Techniques to remotely monitor and control operations performed by one or more head-ends (or servers) in an information distribution system. In one implementation, a monitor and control unit communicates with various elements (e.g., an IPG service manager and a session manager) within each head-end to receive information relating to the operations of the head-end. This information may include status and/or indications of possible error conditions relating to (1) various operations (e.g., encoding, multiplexing, and so on) performed by the head-end, and (2) the transport streams being transmitted from the head-end. The received information may then be forwarded to one or more remote devices (e.g., pagers, cellular phones, PDAs) designated to receive the information. Response messages may also be received from the remote devices and forwarded to the appropriate head-end, which may adjust its operation as indicated by commands included in the messages.

Remote monitoring and control method and apparatus for an information distribution system

Systems and methods to dynamically convert Web content to an interactive program for display on resource constrained television clients are described. In particular, a head-end server in a digital television entertainment system downloads the Web content from an external data source. The head-end server dynamically transcodes the downloaded content into an interactive walled garden program (iWGP) that includes MPEG stills and metadata for delivery to a client in the television entertainment system.

Systems and methods for dynamic conversion of web content to an interactive walled garden program

A system for delivering interactive program guide (IPG) includes a number of encoding units, at least one transport stream generator, and a session manager. The encoding units encode a number of IPG pages and generate a number of (e.g., guide, video, audio, and data) streams, with each stream being assigned a respective packet identifier (PID). Each transport stream generator receives and multiplexes selected ones of the streams from one or more encoding units into one or more transport streams. The session manager directs each transport stream generator to generate one or more transport streams based on usage. The system may further include a bandwidth manager that monitors usage and reports the usage to the session manager. The encoding units can be operated to encode only once each IPG page to be transmitted. Each transport stream generator can be operated to provide differentiated IPG for the neighborhood being served by the transport stream generator. The number of transport streams generated by each transport stream generator can be dynamically adjusted based on demands from the neighborhood being served by the transport stream generator. Each transport stream generator can be directed to generate an additional transport stream if usage exceeds the capacity of the currently transmitted transport streams.

Method and systems for multicast using multiple transport streams

Techniques to monitor operation of an information distribution system and delivery of programming, guide data, and other information by the system. These techniques may be used for diagnostics, quality control, and other purposes, and for various types of systems. In accordance with one method, a directive is received to monitor a particular channel at a particular terminal. In response to the received directive, a command is sent (e.g., via a remote control unit) to the terminal. Contents are then received from the terminal, captured, and reported. The reported contents may be used to visually verify the contents being delivered to the terminals, check what the viewers may observe, mimic and test interactive experiences of the viewers, observe actual viewing conditions at the terminals, and perform other tests and diagnostics. The received contents may be captured as one or more video frames, as a video sequence, or in some other format.
