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 and apparatus for providing a messaging server within a premises device e.g., a home or enterprise gateway device. In one embodiment, a system is described that includes a premises device that acts as a centralized client messaging platform providing messaging services between a content provider and client devices, and also between client devices within a premises network. The premises device enables client-to-client communication that bypasses the long trip and propagation delay over the Internet by connecting the message across the premises network within the home or building. The premises device enables messages to be communicated between a content provider outside the premises network and the client devices via a single connection to minimize the number of Internet connections that need to be opened, and the number of messages communicated with servers outside of the premises network via both upstream aggregation and downstream dis-aggregation, which collectively save both network bandwidth and device reaction time.

摘要: Apparatus and methods for recording a media stream for use by a rendering device. In one embodiment, a client device records live, unbound streaming media content from a Content Delivery Network (CDN) in “chunks” according to a data structure such as a manifest file. The live media content stream chunks are compressed and stored for later playback. The client device uses information regarding the chunks to generate a local manifest file, which it then uses to reconstruct the media stream. A video client may also dynamically insert and account for updated secondary content (such as advertisements) during each playback instance, thus enabling the service provider to realize commercial opportunities which were previously not possible. Various operational/business rules are also disclosed for e.g., enabling and disabling functions with respect to playback of the content.

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: Apparatus and methods for presentation of key frames. In one embodiment, an encoded video file is generated where one or more bits are assigned to key frames and minimizes the number of bits assigned to delta frames. Each key frame may be presented to a user during trick mode operation (e.g., fast forward, rewind, pause, or random seek operation). When the encoded video file is given to a packager, the packager generates a manifest file listing the byte information (byte offset and number of bytes) for each key frame in the encoded video file. When a user inputs a trick play mode command, the packager provides the manifest file to the client device of the user and the client device requests the bytes for the key frames of the video file from the content delivery network.

摘要: Methods and apparatus for providing a supervisor such as a parent or guardian with a way to monitor and control the delivery of content, e.g., video and audio programs, to users of devices within a home. Exemplary embodiments include methods and apparatus for operating a home network monitoring device located in a home including detecting delivery of content to one or more users in the home, storing, in the home, portions of content delivered to a first user, presenting some of the stored portions of content to a person responsible for setting content restrictions applicable to the first user, and subjecting further content delivery to the first user via the home network to restrictions established by the person responsible for setting content restrictions applicable to the first user. Some embodiments also detect and report potential attacks, e.g., cyber attacks, on the home network.
