How could a blind alien race interpret video broadcast into space?

I've got a race of aliens that have no sense of sight. They can measure electromagnetic radiation with instruments, but have no concept of vision.

All I know about video encoding and transmission is that it happens, so my question is very basic.

Humans have sent TV shows into outer space. Would it be plausible for aliens on a tech level similar to ours to interpret the video data as a tactile image?

Would the methods needed be significantly more difficult than interpreting it as a visual image? I'm asking this part since it the video was sent with the intent that it be interpreted visually, and I have no clue what that means in practical terms.
