Gemini

Gemini is a three gigabit, high definition, or standard definition serial digital interface dual closed caption encoder (3G/HD/SD-SDI CC Encoder) with captions over IP. It accepts 3G/HD/SD-SDI transport streams and gives four closed caption encoded outputs of the same format as the input, with the option of two of them being decoded. The SDI outputs are re-clocked, making the SDI output eye pattern generally better than the input. It is a better re-clocker than most re-clocking Distribution Amplifiers (DA). The unit will pass ANC data untouched including audio to the output.

The Gemini will encode two SDI streams at the same time. The encoded data from the captioner(s) can be encoded to single SDI stream or to both SDI streams. Two captioners can send data to each SDI stream individually or one captioner can send data to both SDI streams. Each stream will have an SDI encoded output and a decoded SDI output. The audio from the primary SDI stream can also be used as a USB microphone when connected to a local PC and that input can be used for other streaming services (Zoom) or speech recognition software.

The Gemini will encode line 21/22 CTA-608 waveform and/or encodes SMPTE 334 Caption Data Packet (CDP) for SD. The Caption Data Packet will contain a header, CTA-608 data, CTA-708 data, caption service descriptor, and a footer. For HD it will encode the caption data packet. It has RAM that is reserved for XDS packets, the packets will be inserted into CTA-608 field 2 based on XDS packet priority and field 2 availabilities. The unit also has XDS menus for Parental Guidelines (V-Chip) and Transmission Station Identification (TSID) packets. The RAM can be filled using V-Chip software.

The Gemini has 8 GPI controls 4 for each SDI stream. For each SDI stream the GPI controls are remote encode bypass switch, encode/port switch, decode channel/service switch, and a Weather Lift (AKA Legalizer) switch, with a menu that allows you to select the number of lines to be lifted. The FCC has mandated that captions are not to be displayed over things like people’s names, school closings, and so on. This has become a major issue with broadcasters. Gemini also has a decoded output and caption data recovery for quality monitoring. USB connection allows for web GUI to PC. Remote monitoring/controlling is also possible through the GUI.
