    摘要： Various embodiments of apparatus and/or methods are described for skipping, filtering and/or replacing content from an audio/video stream using text data associated with the audio/video stream. The text data is processed using location information that references a segment of the text data of the first audio/video stream to identify a location within the first audio/video stream. The location within the first audio/video stream is utilized to identify portions of the audio/video stream that are to be skipped during presentation. The portions of the audio/video stream that are to be skipped are filtered from the audio/video stream, and some of the skipped portions of the audio/video stream are replaced with substitute content. The filtered video stream, including the substitute content, is outputted for presentation to a user.

    摘要： A system for securely providing adaptive bit rate streaming media content on-demand may include a security sever of a program distributor that selects, based on a received authorized request, which of a differently encrypted stored versions of a “special segment” of the requested program to deliver to the receiving device during the transmission of the requested program. The selection may be based on a pseudo-random selection process per request for the program based on an identifier of the request associated with the remote control device. The selection of which of the differently encrypted stored versions of the “special segment” of the ordered program to deliver may be=based on the current session. The secure remote then sends to the receiving device the correct decryption key for the receiving device to decrypt the particular encrypted version selected of the “special segment” to be sent to the receiving device.

    摘要： One embodiment takes the form of a method and apparatus for creating a customer-specific encryption key for encrypting digital information. The encryption key may be based on a customer number and may be associated with several devices such that the devices may encrypt and decrypt the digital information. Because each device may have the same encryption key, the encrypted data may be encrypted by a first device, transferred from the first device to a second device and decrypted and read by the second device. Thus, encrypted digital information may be shared between devices that generate a customer-specific encryption key from a common customer number. In one embodiment, the customer-specific encryption key may be utilized by a set-top box of a television system to encrypt and decrypt a digitally recorded television program.

    摘要： Content receivers may simultaneously record multiple instances of content for multiple programming channels based on content provider instructions. Systems and methods utilize the content receivers to record these multiple instances from at least a single transponder. in some instances, multiple transponders may have a common control word so that content carried on each such transponder may be simultaneously received, decoded and recorded, Further, a single demodulator may be associated with multiple tuners, so that the single demodulator processes all content received from transponders with common control words and/or other encryption mechanisms.
