Digital television became a practical proposition around 20 years ago, but at that time the only way to encode and multiplex it involved dedicated hardware. Standard processors simply did not have sufficient power.
Since then we have moved from digital broadcasting to video delivery to multiple platforms. Systems architects had started to build headends using hardware-based encoders, and the tendency was to continue in this way. The result was most networks involve a large variety of proprietary hardware appliances, each of which has its own rack requirements, power supplies and so on.
