An analog TV cannot display progressive-scan DVD media or HDTV signals, which are digital.
So, ATSC tuners are needed to receive on-air HDTV broadcasts. But FTC requires new TVs to have this.
The older "1080" HDTV format (used by CBS, NBC, HDNet, and others) displays 1080 horizontal lines, each with 1920 pixels, using two variations:
The "i" in "1080i" is for "interlaced" presentation, where 540 odd lines are written, then 540 even lines.
The older "480p" is for EDTV (Enhanced-Definition TV) plasma TVs which display HDTV signals at 852x480 pixels.
The newer "720p" HDTV production format (adopted by ABC for HDTV Monday Night Football and MS Media Center and XBox 360) has 720 horizontal lines, each with 1280 pixels.

HDMI (High-Definition Multimedia Interface) connections digitally carries high-bandwidth video signals and 8 channel audio, plus control signals.

Plasma TVs are cheaper to make, but are more susceptible to "burn-in" than LCD panels.

When editing, adjust volume up/down gradually -- slightly before strategic points in the video.
Lead in with sound to help the audience
anticipate the next scene.
In Premiere, open up the audio by clicking the arrow. Click the red line to create an inflection point, which is pulled above or below the dark green line to raise or lower the volume.
Almost every TV sold today has MTS stereo reception and stereo speakers.
Graphic equalizers have markings for hertz and db. One sound mastering technique to make sounds "clearer" is to boost 4kHz by 2-3db, because most humans notice difference in volume every 3 db.
The sound spectrum audible to most humans is from a low Bass of 20 hz to a high of 20,000 Hz (20kHz - kilohertz). Thuds from a subwoofer is about 50-70hz. Human speech (vocals) are around 1-2kHz.
The octave of Western music is subdivided into 12 notes equally spaced on a logarithmic scale, beginning with 220 Hz.

In "Hollywood", camera angles and shots are specified by the director, not the screenwriter.
Including them in a screenplay may detract from its rhythm and readability.
To achieve the "Pan and Zoom" effect where the camera seems to move
around an image, define beginning and ending keyframes.
Key frames specify what the camera sees at
various points in time.
Premiere then uses OpenGL software in real time to smoothly interpolate
pixels from one key frame onto the next.
Any .jpg or .bmp file that does not have a 4:3 pixel ratio
should use Adobe's "Image Pan" video effect.
Still Pan and Zoom
At 4 MB/sec. a firewire connection would take 50 minutes to transfer.
This tutorial from Peachtree Press explains Pan and Zoom.
To enhance DVD-Video with DV-ROM or internet connectivity, use PC Friendly or Player 2.0 from
InterActual.
Several companies have refined the interface by combining both pan and zoom tools into an single (easier to use) interface, including real-time previews:
StageTools' MovingPicture Adobe Premiere plug-in for pan and zoom of
high-res digital flat images.
Imaginate (from Canopus Corp) uses the model of moving a virtual camera over the image versus a fixed camera and moving objects.
