摘要： Methods and apparatus for providing enhanced catalog data capacity and functionality within a content distribution network. In one embodiment, the apparatus includes an architecture configured to utilize an upstream out-of-band (OOB) channel for upstream catalog data request carriage, while a downstream in-band (IB) QAM is used for carriage of the catalog data issued by the network in response to the request. In another embodiment, the extant catalog structure is largely retained, yet modified so as to (i) eliminate redundancy within “barker” channel audio/video data delivery, and (ii) reduce the encoding resolution of the barker audio and/or video so as to utilize less bandwidth, thereby allowing enhanced capacity for catalog title expansion (and/or reduced latency in responding to catalog requests).

摘要： 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.

摘要： Methods, systems and devices are provided for communicating multimedia content over a service provider network. A network server may receive an audio-video stream from a content provider server, relaying the audio-video stream to a receiver device via the service provider network, receive an operating mode notification identifying a user behavior from the receiver device, and ceasing the relaying of the audio-video stream to the receiver device based on the user behavior. The network server may also alter the audio-video stream based on the received operating mode notification and send the altered audio-video stream to the receiver device via the service provider network.

摘要： A playlist server application is provided on a server at a first network node. A playlist local application is provided for a remote device. An indication of a change to a playlist on one of the server and the remote device is obtained from a corresponding one of the playlist server application and the playlist local application. The change is synchronized to another one of the server and the remote device.

摘要： Methods and apparatus that facilitate providing alternative content to customer devices in systems supporting DASH streaming are described. Various features relate to dynamically modifying and providing media presentation description (MPD) information to customer devices. MPD information is used by customer devices to obtain media content, e.g., program content and/or alternative content. The client device, e.g., a IP content playback device, switches between a mode used during playing of program segments in which an in-band EMSG is used to trigger a request for an MPD update and a mode of operation used during the playing of additional or alternative content segments during which the client device will periodically request MPD information. By limiting requests for MPD information during normal program segments to requests triggered by an EMSG the number of update requests can be minimized or reduced as compared to other approaches where requests for updated MPD information are made periodically.
