H2B2VS is at the initiative of the 1st MPEG workshop on Media Synchronization for Hybrid Delivery which was held in Strasbourg on October 22nd, 2014 (see invitation). This seminar was open to the public. Chaired by Marco Mattavelli from EPFL (H2B2VS partner), this workshop invited 6 speakers who presented an overview of the state of the art in this area (see presentations). H2B2VS was represented by Raoul Monnier who gave a talk on H2B2VS Use Cases and Business Models. A panel discussion was organized at the end of the workshop so that the speakers could answer the questions from the floor. Followed by more than 80 participants, this workshop was a success and attendants suggested the organizers to hold a 2nd edition within 2 years. In parallel to this workshop, demonstrations where organized. H2B2VS illustrated three Use Cases: Trick-mode on broadcast event, Multi view programme, Hybrid delivery of 4K scalable HEVC...read more
H2B2VS partners presented the first demonstration of hybrid content delivery by showing how to synchronize the 2 layers of a SHVC encoded video. With the parallel development of scalable extensions for HEVC (SHVC, MV-HEVC) and timeline and external media information carriage in MPEG-2 TS (TEMI), MPEG is creating the foundation of future services for the broadcast industry: flexibility and extensibility in media coding, carried over using heterogeneous networks, including broadcast and broadband networks. As part of the H2B2VS project, Telecom ParisTech and INSA/IETR have been working on a tight integration of scalable coding and transport layers through their respective open-source projects GPAC and OpenHEVC. This contribution demonstrates the combined usage of HEVC/SHVC, multicast MPEG-2 Transport Stream and on-demand MPEG-DASH in a prototype...read more
Following the project’s contribution to the 107th MPEG Meeting in San José, California, WG11 has sent a liaison letter to DVB informing of the on-going work on timeline signaling in MPEG-2 TS, 13818-1:2013 DAM6. Some fruitful discussions happened in DVB CSS group, including some members of the H2B2VS project, and a liaison letter was sent back to MPEG (m31817). H2B2VS contributed to the MPEG input document addressing the technical questions in this liaison (m32287). H2B2VS has contributed as well to a submission to JCTVT requesting to define a profile for the HEVC scalable extension supporting Color Gamut and Bit-depth Scalability (CGS). Such a scalability technology may be considered in applications standardization committees such as DVB CM-AVC/CM-UHDTV or ATSC3.0. Considering the foreseeable evolution of capture and display device capabilities and use cases, CGS appears to be one major feature to be supported in upcoming mainstream applications. Finally, this contribution also suggests to establish a Liaison Statement on Color Gamut Scalability requirements and performance between DVB CM-AVC/CM-UHDTV, SC 29/WG 11 and SG...read more
H2B2Vs continues to work with the MPEG standardization body to enable signaling and synchronization of external enhancements of programs carried over MPEG-2 Transport Stream. In particular the project’s proposal can be used to locate and synchronize external content with an MPEG-2 TS program, regardless of the external content packaging or coding types.read more
In contribution m30300 presented at the 105th MPEG Meeting in Vienna, H2B2VS submitted a follow-up on hybrid MPEG-2 TS/broadband delivery scenarios with suggested modifications to the existing working draft. The proposal includes a new syntax based on descriptors for future extensibility, a more compact representations of URLs, signaling of splicing points. The timing information has also been extended to carry SMPTE time codes and NTP timestamps.read more
The H2B2VS supported the initial technical proposal submitted by Telecom ParisTech and referenced “M29227 – Timeline Delivery for MPEG-2 TS enhancements”.
The project also contributed to this proposal by proposing Use Cases requiring such TS enhancements.
