Furthermore, the parallel interface required expensive and nonstandard multicore cable
(although over very short distances it could run over standard ribbon cable) and the D25
plug and socket are very bulky. Today, the parallel interface standard has been largely
superseded by the serial digital video standard, which is designed to be transmitted over
