    摘要： Apparatus and methods for improved software programming interface functionality in a network. In one exemplary embodiment, the network comprises an HFC cable network with CPE in which network-specific programming interfaces (e.g., APIs) may be downloaded to the CPE, registered, authenticated, stored and executed in a software protocol stack implementing OpenCable Application Platform (OCAP) or Multimedia Home Platform (MHP) standards. The host device software comprises a “manager” module that registers APIs identified by the OCAP Monitor Application, such that all applications launched thereafter on the device can use these communications APIs, provided they have the appropriate permission(s). This relieves individual applications from having to support details regarding network-specific protocols and APIs. In an alternate embodiment, class and data files associated with the API functionality are downloaded along with an application. The downloaded application registers the API using a modified version of the API using a description file (DF). The DF describes the class and data files provided with the application that are part of the registered API.

    摘要： 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).

    摘要： 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.
