Abstract: Techniques are described by which set-top boxes receive closed-captioning data streams as input to a Sign Language Interpretation (SLI) library. Depending on the demographics, different SLIs are provided. Additionally, input audio stems, e.g., for video programs without closed captioning, are sent to a speech-to-text processor before the SLI library. The text stream is then converted into sign language view mode in a PIP window for single view mode or to a multiview window for dual view mode. The current accessibility setup menu holds the ‘SLI’ option on/off button. SLI library contains videos for vocabulary which are sequenced in the SLI mode view window based on input text from closed captioning stream. If there is a word without a matching video in the SLI library, then the word itself is displayed in the SLI window. Such words are reported to a server for possible future package release with the additions.
