Abstract: Methods and systems are described for providing complete Internet anywhere with partial server processing in which a request is sent from a set-top-box (STB) to a server communicatively coupled with the STB to process a portion of a web page that is unsupported by a web browser running on the STB. In one such method, the STB sends to the server an unsupported content request associated with a portion of a web page that is unsupported by a web browser executing on the STB. The STB receives a data stream from the server in response to the unsupported content request. The data stream was generated at the server by processing the unsupported portion of the web page. The STB composites the received data stream with another portion of the web page, that is supported by the web browser, to produce the web page.

Abstract: A processor for a cable television set-top box has an interface for coupling the processor to a second processor. The processor also has a port that is coupleable to control a tuner, a demodulator and a DOCSIS module with or without DSG support. The tuner has an output coupled to the demodulator input, and the demodulator has an output to the DOCSIS module input. The demodulator's output is also coupled to a conditional access module controlled by the second processor. The processor issues commands via the port to control at least one of the tuner and the demodulator based on instructions received via the interface from the second processor.

Abstract: A set top box or like device incorporating an untrusted software framework as a client of a secure operating system kernel. The software framework may comprise, for example, an Android framework supported by an underlying Linux operating system environment having a secure kernel. The software framework can be executed using a variety of process isolation techniques depending on performance and isolation requirements. A secure access client/server interface may also be provided to support interactions between the untrusted software framework (and applications utilizing the untrusted software framework) and secure or trusted portions of the device. The secure access interface can be configured to perform operations such as handle validation, heap pointer validation, non-pointer parameter validation, heap isolation, and resource release relating to terminated processes. In further embodiments, a software framework aggregator is used to support a plurality of additional software frameworks for use in the set top box.

Abstract: A gateway having at least one communications interface and processing circuitry establishes communications with at least one service provider device and at least one serviced client device. The gateway then determines that a serviced client device is to establish an Internet browsing session. Based upon characteristics of the serviced client device, the gateway determines where to instantiate a web browser to service the Internet browsing session. Based upon the determination, in a first operation, instantiates the web browser to service the Internet browsing session at the gateway or client device. In a second operation, the gateway instantiates the web browser to service the Internet browsing session at a service provider server. In other operations, the gateway may determine to instantiate a browser for a first client device at a cloud server and to instantiate a browser for a second client device either locally or at the second client device.

Abstract: Disclosed are various embodiments that facilitate fast switching of synchronized media using time-stamp management. A first media stream and multiple second media streams are obtained. The second media stream is time synchronized to the first media stream. The first media stream and one of the second media streams are decoded. Time-stamp management without decoding is performed for another one of the second media streams to facilitate fast switching to the other one of the second media streams when desired.
