Why do HDTV built-in scalers suck?

Upconverting DVD players, standalone video scalers and the like should not have to exist. HDTV sets have built-in scalers, but they all do lousy jobs of converting non-native resolutions full-screen, giving consumers a reason to buy hardware that does something built into their HDTV sets.
Is there a reason for this? It's understandable that some cheap HDTV set would be cheap in part because the manufacturer cut corners by using a cheap scaler, but what excuse is there for top-of-the-line HDTV sets having lousy built-in scalers? You shouldn't have to spend hundreds or thousands of dollars on what should be redundant products after paying thousands of dollars on your HDTV set to get a good experience out of it.

Samsungs are bad for SD signals and audio delays. Some are good like Sonys.
I agree it is stupid though, but when this better scalers costs $20 more and times that by 100,000 the difference is important.
Sony makes you pay for that difference but for me it is well worth it.

Given the varieties of control options and the amount of circuitry on my video scaler / deinterlacer / hub, I'd say TV manufacturers don't want to open that kettle of fish. The whole SD/HD versus other video input formats is an interface nightmare.

Cheap displays with cheap components. There are better sets out there that cost a lot mroe. They do a better job. A good scaler can cost more than a cheap display. There's more to HD than just the resolution.

I don't mind the scaler in my Samsung. It's the compression on my Cable that really ticks me off.

Built-in TV scalers will never do that great of a job because the signal they display is so compressed, especially cable. It ends up scaling compression artefacts an making it worse. In HDTV we go from a 1.5Gbps uncompressed signal to 19.4Mbps on cable. In SD it goes from a 270Mbps uncompressed signal to 3.5Mbps on cable. So basically to go from a 720x480 source to a 1920x1080 result, a scaler has to scale by almost 700%. Try to scale an image by 700% in Photoshop just for fun. I work for a TV broadcaster and the upconverters (scalers) we use are about 20,000$ each.

It's about appreciating what you have. The grass is always greener on the other side.

It might be an attempt to move consumers away from technology they already own. They try to upscale their DVD stuff into HD realize it's awful, and end up buying a bluray or HDDVD device. Good way to jumpstart the industry which is otherwise not doing to well.
