So, whether you have an NTSC/PAL TV or the latest HDMI Flat Panel, we have you covered.

At this level, encrypted keys are stored and provisioned by a Conditional Access Server (CAS) located at the local Service Provider’s site. The process works like this:• Periodically, the STB establishes contact with the CAS.• An Authentication/Authorization (a/a) negotiation process takes place.• If the CAS determines that the user a/a is good, it delivers an encrypted key to the STB. This allows the STB access to whatever services have been assigned to that user.• If the user a/a is bad, the STB is instructed to turn itself off.• If the STB cannot establish contact with the CAS within a 10 day period, it will turn itself off.• At this point every time the STB is turned on it will look for the CAS and try an a/a negotia- tion. If it cannot find the CAS and receive a valid a/a within a 15 minute time period it will turn itself off.

Ringtail Service Type 1: Hardware & Software for Broadband Service Providers

Ringtail Service Type 2: Hardware, Software & Broadband Service Provider

Combining a Desktop PC, conventional TV, and Internet connection provides the end-user with a powerful platform for educational use. Ringtail STB serves not only as a Media Center, it serves as a powerful Education Access Point (EAP) as well. Service Providers, in cooperation with regional Educational Authorities, can easily establish eClassroom programs. These programs can provide valuable educational opportunities to users located in remote and/or inaccessible locations. Targeted at under-served and developing nation needs, the EAP platform is a unique concept. Ringtail is committed to the development, promotion, and deployment of EAP opportunities. We are the �rst and only technology provider to o�er the EAP platform. Please contact us to discuss this exciting new development.
