Codec complexity translates to operational costs

Indicative encoding costs (large operator)


Other Costs to consider

> Royalties• Per device, per subscriber, per title• Poorly defined licensing pools and undeclared patent holders

have been a barrier to HEVC adoption> New equipment/integration

• New encoding hardware/software• Operating multiple codecs for different devices is expensive• Required updates to consumer devices and apps
