    The encoder/decoder question is up to the nature of your project. Here is a link to some information - http://www.holtek.com.tw/english/docum/consumer/2_12e.htm.

    I suppose it would be handy for a large remote control system with multiple stations to be addressed. Is this the nature of your project?

    Encoders/decoders help avoid interference from noise, if you are using any sort of wireless link. You can do the same thing in software.

    The HOLTEK encoder/decoder devices you have referred to permit you to divide your single RF link into separate subchannels. Each subchannel possesses a unique address. This greatly facilitates the sending of different digital commands to the same receiver. It also makes it possible to have multiple receivers each with its own unique address.
