DETECTING AND PROCESSING MULTIPLEXED CLOSED CAPTION DATA

摘要

Methods, systems, and computer readable media can be operable to facilitate the detection of a closed caption standard and corresponding extraction of closed caption data according to the detected closed caption standard. A set-top box (STB) may receive content from multiple different networks and/or service providers, and closed caption data may be formatted differently in content received from the various networks and/or service providers. The STB may identify a relevant standard with which to process closed caption data in a received content stream based upon an identification of the network and/or provider from which the content stream is received, and the STB may extract and render closed caption data using a process associated with the identified network and/or provider.
