It depends upon the amount of lag you get. Virtually all video broadcasting systems rely on MPEG encoding, as does thre Phantom. One of the characterisitics of MPEG is that in order to obtain the best compression, it checks to see if the image is changing much from one frame to the other. If not, it simply encodes a message of 'essentially the same as the last frame'. In order to do this, it has to delay the encoding process, and that is what you see as lag. You can get the same effect if you have two television sets in the same room tuned to the same channel, often one will be delayed beghind the other. So, in summary, a small amount of lag (ip to 1/2 second) is perfectly normal. |
