DTA-2180 – H.264/MPEG-2 HD/SD Encoder for PCIe

Features

• Real-time H.264 or MPEG-2 video encoder for HD and SD formats, and with multi-channel AAC, AC-3 and MP1LII audio encoder.
• Audio/video input taken from HD-SDI, or from HDMI for encoding the output of a graphics card.
• Includes a transport-stream multiplexer with low-latency ASI output. The TS is also available on PCIe for reading by a PC application.

Applications

• General-purpose H.264 program encoder for real-time encoding of an HD-SDI or HDMI signal.
• H.264 encoding of the contents of a PC desktop, running e.g. a slide show.
• High-quality encoding of the graphics output of a PC application.

Block Diagram

The encoder input is taken either from the HD-SDI port, or from the HDMI port. The A/V signal is split into a video part and maximally 8 audio pairs. An audio crosspoint switch connects these audio pairs to any of the 8 audio encoders. The DTA-2180 can also extract Dolby metadata in RDD6 format from the SDI input signal.

The audio, video and closed captions (only for SDI input) are encoded and multiplexed using a Magnum encoder. The resulting transport stream is connected in hardware to an ASI output port, providing low latency. The transport stream is also routed to the PCIe bus, so that applications can read and process or forward the encoded transport stream.

DtEnc – Controlling the Encoder

DtEnc is a free Windows application for controlling the encoding parameters of the DTA-2180, and for monitoring the input- and encoder status. The main parameters that can be set are the audio- and video-encoding parameters. The screenshots below will give you an impression of the parameters that can be set and monitored with DtEnc.
