|Low-latency H.264 / MPEG-2 video encoder for SD and HD, without audio-encoding licenses.|
|The base version of the DTA-2182 does not include licenses for audio encoding. Please refer to encoder options for an overview and pricing of audio-encoding options. |
Please find below a number of examples of the DTA-2182 bundled with audio encoding:
|Dual H.264 HD encoder for PCIe with with AC3, AAC and/or MP1LII audio encoding for any number of channels.|
|Dual H.264 HD encoder for PCIe with 2 license points (1x stereo) for AAC audio encoding.|
|Dual H.264 HD encoder for PCIe with 4 license points (2x stereo) for Dolby Digital (AC3) audio encoding.|
|Dual H.264 HD encoder for PCIe with 2 license points (1x stereo) for MPEG-1 Layer II audio encoding.|
Prices exclude applicable sales tax, shipping charges and customs duties. Quantity discounts may be available, please request a quotation.
The encoder input is taken from one of the two HD-SDI ports and 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-2182 can also extract Dolby metadata in RDD6 format from the SDI input signal.
The audio, video and closed captions 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, for example to IP.
Creating an Application for the DTA-2182
The DTA-2182 can be used out of the box with the DtEnc utility, see below (Windows only). Creating a custom application for the DTA-2182, either on Windows or on Linux, is easy with the DekTec SDK (DTAPI). A dedicated reference document is available, containing a description of the audio/video encoding classes and a tutorial with examples on how to use them. It is included in the Windows and Linux DekTec SDK distribution file, available on the downloads/SDK page.
DtEnc - Controlling the Encoder
DtEnc is a free Windows application for controlling the encoding parameters of the DTA-2182, and for monitoring the input- and encoder status. Multiple instances of DtEnc can be started to control each of the two encoders on the card. The main parameters that can be set are the audio- and video-encoding parameters. The screenshots below provide an impression of the parameters that can be set and monitored with DtEnc.
