Abstract

A method for conditioning multimedia containers to be compatible with decoding facilities of receivers of diverse types is disclosed. Content of a multimedia container may include components of different encoding formats. Container conditioning also detects and, where feasible, removes undesirable insertions within each content component of a multimedia container. A content component of a container may be filtered, re-encoded, or deleted. Notifications indicating conditions of a container and any modifications performed are appended to the container. A notification may be presented in at least one form compatible with characteristics of a respective receiver. An editing engine implementing the method is associated with a network entity to which multimedia containers are directed. The editing engine accesses a receiver database storing information on several types of receivers and a repository of notification templates encoded in several forms.

subject to a determination of incompatibility, decode a content component to produce a decoded content component and re-encode said decoded content component to a form compatible with said receiver type.

7. The system of claim 1 further comprising

a module for merging notifications with respective data containers.

8. The system of claim 1 further comprising a transmitter-notification module for sending said notifications to respective transmitters.

9. The system of claim 1 further comprising at least one memory device organized into multiple virtual queues, each virtual queue corresponding to a respective condition type.

separating incoming data containers from received data;

directing said incoming data containers to a respective container conditioner;

receiving processed data containers from said respective container conditioner; and

directing said processed data containers to a switching fabric of said switching node for switching to respective receivers.

11. The method of claim 10 further comprising configuring said respective container conditioner to perform processes of:
