Part VI
Pseudo-Analog Transmission
In the current digital communications systems, image and video are compressed
fully and thus the redundancy is completely removed in the compressed data. How-
ever, in the analog communications systems, image and video are not compressed
at all. In this part, we are looking for new communications systems between digital
and analog systems. A typical feature in such systems is that entropy coding is re-
moved in source compression. Furthermore, when source is no longer entropy coded,
conventional bit-based channel coding is unsuitable to source protection. Another
typical feature in such systems is that channel coding is removed in data protection.
Although the transmission is still implemented in a digital ...
