摘要:
An apparatus for increasing the functionality of a set top converter for use with a program delivery system comprises a circuit card electronically connected to a set top converter. Information and data are passed between the circuit card and the set top converter. The circuit card includes means for generating menus which identify programs and channels, means for sequencing through menus; and means for selecting a program or channel through the generated menus in response to a user command.

Systems and methods for de-combining a single combined data stream into a plurality of original data streams, where each original data stream has its own timing information, and passing respective original data steams to, e.g., one or more DVB-T modulators for broadcast into, e.g., a single frequency network. The original data streams and the single combined data stream may be, e.g., MPEG-compliant data streams.

Systems and methods for combining a plurality of transport streams into a single transport stream for transmission to, e.g., a single frequency network via a satellite. Embodiments provide receiving a plurality of original, e.g., MPEG-compliant, data streams, where each original data stream has its own timing information, combining the plurality of original data streams into a single combined data stream which is also, e.g., MPEG compliant, modulating the single combined data stream for uplink to a satellite, receiving a downlink transmission from the satellite, where the downlink transmission includes the single combined data stream, de-combining the single combined data stream into the plurality of original data streams, and passing respective original data steams to, e.g., one or more DVB-T modulators for broadcast into a single frequency network.

A method is provided to e.g. target virtual objects to subscribers, comprising the following steps:
receiving an interactive virtual object at a reception site; selecting the interactive virtual object by a user; sending an interactive request related to the interactive virtual object to a second site remote from the reception site; and receiving a response from the second site at the reception site.

A packet transmitter for transmitting, in the form of a packet, a transmission unit including a data sequence which comprises fixed length blocks formed by dividing predetermined data and to each of which block information representing the type of block is added. A DIF data processing circuit (104) eliminates predetermined redundant information from block information belonging to a plurality of blocks in accordance with an inputted data sequence, generates a transmission header having a new identifier, and generates a transmission unit having the generated transmission header. Then, a transmission terminal (102) transmits the generated transmission unit through a transmission line. At this time, the DIF data processing circuit (104) generates a new identifier by permitting a predetermined set of block information to represent a plurality of sets of block information and generates a transmission header having the generated identifier, or permits one set of block information to represent the same block information, or eliminates redundant information which includes at least one of preliminary data and invalid data.

A method of delivering video over a network (fig. 1) includes separating the digitally compressed video signal into multiple sub-signals (fig. 1, item 21), coding each of the sub-signal (fig.1, item 20), transmitting each of the sub-signals over asynchronous transfer mode paths (fig. 1, item 10), receiving each sub-signals (fig. 1, item 22), and selecting certain of the sub-signals according to a bandwidth suitable for subsequent reception over a digital subscriber line path (fig. 1, item 12). Preferably, the step of combining selectie ones of the sub-signals is based on a data rate capacity of the digital subscriber line path (fig. 1, item 12) for subsequent transmission. the bandwidth of the sub-signals selected is supported by the data rate of the digital subscriber line path.
