چکیده

The number of bandwidth-hungry applications and services is constantly growing. HTTP adaptive streaming of audio-visual content accounts for the majority of today’s internet traffic. Although the internet bandwidth increases also constantly, audio-visual compression technology is inevitable and we are currently facing the challenge to be confronted with multiple video codecs. This paper proposes a multi-codec DASH dataset comprising AVC, HEVC, VP9, and AV1 in order to enable interoperability testing and streaming experiments for the efficient usage of these codecs under various conditions. We adopt state of the art encoding and packaging options and also provide basic quality metrics along with the DASH segments. Additionally, we briefly introduce a multi-codec DASH scheme and possible usage scenarios. Finally, we provide a preliminary evaluation of the encoding efficiency in the context of HTTP adaptive streaming services and applications.

Generating automatic pseudo-entailments from AMR parses

We explore how to generate a textual inference dataset from Abstract Meaning Representations (AMR) (Banarescu et al., 2013). Various aspects of AMR make it problematic to automatically derive inference patterns. Therefore, our generated dataset instead answers questions regarding the relation between entities and actions in sentences. We refer to these answers as pseudo-entailments. From this d...

GSM EFR based multi-rate codec family

This paper describes a multi-rate codec family developed as a potential candidate for the GSM Adaptive Multi Rate (AMR) codec standard. The codec family consists of the GSM Enhanced Full Rate (EFR) codec [I] and lower bit-rate extensions thereof: The codec family consists of several codecs, i.e., modes that have different bit-rate partitionings between source coding and error protection. All th...

UofR at SemEval-2016 Task 8: Learning Synchronous Hyperedge Replacement Grammar for AMR Parsing

In this paper, we apply a synchronous-graphgrammar-based approach to SemEval-2016 Task 8, Meaning Representation Parsing. In particular, we learn Synchronous Hyperedge Replacement Grammar (SHRG) rules from aligned pairs of sentences and AMR graphs. Then we use Earley algorithm with cubepruning for AMR parsing given new sentences and the learned SHRG. Experiments on the evaluation dataset demons...
