schemes and may receive a transport block comprising a plurality of code block groups (CBGs). A first subset of CBGs of the plurality of CBGs may be encoded using a first encoding scheme and a second subset of code block groups of the plurality of CBGs may be encoded using a second encoding scheme different from the first encoding scheme. The UE may transmit, according to the feedback configuration, a first feedback report for the first subset of CBGs corresponding to the first encoding scheme and a second feedback report for the second subset of CBGs corresponding to the second encoding scheme based on determining whether each of the plurality of CBGs of the transport block are decoded.

A scheme for optimizing segment sizes for an adaptive bitrate (ABR) streaming client engaged in a current ABR streaming session. In one implementation, a determination is made whether a wireless UE device executing the ABR streaming client is approaching a radio white spot area. If so, a video buffer of the ABR client is configured to preload a fixed number of segments having an adjusted size depending on the duration of the radio white spot area. The preloaded segments may comprise lower quality video segments, and as the wireless UE device exits the radio white spot area, the segment size and/or bitrates may be restored depending on the signal quality.

Aspects relate to techniques for MCS selection of a packet to be network coded for sidelink communication. A transmitting UE may encode a packet using an MCS that is greater than a normal MCS that may be used for encoding the packet without network coding. The transmitting UE may then transmit the encoded packet to one or more receiving UEs and a network coding device over a sidelink data channel. The transmitting UE may further transmit a network coding request flag associated with the packet to initiate one or more retransmissions of the packet by the network coding device.

A communication apparatus includes circuitry to: obtain, before transmission of video data to a counterpart communication apparatus via a network, communication environment information to be used for determining magnitude of variation of communication quality of the counterpart communication apparatus; determine, using the obtained communication environment information, a coding setting of the video data in accordance with the magnitude of variation of the communication quality of the counterpart communication apparatus; and code the video data in accordance with the determined coding setting; and a transmitter to transmit the coded video data to the counterpart communication apparatus via the network.

A method is provided for processing an error during restitution of digital content during a multimedia session on a terminal. The session offers a plurality of representations of the digital content which are described in a medium carrying information describing the multimedia session and transmitted independently of the representation data. The method includes, following the obtaining of the description-carrying medium, acts of obtaining, for at least one representation indicated in the description information-carrying medium, at least one item of information regarding guarantee of availability of the data of the representation on a server; of comparing the information regarding guarantee of availability of the data of the representation on the server with at least one predetermined value; of selecting a fallback representation as a function of the result of the comparison, and upon detecting a restitution error, of toggling to the fallback representation selected.

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.
