    ECM's Explained

    Below is an explanation from someone on another site.
    I do not take credit for this explanation.

    It was well explained, and I thought it might be of value to our own members.

    Cheers,

    When a ECM hits this disables the seeder cards. When the service returns there are a limited number of seeder cards available to use. This means less channels requests can be made to these cards. Too many requests then these cards can not keep up and therefore you get congestion which causes freezing.

    Now IKS Servers cache the control words from the card requests to help off load the requests to the actual cards. These caches normally hold the returned CW for about 18 seconds before the server requests a new cw from the card. During these 18 seconds hundreds of request can come in from the IKS users and the CW is sent from the cache but only one request was sent to the card during that 18 seconds. Now this happens for every single channel that is being watched. To put it in another way, the server has to request a new CW form the available cards every 18 seconds for every channel being watched and this can be a problem when a limited number of cards are available.

    So what providers normally do after a ECM hit is limit the channels being available to cater to the channels that are most watched. This reduces the number of channel request to the limited cards and try to avoid freezing. To clarify this a bit further, as I have already stated that the server caches the CW response from the card, so if for example 1000 people are watching SYFY this means that these 1000 people can watch TV with 1 card request every 18 seconds. Now lets say you have 100 people watching CNN so now you have a card request for a channel that only 100 people use where this request could be used for a channel that is more popular and could service another 1000 people. This is also the reason there are no or very few radio/Sirius channels.

    Now in most cases most P$ providers have a limited number of their own cards and the rest are from upstream main IKS Providers. So if the up stream provider disables the channels there is nothing that can be done until the up stream provider turns them back on. Much like most local utility companies, they may be generating some power in to the local grid but not enough to run the entire city and if there supplier has an outage, there is nothing that can be done until the supplier fixes it.

    So the channels will return when there are enough cards back in the stream, in the meant time quit whining about the missing channels and enjoy what you got. If it is that import for you to have these channels then IKS is not for you, go get a sub and you have to worry about ECM anymore and non-working channels.
