Playback of videos can be limited to only be visible from a single domain (eg www.paginacliente.com) or a list of domains. Content may be protected by username and password to set the level of access to certain videos (free, PPV), which is ideal for online video rental platforms. We can insert watermarks within individual frames, use encrypted protocols like RTMPE streaming, security tokens and player authentication so that only those video players can connect to the authorized streaming servers to reproduce the signal.
