Abstract:

Methods and apparatus for providing unified access to interactive media applications and services in a network. In one embodiment, the network comprises a content-based network such as a cable television or satellite network, and the applications are disposed at the network headend. A servlet is provided to facilitate communication between the applications and client devices. The servlet acts as a proxy for applications utilizing a different content format than the client devices. The applications obtain data from e. g. , an internet host server via a gateway device. The client application(s) may comprise Enhanced TV Binary Interchange Format (EBIF) pages, and are configured so as to permit use via a common interface (e. g. , the user's set top box and television display). These client applications enable a user to, for example, search the internet for data relating to displayed content, post and navigate micro-blogs, instant messaging or SMS, making telephone calls (e. g.

International Classification:

H04N 7/173

US Classification:

725114, 725131

Abstract:

A video content system includes a server module, a video content network coupled to the server module, and a digital set-top terminal coupled to the video content network. The digital set-top terminal in turn includes a processor; an interface coupled to the processor and the video content network; and a memory module. The memory module has at least a partitioned hard disk with a first partition containing digital video programming received over the video content network, and a second partition containing supplemental resources.

International Classification:

H04N 21/643
H04N 21/462

US Classification:

725 54, 725110

Abstract:

Techniques disclosed herein include systems and methods for transmitting TV program related content to IP connected devices on a home network, or other local area network. Users can watch television while simultaneously receiving content related to TV programs currently being displayed on a television. TV centric and TV program related content can be transmitted to IP connected devices. Moreover, this TV program related content can be displayed at the same time as a television program is being displayed on a television. As such, the system can provide media synchronization within home network using the set-top box as a gateway for delivering the content. Users can watch TV at home, and at the same time receive TV program related content on a laptop, tablet computer, mobile phone, etc.

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 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.

Abstract:

Techniques disclosed herein enable automated home security monitoring via a television connected to a set-top box, such as a cable set-top box. Such techniques integrate the television with a home security system. A television viewer can use the television to control, interact, and automatically receive information about home security events in real-time. A television viewer can control lighting, and room temperature, and arm/disarm sensors in the home such as door sensors, motion detectors, cameras, etc, as well as access camera images. Events from such sensors can be monitored or viewed on the television set when they are triggered. For example, when triggered, an icon representing the sensor can be shown on the television screen, or in case of a camera, an image or video can be shown that cause the triggered event.
