Abstract: An example device for decoding media data includes a memory configured to store the media data and one or more processors implemented in circuitry and communicatively coupled to the memory. The one or more processors are configured to determine whether two or more decoder instances are intended to be synchronized. The one or more processors are configured to, based on the two or more decoder instances being intended to be synchronized, control the two or more decoder instances so as to enable rendering of decoded data from each of the two or more decoder instances at a same presentation time.

Abstract: Various embodiments may include methods and systems for improving Quality of Service (QoS) in an end-to-end network connection including a first communication network and a second communication network. A method may include determining, by a network element within the end-to-end network connection, a QoS requirement of the end-to-end network connection, obtaining, by the network element, QoS information of the second communication network from a reporting entity within the second communication network, and adjusting, by the network element, a QoS parameter of the first communication network based on the determined QoS requirement and the obtained QoS information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a multicast-broadcast user service description message. The UE may communicate, using a multicast-broadcast service (MBS) transport function (MBSTF) client, with an MBS entity of the network entity, in accordance with information included in the user service description message, wherein the MBS entity is split into a multicast delivery function and a unicast application server. Numerous other aspects are described.

Abstract: In embodiments of systems and methods for synchronous content presentation, an Edge server device may receive a decryption key for an encrypted content segment that is or will be delivered to a plurality of wireless devices over the wireless communication network, and may send the decryption key to the plurality of wireless devices after the encrypted content segment has been received by the plurality of wireless devices in a manner that enables the plurality of wireless devices to decrypt the encrypted content segment approximately simultaneously. A wireless device may receive, and optionally temporarily store, the encrypted content segment from the wireless communication network, receive the decryption key from the Edge server device after receiving the encrypted content segment, and decrypt the stored encrypted content segment using the received decryption key.
