借這幾個推文問一下
我本來是一直很好奇HDMI隨介面數量收授權金這件事
都說因為這樣所以顯卡大部分都做HDMI*1+DP*3
但是現在大部分螢幕都給HDMI*2+DP*1
我想說是不是輸出端跟輸入端的授權金算法不一樣
但我找HDMI授權金的文章基本上都跟這篇一樣

依這篇文章來看
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.
這是說授權金是看產品數量跟晶片、HDMI介面或HDMI線的數量無關吧
我真的不懂了
