发明名称 Enabling access to closed captioning data present in a broadcast stream
摘要 A system and method for enabling access to closed captioning data present in a broadcast stream is disclosed. The technology includes a method for enabling access to closed captioning data present in a broadcast stream. The method includes accessing device data associated with a broadcast stream receiver, wherein the device data indicates whether the broadcast stream receiver is configured to receive a digitized format of closed captioning data or an analog format of closed captioning data. Provided the digitized format of the closed captioning data is not present in the broadcast stream, the method includes ensuring the broadcast stream receiver is configured to access the analog format of the closed captioning data.
