  • Publication number: 20100313226
    Abstract: Methods and apparatus for content, media and data delivery and access between devices of a premises and one or more portable media devices. In one embodiment, the apparatus comprises a media bridge between a portable media device (PMD) and a user's home network and/or home devices (e.g., set-top boxes, DVRs, etc.)). The apparatus is adapted to convert content stored on a PMD to a format capable of being rendered on a home device which may then store or playback the content. Control of the presentation is also provided by the bridging apparatus. The apparatus may also be adapted to transfer content from the home device to the PMD for storage or playback. In another embodiment, the apparatus may function within a home network having a trusted domain to provide content between a plurality devices on the network (and in the domain) and the PMD.

  • Publication number: 20100020794
    Abstract: 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.

  • Publication number: 20090248794
    Abstract: A video content system includes a head end server module and a content-sharing server coupled to a video content network. Also included is a converged premises gateway module coupled to the video content network at a location remote from the head end server module and the content-sharing server. The converged premises gateway module includes a processor and a video content network interface coupled to the processor and the video content network and configured for communication with the head end server module over the video content network. The gateway module also includes a memory module having a predetermined storage location for content to be shared with the content-sharing server and a local area network configured at least for distribution of video content within the remote location. The system further includes an upload module configured to cause the content in the predetermined storage location to be uploaded to the content-sharing server.

  • Publication number: 20090207866
    Abstract: Methods and apparatus for utilizing bitrate or other data associated with statistically multiplexed video (e.g., programs) or other content within a network to ensure quality of service (QoS) at a subscriber premises or local network. In one embodiment, the present invention provides improved multiplexing apparatus and methods that allow a consumer premises device to obtain QoS data and employ that data to enforce and maintain one or more QoS policies. In another embodiment of the present invention, an improved consumer premises device is provided which is adapted to receive a multiplexed program stream and subsequently demultiplex and time stamp the resulting single program streams. The time stamps are then utilized to generate QoS data which is utilized to enforce and maintain a QoS policy. Business methods associated with the various features described above are also disclosed.

  • Publication number: 20090210912
    Abstract: Apparatus and methods for enhanced tuner efficiency, wherein tuner resources function to permit multiple content streams to be demultiplexed and thus made available for subsequent display. In one embodiment, Customer Premises Equipment (CPE) comprises a resource manager on which a guide application is run to control the tuning of an available tuner resource. This approach obviate reliance on OCAP or other proprietary vendor architecture applications. In another variant, the CPE is adapted to receive RF source data from a wideband tuner, or multiple tuners. The CPE may also be utilized in conjunction with other system configurations designed to enforce a security or other policies within a premises network. The CPE may also employ ‘look ahead’ capabilities to anticipate a QAM stream content before it is received.

  • Publication number: 20080313691
    Abstract: Apparatus and methods for premises gateway functions that integrate or unify functions typically distributed across multiple devices within a content-based network. In one embodiment, the out-of-band (OOB) signaling functionality normally provided in each of a set-top-box (STB) and digital video recorder (DVR) are unified into a common OOB (e.g., DOCSIS) capable premises gateway device, thereby obviating OOB tuners and related components from each device. In another variant, the premises gateway is adapted for all-IP operation, such as for use with IP-based computers and IP set-top boxes, etc. Fully unified variants are also disclosed, wherein the DVR and/or STB functions are physically integrated within the premises gateway.

  • Publication number: 20080247541
    Abstract: 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.

  • Publication number: 20080112405
    Abstract: Apparatus and methods for protected content access, browsing and transfer over a network. In one embodiment, the network comprises a premises (e.g., residential) LAN, and the apparatus comprises a server and renderer consumer premise equipment (CPE). The renderer CPE scans the network to search for a server CPE that implement a compatible security framework. The renderer authenticates itself with the server, and the server allows content browsing and selection access only to an authorized and authenticated renderer. A negotiation and exchange protocol comprises messages exchanged between the renderer and the server that include one or more of device identification, encryption key exchange, digital certificates and information regarding security package used by each CPE.

  • Publication number: 20060203844
    Abstract: In optical telecommunications networks using passive optical networks (PON), an optical wavelength band called the enhancement band (1539 to 1565 nm) is typically used to carry broadcast video signals in either analog television or QAM Digital Video form. This enhancement band is used here to carry a unidirectional baseband Ethernet signal, such as Gigabit Ethernet, in the optical domain to all or a subset of subscriber premises to carry broadband services from, for instance, a video on demand distribution facility. This results in a network with all digital baseband signaling and simplifies the network architecture so as to be all Internet Protocol and/or all Ethernet compatible.
