A survey of the latest technology in HDTV-production (English)
Abstract [sv]

Denna rapport ar en granskning av teknik for HDTV-produktion da det kan vara svart for olika TVproduktionsbolag att veta vad for teknisk utrustning som bast lampar sig for produktionsbolagets satt att arbeta och for de produktioner som bolaget gor. Framst presenteras olika kamerasystem for HDproduktion och den typ av kompression som sker i de manga format som de olika kamerorna anvander. Forutom kamerasystem tar rapporten aven upp olika arbetsfloden for nagra typer av system och de framsta mjukvarorna for redigering av HD-material. Olika metoder for lagring och backup presenteras och sist i rapporten fors en diskussion om bland annat for och nackdelar med den teknik som finns tillganglig idag.

Nar ett produktionsbolag ska investera pengar i en fornyelse av sin tekniska plattform ar det viktigt att fundera over vilken funktionaliet man ar ute efter, vilka krav pa kvalite man har och hur den nya tekniken paverkar arbetsflodet. En stor fraga som produktionsbolagen stalls infor idag ar om de ska gora inspelningen pa bandmedia eller om de ska ga over till bandlosa och filbaserade teknologier dar inspelning sker direkt till filer pa minneskort, harddiskar eller optisk media.

En slutsats ar att filbaserade medier ar har for att stanna. Sma men viktiga forandringar i arbetsflodet kravs for bolag som idag spelar in pa band. Framforallt ar det viktigt med rutiner for sakerhetskopiering och lagring av material. Dessa forandringar uppvags av det faktum att filbaserade medier tal tuffare miljoer och storre pafrestningar an bandmedia och att tiden det tar, fran inspelning tills det att man kan redigera materialet, ar betydligt kortare vid arbete med filbaserade medier.

Abstract [en]

This report is a survey of technology for HDTV production with the intent to show the different production companies which technologies and workflows that are available to them. The main topic of the report is HDTV camera systems and compression formats used in the different systems. Other topics are workflows, editing software and methods for backup and storage.

When a production company is investing in new technology it is important for the company to consider the functionalities they need, the quality they require and how the new technology is going to affect the current workflows. One big question for production companies today is whether to stay with tape based media or switch to file based technologies where recording is made on memory cards, hard drives or optical media.

One conclusion in the report is that file based media is here to stay. Small changes in company workflows are required, especially in backup and storage workflows. These changes are compensated by the facts that file based media can stand much harsher environments and that the time from recording to editing is a lot shorter with file based media.
