HTML Multimedia
Multimedia op die web is klank, musiek, video's, flieks en animasies.
Wat is multimedia?
Multimedia kom in baie verskillende formate voor. Dit kan amper enigiets wees wat jy kan hoor of sien, soos beelde, musiek, klank, video's, plate, films, animasies, en meer.
Webbladsye bevat dikwels multimedia-elemente van verskillende tipes en formate.
Blaaierondersteuning
Die eerste webblaaiers het slegs ondersteuning vir teks gehad, beperk tot 'n enkele lettertipe in 'n enkele kleur.
Later het blaaiers gekom met ondersteuning vir kleure, lettertipes, beelde en multimedia!
Multimedia formate
Multimedia-elemente (soos oudio of video) word in medialêers gestoor.
Die mees algemene manier om die tipe lêer te ontdek, is om na die lêeruitbreiding te kyk.
Multimedialêers het formate en verskillende uitbreidings soos: .wav, .mp3, .mp4, .mpg, .wmv en .avi.
