    Hi, I'm relatively new to the forum and I enjoy it a lot. Although I consider myself pretty well informed of movie related terms, there are a couple I can't figure out.

    CAV and CLV - I know they have something to do with laserdiscs but what exactly do they stand for?

    JP6 - I know this translates roughtly to "Everyday Joe who prefers Pan+Scan" but what exactly does it mean?

    Lastly what is MARed? I know this means modified from original version (ex open matte or pan+scan) but what is the purpose of "MAR" in caps?

    Thanks.

    J6P = Joe Six-Pack. Meaning, the average unrefined (indicated by the six-pack mention) consumer who doesn't give a flip about OAR, proper equipment calibration, etc.

    CAV = Constant Angular Velocity

    J6P = Joe Six Pack (average citizen)

    ...CLV has slipped my mind though :b

    CLV= Constant Linear Velocity

    CAV LDs hold about 30mins per side

    CLV LDs hold about 60mins per side

    CAV is also sometimes referred to as "Standard Play," with CLV being "Extended Play."

    One thing to note is that a CAV laser disc track consists of up to 54,000 concentric circles while a CLV track is a continuous spiral, just like CDs and DVDs. Each concentric circle on a CAV disc represents a single frame. For those that like to study film sequences and how they develop (particularly animation), CAV is king over all other formats.

    I don't want to get to deep into it now, but, in fact, there ain't no such animal as CLV anymore, but the term has become a convention.

    So I guess all the discs now are actually CLV.
