InnoCaption only provides IP-CTS. By law, InnoCaption is not and cannot be a substitute for CART or in-person transcription because those services are not covered under the TRS fund.
FCC differentiates between the IP CTS and CART (live-event captioning). CART provides a complete translation of all spoken words and environmental sounds for the benefit of an individual consumer or larger group in a variety of settings, including classrooms, courtrooms, religious services, conferences and so forth. CART is a fee-based service.
