摘要： A method of segregating a hybrid fiber cable network involves assigning a packet identifier (PID) to each of a plurality of hubs on the hybrid fiber cable network; assigning a distinct decryption method to each of the plurality of hubs, so that each of the plurality of hubs is identifiable by its associated decryption method and PID; generating selectively multiple encrypted content for transmission to the hubs, where content encrypted for use by each hub is identified by the hub's assigned PID; and transmitting the selectively multiple encrypted content over the hybrid fiber cable network to the plurality of hubs. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： A DRM packager has a programmed processor for receipt of licensing information including a plurality of encryption keys for a corresponding plurality of DRM encryption algorithms and for receipt of content from a content provider. An encrypter encrypts the content under each of the plurality of DRM algorithms to produce multiple DRM selectively encrypted content, where the multiple DRM selectively encrypted content has segments of the specified content that are unencrypted, and selected segments of the content which are duplicated to produce one copy of the selected content for each of the DRM algorithms with each duplicate copy of the selected segments encrypted under a different one of the DRM algorithms, and where the unencrypted segments of content are assembled together with each of the DRM encrypted duplicate selected segments to produce a single unified content assembly that can be played on any of the player devices. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： In certain implementations consistent with the present invention, a method of detecting text in a television video display table involves saving a frame of video to a memory device; determining that the frame of video contains a table having cells containing text; storing a working copy of the frame of video to a memory; isolating text in the table by: removing any table boundaries from the image; removing any cell boundaries from the image; determining if the image has three dimensional or shadow attributes and removing any three dimensional or shadow attributes identified; thereby producing text isolated against a contrasting color background; and processing the isolated text using an optical character recognition (OCR) engine to extract the text as data. 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, an apparatus involves the descrambling of scrambled digital content using a one-time programmable key and digital rights management. The apparatus comprises a processor and a descrambler. The processor is adapted to execute a Digital Rights Management (DRM) function in order to determine whether each entitlement needed to access the digital content is pre-stored. The descrambler is adapted to decrypt encrypted information using a Unique Key stored within the one-time programmable memory. After determining that each entitlement needed to access the digital content is pre-stored, the decrypted information is used to generate a key, which is used to decrypt at least one service key for descrambling the scrambled digital content.

摘要： A method of content substitution involves receiving an ordered stream of packets containing content marked by a first packet identifier (PID) and one or more substitute content portions marked by one or more secondary PIDs, where the number and placement of packets marked by secondary PIDs ahead of packets marked by the first PID in the stream is retained during transmission of the ordered stream of packets; the ordered stream of packets have an odd or even number of packets with the PIDs after a packet with a first PID; initiating processing for display or storage of content contained in packets having the first PID; initiating processing for display or storage of content contained in packets having a selected secondary PID that meets a substitution criterion; and either deleting or processing the content having the first PID depending upon a number of received intervening packets having secondary PIDs that reside between the packets having the first PID and the packets having the selected secondary PID that meets the substitution criterion, where deleting or processing is determined by whether the number of packets is an odd or an even number.
