THE DIGITAL microwave systems company is showcasing its Nucomm Newscoder 4 video/audio encoder and RF Central microLite HD Elite
video RF link. The Newscoder 4 is an HD/SD video/audio encoder with AES Encryption. It delivers MPEG-4 H.264 SD and HD encoding, enabling broadcasters to transmit HD content efficiently over the same infrastructure used to transmit standard definition content. The Newscoder 4 input accepts either composite (NTSC or PAL), SD-SDI or HD-SDI inputs. The encoder automatically detects the video input format, digitises and passes it to a high performance H.264/AVC MP@L4 video encoder, where the video is compressed down to an extremely low data rate. The resulting output is an ASI transport stream. In addition, the encoder has
one stereo or two mono audio inputs and supports both line level inputs and microphone level inputs. Each mode supports independent gain selection ranging from 12 dB of attenuation to +50 dB and embedded audio. Featuring two RS232 ports,
one for remote control and a second for user data, the Newscoder 4 also employs AES encryption preventing unauthorised viewing of the signal. A video test pattern generator is designed into the NCTX-4 that can be controlled externally through the preset switch or programmed to be automatically enabled when the video input is lost. The encoder has an ASI input and output providing the ability to stack or multiplex multiple units. C6432
