Simple exercises will be discussed involving real-world applications giving participants a hands on experience on the underlying operations associated with video communication. This lab session will introduce video streaming technologies using ffmpeg encoding tools, ffserver and MPEG-DASH. In addition, 5G features that potentially support 4K video streaming over wireless networks (frequency bands, duplexing techniques, millimetre waves, small cells, massive MIMO, beamforming etc.) will be discussed.Ģpm - 5pm - Video streaming basics: (Lab session) This lecture covers an overview of 5G communication infrastructure, practical issues in achieving ultra-low latency and reliable connectivity to realize high definition real-time mobile video transmission. This lecture introduces the concepts of video communication covering packet based video transmission, error resilience, error concealment, robustness of video encoders and content adaptation in video transmission.ġ1am - 12:30pm - Challenges in video content delivery over 5G networks In addition, stream analyser tools (Gitl HEVC Analyzer), will be used to discuss the bit stream syntax elements of both H.264/AVC and HEVC standards. Media distribution phases including encoding, packetization, multiplexing and streaming examples will be discussed using real-world applications. In this context, research oriented HEVC encoding and decoding tools (HM Test Models), openHEVC decoding tools, and commercially used ffmpeg tools will be introduced and their operational aspects will be demonstrated using experimental tasks. Moreover, high level syntax elements, reference picture architecture will be introduced followed up by the challenges faced in HEVC based video coding.Ģpm - 5pm - Introduction to video coding tools: (Lab session)įollowing the introduction to video coding in HEVC, this lab session will cover the state-of-the-art video coding and analysis tools together with the evaluation metrics. This lecture will cover the HEVC encoding architecture, comparison of H.264/AVC and HEVC coding tools, intra- and inter-prediction tools, transform coding, quantization, entropy coding and in-loop filtering algorithms with respect to HEVC will be discussed. In addition, implications of video coding in video communication, video quality, error resilient and concealment aspects of video transmission will be discussed. This lecture will cover basic concepts of image and video compression, evolution of video coding standards and applications, and overview of relevant text books and reference materials in the field. 9am - 10:30am - Introduction to image and video compressionĪn introduction to the whole course and its structure.
