  • Programmable integrated DiSEqC transceiver
    Patent number: 7336706
    Abstract: Programmable integrated Digital Satellite Equipment Control (DiSEqC) transceiver. The DiSEqC functionality is integrated onto a semiconductor device. Rather than perform the DiSEqC protocol in software, the DiSEqC protocol is implemented in hardware thereby providing more reliable demodulation and improved robustness. The device's functionality may employ much more reliable communication schemes that are enabled by the hardware/integrated approach of implementing the DiSEqC protocol. The integrated approach allows extensive programmability of the various operational parameters thereby greatly improving the ease of future backward compatibility with legacy devices; devices employing this integrated DiSEqC functionality may be easily updated to conform to future enhancements of the DiSEqC protocol.
