Abstract:

Digital data associated with recorded programs are uploaded to a Head End facility from user devices (e.g., set-top boxes) in a media distribution network. The Head End facility stores a library of the Digital Video Recording (DVR) assets for programs and makes them available, by streaming, to user devices, including user devices that do not have DVR capability. Techniques are also provided to efficiently upload a DVR asset simultaneously in segments or chunks from multiple user devices.

H04W 68/00

US Classification:

4554121, 4554142

Abstract:

Media content communication may be provided. First, an incoming communication may be received at a subscriber device. A determination whether multimedia content is associated with the incoming communication may then be made. The multimedia content may be associated with, for example, a caller, and may be played back as a video tone indicating a communication originating from the caller. The multimedia content may also be delivered with the incoming communication, retrieved by the subscriber device, and played back upon acceptance of the incoming communication or stored for later retrieval upon denial of the incoming communication.

International Classification:

H04L 12/66

US Classification:

370254

Abstract:

An apparatus can include a connection manager adapter that is configured to maintain presence for each of the plurality of non-IP endpoints in an IP messaging and presence protocol based on the endpoint presence data. The endpoint presence data includes a unique identifier and attribute data received for each of a plurality of non-internet protocol (IP) endpoints. The connection manager adapter can be configured to access the endpoint presence data and convert a message between the IP messaging and presence protocol and different protocol for communication with a given non-IP endpoint of the plurality of endpoints.

Abstract:

In one embodiment, a method and system for a companion device to share an application context and authorization context with a consumer premises equipment (CPE) device is described. The method and system includes transmitting a search request by a search request transmitter using a service discovery protocol, receiving a response to the search request from the CPE device, creating an authorization context at an authorization context creating processor, the authorization context including metadata that grants access to a resource, transmitting, by an authorization context transmitter, the authorization context to an application resident on the CPE device, establishing a trusted session between the application resident on the CPE and a device application, the establishing a session by the device application including requesting a digital certificate from the CPE, receiving the digital certificate from the CPE, and validating the digital certificate, creating, at an application context data creating processor, application context data, and transmitting the application context data created to the CPE device, wherein the application context data enables the CPE device to request access to an authorized resource from a resource provider. Related methods, systems, and apparatus are also described.
