What is a Set-Top Box (STB)?

A digital set-top box may be needed for receiving digital TV broadcasts, because most older TV sets don't have a digital tuner.

An STB is a device that receives and decodes digital television (DTV) broadcasts so they can be displayed on analogue television sets or other display devices, such as computer monitors or projection screens. These can be SD or HD broadcasts, depending on the type of STB you use. In the most straightforward configuration, you simply plug the STB into your existing aerial and TV set, using either a composite, S-Video or component video cable. It will usually scan and find any available channels. The STB then receives the digital stream being broadcast and decodes it so your existing analogue TV can understand it. You can, of course, also connect it to your sound system and VCR.

Set Top Box with HDTV Basic SD-STBs can cost as little as $100 or so, while HD-STBs usually cost a few hundred dollars more. The price of both types of STB can vary widely, depending on their feature set. As mentioned previously however, there is no point getting an HD-STB unless you have a high-resolution screen to use with it, and even if you do, the lack of HD content means that a lot of the time you will be viewing programs in standard-definition.

Don't let that put you off, though. If you want the ultimate in quality, more HD content is gradually being made available and quite simply, nothing else compares (there are also a number of SDTV and HDTV tuner cards available for PCs and even external USB-based Digital TV receivers for notebook computers).

Inside the box

A typical STB has one or more microprocessors for running the operating system (OS), possibly Linux or Windows CE, PowerTV, JavaOS or any one of a number of small "embedded applications". To the end user, it doesn't really matter what OS is used and usually it is not able to be accessed by the user. A set-top box also includes RAM, an MPEG decoder chip, and more chips for audio decoding and processing. Again, they include everything required and are usually not upgradeable.

The future of STB

It is really confused me because as we know, the STB is really needed for every families. However, the STB companies are still hard in this era for them. WHY?

set top box

I am trying to connect a Centrex CTDTV100 STB to a TCL LCDTV15E75S but the instructions do not seem very clear. The best I can get is a B&W picture and no sound.

If you can give me clear directions, I would appreciate it.
Thanks,
Vernon

Can you turn any analogue tv into digital with a set top box? Does it need to be a "digital SD or HD"?

digital tv reception problems

Have just installed a digital set top box.

Occasionally picture breaks up, but no more often than we experienced with trhe analogue signal.

However picture and sound frequently stall, stutter and skip - as in a faulty DVD.

Signal level is reported as 60% on average, quality 90% and greater.

Where do we start looking for a solution?

The same thing happened to me after a similar timeframe. As Dick Smith sells Std definition set top boxes (currently for $37) although I bought 3 @ $27 each. I'd just replace your set top box.

my Tivo set top box was working fine with my TV but since last night it's been 'stuck ' on Channel 7 (I live in Adelaide). I can get only 7, 71, 7HD, 72 and 73. My remote signals all channels, which initially show up on the TV monitor, but they default to 7 on the set top box display. Can anyone figure out what's happening and how I might fix this problem?
Thanks

Can I connect a set top box to a HD digital TV, that does not have an audio out of any kind, by using the aerial in and out of the set top box and then use the audio out of a set top box for head phones or speakers? Will this connection cause any disruption to the TV operation?
