The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware. It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
The BlinkenServ (or BlinkServ) is a project aimed at developing software for the Simple Blinkenlights Transport Protocol. It currently provides a graphical server suite that features streaming, file sharing for blm movies, and uploading of love letters and the ability to play them on demand. It includes a stream viewer (compatible with CCC's blccc) as well as a file sharing client that uses the SBTP protocol.
Coherence is a set of DLNA/UPnP devices, like MediaServer and MediaRenderer. In addition, it includes a well-designed framework to extend other applications with DLNA/UPnP functionality. It also has an emerging DBus API, enabling these applications to participate in digital living networks. It supports Playstation 3 (PS3), XBox, and many other devices.
The Helix DNA Server is a universal media delivery engine that supports the real time packetization and network transmission of any media type to any device. It includes support for MP3 audio (.mp3), RealAudio, and RealVideo (.rm, .ra, .rv). Other data types are supported through the Helix Universal Server. It uses RTSP/RTP streaming delivery for standards-compliant clients and proxies, an RTSP cloaked protocol over HTTP, and media data delivery via TCP, UDP unicast and multicast, and HTTP.
