What is TV tuner card? TV tuner card is one type of hardware which can convert analog signal to digital signal. Output of TV tuner card. Prefer an external or internal tuner. Digital televisions benefits to consumers. (Wide screen, aspect ratio, Dolby sound etc). Choose a tuner with a remote control if you want to watch recordings from a distance. Ensure your software includes desirable features like CD/DVD burning, time shifting, and scheduling. Higher resolution.
How it works? Digital TV Tuner cards for computers are relatively simple pieces of hardware. Include a regular coaxial aerial connector, a RF tuner, and a decoder. The signal hits the antenna, is passed down to the tuner and then to the decoder. The information is then processed by either dedicated MPEG-2 decoder or the computer's processor. A basic digital TV tuner kit will include a TV tuner card and some software to record and watch TV. Include a remote control and infrared receiver, which is used to drive the tuner software. These will often include a digital radio tuner, too, which also allows the user to receive digital radio broadcasts.
Interface: Internal or External Types of TV tuner cards. External or Internal. External TV tuner card.
Chipset Chipset refers to the decoder chip and ca often be a good indicator of the quality of the image. In particular, keep an eye out for cards with chipsets means it is very small manufactured by Philips. Technically, there are two types of digital TV Broadcasts: Standard Definition (SD) and High Definition (HD). SD is broadcast at a resolution of 720x576 which is 576 lines of resolution, while HD supports up to a massive display resolution of 1920x1080 which is 1080 lines. Because HD is broadcasting much more information than SD.
Software Software installation. Ability of software.
Time-shifting Shift how many time? Time shifting also allows you to record shows and watch them later, and because digital TV is broadcast as an MPEG-2 stream. Approximately 1MB per second for an SD stream. HD programs as it records at between 2-3MB per second.
Electronic Program Guides Useful for recording schedule.
