Broadcast Info

The web provides an alternative transmission medium for radio and TV stations, enabling these to reach a global audience. New Internet-only services have also appeared. A large number of services are now available and there are many web-based directories listing Internet radio and TV stations under various categories.

General information such as channel name, category (genre), and broadcaster are provided as well as technical information about the streams (URL, bit-rate, codec etc).

The Problem

Directories which list radio and TV stations have to be maintained by hand because the information cannot easily be collected automatically from web sites. The information these directories provide is not easily extracted by web browsers and devices such as Internet Radios.

Some, but not all of this information is common to audio-info and video-info-examples. However there is an inherent difference between an item of content (e.g. a song) and a real-time stream of content.

Some thought needs to be given to whether this problem can be addressed using the proposed hAudio and hVideo microformats, or by combining these with some new stream-info microformat (similar to the proposed file-format or downloads microformats).

A NOTE ABOUT CONTRIBUTING - USE TEMPLATES

A python script has been written to extract statistical information, but for it to work, we need to be careful about how we mark up information.

Please use the following template when adding information about an Internet radio or TV station:

* [ http://www.example.com Website Name]
** [ http://www.example.com/listing Listing Example]
*** Information displayed: name (i.e. station name), broadcaster, description, language, category (i.e. genre), location, 
                           image (i.e. logo), info_url (station web page), stream_url, player_url, bandwidth, codec, frequency, 
                           rating, now_playing (e.g. track details), schedule, email, stereo (i.e. stereo/mono flag)

If you need to add more information than is displayed, please use a common term to describe the information.

Existing Practices

Listed below is an overview of the existing patterns and practices found in the wild for Radio and TV stations.

Summary of common patterns discovered

  • There are often several streams listed for the same station using different bit-rates or codecs.

Other attempts to solve The Problem

  • media-info-examples - Attempted to find an uber-microformat for describing media. Turned out to be too large of a task, thus the problem was split into attempting to create microformats for audio, video and images.
