The client device uses information regarding the chunks to generate a local manifest file, which it then uses to reconstruct the media stream. A video client may also dynamically insert and account for updated secondary content (such as advertisements) during each playback instance, thus enabling the service provider to realize commercial opportunities which were previously not possible. Various operational/business rules are also disclosed for e.g., enabling and disabling functions with respect to playback of the content.

A content delivery resource in a cable network receives a request for specified content. The content delivery resource retrieves profile information assigned to the subscriber domain. The profile information indicates multiple different playback formats assigned to the subscriber domain. To service the request, the content delivery resource utilizes the profile information associated with the subscriber domain to select versions of the specified content encoded in accordance with the multiple different playback formats. The content delivery resource then initiates transmission of the versions of the specified content in the multiple different playback formats to the subscriber domain for playback on multiple types of playback devices.
A wireless access point employs a wireless configuration database for retrieving a stored wireless profile corresponding to a subscriber device from a remote location that enables the user to establish an Internet connection using their subscriber device with the same network identifiers and settings employed from the home wireless profile. The network identifier is typically an SSID (Service Set Identification), and labels the wireless configuration using a mnemonic name familiar to the user. The wireless configuration also denotes authentication and security (passphrase) tokens required for access, and would therefore enable the user to sign on at the remote wireless access point using the passphrase already known from their home WiFi arrangement. Subsequent attempts automatically establishing a connection to the subscriber device upon detection and authentication using the retrieved wireless profile without broadcasting an open SSID receivable by other wireless devices within range.
Techniques disclosed herein include systems and methods for providing active mobility of Wi-Fi enabled devices within a given wireless local area network (WLAN).

METHODS AND APPARATUS FOR SELECTING DIGITAL TECHNOLOGY FOR PROGRAMMING AND DATA DELIVERY
Methods and apparatus for selecting digital technology for programming and data ~ delivery over, e.g., a content-based network. In one embodiment, the network comprises an HFC cable or satellite network that includes a server process interfacing with a plurality of customer premises equipment (CPE), and/or associated client devices, each having different capabilities profiles. The server determines the one or more capabilities possessed by the CPE, and evaluates one or more program or content choices for possible delivery to that CPE based on its profile. The server generates a list of programs or content based on this evaluation, and transmits this list to the CPE, which displays the list for viewing by a user. The user is therefore offered a list of available content that is compatible with their specific configuration. A business and operational rules engine is also optionally employed to control the operation of the foregoing processes to accomplish particular business or operational goals.
Methods and apparatus for assigning physical channels in a content-based network. In an exemplary embodiment, the network comprises a cable television network having a plurality of cable modems, and the physical channels are assigned to the cable modems based at least in part on any multicast transmissions that may exist on the system. When two cable modems are receiving the same multicast transmission, the invention causes tuning of one or more of the cable modems to the same physical channel in order to limit the total number multicast transmissions on the network. Multicast transmissions typically comprise video or audio information, but other types of information may also be multicast according to the invention. In another embodiment, a multicast transmission list (containing a list of multicast transmissions and the corresponding physical channels) is sent to the set of cable modems. This list is used by the modems (or associated CPE) to manage channel allocation and tuning.
Methods and apparatus for dynamically and automatically allocating network resources through anticipatory analysis and control. In an exemplary embodiment, the network comprises a broadcast switched digital architecture, and network bandwidth allocation to multiple digital program streams is performed by processing historical user tuning data, which is obtained directly from the subscriber's consumer premises equipment (e.g., DSTB). When an increase or decrease in bandwidth required to support certain programs is anticipated, network resource re-allocation is performed automatically by a software process running on the switching server. In this fashion, speculative but "intelligent" projections of bandwidth and program stream requirements can be made automatically by the server software, without operator intervention. The server also optionally dictates the optimal monitoring and data collection parameters to the DSTB.

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.

H04N 21/266 - Channel or content management, e.g. generation and management of keys and entitlement messages in a conditional access system or merging a VOD unicast channel into a multicast channel
The present invention teaches methods and systems for blocking unauthorized access to cable modem configuration files stored on trivial file transfer protocol (TFTP) servers. Filenames are modified by the DHCP to incorporate an authentication key (and optional cloaking) prior to transmission to the cable modem. When the TFTP server receives a modified filename, it also generates an authentication key. The authentication keys must match in order for the cable modem to receive the configuration file requested. At a minimum, authentication keys depend upon the un-modified filename, the cable modem IP address and a "coordination pass phrase" known to the TFTP server and DHCP server, but not known to the cable modem. Variations include optional cloaking, various actions performed for non-matching authentication keys, selection of authentication key generating algorithm and inclusion of cable modem MAC address in the authentication key for all cable modems or for premium service customer cable modems.
