摘要： Flexible systems and methods are disclosed that may be used for provisioning, configuring, and controlling a host embodied in a cable set top box or other digital device attached to a digital communication network, such as cable distribution network. An enhanced services system maintains various host files for various types of hosts that a cable subscriber may purchase and connect to the cable network. The Enhanced Services Server interacts with the host using the host files. The host files may be downloaded from the host manufacturer into a database that distributes the modules as required to the various enhanced services systems. The host may be purchased by the cable subscriber and provisioning may be initiated by the retailer at the time of purchase using a provisioning network interacting with the appropriate cable system serving the subscriber. This abstract is not intended to limit or construe the scope of the claims.

摘要： In one embodiment, a transaction server facilitates a purchase transaction for goods or services between users at two mobile phones. The Purchaser initiates a request for a purchase transaction to a server, and is provided with a unique code (“purchasing nonce”) that is uniquely associated with the request. The user of the first mobile phone provides the purchasing nonce to the Seller, who enters that value into the selling mobile phone. The selling mobile phone initiates a request to join the transaction as identified by the purchasing nonce. After confirmation of the Purchaser that the Seller can join the transaction, the Seller can itemize the goods for sale, which are electronically presented to the Purchaser for approval. After all items are selected, the Purchaser approves the transaction, and the transaction server can then transfers funds. An electronic receipt is provided to the Purchaser's mobile phone for confirmation.

摘要： An intrusion protection system is disclosed for an Internet based television service (IPTV) that detects unexpected conditions, including rogue terminals sending unexpected message. The system comprises one or more firewalls that may implement a mirrored state machine which is specific to an application level protocol. The state machine is typically maintained for each user, and each message from a user may be analyzed to determine if it is an expected message. The message may also be analyzed to determine if it represents an unusual volume of messages from the user or otherwise represents some other unusual aspect associated with a rogue terminal or terminals. Information regarding unusual events are reported from the firewall to an intrusion protection system which can further analyze the events, other data, and report possible attacks to a network operations center.

摘要： A multi-stage recursive sample rate converter (“SRC”) typically embodied as digital signal processor provides for an efficient structure for converting digital audio samples at one frequency, such as 48 kHz, to another frequency, such as 44.1 kHz. A parameter codebook comprising memory stores parameters used at a plurality of stages by the SRC. For each stage, a controller coordinates the SRC to use the appropriate set of parameters from the codebook, process an input audio sample stream, and store the intermediate results in a buffer. The controller then causes the intermediate results to be processed again as input to the SRC in a subsequent stage of processing using a different set of parameters. The process is repeated until all stages are completed, and the final results are the output digital audio data stream at the desired sampling rate.

摘要： A multiplexer handling different types of traffic in different queue types, including in one embodiment time-stamped content such as in the form of MPEG service data, untimed content such as in the form of other variable bit rate data, and periodic tables, such as in the form of MPEG program specific information, allocates a tag to each packet, which is used to schedule packets for transmission. A tagging algorithm tags each packet in the queue, and a packet scheduling algorithm uses the tag to determine which packet is next to be transmitted, and a control algorithm determines when the scheduling algorithm will be executed. The algorithms cooperate to allow the multiplexer to handle traffic without requiring an internal clock to be synchronized with the input streams, nor stuffing of packets to pad out the contents of the variable bit rate traffic.

摘要： A system and method for processing multiple client flows to a single outbound link is provided. Specifically, a scheduler enforces a maximum symbol rate on the aggregate output flow. Inbound client flows are scheduled for output based upon individual quality of service parameters. For each round of scheduling, packets configured for a first bandwidth range are processed in a first pass and packets configured for a second bandwidth range are processed in a second pass. The packets are placed into frames before transmission. A comparison of the actual symbol usage with the estimated symbol is made and used to determine how to schedule inbound client flows for the second pass of the round.

摘要： A system and method is disclosed allowing a cable network provider to dynamically allocate a network resource, in the form of channel bandwidth, for conveying either analog or digital assets. Certain assets are distributed in a cable network in an analog manner but only during certain time periods. The network resources could be used for offering digital services at other times. A programmable RF switch allows network resources to be switched to convey digital assets when the analog channels are not required. The digital assets conveyed may comprise movies, games, or music and can be transferred during ‘off-hours’ for local storage in the set top box in anticipation of future requests by a user. When the asset is requested, the set top box first checks if the asset is locally available, and if so, spools it out locally.

摘要： A video on-demand (“VOD”) system receives a request for a VOD program, thereby generating a VOD session for the viewer. The VOD system generates a dynamic playlist incorporating at least one advertisement, where the playlist is provided to the VOD server, causing said VOD server to stream the playlist to the viewer. Upon suspension of viewing the VOD program by the viewer, the VOD system terminates the VOD session. Upon receiving a subsequent request from the viewer for the same VOD program, a second VOD session is established by the VOD system with a second dynamic playlist incorporating at least one other advertisement. The VOD system streams the program beginning at the same point in the program where the original interruption occurred.
