Understanding CCTV: Does H.264 mean more processing power?

The sixth part of the case for H.264 by Mark Harraway, UK Country Manager

Q. Sceptics allege that H.264 necessitates higher-powered processing and there are higher lag times. But elsewhere industry pundits argue that the exact opposite is the case. What is your position on this?

It is true that as you do more work at the encoding end to compress the stream. More processing power is required and this is why you are seeing manufacturers release new hardware platforms for H.264. But as with all hardware, the processing power of the chipsets is increasing exponentially so I don’t see why this should cause more lag on the network since you are reducing the transmitted bandwidth.  What may be happening is that certain manufacturers are using poor quality chipsets or are trying to cut costs generally. Similarly, such scare-mongering could be analogue adherents trying to discourage end-users from deploying H.264 yet again.
