• Translate CEA-608 captioning to equivalent CEA-708 captioning
• Render CEA-708 & 608 closed captioning onto video frames
• Convert plain text to CEA-708 & 608 closed captioning packets

C-Caption SDK

The C-Caption™ SDK is a simple to use C library, with associated headers and documentation, that accomplishes closed captioning translation, closed captioning rendering, and caption conversion.

Optional Inputs:

• Plain text from speech recognition
• SCC or other transcribed captioning format
• Device Context (handle) that conforms with the target video frames to be overlaid with rendered captions
• Callback function pointer to user defined text renderer engine
• Closed Caption DTVCC user_data as CEA-708 and CEA-608 commands and caption text

Optional Outputs:

• Caption text characters properly synchronized and rendered onto the input Device Context for compositing onto the video frames
• CEA-608 packets created from text or transcribed captions such as .SCC
• DTVCC CEA-708 packets generated as equivalent to input CEA-608 packets
• SCC transcribed captioning format converted from plain text input
• Caption debugging displayed on screen and/or log file

Applications:

• Closed Caption Display Visualization on Associated Decoded Video
• Caption format and specification translation
• Open Captioning (compositing permanent ‘Subtitles’)
• Captioning Quality Inspection
• Closed Captioning Analyzer
• Closed Captioning Debugging and Verification

Specifications:

• Compliance: CEA-708-E and CEA-608-F
• Extended Character Sets: Chinese, Danish, English, Finnish, French, German, Hebrew, Italian, Japanese, Portuguese, Spanish, Swedish, & Taiwanese
• Supports Unicode text character set

Supported Operating Systems:

• MS Windows 10, 8, and 7
• Mac 10.12 or later
• Linux (custom built to user's distribution and version)

C-Caption™ is optimized for minimal processor load and faster than real-time with multiple 608 and 708 captioning channels.
