Definitions

  • TECHNICAL FIELD This invention relates to a technique for replacing at least a portion (e.g., a scene) in content, such as a movie or television program, with an alternative scene.
  • content providers often maintain two versions of the same content (e.g., a television show or movie under a particular title) , one for restricted distribution (e.g., adults) and the other for unrestricted distribution.
  • restricted distribution e.g., adults
  • unrestricted distribution e.g., adults
  • content distributors typically will distribute both the restricted and unrestricted versions of the same content contemporaneously, thus requiring two different channels, each carrying a separate one of the two content versions.
  • the need for additional channels increases transmission bandwidth and consequently incurs higher costs.
  • a method for automatic scene replacement in content commences by detecting for at least one scene in the content whether objectionable subject matter is present according to at least one received criterion identifying objectionable subject matter. If a scene having objectionable subject matter is detected, that scene is replaced with an alternative scene having subject matter not deemed objectionable according to the at least one criteria.

  • the set-top box 10 accomplishes such scene replacement using well-known V- chip technology now mandatory in present day television sets and set-top boxes to restrict viewing based on age ratings. Very often, only a short scene in a movie or television program violates a particular age rating, thus restricting viewing of the entire movie by a general audience.
  • the automatic scene replacement of the present principles advantageously allow a content provider to distribute a single copy of content (e.g., a movie or television program) knowing that scenes deemed objectionable for certain audiences will undergo replacement with alternative scenes to render the content suitable for viewing by such restricted audiences.

  • Digital television receivers shall react in a similar manner as analog televisions when programmed to block specific rating categories. Effective March 15, 2006, digital television receivers will receive program rating descriptors transmitted pursuant to industry standard EIA/CEA -766-A "U.S. and Canadian Region Rating Tables (RRT) and Content Advisory Descriptors for Transport of Content Advisory Information using ATSC A/65-A Program and System Information Protocol (PSIP)," 2001 (incorporated by reference, see ⁇ 15.38). Blocking of programs shall occur when a program rating is received that meets the pre-determined user requirements.
