借这几个推文问一下
我本来是一直很好奇HDMI随接口数量收授权金这件事
都说因为这样所以显卡大部分都做HDMI*1+DP*3
但是现在大部分萤幕都给HDMI*2+DP*1
我想说是不是输出端跟输入端的授权金算法不一样
但我找HDMI授权金的文章基本上都跟这篇一样

依这篇文章来看
The royalty fee structure is the same for all volumes. The following variable pe
r-unit royalty is device-based and not dependent on number of ports, chips or co
nnectors:
US$0.15 for each end-user licensed product.
US$0.05 – If the HDMI logo is used on the product and promotional material, the
per-unit fee drops from US$0.15 to US$0.05. Use of HDMI logo requires complianc
e testing.
US$0.04 – If HDCP is implemented and HDMI logo is used, the per-unit fee drops
further from US$0.05 to US$0.04.
这是说授权金是看产品数量跟芯片、HDMI接口或HDMI线的数量无关吧
我真的不懂了
