Soundy 1 Posted July 16, 2011 http://lmgtfy.com/?q=multicast IP multicast is a method of sending Internet Protocol (IP) datagrams to a group of interested receivers in a single transmission. It is often employed for streaming media applications on the Internet and private networks. Share this post Link to post Share on other sites
mujju_433 0 Posted July 24, 2011 Hi soundy, Have you ever used this option in your DVRs ? could you please tell me how it works? Do you mean to say , when the camera is sending the packets to the Network , does that mean many people can view the camera from its webpages? or is it something different? Thanks and Regards Share this post Link to post Share on other sites
Soundy 1 Posted July 24, 2011 I've never used it, no... the exact implementation would depend on the specific DVR and how its manufacturer uses it, but I would expect the idea is for it to operate similar to a UPnP media source... like Home Sharing with iTunes, where the server just "broadcasts" that it has the content available, and any suitable receiving device can receive and stream it.

thewireguys 3 Posted July 24, 2011 Multicasting is designed to reduce network bandwidth when you have multiple clients or redundant NVRs. You well need network switches that can support this. Share this post Link to post Share on other sites
Soundy 1 Posted July 24, 2011 Ah yes, good point - your switch or router has to support multicasting for the packets to make it beyond the DVR's port. Not all switches do. Share this post Link to post Share on other sites
