StarGuide® II and III Service Modules
The StarGuide® II and III receivers each contain ports which can be populated with StarGuide Service Modules. These modules are specially designed, low cost, plug-in modules that can be used to provide any combination of audio, video, and data services simultaneously. Current Service Modules include:

	eDAS™ (Ethernet Enabled Digital Audio Storage) Module A revolutionary "store-and-forward" advance that brings the power and flexibility of the Transportal 2000™ delivery system into the receiver. This card allows a "live" audio feed to be automatically mixed locally with pre-encoded audio clips or "spots". The spots are sent via satellite through the Transportal 2000™ delivery and scheduling system to the eDAS™ Module in a StarGuide® Receiver. Since each eDAS™ Module is uniquely addressed a spot can either be sent to a single eDAS™ Module or a group of eDAS™ Modules, allowing networks to regionalize or even localize targeted advertisements, liners, or short form programming. The eDAS™ Module can currently store up to 2 ½ hours of 128kbps encoded audio and is capable of being upgraded to 5 hours. Files encoded at 64, 96, 192, and 256 kbps are also supported. Content delivery is confirmed over the Internet through the integrated 10/100BT interface or an external modem. In addition, the content of the Module can be "browsed" from any personal computer via a built-in web site capability on the Module.
	10Based-T Ethernet Interface Module A unique data module that allows receivers to bolt directly up to a 10BT LAN essentially creating a WAN via satellite. The StarGuide® 10BT Ethernet Interface module receives IP data via satellite and routes it to an external LAN. The Module supports both multicasting and individually addressed IP packets. For multicasted data, the Module acts like a multicast router supporting IGMPv2. The Module can be remotely monitored via telnet and SNMP.
	10/100Based-T Ethernet Interface Module An enhanced Ethernet module that supports both 10BT and 100BT LAN's. This Module supports all of the features of the 10BT Ethernet Interface module but enhances the Ethernet interface so that it auto-negotiates between 10BT and 100BT networks.
	Musicam® MPEG Layer II Digital Audio Decoder Module A high quality Musicam® Audio Decoder Module designed for broadcast applications. This Decoder Module provides 20kHz of CD-quality balanced audio as well as four relay contact closures and an asynchronous data stream. This Module is ideal for the radio broadcast industry. The decoder will automatically adjust to the encoded data rate and mode (mono/stereo/joint stereo).
	Relay Expansion Module An additional automation tool to be used in conjunction with the Musicam® Decoder Module. When a broadcaster needs more than four relays embedded in a audio stream for automation purposes, the Relay Expansion Module provides up to 16 relay contact closures. Since the relay contact closure information is embedded in the digitized audio stream, the relationship between the audio and the relay contact closure is preserved.
	MPEG2 Digital Video Decoder Module An MPEG2 video decoder that delivers a single channel of digital video including the associated audio. The MPEG2 Digital Decoder supports both NTSC and PAL outputs while the audio decoder supports mono, stereo, and joint stereo output modes. The MPEG2 Digital Video Decoder module automatically detects the settings of the encoded video stream generated at the head-end.

StarGuide® Transportal 2000™ Multimedia Delivery Service
A comprehensive store and forward delivery service that utilizes both terrestrial and satellite components for electronic media delivery. The Transportal 2000™ Delivery System combines the best features of satellite, Internet, point-to-point terrestrial connection, and traditional dub-and-ship methods to produce a state of the art media delivery system that is economical, reliable, and fast. This System includes packaging, tracking, and confirmation that can be accessed either locally or remotely via the Internet.

StarGuide® DVB™ Multiplexer
A high capacity DVB multiplexer supporting up to 40 audio channels and 20 external transport streams multiplexed into a single DVB output stream. Multiplexers can be cascaded to produce DVB streams with a high number of services. The StarGuide DVB Multiplexer consists of up to 20 integrated Musicam® Audio Encoding cards and a Starguide® MPEG-DVB Sub-Multiplexer Card. Each Encoder card can encode 2 stereo analog audio feeds while the Sub-Multiplexer Card controls and aggregates the data within the chassis. The StarGuide Multiplexer is controlled through a 10BaseT interface with either telnet or SNMP.
