A digital media mixer includes a plurality of analogue-to-digital converters 201, 202 for converting analogue audio/video signals to digital signals, a plurality of encoders 204, 205 for encoding the digital audio/video signals, a multiplexer 207 for mixing the encoded signals using a format such as MPEG-TS or AVI, and a network interface 208 for transferring the mixed digital audio/video signals by a broadcast or multicast technology. The mixer may further comprise at least one tuner 203 for receiving audio/video signals and tuning the signals based on a requirement signal from a user, and at least one de-multiplexer 206 for resolving the tuned audio/video signals. The resolved signals are mixed with the encoded signals by the multiplexer 207. Tuners 301, 302 may also be provided to tune the analogue audio/video signals based on requirement signals from a user. |
