Chances are, you will be completely floored at the amount of money and effort required to deliver you HD-content. Engadget HD took a trip down to WFTS ABC 28 to see their setup, as they are first local-news channel to provide their cast in HD. The amount of various machines, cables, buttons, cameras… is quite impressive, to say the least. Not to mention incredibly expensive, which is why HD-content as a whole is slow to catch on.
So, 4 months and about 1 million dollars later, they produced the first local HD broadcast on July 28th, 2007 — this didn’t include the $800,000 in cameras they bought the year before. You’d think the cameras would be the biggest expense, and while they’re probably the single biggest, you still have to buy an HD switcher, encoder, sync-master, HD video server, as well as a whole list of other equipment and cables.
