問題描述

客戶反饋TX50導入支持4K的license文件成功後，在係統信息中查詢到的最大編解碼能力依舊是1080P60，

Customer feedback: after tx50 successfully imported the license file supporting 4K, the maximum codec capacity found in the system information is still 1080p60,

客戶現場的TX50軟件版本是：V500R002C00SPC600

The tx50 software version at the customer's site is v500r002c00spc600

解決方案（Solution）

將TX50升級到V600R006C00SPC300的版本後重新導入license文件，查詢最大編解碼能力支持4K，問題解決。

After upgrading tx50 to v600r006c00spc300, import the license file again, query the maximum encoding and decoding capacity to support 4K, and solve the problem.

總結：TX50在V500R002C00的版本下不支持4K編解碼能力，隻有升級到v600R006C00以後的版本才支持H.265 4K的編解碼能力，當TX50啟用H.265 4K*2K能力後，不可降級到V500R002C00版本。

tx50 does not support 4K encoding and decoding capability in v500r002c00 version. Only after upgrading to v600r006c00 version can it support h.2654k encoding and decoding capability. When tx50 enables h.2654k * 2K capability, it cannot be downgraded to v500r002c00 version.
