DVB-C2 available for TV EXPLORER HD+

DVB-C2 is the second generation digital

transmission system for cable networks.

It employs the most powerful coding techniques

and modulation schemes so that Cable TV

operators can make the most efficient use of

their networks. The first field tests show that

DVB-C2 will allow for about 50% more digital

transmission bandwidth regarding DVB-C.

In the immediate future, supporting DVB-C2

will be a must for a field meter. The

TV EXPLORER HD+ already offers DVB-C2

as a separate option.
