Software Modules


Rile Reader, Writer, Codecs

Robust File Reader and Playlist

The File Reader module provides ready-to-use playlist capability to implement applications like video playout servers. The playlist function supports multiple video and audio elements, all of which can have different file and codec formats. Each video and audio element can be a whole file or part of a file (with the duration defined with trim in and trim out operations). Developers can also take advantage of the smooth scrubbing and seeking capability for searching content within the playlist. The Matrox File Reader module can support non-standard files. To guarantee 24/7 reliability, the Matrox File Reader module undergoes automated regression tests for each software release based on 50,000+ hours of media assets collected from worldwide broadcasters.

Compositor

Standards-Compliant File Writer

The File Writer module provides an easy and integrated way of capturing video, audio and ancillary data (closed captions, AFD, timecode, etc.) to many different industry standard file formats. It ensures the media assets are safeguarded in industry standard compliant formats. The File Writer allows appending and insertion of video and audio to existing files for significant time savings in live studio recording by avoiding post production steps. The File Writer in combination with the File Reader, Time Delay (TD) and Instant Replay (IR) functions enable to play back or edit video while recording. Advanced functions like faster than real-time transcoding and consolidation without decoding and re-encoding the essence make media management a lot easier and faster.

Compositor

High-Performance Software Compositor

The Compositor module provides the capability to mix multiple streams (or layers) of video, animation files, or graphics into one output video stream. Each layer can have its own alpha plane and transparency. The compositor supports upstream compositing with video and alpha outputs, and downstream compositing as final video output. The built-in intelligence automatically processes shaped or unshaped YUV, YUVA and RGBA video formats. This dynamic compositor supports infinite-layer compositing allowing creativity to be unleashed.



Software Scaler

High-Quality Software Scaler

The Scaler module can perform up/down/cross conversion between broadcast or custom resolutions. It can also be used to provide smooth and graceful sub-pixel positioning and scaling for video effects. In addition, it can be used as a down-scaler to provide proxy video for preview or streaming purposes. The software scaler can be applied to video or video and alpha in one pass. It is accurate to 1/256 pixel in 8-bit and 1/1024 pixel in 10-bit.







Video Effects

Versatile Video Effects

A set of software video effects like 2D DVE are provided for applications that need video processing. High quality chroma/luma keyers, with and without shadow, are ideal for virtual studio applications. Three-way selective color correction is done with highly optimized and sophisticated algorithms. Dynamic motion control for speed changes can be done with field or frame repeat or blending. A wide variety of fade, wipe and dissolve video effects are also provided.

Advanced Ancillary Data Handling

Advanced Ancillary Data Handling

Ancillary data is as important as video in broadcast applications. Matrox DSX SDK allows seamless processing, extraction, insertion and manipulation of ancillary data. It handles both HANC and VANC packets to cover common metadata such as closed captioning (CC), AFD, timecode and more. Matrox DSX SDK also enables conversion of VANC packets from one video standard to another, or from one specification to another; such as CEA608 to SMPTE 334 for closed captions.

Time Stamping

Precise Time Stamping

Matrox DSX SDK provides developers with sophisticated built-in system clocks to time stamp critical operations. The operations could include real-time or non real-time video processing and playout, with guaranteed audio, video and ancillary data synchronization. Within each of the system clock frequencies, video and audio data with different frame rates and resolutions can be processed and synchronized. Therefore, you can support SD, HD, 3G and 4K, all in the same process.

GPU Transfer

Low-Latency GPU Transfer

This module provides fast transfers to and from GPU memory. These efficient data transfers support both DirectX and OpenGL based rendering. This process applies to both I/O cards and host file playback to GPU memory. The GPU Transfer module also provides a deterministic delay that is mandatory for live graphics.

IP Streaming

Built-In IP Streaming

Through RTP, this module supports the receiving of IP streaming of MPEG-2 TS (transport stream) and provides demuxing and decoding of H.264 and AAC audio for further processing. On the output side, it encodes video and audio into an MPEG-2 transport stream with H.264 and AAC, and outputs via RTP network.

Fail-safe & Disaster Recovery

Advanced Fail-Safe & Disaster Recovery

For both hardware and software products, Matrox DSX SDK provides the most secure and fail-safe mechanism for on-air applications. OEMs can take advantage of this module to best handle a disaster recovery situation. The heart of this module is the Matrox Control Engine (MCE) which provides a sophisticated system recovery scheme with seamless transition between standard application control and failure recovery. For live production workflows, recovery can be completely glitch-free without any pipeline losses.

Easy Graphical Prototyping Tool

Easy Graphical Prototyping Tool

The Matrox Topology Builder application is a Java based Windows and Linux graphical prototyping tool that is provided with Matrox DSX SDK. It visually depicts all the components in the Topology API allowing users to build their workflows in the same logical fashion as developers would programmatically code their application. Topology Builder can be used by both developers as well as those without any programming knowledge. Users can simulate and validate complex workflows even before writing a single line of code. A user can simply drag and drop the components to create a workflow (topology) and test it.

DSX Core

Cloud-Based Media Processing

Matrox DSX Core is a complete set of 100% software-only modules for media processing in virtualized broadcast infrastructures based on Matrox DSX SDK. Modules include versatile file reading and writing, a large selection of software codecs and video effects, IP streaming and a precise system clock. OEMs can easily build IP- and file-based video applications such as ingest and playout servers, channels in a box, encoders and transcoders for broadcasters and service providers to use in media datacenters.

Instant Channel Deployment

DSX Core uses a floating license scheme that lets users move their applications from one virtual machine to another, or even to different datacenters. Developers can create software-defined virtualized IP channel solutions on COTS machines with DSX Core and let customers quickly and cost-effectively deploy specialty and event-based channels. Such software-only broadcast solutions can be easily repurposed as needed without any additional capital expenditure. DSX Core has built-in fail-safe capability to ensure deployed channels run trouble free. It also comes with a redundancy license model to facilitate disaster recovery.
