Definitions

  • This invention relates to a method of, and to a system for, the dissemination of information and, more particularly, but not exclusively, to a method of, and to a system for, the dissemination of promotional or advertising mate ⁇ al and the iike.
  • an advertiser wishing to disseminate advertising mate ⁇ al by means of a video signal will purchase advertising space from a broadcaster or an operator of a television network.
  • advertising space is generally purchased in units of time, so that an advertiser may, for example, purchase sufficient advertising space to flight a 30 second video program containing his advertising or promotional material
  • the price of the advertising space is dependent on the viewership which is reached by the broadcast, and is dependent on factors such as time of day, number of subscribers or viewers, and so forth.
  • This method of dissemination of information is disadvantageous as the advertising space is expensive and unaffordable by many advertisers Further, the cost of producing video programs for advertising is expensive, and the use of video for the dissemination of static promotional or advertising mate ⁇ al is unnecessa ⁇ ly inefficient and costly
  • Video signals are commonly employed for the presentation of full motion visual info ⁇ mation and consist of a continuous and regular sequence of video frames, each representing a target image
  • the human visual system requires a finite time to process or interpret an image
  • the processing time is a function of the amount of detail contained in the image
  • a standard sequence of related video frames representing a moving target image will be easily interpreted by a viewer as each frame contains little new detail to be interpreted by the viewer relative to the preceding frame
  • the human cognitive system will find it impossible to interpret all of the information in each frame, since the viewing time for each individual frame will be too short
  • the effective viewing time of the information is increased, thereby allowing the human visual system to interpret the information.
  • info burst It is known to broadcast a sequence of video frames at a standard frame rate where the frames of the sequence represent information which is uni ⁇ terpretable by a viewer when viewed at the standard frame rate. Such transmission is sometimes referred to as "info burst".
  • info burst broadcast signal is typically recorded by a viewer and the recorded frames are then replayed at a slower frame rate which is sufficiently slow to allow interpretation of the recorded frames by the viewer.
  • This system is disadvantageous in that the information contained in a particular frame is only intelligible by means of a linear sequential scan through the recorded frames at the slower frame rate.
  • British Patent No. GB2.129.649 discloses a system for dissemination of information in which individual frames of an info burst video broadcast signal are indexed.
  • the individual frames of the broadcast signal are supplied to an index generator at a standard broadcast frame rate.
  • the index generator inserts indexing information on each frame, in the form of page numbers, other alphanumeric characters, colours, borders and the like, which is incremented or decremented in response to a control signal.
  • a shortcoming of this system is a lack of synchronisation between frame changes of the broadcast signal and the control signal which increments or decrements the indexing information. Further, this type of indexing is unpractical for use in applications where multi-level indexing is required.
  • Frames of analogue video signals are encoded by a video camera, transmitted and reconstructed at a receiver as two interlaced fields, known in the art as the "A" and "B" fields Each of these underlying fields contains half of the image information represented in the video frame If only one field of the frame is displayed the resultant image, although imperfect, is still interpretable by a viewer thereof

Abstract

L'invention concerne un système destiné à la diffusion d'informations, comportant une unité d'accès utilisateur, une unité de traitement, et une unité de comptabilisation. L'unité d'accès utilisateur permet à un utilisateur du système de soumettre des informations pour la diffusion, et l'unité de traitement convertit les informations soumises en un certain nombre de pages de données numériques séparées. Le système comporte des moyens de compilation destinés à compiler une sélection des pages de données numériques en fonction d'un critère de sélection prédéterminé, et des moyens de conversion destinés à créer un signal de sortie vidéo transmissible contenant un certain nombre d'images vidéo fixes ne pouvant pas être interprétées par un utilisateur à un taux de diffusion d'images standard. Chaque image vidéo fixe du signal de sortie vidéo correspond à une des pages de données numériques dans la sélection compilée. L'unité de comptabilisation comptabilise l'utilisateur du système en tant que fonction du nombre d'images vidéo fixes comprises dans le signal de sortie vidéo.
