There are many different kinds of movies that were first used for surround sound. To be more specific movies such as Star Wars which were very popular.
Sound-on-film has existed since 1927, but it has only been in a digital format since around 1992. Disney films created before then (like all other sound films) recorded the sound effects and music on analog media. It was synchronized onto the film strips using either magnetic (just like a cassette tape) or optical (usually the RCA Photophone) formats. Most 35mm films still include an RCA Photophone track, in case the theater is not equipped to run digital sound or the digital equipment fails.
So as to pack in more information. Broadcasters were required to use the same channel space when they went digital as they were originally assigned by the FCC. However, the new digital hidef information, including the surround audio, would have taken up at least six channels worth of space. By compressing the data (removing redundant info), they're now actually able to put more programming into the same amount of space.
The signal sent to the TV must be a digital signal as well.

Digital Signal Processing
Connect the digital audio output from the TV to the digital input of the surround sound receiver.
Virtual surround uses 2 speakers to simulate the effect of a wider stereo image and surround speakers using digital processing. It is not as effective as real surround sound, which uses real rear and surround speakers.
If your TV has a digital audio output, connect it to the optical or coaxial digital input of the surround receiver. This will pass through the digital audio signal sent from a HDMI input at the TV.
Dolby Digital Surround Sound.

Delay Designer 5.1 (digital delay) and Space Designer 5.1 (reverb) are the two surround effects for surround mixes. They can only be used on surround channels.
Dolby Home Theater is a suite of effects for providing laptop computers with surround sound capability, including virtual surround through headphones, extended bass response and dolby digital signal creation through a digital output.

You will need a digital audio switchbox or a surround sound receiver with 2 digital inputs.
A 2-channel digital audio signal, or a encoded DTS or Dolby Digital surround sound audio stream.
If your receiver has an HDMI input, use that. If it doesn't, then you will have to use analog or digital audio connectors to plug it in.
Connect the audio out of the TV to the audio input of the surround receiver with a dual RCA cable. Note that this connection isn't surround. You will need to connect a DVD, Blu-Ray or digital cable box to the surround receiver for true surround sound.
