Abstract

Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for a first wearable device and a second wearable device to initiate media sessions with a user equipment (UE) and an end device. The wearable devices may each initiate a session flow by transmitting session description protocol (SDP) offer messages to the end device. In some examples, the wearable devices may transmit capability information to the UE, and the UE may transmit an SDP offer message to the end device. The end device may begin the session after receiving the one or more SDP offer messages by transmitting one or more SDP answer messages. The wearable devices may each transmit information about a user of the wearable devices. The end device may generate streams of media content, and the UE may cast the streams of media content to the wearable devices.

transmit a first version of media content via a first stream of the media content to the first contact lens via the first real-time transport protocol session, wherein the first version comprises a baseline version including a first rendered video; and

transmit a second version of media content via a second stream of the media content to the second contact lens via the second real-time transport protocol session in coordination with the first stream of media content, wherein the second version comprises the baseline version including the first rendered video and a differential version that includes a delta between the first rendered video and a second rendered video that is associated with the second stream of the media content, wherein the baseline version is groupcast to the first contact lens and the second contact lens and the differential version is unicast to the second contact lens.

5 . The apparatus of claim 4 , wherein the instructions are further executable by the at least one processor to cause the apparatus to:

transmit, to the end device, a set of aggregated information that comprises the first set of information associated with the user and the second set of information associated with the user; and

receive, from the end device, aggregated media content associated with the first stream of media content and the second stream of media content.

6 . The apparatus of claim 4 , wherein the instructions are further executable by the at least one processor to cause the apparatus to:

receive, from the end device, an indication of the baseline version and the differential version.

7 . The apparatus of claim 4 , wherein the instructions are further executable by the at least one processor to cause the apparatus to:
