    摘要： In one implementation a method of authenticating the installation of a television receiver involves generating a fingerprint value as function of the television network characteristics at an authorized installation location, where the fingerprint is a function of at least one of a gain value of a variable gain amplifier and an equalizer coefficient of an adaptive equalizer of the television appliance; receiving a code that is a function of both a decryption key and the fingerprint value from a broadcast source; ascertaining a value of the decryption key by applying an inverse function to the code that produces the decryption key as an output; and carrying out a decryption process at the television receiver appliance using the decryption key. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

    摘要： A selective encryption encoder consistent with certain embodiments of the invention has a packet identifier that identifies packets of a specified packet type, the specified packet type being defined by packets occurring in a star pattern approximately situated at an upper center of an image which contain intra-coded macroblocks. A packet duplicator duplicates the identified packets to produce first and second sets of the identified packets. The packets are sent to and from a primary encryption encoder to encrypt the first set of identified packets under a first encryption method. A secondary encrypter encrypts the second set of identified packets under a second encryption method.

    摘要： A selective encryption encoder and method of dual selective encryption and detection of intra-coded slices in video content. The selective encryption encoder has a packet identifier that identifies packets of at least one specified packet type, the at least one specified packet type being packets in a set of N consecutive slices in a frame wherein the a second byte after a slice start code is identical in all N consecutive slices. A packet duplicator duplicates the identified packets to produce first and second sets of the identified packets. The packets are sent to and from a primary encryption encoder to encrypt the first set of identified packets under a first encryption method. A secondary encrypter encrypts the second set of identified packets under a second encryption method.
