What is EPG ID Channel Mapping Matrix?

Protocol Definition & Architecture: Definition And Guide

Technical Definition

The mapping matrix links each stream tvg-id to a <channel id> in the XMLTV guide. Mismatches, duplicates, or regional variants (e.g. ESPN East vs West) are the most common cause of missing or wrong guide data.

How It Operates Under the Hood

Panels maintain a table of stream_id → epg_channel_id; the player compares tvg-id strings case-sensitively. Normalisation (lowercase, strip spaces, country suffix) and fuzzy matching in players like TiviMate recover most mismatches.

Beginner to Engineer Guide

EPG ID Channel Mapping Matrix matters to subscribers because it directly affects how quickly a channel starts, how stable it stays, and how the guide and catch-up behave. For resellers it determines which players and devices to recommend and which panel settings to expose.

Xtream Codes v2 REST API Deep-Dive

Every modern player connects Reference Panel through the same HTTP handshake. The sequence below is what TiviMate, IPTV Smarters, and XCIPTV execute on login; you can reproduce each call in a browser or with curl.

1 Authentication handshake

HTTP Request
GET http://line.server.example.com:8080/player_api.php?username=USERNAME&password=PASSWORD
JSON Response (user_info + server_info)
{
  "user_info": {
    "username": "USERNAME",
    "status": "Active",
    "auth": 1,
    "exp_date": "1798761600",
    "is_trial": "0",
    "active_cons": "1",
    "max_connections": "5",
    "allowed_output_formats": ["m3u8", "ts", "rtmp"]
  },
  "server_info": {
    "url": "line.server.example.com",
    "port": "8080",
    "https_port": "2086",
    "server_protocol": "http",
    "timezone": "UTC",
    "timestamp_now": 1759795200
  }
}

auth must equal 1 and status "Active". exp_date is a Unix timestamp; max_connections caps concurrent streams; https_port exposes the TLS listener used to defeat SNI-based shaping.

2 Live category indexing & stream URL construction

action=get_live_categories
GET http://line.server.example.com:8080/player_api.php?username=USERNAME&password=PASSWORD&action=get_live_categories
Category Index
[
  { "category_id": "12", "category_name": "UK | SKY SPORTS", "parent_id": 0 },
  { "category_id": "18", "category_name": "USA | ESPN & FOX SPORTS", "parent_id": 0 },
  { "category_id": "41", "category_name": "24/7 | PPV EVENTS", "parent_id": 0 }
]
action=get_live_streams + stream URL template
GET http://line.server.example.com:8080/player_api.php?username=USERNAME&password=PASSWORD&action=get_live_streams&category_id=12
# Stream URL template returned per stream_id:
http://line.server.example.com:8080/live/USERNAME/PASSWORD/STREAM_ID.ts
http://line.server.example.com:8080/live/USERNAME/PASSWORD/STREAM_ID.m3u8

3 EPG XMLTV synchronisation routine

XMLTV fetch (gzip) + short EPG
curl -sS --compressed "http://line.server.example.com:8080/xmltv.php?username=USERNAME&password=PASSWORD" -o guide.xml
# Short-form EPG for a single channel (JSON, base64 descriptions):
GET http://line.server.example.com:8080/player_api.php?username=USERNAME&password=PASSWORD&action=get_short_epg&stream_id=STREAM_ID&limit=4
XMLTV excerpt (tvg-id must match channel id)
<?xml version="1.0" encoding="UTF-8"?>
<tv generator-info-name="Reference Panel EPG">

EPG ID Channel Mapping Matrix FAQ

What is EPG ID Channel Mapping Matrix in simple terms?

The mapping matrix links each stream tvg-id to a <channel id> in the XMLTV guide. Mismatches, duplicates, or regional variants (e.g. ESPN East vs West) are the most common cause of missing or wrong guide data.

Can I remap a channel to a different EPG entry?

Yes; TiviMate and OTT Navigator let you pick a guide source per channel manually.

What is the difference between Xtream Codes API, M3U URL, and Stalker Portal login?

All three deliver the same channels. Xtream Codes API uses player_api.php JSON endpoints so the player lazy-loads categories and EPG in seconds. An M3U URL (get.php) downloads a single text playlist of every stream, which is slow with 45,000 channels but works on any player. Stalker Portal authenticates by MAC address through a /c/ portal URL and is used by MAG receivers and some Smart TV apps.

Why is my EPG guide empty or showing programs at the wrong time?

Players fetch an XMLTV file from xmltv.php and match each channel by tvg-id. An empty guide means the player downloaded the file before the server finished its 15-minute refresh or the file exceeded the player size cap (set TiviMate EPG update to "never limit"). Wrong times are a timezone offset issue: XMLTV timestamps carry +0000 and the player must apply your local offset, so set an EPG shift of +1 or -5 hours in the channel settings rather than changing the device clock.

How far behind live are IPTV sports streams and can latency be reduced?

Standard HLS with 4-second segments and a 3-segment player window sits 12-18 seconds behind the broadcast. Low-Latency HLS with 0.5-second partial segments brings glass-to-glass delay to about 3.8 seconds, and raw MPEG-TS over HTTP (.ts output format) is typically 5-7 seconds behind. Choose the .ts output format in your player for live sports and reserve .m3u8 for VOD and catch-up.

What buffer size should I set in TiviMate, Smarters, or XCIPTV for 4K sports?

Set the largest option (5,000 ms in TiviMate, "Large" in Smarters). Buffer time in seconds equals buffer bytes multiplied by 8, divided by the stream bitrate in Mbps: a 15 MB allocation on an 18.5 Mbps 4K feed yields 6.5 seconds of protection, which covers typical ISP shaping bursts of 2-4 seconds without a visible freeze.

Do providers offer a free trial and how long does activation take?

Every network in this directory issues 24-hour trial lines from the reseller panel. Activation is instant: the panel writes the line to the Xtream database and the player can authenticate within 10 seconds. Trial lines are usually limited to 1 connection and exclude PPV bouquets.
