Two years after the completion of the 1st edition of the AVC standard MPEG organised a Worshop on Future Directions in Video Compression (Busan, April 2005). The purpose of the workshop was to inquire about the prospects of a new generation of video compression standards. As no definite answer could…
Coping With An Unpredictable Internet
Dynamic Adaptive Streaming over HTTP (DASH) is a media-streaming standard in which the client has control of the server-client information flow. Clients may request data using the HTTP protocol from standard web servers even if the servers may not have DASH-specific capabilities. The DASH standard primarily defines two formats: The…
Inside MPEG-H – Systems
MPEG Media Transport (MMT) has been designed to support the second half of the MPEG-H title “Media Delivery in Heterogeneous Environments” and is based on the following assumptions IP-based delivery: packet oriented, with relatively large jitter, and use of internet protocols and functionalities (e.g. NTP) Two-planes: data plane for media…
MPEG-H Inside – 2D Video
The video coding layer of HEVC is based on the typical “hybrid” approach (inter- and intra-picture prediction and 2D transform coding) with some key differences that enhance compression. Figure 1 gives a high-level reference diagram Figure 1 – HEVC encoder block diagram Here is a list of the main technical…
