English

Subject field(s)
  • Informatics

  • Collaboration with WIPO
CONT

High Efficiency Video Coding(HEVC)... is a draft video compression standard, a successor to H. 264/MPEG-4 AVC(Advanced Video Coding), currently under joint development by the ISO/IEC [International Electrotechnical Commission] Moving Picture Experts Group(MPEG) and ITU [International Telecommunication Union]-T Video Coding Experts Group(VCEG). MPEG and VCEG have established a Joint Collaborative Team on Video Coding(JCT-VC) to develop the HEVC standard. HEVC improves video quality and doubles the data compression ratio compared to H. 264, and scales from 320 240 to 7680 4320 pixels resolution.

OBS

high efficiency video coding; HEVC: data validated by Canadian subject-field experts from École Polytechnique de Montréal, MasterpieceVR and McGill University.

  • Collaboration avec l'OMPI
CONT

Le domaine de l'invention est celui du codage et du décodage d'images ou de séquences d'images, et notamment de flux vidéo. Plus précisément, l'invention concerne la compression d'images ou de séquences d'images utilisant une représentation par blocs des images. L'invention peut notamment s'appliquer au codage vidéo mis en œuvre dans les codeurs vidéo actuels (MPEG, H.264, etc. et leurs amendements) ou à venir (ITU-T/ISO HEVC, en anglais «High-Efficiency Video Coding» pour codage vidéo à haute efficacité), et au décodage correspondant.

CONT

[…] el ISO/IEC MPEG (Grupo de Expertos de Imágenes en Movimiento) y ITU-T VCEG (Grupo de Expertos de Codificación de Video) crearon el formato de compresión de video H.265 o HEVC (codificación de video de alta eficiencia) que, según [el Sector de Normalización de las Telecomunicaciones de la Unión Internacional de Telecomunicaciones, UIT-T] permite reducir la razón de bit con respecto al formato de compresión H.264 […] No obstante, llevar a cabo el proceso de compresión del video de alta definición empleando codificación H.265 es una tarea que requiere un alto nivel de procesamiento.

CONT

El estándar HEVC ("High Efficiency Video Coding" por sus siglas en inglés) introduce nuevos elementos y técnicas en las diferentes etapas del codificador/decodificador, con el objetivo de conseguir mejoras significativas en la eficiencia de compresión.

Subject field(s)
  • Engineering Tests and Reliability
DEF

Risk of the EUC and its control system (providing it is not a designated safety-related system) and associated human factor issues.

OBS

The main purpose of determining the EUC risk is to establish a reference point for the risk without taking into account safety-related systems and external risk reduction facilities.

Record 47 1995-11-22

English

Subject field(s)
  • Engineering Tests and Reliability
DEF

A protection system designed to respond to conditions on the EUC, which may be hazardous in themselves, or if no action were taken, could give rise to hazardous events, and to generate the correct outputs to mitigate the hazardous consequences or prevent the hazardous events.

OBS

In many cases the correct response of the protection system would be to bring all processes or movements to a predetermined safe state; in others the correct response may be more complex e.g. involving an ordered shutdown or start-up of equipment. The correct response may depend on the state of the EUC.

Subject field(s)
  • Statutes and Regulations (Air Transport)
CONT

The general thrust of the new ICAO draft is to establish a threshold of 60 minutes’ flying time at single-engine speed from an alternate, beyond which twins may not operate unless they have demonstrated a certain standard of powerplant reliability and systems redundancy. Existing rules date from the late 1940s and are recognised to be outmoded in the light of current technology. ICAO's provision does not specifically mention turns, but has the effect of preventing them from operating more than 90 minutes’ flying time(with both engines operating) from an alternate-the so-called "90-minute rule".

Key term(s)
  • ninety minute rule

  • Réglementation et législation (Transp. aérien)
CONT

Le projet de l'OACI se fonde sur la notion de "seuil" d'éloignement maximal d'un terrain de déroutement (60 minutes de vol à la vitesse de croisière sur un moteur), seuil que les bimoteurs ne pourront franchir qu'à la condition d'avoir fait la preuve d'un certain degré de fiabilité de leurs groupes propulseurs et de redondance de leurs systèmes. Les règles actuelles datent de la fin des années 1940 et tout le monde reconnaît qu'elles sont dépassées. Le projet de l'OACI ne mentionne pas spécifiquement les bimoteurs, mais il a pour effet que ceux-ci ne devront jamais se trouver à un moment quelconque à plus de 90 minutes de vol (sur deux moteurs) d'un terrain de dégagement. C'est ce que l'on appelle "la règle des 90 minutes".
