软件包: zvbi (0.2.35-19)

Vertical Blanking Interval (VBI) utilities

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.
