Methods, systems, and devices for wireless communication are described. A user equipment (UE) may dynamically indicate a resolution change to a display of the UE during a video call. For example, a first UE may communicate a configuration message with a second UE to establish a video call between the first UE and the second UE and indicate a first value for a resolution of a display of the first UE. During the video call, the first UE may identify a change to the resolution of the display and may transmit a message to the second UE that indicates the change to the resolution. In response to receiving the message, the second UE may encode one or more packets including video information for the video call according to a second value for the resolution and transmit the one or more packets to the first UE.

A computer-implemented method for preserving media streams may include (i) identifying a media stream transmitted by a client device to a server that hosts the media stream for access by additional devices, (ii) detecting that the server is expected to go offline, (iii) sending, in response to detecting that the server is expected to go offline, a message to the client device indicating that the server is expected to go offline, (iv) receiving, at an additional server, a request from the client device to host the media stream, and (v) in response to receiving the request, hosting the media stream at the additional server while ceasing to host the media stream at the server that is expected to go offline. Various other methods, systems, and computer-readable media are also disclosed.

Provided is an information processing device capable of operating in accessibility mode of guaranteeing browsing corresponding to disability or functional degeneration of a body of an operator. A source device checks whether each sink device is in accessibility mode at the time of connection, and determines whether or not metadata for supporting disability (for example, audios, videos, texts, vibration information, or the like) is added to the sink device in the accessibility mode at the time of transmission of original image/audio data. The source device changes a metadata transmission method in accordance with whether the accessibility mode of each sink device is turned on or off.

The present invention relates to a digital broadcasting system for transmitting/receiving a digital broadcasting signal and a method of processing data. In one aspect of the present invention provides a method of processing data, the method including receiving a broadcasting signal in which mobile service data and main service data are multiplexed, demodulating the received broadcasting signal, obtaining an identifier indicating that data frame of the broadcasting signal includes service guide information, decoding and storing the service guide information from the data frame; and outputting a service included in the mobile service data according to the decoded service guide information.

Technology for a first multimedia telephony services over internet protocol (IP) multimedia subsystems (IMS) (MTSI) client operable to support region of interest (ROI) signaling with a second MTSI client is disclosed. The first MTSI client can identify a requested region of interest (ROI). The first MTSI client can encode the requested ROI for transmission to the second MTSI client via a real-time transport control protocol (RTCP) feedback message. The first MTSI client can decode encoded video received from the second MTSI client that corresponds to the requested ROI.

A user equipment, media control unit, media resource function, or another device or function capable of receiving, manipulating, and transmitting data may be configured to: receive an omnidirectional video; determine a viewport of a user equipment; determining a delivery mode; determine a region of the omnidirectional video based, at least partially, on the determined viewport and the determined delivery mode; encode the determined region; packetizing the encoded region; and transmit the packetized region to the user equipment based, at least partially, on the determined delivery mode.

The disclosure relates to a 5th Generation (5G) or 6th Generation (6G) communication system for supporting a higher data transmission rate. The method of a first entity performing a media resource function (MRF) includes transmitting, to a second entity, a session description protocol (SDP) offer message for an SDP negotiation associated with a conference providing a plurality of 360-degree videos, and receiving, from the second entity, an SDP answer message. Wherein the SDP offer message includes a plurality of media descriptions for the plurality of 360-degree videos, and wherein, in case that a first 360-degree video of the plurality of 360-degree videos is originated from one of a plurality of sources at a conference location of the conference, a first media description for the first 360-degree video includes a content attribute for identifying a source from which the first 360-degree video is originated.
