System and method for detecting closed captioning and creating a closed captioning electronic programming guide

摘要

A set-top box device includes a detector module and an electronic programming guide module. The detector module is configured to detect a closed captioning flag in a video stream, and to cache electronic programming guide information for the video stream if the video stream includes the closed captioning flag. The detector module is further configured to create a closed captioning electronic programming guide including the electronic programming guide information. The electronic programming guide module is in communication with the detector module, and is configured to output the closed captioning electronic programming guide.
