FIELD NOTES

Guides to internet television

Practical explanations for viewers, channel teams and playlist maintainers—written for decisions, not search-engine filler.

What is an M3U playlist?

A plain-text map from channel labels to media addresses—and the metadata that makes a large list usable.

02 4 min

The names look like different technologies, but the practical difference begins with text encoding—not stream quality.

03 6 min

A working media URL can still fail on the web because playback is a chain of DNS, TLS, CORS, manifests, segments and codecs.

04 5 min

CORS is the permission a media server gives a webpage to read its responses; it is not a player switch that viewers can safely bypass.

05 4 min

An HTTPS page cannot safely assemble a live programme from insecure HTTP manifests or segments.

06 5 min

Status records describe an import-time observation and a known failure class—not continuous monitoring or a permanent promise.

07 6 min

A public playlist snapshot is parsed, filtered and recorded without turning link availability into a permanent guarantee.

08 4 min

Send enough context to reproduce a failure while keeping account details, signed links and personal data out of the report.

09 5 min

A useful playlist report does not need to upload the playlist: modern browsers can parse, count and compare entries on the device.

10 6 min

A programme guide becomes useful only when a stable channel identity, schedule timezone and licensed data source line up.
