TAL -- TV Application Layer
TAL Replacement update 28/09/2023
We are working towards an approach of modular packages focused on specific features such as playback, navigation, and device abstraction. We do not intend to provide a UI framework, and these packages should work with a number of front-end frameworks. As part of this work, we are in the process of making internal TV packages open source. Some of these have been released already including:
Looking further to the future, we are developing an open source demo app, including associated documentation. This will enable the wider community to understand how these packages work together to build a TV application.

We have now created a mailbox where you can contact us with any questions related to TAL or the future of this project. We aim to respond to emails within a week. We hope to share some details of the replacement to TAL soon.
Deprecation Announcement 12/12/2022
Today we are announcing the deprecation of TAL. This will allow us to concentrate on future work, which we hope to share details of soon.
We apologise that we were not active in keeping the TAL community up to date with the status of the project. Going forward, we will provide regular updates on the future of TAL.
As part of the deprecation, pull requests will be disabled and outstanding issues will be closed. TAL will not be actively maintained.
We will answer any questions found in the issues backlog as best we can. There will soon be a email address you can use to contact us. This readme will be updated when this becomes available.
TAL was developed internally within the BBC as a way of vastly simplifying TV application development whilst increasing the reach of BBC TV applications such as iPlayer. Today all of the BBC's HTML-based TV applications are built using TAL.
There are hundreds of different devices in the marketplace and they all use slightly different technologies to achieve the same result. The purpose of TAL is to allow you to write an application once, and be confident that it can be deployed to all HTML-based TV devices.
