Non-live subtitles personalization for VoD over HbbTV devices

by Rafael Bermúdez and Jordi Fabregat

This article describes the approach taken by a broadcaster to achieve the commitment of enable non-live subtitles for video on demand on HbbTV devices, and carry out an advanced implementation of subtitling EBU-TT standard (ref. EBU Tech 3350). The key concept is to map EBU-TT XML elements into HTML layer and CSS styles. The logic is controlled from Javascript language. Regrettably, we can’t reach 100% of available market due low performance experienced on 16% of devices. Inside, reader could find explanied several challenges and solutions for structure information and map to HTML and CSS the normative attributes, and reach the necessary accuracy to synchronizing subtitles with video. The approach taken is a time-based instead of frame-based. Last, once reached functional version, the article concludes describing subtitle personalization functionalities. The customizable parameters are change the background color, customize the font size or modify a top or bottom subtitle position.

MPEG DASH multiple video implementation over one single manifest

by Sergi Màrquez Andreu

1

The aim of this article is to explain how we created a MPD (Media Presentation Description) with multiple videos in a single asset. To realize this, we have used the tools provided by TVC in order to correctly produce and deliver of multiple videos MPEG DASH steams. This topic has been developed of TVC participation on TV-RING European project. The relation with HBB4All European project is close because we have done a similar task in that project by incorporating multiple audios in a single asset. More information about these projects and the tools that we use, are available at the links at the end of this article. Read more ›

Co-creation for HbbTV development – Part 2

Internal workshop at RBB: Early Paper Mockups

1

The first workshop was the starting point of the development process and involved editors and engineers. Here, a list of key features of the service was defined and several paper screens were developed with different alternative solutions for certain functions, using cardboard, paper, glue and pencils, incorporating all the major features of the planned application.

Co-creation for HbbTV development – Part 1

How to start developing ideas and to evolve them towards a prototype stage is always a hard task. Especially in the field of HbbTV applications with screen space and ways of interaction very limited. In this article we would like to discuss a specific part of the approach RBB took for developing the service for the German TV RING pilot. The co-creation part. Read more ›

This article will discuss how to create a video mosaic using FFMPEG and how to adapt an HbbTV 1.5 application to use the second-screen to select the content and then view the program into a smart-TV. The purpose of this application is to provide multi-camera content and make the change camera interface is more intuitive and friendly face to end users. This topic has been developed of TVC participation on TV-RING European project. There are links at the end of this article for more information about this project. Read more ›

Developing Applications for Social Connected TV

The EU project FIcontent2 created a document with “Guidelines for Developers and Content Producers”.  The study is divided into three sections:

  • Social Media Guidelines
  • Usability Guidelines
  • Data & Privacy

The Social Media Guidelines are based upon broadcaster recommendations for media producers/editors producing content for own platforms, for third party platforms and for self-operated social media platforms.

The usability guidelines are aimed at developers, designers, content/media producers and distributors working within the TV/broadcast/content creation and distribution domains. The guidelines are intended to support the optimal development and operation of HbbTV, IPTV, Smart TV and Red Button technologies and related applications.

The data & privacy guidelines are aimed at developers working within the TV/broadcast/content distribution domains. They represent a synthesis of current thinking and draw particularly on conditions in the German market. They are based upon current practices and on user studies carried out by the EU-funded FIcontent project.

Designing for HbbTV

by Andrea de Vries

The first time I saw non-Dutch HbbTV was on a TV connected to a satellite. This TV had many channels that offered red button interaction, most of which looked as if they were designed a very long time ago. For me as a designer this is actually pretty great since whatever I design is bound to be a step up from that! Even though the style of these old HbbTV designs does not look as modern, there are good things to be found; like big, visual buttons. In my career as a TV designer I discovered more of these lessons about TV design, which I would like to share. Read more ›
