Abstract: A method and system for delivering encoded content are provided. A holdback representing a portion of the encoded content is extracted, thereby damaging the encoded content. The damaged encoded content is distributed. The holdback is transmitted to enable reintegration of the holdback with the damaged encoded content to restore the encoded content.

Abstract: A system for modifying the output of individual bits of a fixed memory such as a ROM. Means are provided for recognizing the address of bit-locations requiring modification. The recognized addresses are organized into (a) those requiring the addition of a logic 1 bit or (b) those requiring deletion of a logic 1 bit. An output-data control package combines this information logically with the data bit existing in memory to provide a corrected data output bit on the required line of the ROM output bus. The system is also adaptable to "Word-oriented" ROM's such that an improper word in memory may be modified to provide a corrected output word from the ROM.
