In Amazon's "Prime Video Channel", contents including live streaming are being delivered.

There are " TiVo " and " Slingbox " as recorder capable of recording the content being streamed, but on Amazon's Fire TV you can watch the content being streamed, but you can not save the video was. For this reason, as a recorder capable of recording content, development of the code name "Frank" is being advanced.

Lab 126, which is known for smartphones, Fire Phones , Smart Speakers, Amazon Echo , Household Robots, Vesta, etc., is responsible for development.

However, Frank's plan is that the final decision has not yet been made and there is a possibility of cancellation or delay.
