1. A transport stream encoder, comprising:
- a plurality of buffers coupled to respective sources of component signals, each having a data output terminal for producing component signal data;
a packetizer, having a data input terminal for receiving component signal data, for producing a packet stream; and
a data bus, coupled in common to the respective data output terminals of the plurality of buffers and the data input terminal of the packetizer, for conveying output data from said buffers to said packetizer.

Abstract
A transport stream encoder is disclosed which comprises a plurality of FIFO buffers coupled to sources of component signals. Each of the FIFO buffers has a data output terminal for producing component signal data. A packetizer has a data input terminal for receiving component signal data, and produces a packet stream. A data bus is coupled in common to the data output terminals of the FIFO buffers and the data input terminal of the packetizer.

3. A transport stream encoder, comprising:
-
a plurality of buffers coupled to respective sources of component signals, each having a data output terminal for producing component signal data; a packetizer, having a data input terminal for receiving component signal data, for producing a packet stream; a data bus, coupled in common to the respective data output terminals of the plurality of buffers and the data input terminal of the packetizer, for conveying output data from said buffers to said packetizer; and a scheduler controller, coupled to the plurality of buffers, for selecting one of the plurality of buffers to supply component signal data at its data output terminal to the packetizer to produce a packet;
whereinsaid buffers are FIFO buffers; each one of the plurality of buffers has a further output terminal for producing a full signal indicating whether the one of the plurality of FIFO buffers contains sufficient data to produce a packet; and the scheduler controller selects the one of the plurality of buffers to produce component signal data at its data output terminal in response to the respective full signals from the plurality of buffers. - View Dependent Claims (4)
