This package provides objects for representing messages exchanged via the DVB CSS-WC protocol and for implementing clients and servers.
The WC protocol is a simple UDP request response-protocol that enables simple clock synchronisation algorithms to be used to establish a common wall clock between a server and client.
There is a :class:`~dvbcss.protocol.server.wc.WallClockServer` class providing a self contained Wall Clock server. The :class:`~dvbcss.protocol.client.wc.WallClockClient` is designed to allow different algorithms to be plugged in for acting on the results of the request-response interaction to adjust a local :mod:`~dvbcss.clock` object to match the Wall Clock of the server.
Modules for using the CSS-WC protocol:
- :mod:`dvbcss.protocol.wc` : objects for representing and packing/unpacking the protocol messages.
- :mod:`dvbcss.protocol.client.wc` : implementation of a client for a CSS-WC connection.
- :mod:`dvbcss.protocol.client.wc.algorithm` : algorithms to be used with a CSS-WC client.
- :mod:`dvbcss.protocol.server.wc` : implementation of a server for a CSS-WC connection.
