General Instrument was an electronics manufacturer based in Horsham, Pennsylvania specializing in semiconductors and cable television equipment. The company was active until 1997, when it split into General Semiconductor which was later acquired by Vishay Intertechnology in 2001, CommScope and NextLevel Systems .The new General Instrument Corporation was acquired by Motorola in January 2000 and became the new Broadband Communication Sector along with an acquisition of Zenith Network Systems a few months later. After being called Connected Home Solutions, it was renamed Home and Networks Mobility in 2007. When Motorola split on January 4, 2011, this division became part of Motorola Mobility. On December 19, 2012, ARRIS announced that it would acquire Motorola Mobility's Home unit from Google for $2.35 billion in cash and stock. The acquisition was completed on April 17, 2013.Moses Shapiro, father of former Monsanto head Robert B. Shapiro, was Chairman from 1969 to 1975. Frank G. Hickey served as chief executive officer from 1975 to 1990, as did Donald Rumsfeld from 1990 to 1993. The acquisition was completed on April 17, 2013. Wikipedia.

A sampling filter process is provided for scalable video coding. The process provides for re-sampling using video data obtained from an encoder or decoder process of a base layer (BL) in a multi-layer system using adaptive phase shifting to improve quality. Examples of a multi-layer encoder or decoder process are MPEG-4 Advanced Video Coding (AVC) and High Efficiency Video Coding (HEVC). The re-sampled BL data can be used in encoding or decoding of a corresponding video data of higher layers in a scalable video coding system. For example, the re-sampled or upsampled data can be used as a basis for prediction of the higher resolution video data.


Combining network and client based adaptive streaming approaches enable a distributed and adaptive resource management system for carrier quality video transmission over cable Wi-Fi systems. The adaptive resource management over cable Wi-Fi heterogeneous networks includes a network based approach using client based feedback. The resource management of a video stream is performed on a service providers network, for example in a cable modem termination system, by evaluating a margin and a fairness index. In embodiments, the rate of a video stream to a requesting client is adjusted and, in embodiments, the rate of a video stream for non-requesting clients is adjusted. Embodiments include mechanisms for call admission control and adaptive streaming based on adjustable resource margins and fairness indices for DOCSIS and Wi-Fi hetnet systems.

Buffer bloat continues to cause latency problems for all kinds of network traffic, e.g., internet protocol traffic. Implementing network based control of packet upstream packet discards enables a scheduler of packets to manage congestion, instead of the network element with bloat. In embodiments, a cable modem termination system may schedule delivery of packets and, after receiving the scheduled packets, discarding packets. The cable modem termination system may determine when to discard a packet based on a detected backlog of data in a cable modem upstream flow queue. For example, a late discard of such packets may be based on information in a schedule request received from the network element.


A constrained variable rate coding technique limits the number of bits used in an encoding process. A quality setting indicates a maximum level of quality to be used in the encoding process which limits the number of bits used in the encoding process. A bandwidth reclamation factor which indicates an amount of bandwidth to conserve may also be used with the quality setting. The constrained variable rate coding technique using a lower quality encoding process for less complex video data and a higher quality encoding technique for higher quality video data.


A method and system are provided for securely storing and retrieving live off-disk media programs. Events delineate media segments, each of which are encrypted with a different key so as to be streamable to a remote device via digital living network alliance (DLNA) or HTTP live streaming protocols. Media segments and identifiers for managing the storage and retrieval of such media segments are compatible with live streaming data structures, obviating the need to re-encrypt data streams.
