Televison 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 three utilities:
o zvbid, a proxy for VBI devices. It forwards VBI data streams to one or
more connected clients and manages channel change requests.
o 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.
o zvbi-ntsc-cc, a command-line utility for decoding and capturing closed
captioning (CC) for NTSC and webtv. |
