问题描述

客户反馈TX50导入支持4K的license文件成功后，在系统信息中查询到的最大编解码能力依旧是1080P60，

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

客户现场的TX50软件版本是：V500R002C00SPC600

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

解决方案（Solution）

将TX50升级到V600R006C00SPC300的版本后重新导入license文件，查询最大编解码能力支持4K，问题解决。

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

总结：TX50在V500R002C00的版本下不支持4K编解码能力，只有升级到v600R006C00以后的版本才支持H.265 4K的编解码能力，当TX50启用H.265 4K*2K能力后，不可降级到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.
