Abstract: Implementations described herein utilize redundancy information for packet data portions. For instance, a first packet includes multiple data portions. A second packet is generated that includes redundancy information for one or more of the multiple data portions of the first packet. In at least some implementations, the redundancy information can be used to determine whether an error condition occurs related to the first packet, such as data errors and/or a dropped data portion.

Abstract: There is provided an apparatus comprising at least one processor; and a memory comprising code that, when executed on the at least one processor, causes the apparatus to: attempt to receive a first packet comprising multiple sub-payloads having an order from first to last; receive a second packet comprising multiple sub-payloads having an order from first to last, wherein the first sub-payload in the second packet comprises redundancy information for the last sub-payload in the first packet and the second sub-payload in the second packet comprises redundancy information for a sub-payload other than the last sub-payload in the first packet; and use the redundancy information to determine information in relation to the first packet.

Abstract: Disclosed herein is a technique whereby a user device joins a call conducted over a network, generates audio which can be processed to identify that user device and, during the call, outputs the audio such that it can be received by another user device in the vicinity of the user device which is already participating in the call, thereby enabling the other user device to identify that user device.
