How to marry TV and IOT through leanback experience ?
I joint in a project called ConnectedLife where "internet of everything" was key to the home automation ecosystem :
- managed by openHAB as a "conduction": open-source solution addressable by REST API
- localisation fulfilled by:
* BLUETOOTH detection => iBeacons
* WIFI triangulation => Cisco equipment (MSE, Prime)
* RFID identification => impinj equipment (Speedway)
- delinearized TV channel:
* like Youtube channel (meaning playlist of movies set according to profile preferences)
* profile-based playgraph pre-determined according to analytics features offered by Cisco
* business logic offered to operator around playgraph nodes by inserting advertising
- real-time ambilight effect all over home saloon in :
* by gstreamer implementation applied onto frames of current TV stream to compute colorimetry
* ambilight split into HUE Philips lights spread all over home saloon managed by Zigbee bridge
Main UI/UX rendering video content (current delinearized TV channel is made of) has been designed in Dart/WebGL.
Communication between werables (watch) and companion devices (Samsung mobiles) happened by webSockets across dedicated notification servers based on node technology.
Demo presented at CES 2015 and selected for Mobile World Congress event in Barcelona.

HTML5 implementation of a WebApp for ZON TV Portugal
Our small team of three people has created a proof of concept of WebApp destined for ZON TV Portugal. Application for TV has been implemented in :
- raw JS
- CSS3 rules
- HTML5 instructions
Our source code has raised without any framework by "settling" our own tiny UI_Manager to arrange MVC views. We used our own data model aggregation by developing one proprietorship embedded solution based on QT, part of RDK middleware => to ease/speed requests addressed from end-user STB to remote ZON Tv Portugal back-ends.
I took part in developing several MVC views like :
* channel list
* channel banner
* EPG grid
I have been involved at every stages of the project:
* from-sratch development,
* continuous integration by Jenkins
* scrum sessions,
bugfixing, managing deliveries, JIRA backlogs

- BackboneJS + ThreeJS Front-End developer

2014 - 2014
HTML5 implementation of a WebApp selected by Belgacom
I have been part of developments to package HTML5 application for TV (called EPG) running on RDK as a " middleware ", delivered to Belgacom. Including :
- CSS3 (CSS3D 'instructions' to leverage on HW acceleration by GPU)
- vanilla WebSockets, and AJAX requests across framework, meaning Backbone
- modern javascript methods (HTML5 APIs)
our WebApp mixed both :
- regular HTML content (with CSS +JS)
- WebGL content managed by Three.JS as top level library according to COLLADA rules to describe objects model furnished by graphic designers
- Objects model were displaced by Tween.JS
- Objects model had background color changed by Tween.JS
Data aggregation happened remotely, server side.
our WebApp has been a bit tailored at the end to run on tablets:
- Ipad (meaning iOS8)
- Android (Nexus 10)
owing to Hammer.JS inserted in our Backbone-centric framework for swipe events.
I packaged this WebApp for our customer by using remote cross-platform tools (Adobe PhoneGap , CocoonJS) but the result was never presented yet, due to other priorities/choices.
Much time has been consumed to fine-tune our WebApp smoothness, cleverly balancing around HW acceleration : "as much as possible but not too much", for the sake of performances, due to our platform and the way webkit had been embedded inside RDK. Application has been a bit modified with effort to preserve execution on low profile "poor" STB that don't support WebGL. Under competition => we won the trend.
------------------------------------------------------------------------------
In the meantime, I spent (spare ;-) time to figure out an external resource super-specialized in WebGL: I "sacrificed" PTO on my budget, to get to his teaching sessions at engineering school. To make up my own mind, 1st. Then to convince managers here to let this expert organize a 5 days long training in our company, for low-cost wages, and successful result => other sessions already planned.

- WebRTC : real phone-calls prototyped for TV
Issy les Moulineaux
2013 - 2013
Guest Speaker to yearly DevConf evangelizing WebRTC
Again, my topic has been selected for 2013 yearly event called DevConf.
I presented a tutorial about WebRTC.
From general prospective, first. I managed to fulfill a use-case where the audience (simulating payTV subscribers) managed to receive a real phone call from main EPG application designed in HTML5 that was running on my laptop (simulating a STB).
Then, more especially, I explained how I would proceed how to give our RDK stack WebRTC-ready to let subscribers organize webEx @home across their set-to-box. Ratings granted for my presentation have been high: more than 80% of satisfaction.
That makes four times/years in a row that my topics have been selected by DevConf commitee and that I had the opportunity to attend such meetups that happen worldwide.

Issy les Moulineaux
2013 - 2014
wabapp developed in HTML5, CSS3D, for embedded devices (smart TV, Rpi) released for CES 2014 :
* running on every-device: LgTV, HDMI stick, tablets, laptop
* implemented in HTML, JS, CSS3D, WebGL, based on :
- backboneJS for MVC logical unit
- ThreeJS 'engine' (top of WebGL to speed up prototyping /b COLLADA)
- TweenJS interpolation 'engine'
- adapting FPSMeter in embedded conditions
- HTML5 content accustomed (few changes) to please every device. Mac especially. Working especially to have fit-to-with rendering, "centered" for each device, with onResize needs.
* participation to green-house-on-fire with Canadian graphic designers
* isolation of one < view > as a Web Component by Polymer
* JsDoc generation by commenting source code to match YUIDoc templating
* HTML5 engines assessment to qualify HW acceleration (leveraging on GPU) on each :
- QT5 / Webkit1
- WebKitNix (thin layer port, top of POSIX, and openGL/EGL)
- Chromium
* selected HTML5 engines cross-compiled to be ported onto embedded devices :
- LG TV: tiny involvement only in x-compilation, but high involvement in adjusting HTML5 content
- Raspberry PI: medium involvement here => I managed to build / setup DDD to debug WebKitNix
- Cotton Candy (FXI): small involvement in x-compilation, but high one in adjusting HTML5 content
- MacOSX: high involvement in x-compiling WebKitNix by Xcode. And by cmd line. Light changes applied in MiniBrowser boostrap in Objective C (e.g. to get content full screen)
Build of Gstreamer for Win32 and MacOSX:
Required to compile gstreamer (meaning core, plugins, ... ffmpeg) manually by cmd line
- for WIN32 (either by Cygwin or MinGw, successfully, or by Visual C++ less successfully)
- for MacOSX => successfully
Several extra deps / libs had to be compiled 1st, and installed, as a pre-requisite.
Complete goal was to leverage on HW acc twice: both by WebKit (graphics) and by Gstreamer (video) on every device (tablet, smartTV, laptop)

Acoustic Echo Cancellation (AEC) for handsets.
Final client : VOX.
refers to a general class of signal processing algorithms designed to identify and eliminate the sound of a loudspeaker within a background of various other sources. The main application of an AEC in the context of this project is the echo cancellation in communication where it is desired to prevent the retransmission of any sound coming from the loudspeaker back to the far-end talker during a call.
I used convolution algorithm over MATLAB on record samples to detect echo delay and attenuation. Then I developed a program written in C to trigger simultaneous echo cancellations by several threads to apply it on multiple speech channels (each audio card furnished by by VOX could manage different channels of communication)
