Direct MPEG subtitle, logo and delay insertion
The Polistream M-Series is our innovative solution for real-time subtitling, logo insertion and video delay, all in MPEG. The M-Series and be configured to insert subtitles and static logos directly into HD or SD MPEG streams.
The M-Series Delay Module can be used to create delayed (+1) channels, to time shift peak programming to different time zones and for NVOD channel creation. By working directly on the Transport Stream the M-Series provides very cost effective solutions when compared to conventional video delay systems.
By using the very latest MPEG2 processing techniques to modify the MPEG video streams in real time without decoding and recoding the whole picture so reducing cost and preserving video quality.
Adding the data to the MPEG stream in real time provides considerable savings in cost and rack space and is therefore by far the best solution for those needing to transmit MPEG subtitles and other localized data.
