LEADTOOLS DirectShow Filters C API Introduction

Summary

The DirectShow® filters C API provide multimedia components that can be used to compress, decompress, process, enhance, or stream video and audio data. Codecs (Compressers-Decompressers) encode (create) and decode (play) audio and video files. LEAD iCompress codecs support industry standards using LEAD's own industry-leading compression algorithms.

Use the LEAD iCompress codecs to compress large media files with no perceivable loss of quality. Additionally, compressing video down to 20% of its original file size makes the video easier to share, stream online, or place on popular handheld devices.

LEADTOOLS Medical SDK

The LEADTOOLS Medical SDK includes a suite of state-of-the-art DirectShow filters for compressing and decompressing video and audio data inside DICOM files. This feature-rich product was designed to simplify converting cine images and video streams to DICOM objects. DICOM objects include X-ray Angiography (XA), Ultrasound (US), Visible Light (VL), Secondary Capture (SC) objects, and many more. This Filter Pack uses the most advanced compression DICOM standard algorithms used in the industry, including MPEG-2, Motion JPEG, and JPEG2000.

The Medical Module SDK includes two components:

• The LEAD DICOM Writer includes the DirectShow filters used to create DICOM objects with compressed video and audio data.
• The LEAD DICOM Reader includes a set of DirectShow filters that register into the Windows collection of multimedia drivers and integrate with any application using DirectShow.

Existing video software, such as Windows Media Player and Ulead Media Studio, use these filters to play the video (cine) data in a DICOM file.
