Abstract: A content selector switch selects, based on a received request for content from a particular remote control device, a multicast network on which to provide the requested particular content. Each multicast network channel of the plurality of multicast network channels is mapped to a respective video channel and each remote control device in the facility (e.g., hotel) is mapped to a respective video channel that the TV controlled by the remote control device stays tuned to. The content selector switch performs the selection by identifying which remote control device in the facility sent the request and selecting the multicast network channel that is mapped to the RF video channel the identified remote control device is mapped to. The content selector switch then provides the specific content on the selected multicast network channel to a multicast-to-channel output device that provides the content on the RF video channel for the TV tuned to that RF video channel to display.

Abstract: 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.

Abstract: The present disclosure provides systems and methods for customized programming through “virtual zoning”, not based on network architecture or geographic region, via a modified electronic programming guide (EPG) provided to devices assigned to virtual zones. Broadcasters may thus provide virtual zone-based “localized” programming to devices regardless of location. The virtual zone-based EPG may be functionally identical to conventional EPGs, and thus fully compatible with existing recipient devices, without requiring custom programming or manufacturer resources. Content may be broadcast to virtual zones via multicast IP streams, with primary content provided to a plurality of virtual zones and custom content provided on a stream-by-stream basis. The resulting system is highly scalable, requiring additional resources only based on the number of virtual zones (which may be numbered in the tens or hundreds, in many implementations) rather than the number of recipient devices (which may be numbered in the millions).

Abstract: The described technology is generally directed towards a surf mode of operation for streaming content such as video content, in which different content is arranged as different channels though which a user can surf by changing the streaming channels. The starting times of the different content can be staggered. Aspects comprise streaming first content corresponding to a first interactively selectable streaming channel to an output device, receiving a change request to change to a second interactively selectable streaming channel, and in response to the receiving the change request, streaming second content corresponding to the second interactively selectable streaming channel to the output device.

Abstract: Methods and apparatus for providing delivery of content to client devices of a network via both multicast and unicast mechanisms. In one embodiment, a system for use in a managed content delivery network is described to bridge multicast to unicast, so that the total network bandwidth consumption is significantly lower than a corresponding unicast-only delivery solution, yet which still provides improved quality of service and user viewing experience as compared to a multicast-only delivery solution. In addition, various exemplary aspects of the present disclosure are readily adapted for real-time multicast to unicast streaming of audio and data to, among other things, minimize network bandwidth usage, while maintaining the guaranteed delivery of unicast streams with little or no modification to the existing client device logic.

Abstract: A media server is hosted in a service provider's network so that media content can be stored from or rendered to a private network such as a Digital Living Network Alliance network. Media content may be stored by accessing the media server or by downloading the media content to the media server. Support of set top boxes interacting with voice-on-demand (VOD) controllers and computers interacting with IP-based video content servers are integrated through the media server. Consequently, VOD assets can be played on IP-based devices and IP-based content can be played on set top boxes. A gateway function converts IP-based content to a VOD asset, and renders the VOD asset to a set top box while mapping digital rights management information for the VOD asset. Conversely, the gateway function may convert a VOD asset to IP-based content that can be played on an IP-based device.

Abstract: An audio-visual live content delivery system includes a client having access to a provider network via a gateway, an audio-visual live content delivering equipment comprising a multicaster for transmitting audio-visual live contents in multicast form via the provider network, a de-multicaster being able to perform a conversion in unicast form of audio-visual live contents received in multicast form from the multicaster, and a controller managing routing of requests to get audio-visual live contents. The client performs a discovery procedure aiming at receiving information on potential presence and availability of the de-multicaster. When the client intends receiving a targeted audio-visual live content, the client sends to the controller a request providing indication of presence and availability, or not, of the de-multicaster. Then the controller decides how redirecting the client to fulfill the request, according at least to the indication of presence and availability, or not, of the de-multicaster.

Abstract: Systems, apparatuses, and methods are described for monitoring data transmitted and/or received via multicast transmission and, based on latency, segment loss, and/or other occurrence, modifying sources and/or other characteristics of additional data transmission. The data may be video segments of media content items. Sources of video segments can be changed based on comparisons of rates of arrival of video segments, failure to receive segments, etc. Selection of an encoded version of content for multicast and/or unicast transmission may be based on indications of delay and/or non-receipt, and/or based on predictions of increased load on a network.
