I'm new at telecommunications so this may be a simple question, but somehow I can't get my head around this. Can someone explain me in simple words how the terms DOCSIS and DVB-C are related? Both are "standards that define how to transmit data over HFC infrastructure", but what exactly defines DOCSIS and what DVB-C? Is DVB-C a standard for the signal and DOCSIS for the receiver?

    DVB-C is the medium where the signal is received. DOCSIS is the technology that uses the medium to create the network connection.

As I understand it.



DVB-C is a standard for broadcasting digital TV over cable TV networks while DOCSIS is a standard for providing general purpose bidirectional data communications over cable TV networks. Both are likely to coexxist on the same cable infrastructure as most providers provide a mix of broadcast TV and "broadband" data service.



It seems that the European variants of Earlier versions of DOCSIS borrow the low level modulation techniques from DVB-C (with the american versions using an ITU standard), while the newever versions allow a broader range of modulation depths .

    DVB-C and DOCSIS coexist on the same medium using frequency-division multiplex (FDM). Each one uses a frequency band dedicated to it.



    Basically, DOCSIS uses several DVB-C channels (6 or 8 MHz each, depending on whether DVB is using NTSC or PAL). Within the DOCSIS segment, time-division multiple access (TDMA) is used to separate downstream and upstream - in contrast to television broadcasting, a network connection needs to be bi-directional. Later DOCSIS versions added code-division multiple access (CDMA) to make better use of the spectrum.

                      One-line joke

                      A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
