Various aspects include methods for supporting Enhancement for Television (ENTV) service delivery to a user equipment (UE) in a fifth generation new radio (5G-NR) radio access network (RAN). Various aspects may include generating an ENTV capability message, the ENTV capability message indicating one or more ENTV parameters of the UE, and sending the ENTV capability message to a Next Generation NodeB (gNB) of the 5G-NR RAN. Various aspects may include receiving a ENTV capability message from the UE, the ENTV capability message indicating one or more ENTV parameters of the UE, determining one or more radio resource configurations for the UE based at least in part on the one or more ENTV parameters of the UE, and generating a configuration message indicating the one or more radio resource configurations for the UE, and sending the configuration message to the UE.

Systems and methods adapted for providing heterogeneous media services in communication systems, such as using transport layer security deferral and/or medium redirect, are disclosed. In operation according to embodiments, heterogeneous media services may be facilitated by obtaining, by a hybrid broadcast receiver of a receiver device, a computer parsable object comprising information regarding content segment availability and access, wherein the hybrid broadcast receiver is adapted to obtain content via both broadcast and broadband connections for a streaming client of the receiver device. The hybrid broadcast receiver of embodiments may further operate to evaluate the computer parsable object for one or more content segment entries indicating transport layer security is to be invoked with respect to a connection used for obtaining one or more content segments and to overwrite the one or more content segment entries preventing the transport layer security from being invoked by the streaming client.

A split streaming system and method are provided in which a stream of data (that can be video, audio or textual data) is split and sent over a plurality of stream reflectors to a stream recipient. Each stream reflector performs time gradient replacement to manage the split streaming.

A content protection system for satellite-based content delivery is provided, including a satellite content receiver. The satellite content receiver may include one or more processors and a non-transitory processor readable medium, and be in communication with a satellite antenna. The satellite content receiver may receive a first portion of streaming media content, transmitted by a content security host system using multicast communication. The first portion of the streaming media content may be stored, and later accessed in response to a user command. A second portion of the streaming media content including data missing from the first portion of the streaming media content may be identified. The second portion may be requested from the content security host system and received by the satellite content receiver. The first and second portions of the streaming media content may be combined to reconstruct the streaming media content, which may then be output.

This application provides a multicast service transmission method and apparatus, to deliver a multicast service regardless of whether there is a device supporting multicast in a system, so as to improve flexibility and reliability of the multicast service transmission. The method performed by a session management network element includes: receiving a first message or a second message, where the first message requests to add a terminal device to a multicast service, the second message is used to update a PDU session of the terminal device, and the PDU session is associated with the multicast service; and determining, based on multicast capability information of the terminal device and/or multicast capability information of an access network device, a delivery mode of the multicast service, where the access network device is an access network device currently accessed by the terminal device or a target access network device of the terminal device.

A system and method for managing multicast streams. For example, one embodiment of a system comprises: a distributed caching system including at least one cache at an edge of a live content provider network, the live content provider to generate a live video stream to be cached and/or buffered within the distributed caching system; an agent to request multicast services from a packet-based network, the packet based network to establish a multicast channel at a location, the location including a plurality of wireless access points; and manifest processing logic associated with the agent to generate an updated manifest from an original manifest associated with the live video stream, the updated manifest to include an indication of the multicast channel, wherein a plurality of video player apps executed on user devices at the location are to interpret the indication of the multicast channel in the manifest to connect to the multicast channel, the plurality of video player apps to simultaneously receive and render the live video stream, or a transformed version thereof, over the multicast channel.

The system and methods described aid content delivery by providing requested content using a hybrid delivery of unicast and multicast content. A content delivery system receives, from user equipment, a request for content and identifies multicast sources for the content. The content delivery system determines a recent multicast source from the multicast sources, the recent multicast source having begun more recently relative to the other sources. The content delivery system transmits, to the user equipment, an identity of the recent multicast source and provides a beginning portion of the content to the user equipment via a unicast stream.
