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.
This package contains the following utilities:
- zvbid, a proxy for VBI devices. It forwards VBI data streams to one or more connected clients and manages channel change requests.
- zvbi-atsc-cc, a command-line utility that captures ATSC TV transmissions using a Linux DVB device and decodes the enclosed Closed Caption data. It can record both NTSC caption (EIA 608-B) and DTVCC caption (CEA 708-C).
- 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.
- zvbi-ntsc-cc, a command-line utility for decoding and capturing closed captioning (CC) for NTSC and webtv.
