OPR-T16 ST-Mux Transcoder with ASI Output - Spatio-Temporal Domain Statistical Multiplexing Transcoder

Transform Your Broadcasting with Unparalleled HD Transmission Efficiency - ST-Mux Transcoder T16 Transcoder

1. Only 21 Mbps for 16 HD Channels – Achieve stunning quality with unparalleled bandwidth efficiency, significantly reducing costs!
2. Advanced Statistical Multiplexing Encoding – Boost channel capacity by 2-3 times without sacrificing video quality, optimizing bandwidth usage and reducing transmission costs.
3. Simplified Infrastructure – Fewer multiplexers mean less wiring, a smaller equipment footprint, and lower failure risk, streamlining your entire front-end system.
4. Substantial Cost Savings – Eliminate redundant systems and cut annual electricity bills by reducing power-hungry devices.

The OPR-T16 ST-Mux Transcoder with ASI Output is a cutting-edge device that uses spatio-temporal domain statistical multiplexing encoding technology to deliver more TV programs with less bandwidth. By leveraging the non-correlation between programs, each program in the channel shares the bandwidth of a channel, and the bitstream is dynamically allocated among programs, as shown in the figure, which enhances coding efficiency by 2-3 times. This device can handle network UDP unicast and Multicast SPTS input and output network UDP multicast/MPTS and ASI, with a maximum processing capacity of 16 program channels. It also supports remote connection for operation and maintenance.

What is Spatio-Temporal Domain Statistical Multiplexing?

The core of this technology is the Spatio-Temporal Statistical Multiplexing Encoding technique, which exploits the non-correlation of multiple programs. It analyzes the current and future bitrate requirements of all programs frame by frame, and dynamically determines the encoding quality of each frame. All programs share the total physical bitstream, which is dynamically allocated among them. This technique enables us to use limited spectrum resources more efficiently, meeting the growing demand for high-definition video transmission.

In terms of strategy, spatio-temporal domain statistical multiplexing has two aspects: time and space. In terms of time, it uses a 'Look Ahead' approach, which pre-encodes the video in advance to obtain the necessary information. In terms of space, it uses a 'Look Around' approach, which monitors the pre-encoding situation of each video path in real time, and adjusts and controls the encoding of each video path.
