An external device is the only workable solution for notebook users, also favoring those that don't want to muddle around opening their computers. When buying an external tuner, the best bet is to go for a USB 2.0 or Firewire model. This is because the limited bandwidth of USB 1.1 (11Mbps) isn't adequate for the data passing between the tuner and the PC, leading to playback glitches. External tuners start at around $160 and go up to $300. Like their internal counterparts, the more expensive models feature extra software, cabling and often ship with a remote control.
Many PC users have TV in their computers. There are two most popular types TV tuners installed in PCs: a separate card for a PCI bus, and a tuner integrated into a graphics card. As a rule, all such devices have developed software able to record clips or separate frames into files, compress with MPEG and MJPEG algorithms with the CPU, make records according to a timetable etc. External TV tuners appeared with a USB bus. Today the market offers solutions with the IEEE-1394 and USB 2.0 interfaces. In case of USB 1.0 the maximum throughput is 12 Mbit/s, and it is divided equally between all devices on this bus. And by such external TV Tuner your PC screen can be used as a normal TV monitor independent on the computer itself.
