The MPEG professional Encoders, designed and produced by ABE, represent a latest technology quality solution for a very attractive price!
ABE Encoders compress video signal (digital, analog composite or YC, both PAL and NTSC) in real time, together with audio channels, producing an MPEG transport stream with a bit-rate which can be adjusted from less than 1Mbit/s up to over 20Mbit/s.
This product is extremely flexible and the number of parameters which are user adjustable (through the relative software) is very high: over 200. For example, the video and audio encoding bit rate can be adjusted, the video resolution, the GOP length and structure, the filters, the PID, the audio sampling frequency, video analog to digital converter parameters (comb or notch filter, level control, etc.) and several others, can all be adjusted. In the internal memory, the encoder stores many configurations which can be easily recalled.
Besides this, ABE Encoders extract Teletext or Closed Captioning data from video analog or digital signals making them available for the multiplexer, which inserts them into the transport stream.
The ABE multiplexer combines the outputs of different encoders, producing a multi-program transport stream. The multiplexer can also “re-multiplex,” modifying existing transport streams, adding or deleting programs and/or data (for example MHP data - the Multimedia Home Platform); it also includes and/or modifies tables (for example NIT - Network Information Table - SDT containing program names, TDT, EIT etc.). The configuration software is supplied with the product.
ABE encoders and multiplexers are offered in a wide variety of choices for each solution; for example, a single 19” 1U standard rack chassis can house up to 4 MPEG encoders, the multiplexer and also a digital modulator (according to the DVB-S, DVB-S2, DVB-DSNG, or the DVB-T/H standard), so to be suitable for different uses: from microwave links to digital terrestrial transmitters to satellite uplinks.
