The answer is "it varies". But I think it's all digital these days.

Advanced codecs take longer to encode because they work on many video frames in parallel. The allows them to find common patterns across mutiple frames, and so increase the compression. But the more frames they scan, the more they have to buffer, so the delay increases. It's unlikely to ever get quicker, as this would reduce the compression or compromise picture quality.
