Shuhei Yoshida has chimed in on why he thinks PlayStation TV isn't performing as well as Sony had hoped.
According to the Sony president of worldwide studios, it isn't easy explaining the concept behind the device.
PlayStation TV review: An impressive library of games, but who is it for?
"It didn't capture the consumers' imagination," Yoshida said to Game Informer.
"It's a hard concept to explain. You could say it's a mini-console, it's a video streaming device. If we say it's a mini-console, like other mini-consoles, people expect a better device like PS4 or Xbox One. It's short in that delivery."
He added: "When you say it's a video streaming device, there are other devices with higher def video. It has some unique things like remote play of PS4 games.
"It can do many things, but it's not easy to say this one thing is extremely good. I think that's the reason we were not able to convince people at the original price."
PS TV made its European debut last November. In addition to PS Vita compatibility, it also lets users stream PS4 and PlayStation Now games.
The device recently received a price cut in the UK. Representing a saving of 47%, the device is available for £44.99 from most retailers, down from the original price of £84.99.
