20080247541 | METHODS AND APPARATUS FOR CONNECTING A CABLE NETWORK TO OTHER NETWORK AND/OR DEVICES - Methods and apparatus for connecting, e.g., bridging, a cable network to other networks and/or devices is described. A bridge device facilitates the distribution of cable provider content to end users operating IP based devices. The bridge device performs one of more of the following: interface protocol conversions, user device controlled tuner selection, transcoding of data, transrating of a data stream, decryption in accordance with a conditional access protocol and re-encryption in accordance with an authorized service domain protocol. | 10-09-2008 |
20100020794 | METHODS AND APPARATUS FOR USING TUNERS EFFICIENTLY FOR DELIVERING ONE OR MORE PROGRAMS - In response to user requests for content, content may be dynamically mapped to communications channels, e.g., QAM channels, used to communicate multiple programs during the same transmission time slot, e.g., through the use of multiplexed MPEG streams. A customer premise device, e.g., STB, uses a tuner tuned to the QAM channel to receive the communicated stream, recovers multiple programs communicated using the single communications channel, and records and/or displays the recovered programs. In this manner, more programs can be received and recorded than there are tuners in the customer premise device, e.g., STB. In some embodiments a content service provider control node processes user requests for content, maps requested programs to transport streams, communicates mapping decision information to a content distribution node, and communicates QAM tuning information to the user devices which can then receive and record multiple programs communicated via a single communications channel. In some embodiments a customer premise device utilizes program information to direct demultiplexed program channels to local or remote recorders (for storing) or decoders (for playback). | 01-28-2010 |
20100245669 | TECHNIQUE FOR EFFECTIVELY UTILIZING LIMITED BANDWIDTH OF A COMMUNICATIONS NETWORK TO DELIVER PROGRAMMING CONTENT - To effectively utilize the bandwidth of a cable TV network, which is limited, analog TV program material is digitized and compressed before its transmission over the network. The resulting signals consume only part of the analog TV band traditionally needed for transmission of the analog TV program material. The newly available bandwidth in the analog TV band may be utilized for other cable TV services, e.g., video-on-demand (VOD) services. A reception gateway is employed at a user location to frequency-translate any VOD signals, transmitted through the analog TV band, to another frequency band, thereby avoiding disturbing the normal operation of a set-top terminal in receiving the analog TV program material through the analog TV band at the user location. | 09-30-2010 |
20100251288 | TECHNIQUE FOR DELIVERING ENTERTAINMENT PROGRAMMING CONTENT INCLUDING COMMERCIAL CONTENT THEREIN OVER A COMMUNICATIONS NETWORK - Although personal video recorders (also known as digital video recorders) provide certain conveniences to viewers of programming content, such devices facilitate manipulation or Askipping@ of commercials, frustrating the intent of the advertisers of the commercials.

The duration of the alternate commercial(s) corresponds to the duration of the original commercial at the fast-forward (rewind) speed controlled by the user. With the invention, the user advantageously realizes the convenience of manipulating programming content, and at the same time can appreciate the full impression of an alternate commercial to the original commercial, albeit in a shorter duration. | 09-30-2010 |

20130070922 | TECHNIQUE FOR SECURELY COMMUNICATING AND STORING PROGRAMMING MATERIAL IN A TRUSTED DOMAIN - A “trusted domain” is established within which content received from a communications network, e.g., a cable TV network, is protected from unauthorized copying thereof, in accordance with the invention. In an illustrative embodiment, the trusted domain includes a device associated with a user which receives content from the cable TV network. The content may be encrypted using a content key in accordance, e.g., with a 3DES encryption algorithm before it is stored in the device. In addition, a first encrypted content key version and a second encrypted content key version are generated by respectively encrypting the content key with a public key associated with the device and another public key associated with the user, in accordance with public key cryptography. The first and second encrypted content key versions are stored in association with the encrypted content in the device storage. The encrypted content can be migrated from a first device to a second device, and can be decrypted in the second device in the second device is associated with the same user, and also provided with the second encrypted content key version. | 03-21-2013 |
20130104162 | TECHNIQUE FOR SECURELY COMMUNICATING PROGRAMMING CONTENT - A technique is provided for securely transferring programming content from a first device in a first layer, e.g., a trusted domain, to a second device in a second layer, e.g., outside the trusted domain. When a user requests that the first device transfer protected content to the second device, the first device needs to authenticate the second device. After the second device is authenticated, the first device may transfer to the second device the protected content, together with a rights file associated therewith. The rights file specifies the rights of the second device to use the protected content, according to its security level indicative of its security. These rights may concern, e.g., the number of times that the second device may subsequently transfer the protected content to other devices, the time period within which the second device may play the protected content, etc. The higher the security level of the second device is, the more rights accorded thereto. Indeed, the second device may need to meet a minimum security level requirement in order for it to receive or keep the protected content. | 04-25-2013 |
