## What it is
TSDuck is an extensible C++ framework and toolkit of command-line tools for manipulating, analyzing, monitoring, and transforming MPEG transport streams. It supports DVB, ATSC, ISDB, SCTE, HLS, SRT, RIST, and professional hardware through a modular plugin architecture centered on the tsp transport stream processor.

## Use cases
- analyze an MPEG transport stream's PSI/SI tables, bitrates, and timestamps
- monitor a live DVB or IPTV stream and report TR 101 290 metrics to Grafana
- extract or inject EPG/EIT tables into a broadcast stream
- process SCTE 35 splice information for ad insertion
- transmodulate a transport stream between DVB, ATSC, ISDB, ASI, and IP multicast
- capture streams from a USB DVB tuner or Dektec hardware
- emulate a DVB SimulCrypt CAS head-end with ECMG/EMMG
- manipulate transport stream tables and descriptors via XML or JSON

## When to choose
- you need a comprehensive, scriptable command-line toolkit for MPEG-TS testing, debugging, or monitoring
- you work with broadcast standards like DVB, ATSC, ISDB, SCTE 35, or Teletext
- you need to interface with professional hardware such as Dektec or HiDes devices
- you want an extensible C++ library to build custom transport stream processing applications

## When to avoid
- you need a GUI-based video player or editor
- you only need general-purpose media transcoding (use FFmpeg instead)
- your content is not transport-stream based (e.g., plain MP4/WebM workflows)

## Facets
- artifact type: framework

- function: developer-tools, cli, monitoring, streaming, plugin-system, sdk
- domain: media, developer-tools, networking
