A method for seamlessly splicing a local commercial segment into an existing network time slot, without decoder buffer overflow or underflow. The vbv_delay of the commercial segment is manipulated (e.g., for a minimum delay or a maximum delay). The pictures from the commercial segment are output for at least a portion of the associated network time slot duration. A determination is made regarding the number of pictures remaining in a stored portion of the incoming network feed or the commercial segment and the output rate is adjusted as required. The vbv_delay of the stored network feed or the vbv_delay of the local commercial segment is adjusted to match the vbv_delay of the incoming network feed.

Splicing compressed, local video segments into fixed time slots in a network feed

A method and apparatus for providing a composite of stored dynamic background activities with newly filmed or captured live foreground activities, thereby providing a real-time and on-site guide to actors and directors.

Apparatus and method for producing images using digitally stored dynamic background sets

A system and method for generating a transport packet stream having an output formatted as an ASI group having a plurality of short and long ASI packets in a fixed sequence. The short and long ASI packet each have an associated transport packet and a fixed number of special idle characters and the transport packets are dispersed among the special idle characters.

Single clock reference for compressed domain processing systems with interspersed transport packets

A device and method for utilizing a single clock signal to generate a digital data stream signal for transmission in a compressed domain transmission system. The device includes a plurality of packetized elementary stream encoders electronically coupled to a transport stream encoder electronically coupled to an output interface adapted to generate the digital data stream signal. The method includes: operating each of the packetized elementary stream encoders responsively to the single clock sequence to generate a plurality of packetized elementary stream signals; operating the transport stream encoder responsively to the single clock signal to form a transport stream signal from the plurality of packetized elementary stream signals, wherein the transport stream signal includes a plurality of data packets each formed using the transport stream encoder and select ones of the plurality of data packets formed by the transport stream encoder include synchronization data; and, operating the output interface responsively to the single clock reference to output the digital data stream signal in compliance with an predefined manner.

Single clock reference for compressed domain processing systems

In a compressed domain digital communications system, a method for reducing a variable latency associated with a buffer and at least partially resulting from at least one splice between a FROM bitstream and a TO bitstream each including data corresponding to a plurality of frames, the method including: selectively deleting data corresponding to a select at least one of the frames from the buffer based upon the variable latency so as to reduce the variable latency when an amount of data corresponding to a number of frames present in the buffer is greater than a given number of frames; and, regulating a flow of data in the system to prevent an underflow condition in the system by effecting a repeat last frame command and prevent an overflow condition in the system by slowing a rate of transmission for the data associated with at least one of the frames in the TO bitstream.

Flow control, latency control, and bitrate conversions in a timing correction and frame synchronization apparatus

An apparatus and method for receiving a bitstream containing timing information and respective program information, the program information is processed and associated with locally generated timing information to form an output bitstream, the locally generated timing information is synchronized to the received timing information so that the timing relationships of the received program information are preserved even after the program information is processed.

Method and apparatus for time base recovery and processing

An apparatus and method for receiving an information stream comprising a plurality of timing portions and associated payload portions, decoding each timing portion, determining a duration parameter of a payload portion associated with the decoded timing portion, and recoding the timing portion using the duration parameter and a local reference time parameter.

Synchronizing a packetized digital datastream to an output processor in

A transmission processor (16) receives an input packetized datastream (FIGS. 6-9; FIGS. 15-18 signal A) containing packets of data bytes including MPEG coded video information. The transmission processor outputs a symbol datastream (FIGS. 15-18 signal F) representing a sequence of data fields (FIG. 1) comprising groups of data segments (X) with an associated field sync segment. The transmission processor inserts overhead information. e.g., FEC error coding information, into each data segment, and inserts the longer duration field sync overhead segment between groups of data field segments. The frequency of the transmission processor input byte clock (SC/2, FIG. 6; FIG. 15) an integer sub-multiple of an output symbol clock (SC) frequency. The input datastream exhibits constant uniform inter-packet data gaps and a constant uniform data rate, thereby facilitating the seamless insertion of the field sync overhead segment into the datastream without interrupting the datastream. Similar but inverse processing occurs at a receiver.
