Talk:Channel surfing

From Wikipedia, the free encyclopedia

An ATSC signal can be locked onto and start being decoded within about one second, while it can take several seconds to begin decoding a DVB signal. So that's why a TV program starts a few seconds later when I watch it on Sky. 1001001001111100000 02:18, 19 April 2007 (UTC) PS: I found this out by smuggling a 14" into the lounge and watching the same channel on both TVs.
