Combined Multimedia - Devices are becoming moore an moore popular. They do provide various usage possibilities like:
Typical examples are the Siemens-Fujitsu Multitainer and the Activy300, which are based on Intel PC architecture. Also other devices like the popular dbox2 can be rebuilt to a multimedia terminal. After Linux installation on the dbox2, it is possible to use the dbox2 for the above mentioned multimedia - tasks.
The Linux Projekt is available under GPL and open source. The complete Linux CDK for developement is available at http://www.tuxbox.org. A good website concerning the usage of smartcards under Linux is M.U.S.C.L.E. (Movement for the use of Smart Cards in a Linux Environment) http://www.linuxnet.com/smartcard/software.html
The smartcard in multimedia - devices can also be used for:
As the multimedia-devices do combine several devices with various application possibility, it may be necessary to use moore then one smartcard at the same time. Herefore we did develope the SC8in1 interface - it enables the connection and control of up to 8 smartcard units on devices, which do posses a serial port.
The SC8in1 interface is distributed without sofware. As delivered and without using drivers, the SC8in1 Interface is Smartmouse / Phoenix compatible. In such a case, the first inserted smartcard will be used. With additional control through the serial port, it is possible to recognize in which smartcard - units, smartcards are present and to select a desired card. The control of SC8in1 can be performed with code in "C" as shown in this example, using Windows or Linux. When switching from one to another smartcard, the power supply, the reset-line and the clock are not interrupted and reinitialization of the separate cards is not necessary. Each of the 8 smartcard units posses its own oscilator, so unlimited combinations of oscilators are possible.
The SC8in1 interface can be built in internal into a Nokia dbox2, Philips dbox2 or Sagem dbox2
Inside a Nokia dbox2 it is possible to integrate in total 6 smartcard - units. The number of smartcard units, which can be in total built in a Sagem dbox2 or Philips dbox2 is two. As the SC8in1 interface is capable to control up to 8 smartcard units, the rest number of smartcard units can be integrated in a external housing and connected to the SC8in1 interface.
Alternatively, the SC8in1 interface can also be used outside the housing of the device, using a extension cord and be placed together with up to 8 smartcard - units in a external housing.
Using a RS232 TTL converter, the SC8in1 interface can be connected to any device, which does posses a serial port. The required 5V voltage can usually be taken from the device.
Due to the variaty of possible combinations, the SC8in1 interface is offered as follows:
