The OpenCable Application Platform is a game-changer for cable operators. It's a middleware solution that enables the development and deployment of interactive applications on cable networks.

This platform is built on top of the OpenCable specification, which provides a common framework for cable operators to deliver advanced services. The OpenCable specification is a set of standards that define how devices and applications interact with each other on a cable network.

The OpenCable Application Platform is designed to be scalable and flexible, allowing cable operators to easily add or remove applications as needed. This means that cable operators can quickly respond to changing market conditions and customer needs.

By using the OpenCable Application Platform, cable operators can reduce the complexity and cost of deploying new applications, while also improving the overall user experience.

What is OCAP?

OCAP, or OpenCable Application Platform, is a set of features that serve as the foundation for building applications on top of the CableCARD and Monitor application. It's essentially a core set of features that you can rely on when developing your OCAP application.

The OCAP Baseline consists of several key components, including the Executive, WatchTV module, EAS module, Captioning module, and Content Advisory module. These modules work together to provide a range of essential functions.

The Executive module is responsible for launching the monitor application and managing the life cycle of unbound applications, all while listening to XAIT signals and communicating them to the monitor app and other unbound applications.

The WatchTV module displays unencrypted content when a CableCARD isn't present, and it's required to set up a secure data channel and manipulate resources on the CableCARD once the CableCARD is inserted.

The EAS module ensures that emergency alerts are always visible, which is a crucial feature for compliance with FCC mandates.

The Captioning module renders both EIA 608 and EIA 708-b captions on the screen, allowing users to easily view closed captions.

The Content Advisory module enforces V-chip functionality, which lets families block content with unwanted sex, violence, and language.

These baseline features are not only essential for compliance with FCC mandates but also provide a solid foundation for building robust and user-friendly applications.

History and Transition

The OpenCable Application Platform has a rich history that spans over two decades. It was first introduced in 1999 as a way to standardize the development of interactive television applications.

In the early 2000s, the OpenCable project was led by CableLabs, a non-profit research and development consortium for the cable industry. CableLabs played a crucial role in shaping the platform's architecture and features.

The OpenCable Application Platform was designed to enable the delivery of interactive services, such as video on demand and interactive TV, over cable networks. This was a significant innovation at the time, as it allowed cable operators to offer more engaging and interactive content to their subscribers.

One of the key features of the OpenCable Application Platform is its ability to support multiple programming languages and development tools. This made it easier for developers to create applications for the platform, and helped to foster a vibrant ecosystem of third-party developers.

The transition to the OpenCable Application Platform was a gradual one, with many cable operators adopting the technology over the course of several years. By the mid-2000s, the platform had become widely adopted, and it continued to evolve and improve over the next decade.

OCAP is based on the Globally Executable MHP (GEM)-standard and was defined by CableLabs. This means it shares similarities with the Multimedia Home Platform (MHP)-standard defined by the DVB project.

OCAP exists in two versions: OCAP v1.0 and OCAP v2.0. These versions have distinct differences, although the article doesn't specify what they are.

The SCTE App Platform Std 1.0 includes support for multiple device types, including smartphones, tablets, and set-top boxes.

It also includes a data model for managing app metadata, such as app names, descriptions, and icons.

The standard provides a way to discover and launch apps on a TV device, using a standardized API.

This API allows developers to create apps that can be easily installed and launched on a variety of TV devices.

The SCTE App Platform Std 1.0 includes a set of APIs for managing app lifecycle events, such as app startup and shutdown.

It also includes a data model for managing user authentication and authorization.

Developers can use these APIs to create apps that securely authenticate and authorize users.

The standard provides a way to manage app updates and installations, using a standardized API.

This API allows developers to create apps that can be easily updated and installed on a variety of TV devices.

The SCTE App Platform Std 1.0 includes a set of APIs for managing app content, such as video and audio streams.

It also includes a data model for managing app metadata, such as app names, descriptions, and icons.

Developers can use these APIs to create apps that can manage and display complex content.

Comparison and Similarities

The OpenCable Application Platform (OCAP) has a lot in common with the Multimedia Home Platform (MHP). In fact, OCAP is actually a variant of MHP, designed for use in American cable networks.

One key similarity between OCAP and MHP is that they both rely on a common set of APIs, which makes it easier to develop applications that work on both platforms. This is made possible by the Globally Executable MHP (GEM) standard, which defines a common subset of OCAP and MHP that can be used across different variants.

OCAP and MHP share a number of features, including support for interactive services, multimedia home networking, and high-definition TV formats. They also both support the use of digital storage devices, such as hard drives, for recording TV shows.

Here are some of the different variants that are based on GEM:

  • MHP, as a software platform in DVB networks
  • OCAP, as the platform for American cable networks
  • ACAP, a platform for American terrestrial TV networks
  • ARIB B.23, a variant for Japanese TV networks (ARIB)
  • BD-J, a variant for Blu-ray Disc, which doesn't require broadcast support

These variants all share a common foundation in GEM, which makes it easier to develop applications that work on multiple platforms.
