6. dunno

7. dunno

google is really your friend

Jpeg, acronym for the Joint Photographics Experts Group, who created the formate for compressing image files.

Mpeg - moving picture experts group, a format for compressing video files

I...I..Im too tiresd for this.

The way you could/should have just wiki'd all these but you didn't has angered me.

Also, how can you not know what a timecode is?

i need help with sum bullshit assignment

In your own words explain the following terms:

1. JPEG - compression format for images

2. MPEG - compression format for video

3. 25frames - number of still images per second in PAL format video, most common alternative is 29.7 fps used in NTFS

4. Dropframe - Dropped frames sometimes occurs when converting video recorded in one frame rate to another, see above

5. Timecode - pretty much any timing system ie hours:minutes:seconds

6. Digitalsynchronisation - syncing audio between two devices via digital signals

7. Wordclock -

lemons this is one question out of 4 i have to answer, i was 300 words off the word limit and i hadn't even started to answer the question, i needed the briefest possible answers i could get, and wikipedia doesn't give you that, which is why i asked here, hoping to get an answer like the one flojo just posted.

Refresh rate of screens are measured in Hz. Not frame rates. Those are measured per second.

25 Frames what?

I know that PAL runs on 12 fps , and over in america they run they're shows @ 25 fps.

Not sure if this is gona help or not!

FFS I typed some long sh*t n this PC decided to just delete it all while opening another tab

wont say all I said coz I cnt even remember

but

PAL uses 25 frames per second (interlaced), NTSC uses 30 frames per second (29.97) (interlaced) and film uses 24 frames (progressive, well digital film, dont know if I could technically call the normal analogue film progressive as its film running through a projector), then theres SECAM, but we dont care about that.

PAL is the analogue colour system used in the UK and other countries, NTSC is north America, SECAM is France n a couple miscellaneous countries.

what I was explaining in my deleted post is that PAL systems have a refresh rate of 50Hz and its interlaced.

Interlaced means the image is refreshed one half at a time, so the TV may start by showing the even lines first, then the odd lines, as its only half the image refreshed at a time, its not 50 frames per second, but 25. lines im talking about are the horizontal lines on a screen that define the resolution, PAL and DVB-T (freeview) uses 576 lines, your prob familiar with 720p/1080p resolution for HD content.

interlaced.gif

which leads me onto the "p" at the end of those, thats progressive, same frame rate at 25fps but it loads the full image 25 times rather than half, so its much better for fast moving content like sports for example, although Sky broadcasts its HD in 1080i which the box/tv converts to 720p, no idea why they just didnt use 720p.

we dont use PAL anymore, well 2012 in London, but over here the analogue signal is switched off, so we use DVB-T which is what freeview transmits, still interlaced, but digital.

erm what else, dunno im goin for lunch, anything I missed out or needs more explaining just holler

in the meantime, heres 2 screens showing interlaced and progressive video stills

prog

int

interlaced_160x120.jpg

prob dnt even need to know all that, but it may help u
