Definitions

  • the presentation continues along the main presentation path without interruption.
  • the sidebar icon disappears, the interactive feature is disabled, and selecting the sidebar has no effect.
  • An aspect of our invention is a system, apparatus and method for preprocessing and delivering multimedia presentations to customers.
  • Our inventive system comprises a preprocessor, mass storage, a delivery processor, a distribution network, and a plurality of presentation processors.
  • the preprocessor receives as inputs an OMP, which includes presentation commands and associated objects, and presentation technology parameters (PTPs) indicating key information about the delivery processor, the distribution network, and the presentation processor which are to deliver and present the presentation to a requesting customer.
  • This key information includes the round trip latency (RTL) between the delivery processor and the presentation processor, which RTL is the time for a 1 bit message to be sent from the presentation processor to the delivery processor and a response from the delivery processor to be received at the presentation processor.
  • RTL round trip latency
  • Fig. 5 depicts an illustrative embodiment of our presentation processor in accordance with an aspect of our invention.
  • Fig. 6A depicts a table of the delivery times of preprocessed multimedia presentation corresponding to the original multimedia presentation of Figs. IB and IC, in accordance with an aspect of our invention.
  • This key information includes the round trip latency (RTL) between the delivery processor and the presentation processor, which RTL is the time for a 1 bit message to be sent from the presentation processor to the delivery processor and a response from the delivery processor to be received at the presentation processor.
  • RTL round trip latency
  • the PTPs also include the bit rate of distribution network and the memory capacity of the presentation processor. Based upon these inputs, the preprocessor generates a PMP.
  • the presentation scheduler 205 may cause the message generator 207 to report an error and may halt the preprocessing operation.
  • the PTP generator may also request and receive from the distribution network its network bit rate, and from the presentation processor, via interface 404, its memory capacity, thereby permitting the preprocessor to retrieve all PTPs from the PTP generator 407 in lieu of having to communicate directly with the distribution network and presentation processor. On being prompted by the preprocessor for PTPs, the PTP generator sends, via interface 405, the PTPs requested.
  • RTL round trip latency
  • the presentation scheduler also includes in the delivery schedule lead 223, labelled 1 and connecting Nodes 3 and 5, to accommodate the case where a message indicating the customer's selection is received at the delivery processor (Step 843). If there were other objects to be presented on the interactive feature being selected, they also would have been similarly scheduled for delivery (Step 844).
  • the presentation processor includes in the delivery schedule a return (R) node which is connected to Node 5 via lead 231, labelled 0 (Step 845).
  • the return node contains instructions for the delivery processor to return in the delivery schedule to the point prior to the current node, which point would be at Node 3.
  • the presentation scheduler includes in the delivery schedule, another lead from Node 3, lead 224. This lead is labelled 0, and accommodates the case where no message indicating the customer's selection is received at the presentation scheduler after delivery of Object 6.
  • the presentation scheduler tracks the available memory at the presentation processor at memory counter 206, which would indicate 200 Kbytes of available memory after Object 3 is delivered.
  • Object 4 is scheduled in a manner similar to Object 3, resulting in lead 225, labelled 0, connecting Nodes 4 and 6.
  • customer 600-1 requests the multimedia presentation depicted in Figs. IB and IC.
  • This request is received at the customer store 606 of the presentation processor via the distribution network 500 and interface 602 of the presentation processor 600.
  • This request is detected by the presentation controller 608 and transmitted to the delivery processor 400.
  • the request is received at interface 402 and detected by the delivery controller 401.
  • the delivery processor retrieves from mass storage 300 the PMP which has been optimized for delivery over a distribution network and to a presentation processor having certain minimal characteristics (Step 861 of Fig. 8).

Abstract

Un système de prétraitement et d'acheminement de présentations multimédia à des clients (601) permettant d'éliminer pratiquement le temps de réponse d'interaction, comprend un préprocesseur (200), une mémoire de grande capacité (300), un processeur d'acheminement (400), un réseau de distribution (500) et une pluralité de processeurs de présentation (600). Le préprocesseur (200) reçoit en tant qu'entrées une présentation multimédia originelle et des paramètres caractérisant les autres composantes du système. Parmi ces paramètres, il y a la latence causée par l'aller et le retour entre le processeur d'acheminement (400) et le processeur de présentation (600). Le préprocesseur (200) génère une présentation multimédia prétraitée comprenant un programme d'acheminement sous la forme d'un graphe orienté et étiqueté. Lorsqu'il génère le programme d'acheminement, le préprocesseur (200) vérifie que chaque objet de la présentation et sa commande de présentation associée arrivent au processeur de présentation (600) pas plus tard que son temps de présentation.
