The wide diffusion of e-learning technologies represents a great opportunity for underserved segment of the population. This is particularly true for people with disabilities, who may have difficulties attending traditional on-site learning programs or accessing to conventional (printed) learning materials. The creation and provision of accessible e-learning contents are crucial aspects in ensuring that e-learning becomes an inclusive technology. This paper presents LOT (learning objects transcoder) a system designed and developed to automatically produce different accessible/portable versions of audio/video learning materials. The system offers a broking service to transcode digital video lectures included in a LO that full fits a specific student profile, focusing specifically on his/her accessibility requirements
