ABSTRACT:
A CableCARD device for manipulation of a stream of data has an inband data input for receiving a stream of video data from a host, the stream of video data being encrypted and encoded according to a first coding. A decrypter decrypts the encrypted data. A transcoder transcodes the stream of video data to convert the stream of video data to a second coding, producing a transcoded data stream. An encrypter encrypts the transcoded data stream. An inband data output sends the encrypted transcoded data stream back to the host. This abstract should not be considered limiting, since other embodiments may incorporate more, fewer or different elements that those described in this abstract.
