Abstract
A system and method of generating an output signal includes a receiving system generating a plurality of signals having a first format, an encoder 162 encoding the plurality of signals into a plurality of transport streams and a multiplexer 210. The system also includes a local area network 130 routing the plurality of transport streams to the multiplexer 210 to form a combined signal, a modulator 214 modulating the combined signal to form a modulated signal and a system 202 forming the output signal from the modulated signal. In one aspect, the output signals may be satellite uplink signals.
Claims43
A method of forming an output signal comprising:
- receiving a plurality of signals having a first format;
- encoding the signals to generate a plurality of transport streams, wherein each of the plurality of transport streams comprises audio data and video data;
- after encoding, routing the plurality of transport streams from respective channels of receivers through a local area network to a multiplexer, wherein the multiplexer combines the plurality of transport streams to form a multiplexed signal;
- communicating the multiplexed signal to a transport processing system;
- multiplexing conditional access data, program guide data and the multiplexed signal at the transport processing system to form a combined signal;
- modulating the combined signal to form a modulated signal;
- and
- forming the output signal from the modulated signal.
An apparatus comprising:
- receivers receiving a plurality of signals having a first format;
- a routing system routing the plurality of signals to respective channels of the receivers;
- decoders decoding the plurality of signals and outputting baseband signals;
- encoders generating a plurality of transport streams based on the baseband signals, wherein each of the plurality of transport streams comprises audio data and video data;
- a multiplexer;
- a local area network routing the plurality of transport streams from the respective channels to the multiplexer, wherein the multiplexer combines the plurality of transport streams to form a multiplexed signal;
- a transport processing system in communication with the multiplexer and multiplexing conditional access data, program guide data and the multiplexed signal to form a combined signal;
- and
- a modulator modulating the combined signal to form a modulated signal.
