Assignee:

General Instrument Corporation - Horsham PA

International Classification:

H04N 7/12

H04B 1/66

US Classification:

37524007

Abstract:

Method and apparatus for encoding video is described. In one example, average of motion vectors for each of a plurality of blocks is maintained over a threshold number of inter-coded frames in the video. The running average of motion vectors for each of the plurality of blocks is compared to a threshold value. Each of the plurality of blocks the running average of which does not satisfy the threshold value is encoded using a first quantization parameter. Each of the plurality of blocks the running average of which satisfies the threshold value is encoded using a second quantization parameter. The second quantization parameter results in a coarser quantization of transformed coefficients than the first quantization parameter.

Abstract:

An apparatus, method and system for delivering Internet Protocol (IP) content within a system that includes a bypass architecture, using a Session Encapsulation Information Database (SEIDB). Within an existing PacketCable Multimedia (PCMM) framework used as a control plane for IP content bypass flow setup, the SEIDB system stores session bypass encapsulation information for IP content bypass flows within the system. Within the SEIDB, each entry of bypass encapsulation information has a flow classifier component that uniquely identifies a bypass flow in a manner that allows both a cable modem termination system (CMTS) and the IP content source to uniquely identify the bypass flow at the SEIDB. Initially, the CMTS gathers bypass encapsulation information and uploads it to the SEIDB. Before the bypass flow begins, the IP content source obtains the necessary bypass encapsulation information from the SEIDB, e. g.

International Classification:

H04J 3/22

US Classification:

370465, 370252

Abstract:

A communication system is provided that ensures that a rich variety and complexity of network offerings may be experienced by users without overloading terminals and clients by offering user-centric network services. When a user device first registers with a network, the user device notifies the network of its client capabilities, such as video, VoIP, presence, and so on. Based on the client capabilities and further based on any user preferences, the network then announces, that is, offers to the user, a list of available services for the user to choose from. Network services and applications then may be downloaded and used only when the services and applications are needed or desired by users, thereby allowing a thin middleware layer and network customization.

International Classification:

H04L 12/66

US Classification:

370352

Abstract:

An apparatus, method and system for delivering Internet content within a system that includes a bypass architecture, such as a bypass architecture that transmits content from the Internet or an Internet content source to a downstream modulator, such as an Edge Quadrature Amplitude Modulation (EQAM) modulator, in a manner that bypasses the system's Cable Modem Termination System (CMTS). Content from the Internet or an Internet source is transmitted to a last-hop router, which is configured to identify content for bypass encapsulation. The last-hop router also can be configured to perform at least a portion of the necessary bypass encapsulation for proper bypass flows of the identified content. Alternatively, the EQAM is configured to perform the bypass encapsulation, and the last-hop router transmits the identified content to the EQAM, which performs at least a portion of the necessary bypass encapsulation on the identified content.

International Classification:

H04N 7/173

US Classification:

725110

Abstract:

An apparatus, method and system for delivering Internet content within a system that includes an encapsulation database and a last-hop router as part of a bypass architecture, such as a bypass architecture that transmits IP content from a source to a downstream modulator, such as an EQAM modulator, in a manner that bypasses the system's Cable Modem Termination System (CMTS). The encapsulation database, which typically is controlled by the MSO, but also is in operable communication with the last-hop router and CMTS, is configured to store encapsulation identification information, which is used to identify which portions of the IP content receive bypass encapsulation. The encapsulation database also can include the QoS settings for such identified portions of IP content. The encapsulation database allows the MSO to provide QoS settings for select portions of IP content, such as videos from internet video providers with whom the MSO has made special arrangements.

US Classification:

455435

Abstract:

A plurality of secondary stations (10. sub. a through 10. sub. n) are coupled to a primary station (8) by way of a shared communication medium (15, 16). The secondary stations (10. sub. a through 10. sub. n) sends information to the primary channel on the upstream channel. The primary station sending information to the secondary stations (10. sub. a through 10. sub. n) on a downstream channel. The power level of a secondary station (10. sub. n) is set at the power level stored in secondary station memory (55). The secondary station (10. sub. n) transmits a message to the primary station on the upstream channel. The primary station (8) receives the message, determines the power level of the received message, and sets the power level of the secondary device to the nominal power level.

US Classification:

248127

Abstract:

A support base made of bamboo culms is provided. Culms forming legs for support are cut to form a flat surface on the ends of culms contacting a floor. Holes are drilled through the culms at selected distances and angles so as to allow the culms to form a support having a waist. The structure is supported by wires, cord, rope or similar members through the holes that are placed in tension when a load is applied to the base. Spacers, preferably of bamboo culms having a smaller diameter than the legs, are placed over the wires between legs of the base.
