New HUGE ECM in the works. -------------------------------------------------------------------------------- Bev and Charlie are increasing the length of CMD07. At the moment,BEV has increased the length of the CMD07 packet to 104 bytes (from the previous 72). The extra bytes are not doing anything at the moment, but you can bet they will do something very soon. Charlie seems to be taking a different approach: He injects the longer CMD07 once in a while and removes it. Most likely some kind of testing going on. Regardless, major changes are coming soon. A few possibilities: 1. They may be moving to 768bit RSA on the CMD07 from the previous 512bit. If so, Atmegas should finally be gone. The decryption timeswill be too damn tight - and x-15 had given them highly optimized code to begin with. As for Enigma, I can easily double-up the speed in hardware and got tonnes of space for more optimized 768-bit RSA. I don't know how many FTAs can survive the new speed requirements. You see, the Enigma has 15 seconds to compute the control words - but it doesn't do anything else. Whereas, an FTA unit has to multitask and keep the screen live and not crash while calculating the control words. My guess is that the higher end models @300MHz will survice. Low-endmodels like Pansat2500 running at 90MHz won't make it. CEMU should survive too if using a PC greater than 300MHz. Armulator should make it. 2. The other aspect of this is the fact that the extra payload data in CMD07 will surely be used in the new decryption algorithm of CMD1C. Ifthis happens, and a secret key is chosen from IRD firmware, only Echostar IRDs should continue to function. That should nail the coffin shut on FTA. This ECM will be HUGE. end C/P |

感谢大家的帮助,已经看上卫星啦!!
虽然最后没有自己安装,但是各位的帮助还是非常有用的。 来帮我安装卫星的James我也推荐一下,工作非常认真细致,Nice job! 和邻居安装的卫星一比,就看出大大的差别了! 我现在可以看到121和110两个星,一个 viewstat ultra 接收机。信号质量都是 70%以上。 我有一个问题问大家,请知道的专家回答。 James告诉我,如果要看两台电视,需要两个接收机,这个我理解,而且线必须从LNB下来两根。 我的问题是在市场上难到就没有这样一种产品,把一个线分为两根的switch么?我理解因为频率和其他因素的关系,可能比较难,但是总会有公司开发这样的产品把? 请不吝赐教。 |
