What is zvbi
zvbi is:
Television broadcasts use the VBI to transmit text such as closed captioning (NTSC), Teletext (PAL/SECAM), and now Intercast and the ATVEC Internet television encodings. The zvbi library is used to capture and decode raw VBI data.

- zvbi-chains, a wrapper which executes the VBI application given on the command line while overloading several C library calls so that the application can be forced to access VBI devices via the VBI proxy instead of device files directly.
