## Abstract

A multimedia content distribution system creates and distributes content files that contain content that may be viewed or displayed using commonly distributed viewer or player programs. A second portion of the content files may be viewed using specialized viewer or player programs.

## Claims

### Claim 1

A method comprising:
creating a video file having a first content area containing a first video and a second content area containing a second video, the video file formatted according to a first video standard;
encrypting at least a portion of the second video in the second content area, the second video is not viewable using a first video standard player, and the second video is viewable using a specialized video player;
wherein video content in the first content area includes instructions that, when played by the first video standard player, instruct a user on how to download the specialized video player that can access the second video;
storing the video file along with a plurality of video files;
distributing one or more stored video files to client devices.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
receiving a request from a client device for a specialized video player;
sending the specialized video player to the client device.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
including metadata in the video file that includes at least a validation signature and a source of the video file.

### Claim 4 (depends on 1)

The method of claim 1, further comprising:
including metadata in the video file;
wherein a specialized video player installed on a client device adds user sharing information to the metadata.

### Claim 5 (depends on 1)

The method of claim 1, further comprising:
including metadata in the video file that includes geographical information indicating what geographical areas that the second video may be viewed in;
wherein a specialized video player installed on a client device refers to the geographical information prior to playing the second video in the video file.

### Claim 6 (depends on 1)

The method of claim 1, further comprising:
including metadata in the video file that includes conditional information relating to the second video in the video file;
wherein a specialized video player installed on a client device refers to the conditional information to decide whether to allow or deny playback of the second video in the video file.

### Claim 7 (depends on 1)

The method of claim 1, wherein the first video is a trailer or preview related to the second video.

### Claim 8 (depends on 1)

The method of claim 1, wherein the first video is a standard definition video and the second video is a high-definition version of the standard definition video.

### Claim 9 (depends on 1)

The method of claim 1, wherein the first video is a first portion of an original video and the second video is second portion of the original video.

### Claim 10

A non-transitory computer readable medium storing a program of instructions that is executable by a device to perform a method, the method comprising:
creating a video file having a first content area containing a first video and a second content area containing a second video, the video file formatted according to a first video standard;
encrypting at least a portion of the second video in the second content area, the second video is not viewable using a first video standard player, and the second video is viewable using a specialized video player;
wherein video content in the first content area includes instructions that, when played by the first video standard player, instruct a user on how to download the specialized video player that can access the second video;
storing the video file along with a plurality of video files;
distributing one or more stored video files to client devices.

### Claim 11 (depends on 10)

The non-transitory computer readable medium of claim 10, further comprising:
receiving a request from a client device for a specialized video player;
sending the specialized video player to the client device.

### Claim 12 (depends on 10)

The non-transitory computer readable medium of claim 10, further comprising:
including metadata in the video file;
wherein a specialized video player installed on a client device adds user sharing information to the metadata.

### Claim 13 (depends on 10)

The non-transitory computer readable medium of claim 10, wherein the first video is a trailer or preview related to the second video.

### Claim 14 (depends on 10)

The non-transitory computer readable medium of claim 10, wherein the first video is a standard definition video and the second video is a high-definition version of the standard definition video.

### Claim 15 (depends on 10)

The non-transitory computer readable medium of claim 10, wherein the first video is a first portion of an original video and the second video is second portion of the original video.

### Claim 16

An apparatus, comprising:
a subsystem, implemented at least partially in hardware, that creates a video file having a first content area containing a first video and a second content area containing a second video, the video file formatted according to a first video standard;
a subsystem, implemented at least partially in hardware, that encrypts at least a portion of the second video in the second content area, the second video is not viewable using a first video standard player, and the second video is viewable using a specialized video player;
wherein video content in the first content area includes instructions that, when played by the first video standard player, instruct a user on how to download the specialized video player that can access the second video;
a subsystem, implemented at least partially in hardware, that stores the video file along with a plurality of video files;
a subsystem, implemented at least partially in hardware, that distributes one or more stored video files to client devices.

### Claim 17 (depends on 16)

The apparatus of claim 16, further comprising:
a subsystem, implemented at least partially in hardware, that receives a request from a client device for a specialized video player;
a subsystem, implemented at least partially in hardware, that sends the specialized video player to the client device.

### Claim 18 (depends on 16)

The apparatus of claim 16, further comprising:
a subsystem, implemented at least partially in hardware, that includes metadata in the video file;
wherein a specialized video player installed on a client device adds user sharing information to the metadata.

### Claim 19 (depends on 16)

The apparatus of claim 16, wherein the first video is a standard definition video and the second video is a high-definition version of the standard definition video.

### Claim 20 (depends on 16)
