Vector quantization is a generalization of the scalar quantization method... It is used for both image and audio compression. In practice, vector quantization is commonly used to compress data that has been digitized from an analog source, such as audio samples and scanned images.  5, record 1, English, - vector%20quantization

Technique de quantification souvent utilisée dans la compression de données avec pertes de données [...] pour laquelle l'idée de base est de coder ou de remplacer par une clé des valeurs d'un espace vectoriel multidimensionnel vers des valeurs d'un sous-espace discret de plus petite dimension.  3, record 1, French, - quantification%20vectorielle

The utilization of the inactivity periods that always exist in both transmission directions of a telephone conversation. The interpolation is used in order to increase the efficiency and lower the cost of long distance links. Analog signals with quiescent periods or long vowels are compressed, for example by time assignment speech interpolation, transmitted, and expanded by inverse compression(expansion) at the receiving end. This principle... is now being developed for digital speech [and] when pulse code modulation is used, the process is known as digital speech interpolation.  1, record 2, English, - analog%20speech%20interpolation

Le signal vidéo contenu dans un DVD par exemple, est encodé et stocké en composantes vidéo (Y/Cr/Cb). Chacune de ces trois données est quantifiée en 8 bits. Le premier travail consiste à requantifier les données en 10 bits, [à] extraire le signal composite, Y/C (S-Vidéo) et RVB (suivant les modèles) et [à] le convertir en données analogiques exploitables par les matériels et ce en utilisant un convertisseur D/A 10 bits.  4, record 3, French, - convertisseur%20vid%C3%A9o%20num%C3%A9rique%2Danalogique

Although real motion video is the holy grail of multimedia, it still is impractical using today's technology. The current method for working with video is by capturing and converting the analog signal from a video source and either manipulating the image's data(which is written to video tape) or compressing the data using compression techniques(either software-only compression or a combination of hardware and software compression). To display or capture a single screen of an NTSC [National Television System Committee] signal, you must have a video frame grabber.... Real-time frame grabbers capture full-motion video at a rate between 15 and 30 frames-per-second using video compression...  4, record 4, English, - full%2Dmotion%20video

Le CD-I fait appel à des techniques très sophistiquées de compression d'images pour pouvoir stocker des images animées, très consommatrices d'espace. L'algorithme de compression est baptisé «Full Motion Video» (FMV). C'est la mise au point de cet algorithme qui a permis au CD-I de pouvoir afficher jusqu'à 72 minutes d'images animées plein écran. La qualité de l'image ainsi traitée est équivalente à celle d'un magnétoscope VHS mais inférieure à celle d'un LaserDisc.  4, record 4, French, - vid%C3%A9o%20plein%20%C3%A9cran

Grâce à une carte d'acquisition vidéo, il devient possible de capturer des séquences issues d'un magnétoscope ou d'un caméscope [...] Les cartes d'acquisition ont pour fonction de numériser les images analogiques. Cette numérisation doit se faire en temps réel. L'objectif est donc d'acquérir, de numériser, de compresser et de stocker sur disque 25 images à la seconde. Bien sûr, toutes les cartes n'offrent pas ces performances.  4, record 5, French, - carte%20d%27acquisition%20vid%C3%A9o

These are lowest on the rungs of the video ladder, in that they have less capability than boards that capture streaming video. These cards enable you to grab a single frame of video from a Laser Disk or a VCR. Video frame grabbers come in two varieties : single-frame capture and real-time capture. Single-frame capture boards enable you to freeze a selected frame and record it to your hard disk. In this function, single-frame boards are similar to scanners-they provide a means of capturing an image and saving it for use in a multimedia title....
