Abstract:

A system and method for distributing requested content includes a content management system and a device such as a set top box that selects a selection corresponding to content in the content management system and transmits a first material identification to the content management system. The content management system transmits the content to the device with a second material identification associated therewith. The device receives the content and the second material identification and compares the first material identification to the second material identification. When the second material identification corresponds to the content, the device continues downloading the content. When the second material identification does not correspond to the content, downloading of the file is discontinued. A content prefix may also be used alone or in combination with the material identification. The content is prevented from being transmitted if the content prefix does not correspond to the content type.
