Este trabajo ha considerado diferentes esquemas de metadatos, extensiones y perfiles de aplicacion que pueden ser utilizados en la industria de la television digital, tales como, SMEF, MXF Metadata Eschema, MPEG-7
, EgtaMeta, entre otros, sin embargo, se describen los mas destacados y vigentes: MPEG7, TVAnytime, P-META, EBUCore, PBCore y SMPTE Metadata Element Dictionary Structure.
The main objective of CustomTV is to develop, demonstrate and validate the technology for user-friendly screen customisation and interactive programme selection in a multimedia broadcast environment by introducing the multimedia elements of the MPEG-4 standard and the object description of the MPEG-7
standard into existing Digital Visual Broadcasting (DVB) services.
Some of the topics are: MPEG standards in media production, broadcasting, and content management; using MPEG tools in video summarization; encryption techniques for H.264 video, image clustering and retrieval with MPEG-7
, and MPEG-A and its open access application format.
The MPEG Query Format (MPQF) is Part 12 of ISO/IEC 1593812, "Information Technology -Multimedia Content Description Interface", better known as MPEG-7
. The standardization process in this area started in 20th06, and MPQF became an ISO/ IEC final standard after the 85th MPEG meeting in July 2008.
Our approach is based on structured peer-to peer networks and allows complex queries using standard MPEG-7
and MPEG-21 multimedia metadata.
audio and beyond; audio content indexing and retrieval.
The NEC Corporation, a broadband, internet, network provider and the Samsung Advanced Institute of Technology (SAIT), a product research facility, have announced that their jointly proposed new face recognition technology has been adopted for the MPEG-7
standard to be published in the spring of 2004.
XML Schemas have been used to define metadata schemas for a number of specific domains or applications--such as METS (Library of Congress, 2003), MPEG-7
(Martinez, 2002), MPEG-21 (Bormans & Hill, 2002), and NewsML (IPTC, 2001).
Moving onto his conference on MPEG compression -- the "heart" of any digital TV device -- Chiariglione said that the committee jumped from MPEG-4 to MPEG-7
to 21 because "when we jump, we jump big." Chiariglione further explained that MPEG-4 is for Internet, MPEG-7
makes contents "searchable" and MPEG-2 1, an open universal system, is the solution for digital TV.
Domain-specific ontologies have been developed by two different ISO Working Groups to standardize the semantics associated with the description of museum objects (CIDOC Conceptual Reference Model) and the description of multimedia content (MPEG-7
), but no single ontology or metadata model exists for describing museum multimedia content.
NIST actively participated in the development of the MPEG-7
Multimedia Content Description Interface standard, which was released at the Moving Picture Experts Group (MPEG) meeting in Thailand in December 2001.
The author presents several international norms related to video compression such as JPEG, H.261, H.263 and MPEG-1, MPEG-2, MPEG-4 and MPEG-7
. Audio coding techniques are also presented, along with techniques based on wavelets and vector quantization.
