The encrypted packets are of at least one selected packet type and the at least one selected packet type has at least one of the following: packets containing a video slice header appearing in an active region of a video frame, any packet carrying data describing an active region of a video frame, I Frame packets, packets containing motion vectors in a first P frame following an I Frame, packets having an intra_slice_flag indicator set, packets having an intra_slice indicator set, packets containing an intra_coded macroblock, packets that carry data for a slice containing an intra_coded macroblock, packets containing data from a first macroblock following the video slice header, packets containing video slice headers, packets containing anchor data, and P Frame packets for progressively refreshed video data. A decrypter decrypts the encrypted packets; and a decoder decodes the unencrypted packets and the decrypted packets to produce a signal suitable for play on a television set. This abstract is not to be considered limiting since other embodiments can include more, fewer or different features than those described in this abstract.

摘要： An HDMI parental control device consistent with certain embodiments has an HDMI receiver that receives an HDMI audio/video stream and produces editable audio/video output data and a logic processor that receives closed caption data and compares descriptors in the closed caption data with a list of descriptors to be censored. When the logic processor detects a descriptor to be censored it causes the audio/video data corresponding to the descriptor to be censored to be altered from the audio/video output data to produce censored audio/video output data and uncensored audio/video output data and then output via an HDMI transmitter. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： According to one embodiment of the invention, the descrambler IC comprises a local memory to store a unique key and a plurality of process blocks. A first process block performs cryptographic operations on a first mating key generator using the unique key in order to produce a first key. A second process block uses the first key to perform cryptographic operations on a second mating key generator in order to produce a second key. Using the first key and the second key, a third process block decrypts a first encrypted descrambling key in order to recover a first descrambling key and a fourth process block decrypts a second encrypted descrambling key to recover a second descrambling key. The descrambler IC includes a descrambler to descramble the scrambled digital content using both the first descrambling key and the second descrambling key in order to produce digital content in a clear format.

摘要： One embodiment of the invention relates to an apparatus comprising an input, a descrambler unit and a re-scrambler unit. The input is adapted to receive scrambled content. The descrambler unit is coupled to the input. The descrambler unit descrambles the scrambled content in order to recover unscrambled content and concurrently routes both the unscrambled content over a first communication link for display on a display device and the unscrambled content over a second communication link. The re-scrambler unit is coupled to the second communication link. The re-scrambler unit is adapted to scramble the unscrambled content to produce re-scrambled content for transmission.

摘要： A method of encrypting a digital television signal carried out in any operative order involves duplicating packets in the digital television signal so as to create first and second duplicate packets; encrypting the first duplicate packets according to a first encryption method to create first encrypted packets; encrypting the second duplicate packets according to a second encryption method to create second encrypted packets; identifying packets in the digital television signal that are of a packet type, while other packets are not of the packet type; replacing the identified packets in the digital television signal with corresponding first and second encrypted packets to produce a multiple partially encrypted digital television signal comprising the other packets that are unencrypted and the first and second encrypted packets; and distributing the multiple partially encrypted digital television signal. This abstract is not to be considered limiting as other embodiments may include more or fewer or differing elements than appear in the abstract.
