The Motorola NC1500 is a Hybrid Fiber Coax (HFC) Network Controller that enables interactive applications with Motorola’s DCT2000 terminals. The NC1500 enables interactive sessions between application servers and the DCTs by translating Internet Protocols (IP) to deliver data packets through the out-of-band data channel. The return path serves as the upstream data path where the NC1500 aggregates demodulated data bursts and routes the data to the appropriate server.
The Motorola SmartStream interactive digital cable system consists of an integrated set of high performance stream-processing elements necessary for the successful deployment of advanced services like VOD and digital ad insertion.
The Motorola ARPD (Advanced RPD) is a next-generation headend product that offers greater demodulator density in a more compact chassis than the currently fielded RPD-2000 product. The Motorola ARPD is a modular 1 RU product that supports the
inclusion of up to six removable (hot-swappable) demodulator modules (ADM-4000 modules). The Motorola ARPD performs the same functions as the RPD-2000 product, but offers a larger number of upstream demodulators in a smaller physical package. In addition to saving rack space, the ARPD easily and efficiently allows multiple upstream demodulators to be placed in each upstream path. This increases the bandwidth capacity of each upstream return path, allowing the system to support increased VOD penetration and the introduction of new interactive features such as switched digital video.
Motorola DAC6000 RADD
The Motorola (DAC6000) Digital Addressable Controller consists of several advanced components that provide the latest in security and control for flexible digital systems. With an easy-to-use, menu-driven system, the Motorola DAC provides support for a wide variety of addressable control functions including IPPV, Call Ahead PPV, subscriptions and interactive applications.
The Motorola OM 2000 Out-of-Band Multiplexer/Modulator generates an out-of-band (OOB) data stream from the headend to digital cable set-top devices, either individually or on a broadcast basis. The Motorola OM 2000 can be configured to receive data over Ethernet using UDP/IP, or as serial data over RS-530 or RS-232 communications links. The OOB data stream is used primarily as a signaling channel, but is also used to transmit electronic program guide (EPG) information and code download data. The out-of-band data stream is also the downstream path in an interactive system.
The Motorola OLL1000 (Offline Loader) is a specialized carousel server that provides the capability to rapidly load numerous code objects on various set-top box types in a warehouse environment or other staging area independent of the production system. The OLL1000 uses broadcast functions to clear stale code and/or configure mixed set-top types, so that no individual set-top addressing/configuration is required.The OLL1000 provides the warehouse with more control over code suites. It does so by keeping the loading independent, which has the added benefit of pre-loading set-tops in anticipation of planned code upgrades to support field installations on the day of the code upgrade. It is possible to create the code assignments for the new code a day or two in advance, providing the warehouse with more control over the code suites being pre-loaded.As shown in the figure below, the OLL1000 system consists of an OLL server, an OM1000/2000, and a population of set-tops. The OLL provides a canned OOB transport stream, necessary configuration messages, code download control messages, and a DCII-compliant code download object carousel to allow a set-top or host to download the desired suite of code objects for a particular warehouse or region.
The Motorola RPD2000 (Return Path Demodulator) is an essential component of a local access network configuration. It provides the upstream link that is needed for communications
with set-top terminals. The Motorola RPD2000 terminals provide essential information such as Aloha interactive data, pay-per-view (PPV) purchases as well as critical
status monitoring data. Data is received by burst demodulator modules within the Motorola RPD2000. The unit can be equipped with up to six modules,
The Motorola out-of-band multiplexer/ modulator, OM-1000, provides an out-of-band data stream to the digital settop terminals. The Motorola OM 1000 is primarily used as a signaling channel but can also provide for transmission of program guide information, code downloads, InfraRed codes, as well as application information. It is also utilized as the downstream path in an interactive system.
The Motorola NE1000 (Network Encryptor) supports the centralized encryption of MPEG services in a MediaCipher® conditional access system . The Motorola NE1000 also provides the ability to support efficient Single Program Transport Stream (SPTS) distribution of
services, which is necessary in Switched Digital Video (SDV) applications. Support for centralized encryption in VOD systems can also be supported. The NE supports both full encryption (unique tier per service) and Common Tier Encryption (CTE), where each encrypted service shares the same access requirements. The NE can be configured to follow the input copy control information within an input DTCP descriptor, as well as to follow settings provided by the DAC or made by the operator directly on the NE EM (CTE only).
