是因為你們需要這方面的特殊要求嗎?Hi Shgihara san,Here are some instructions1. As shown in the figure, the function of CaPPV is optional. Without this function, why can't it be sold? Is it because you need special requirements in this regard?2. Last time Shigihara San came to the meeting, adviser explained to Shigihara San that we only support 4K data broadcast and do not support the extra functions of HTML5. You accept the explanation .Please consult together about the things, thank you.
