I should also consider that "Ari" or "Arisa" might be part of the branding. Maybe the feature is called "Arisa ImplacableMP4 Exclusive Streaming Module". Alternatively, focusing on the security aspect: "Enhanced Content Delivery with Implacable Security for Exclusive MP4 Media". They might need a feature that includes adaptive streaming, so users get the best quality regardless of their internet speed, while keeping the content secure. Also, maybe offline viewing with access control.
