A high definition camera will start out at around $700.00 for good quality.
you need a camcorder You not only need a camcorder but a DV camcorder. If you have a new High Def camcorder, you will not be able to do webcast because the image to be processed is too high in quality and would take a long time for computer to process it. A regular mini DV camcorder would actually work great.
It depends if the camcorder has the physical settings to attach the lens.
High quality high definition broadcast antennae actually work quite well. More expensive types can pick up stations from as far as 75 miles away.
You can hook up your camcorder to a TV and it will work just fine. The same goes for a computer.
only with a converter box, but then it becomes just standard definition
All VCR's work with High Definition tv's,but you'll usually only be able to play back and record in standard definition or Super VHS.
The third generation Sky Digibox will allow you to receive digital satellite broadcasts in high definition. It is called a SkyHD Digibox.
No reason why not - so long as the memory card is the correct type for the camcorder (HD/SDHC etc)
Any sony memory stick will work.
Usually you cannot buy an added piece to increase the zoom on your camcorder and have to work with the features that the camcorder originally came with when it comes to that .
IF you have the newer versions hdmi cables will work on the xbox.
Camcorders do not tend to work well in very cold temperatures.
