RomPlug Application Development Toolkits for Connected CE

upnp dlna toolkitAllegro’s RomPlug suite of development toolkits offers your engineering team flexible and robust technology to build state of the art UPnP and DLNA enabled consumer electronics and mobile devices. In addition to Allegro’s core RomPlug UPnP / DLNA technology, Allegro offers a variety of application-specific toolkits to create DLNA Digital Media Players (DMP), Digital Media Servers (DMS), Digital Media Renderers (DMR) and Digital Media Controllers (DMC). Additionally, Allegro supports the DLNA specified link protection protocols with the RomPlug DTCP-IP and the latest interoperability guidelines (VidiPath™) with RomPlug VP. Allegro’s RomPlug IGD toolkit provides the UPnP frame for creating an Internet Gateway Device. Your engineers will save time and money with Allegro’s proven and stable implementations of industry standard protocols that comprise the UPnP and DLNA architecture.

UPnP / DLNA Standard Toolkits

RomPlug MediaPlay Toolkit

Digital Media Players (DMP) closely model how audio video devices perform today with the simplicity of the DLNA 2 box model. DMPs discover and browse content on Media Servers much like using a program guide and then play selected content. Allegro’s RomPlug MediaPlay Toolkit combines the benefits and features found in the RomPlug MediaControl for discovery and browsing content and MediaRender toolkits for controlling playback of content from media servers.

  • API to retrieve and parse device and service descriptions
  • API for event subscriptions
  • Flexible framework to create a DMP that complies with DLNA DMP guidelines

RomPlug MediaServe Toolkit

Media Servers perform a significant role in all home networks. The CE competitive landscape requires device vendors to be innovative with their feature sets for media servers. Allegro’s RomPlug MediaSeve toolkit enables developers with a rich API and flexibility to support and foster product differentiation within a DLNA network.

  • Serves device and service descriptions without application interactions
  • Event subscriptions are initiated and renewed without application interaction
  • State variable changes are automatically communicated to control points transparent to the application
  • Toolkit provides a rich API for device specific actions

RomPlug MediaRender Toolkit

In the competitive arena of home networking and DLNA devices, companies creating Media Renderers differentiate their products with advanced intellectual property to produce compelling products. Allegro’s MediaRender Toolkit provides the framework and flexibility to create innovative Media Renders that endorse DLNA networking throughout a home.

  • Serves device and service descriptions without application interactions
  • Many Control Point actions handled by the toolkit without application interaction
  • Toolkit provides a rich API for device specific actions
  • DMR easily complies with DLNA DMR guidelines
  • DMR supports Microsoft “Play To” capabilities

RomPlug MediaControl Toolkit

In a DLNA home network with potential for gigabytes of digital audio, video, and photos a Digital Media Controller (DMC) is critical to managing available content on the network. Building a reliable and robust DMC that can discover media servers and browse content in addition to discovering media renderers and their capabilities presents a significant challenge. Allegro’s RomPlug MediaControl toolkit enables device manufacturers to focus their efforts on product differentiation rather than concentrating on the intricate details of media control UPnP/DLNA communications.

  • API to retrieve and parse device and service descriptions
  • API for event subscriptions
  • Event messages are automatically parsed and passed to the application
  • Extremely flexible with API for device specific actions

RomPlug VP Toolkit

The RomPlug VP Toolkit extends Allegro’s DLNA support for VidiPath, the latest DLNA interoperability standard. The RomPlug suite of software toolkits provides OEM developers with a rich framework to support the underlying requirements of VidiPath, such as: DTCP-IP for Protected Streaming, HTML5/RUI for Distributed User Experience, UPnP Energy Management for sleep mode support, DASH for adaptive delivery, client authentication technology, and transport and link layer diagnostics technology.

  • Fully integrated with UPnP/DLNA protocols
  • Integrated framework
  • HTML5/RUI support
  • Diagnostic (DIAG) support
  • Authentication (AUTH) support

RomPlug IGD Toolkit

Internet Gateways are essential network components for accessing wide area networks. Allegro’s Internet Gateway Device (IGD) toolkit provides a networking framework to create UPnP based IGD products that are easy to use.

  • API for service action events (Layer 3 forwarding, WAN Configuration, etc.)
  • Evented variables automatically communicated to subscribers
  • Flexible framework for creating IGD products

UPnP / DLNA Security Toolkit

RomPlug DTCP-IP Toolkit

DLNA has chosen DTCP-IP for link protection for home networking environments. Allegro’s RomPlug DTCP-IP toolkit enables your design team to easily integrate DTCP-IP security technology for streaming protected digital media content to DLNA enabled consumer electronics and mobile devices.

  • Fully compliant implementations of DTLA DTCP-IP
  • Routinely qualified at ongoing industry interoperability plugfests
  • Fully integrated with the RomPlug suite of products
