Subject: Development and optimization of a state-of-the-art video encoder

The COVID-19 crisis once more showed how dependent are our societies on digital video broadcast. An industry which is itself highly restricted by the bandwidth for distribution of a tremendous amount of video over different transportation means (Terrestrial, Satellite, Internet, mobile). This increase in video consumption leads to a massive usage of computational resources in datacenters. This has two principal impacts. First, the encoding costs for service providers and broadcasters grow since they re often charged on a CPU/Bandwidth-usage basis. Second, the increase in energy consumption and its impact on the environment are more important.

The latest state of the art video codecs are AV1 (2018) and VVC (2020). AV1 is the first video codec developed by the Alliance for Open Media (AOM), including major actors from the information technology field, such as Google, Amazon, Meta, Netflix, Nvidia. It has been proposed as a royalty free alternative to the traditional video coding standards.

H.266 / Versatile Video Coding (VVC), on the other hand, is the latest of a long and successful line of video coding standards produced by the joint effort of ISO MPEG and ITU VCEG, gathering hundreds of video coding expert from all around the world.

The promising performance of the state-of-the-art video codecs compared to its predecessors, in terms of bitrate saving, pushes the broadcast industry towards a quick adoption. However, the performance improvement comes at the cost of more complexity and requires more computational power. In order to limit the datacenters energy consumption while deploying new codecs such as AV1 and VVC, careful algorithmic and software optimizations must be conducted.

Ateme is committed in the adoption of the latest video coding technologies. Therefore, Ateme has been developing an industrial implementation of AV1 and VVC encoders in its products. As with every codec generation, the first encoder version does not include all the features of the standard. Also new coding tools requires specific algorithmic design and optimization.

This internship will consist of following phases:

1. Study of the principles of video coding.

2. Getting to know the Ateme implementation.

3. Study, implementation, and test of selected coding tools and/or versatility features

4. Integration in the Ateme software, performance measurement and optimization.

In all above phases, candidate will constantly interact with his/her colleagues to benefit from their knowledge and experience. Noteworthy of precising that, based on the profile of candidate, the internship orientation might be adjusted.

About the candidate:

• Last-year student of engineering school program or master s in computer science or electrical engineering.
• Excellent C/C++ programming skills.

• Ability to read and understand academic papers in the domain of image and video processing.
• Being familiar with video compression algorithms is a plus.
• Fluent in English.

Location: The position is based in Rennes (35) or V lizy (78).

Duration: 6 months (minimum)


Benefits: 1500 gross + Ticket restaurant + Reimbursement of transportation fees + possibility of recruitment (CDI) or CIFRE thesis
