WebTV Hardware
The hardware needed to insert WebTV crossover links is identical to the hardware needed to close caption video tapes. Inserting crossover links is an extra added feature in the CaptionMaker software.

Encoding
Digital Encoders
Analog Encoders - An encoder is the central piece of hardware needed to close caption videos and insert WebTV crossover links. The CPC CaptionMaker outputs data into the encoder through an RS232 connection, and the encoder outputs it into line 21 of the video tape. Closed caption data and WebTV crossover links can be inserted into a video at the same time.

Time Code
Time Code Readers and Generators - A time code reader card, which is installed into your computer, reads timecode from a VCR and is used to "sync" the captions with the video in your final product. It is important for WebTV links, you can also sync the WebTV links with the timecode in order to have the links display at the desired time in the video.

Video Related Devices
VGA Capture Device - Device inputs video from a VCR into the CaptionMaker program. Although it is not required, it is recommended. It is very useful for positioning the captioning data, and is a great space saving, cost-effective alternative to a Television monitor.

VCR A VCR is the final necessary component for a Webcast-only captioning system. The VCR is used in conjunction with a time code reader and video input device to sync the captions with the audio. For Webcast-only purposes, a high quality VCR is not necessary, you can purchase a $100-200 VCR. CPC does not sell VCRs.
