1. A method of providing items of audiovisual information from a transmitter to a receiving system remote from the transmitter, the method comprising:

  • time encoding video digital data blocks by assigning first relative time markers to the video digital data blocks, the video digital data blocks including video information from an audiovisual item;

    time encoding audio digital data blocks by assigning second relative time markers to the audio digital data blocks, the audio digital data blocks including audio information from the audiovisual item;

    wherein the first relative time markers and the second relative time markers allow for realignment of the video digital data blocks and the audio digital data blocks for the audiovisual item;

    compressing the video digital data blocks assigned the first relative time markers using a compression method;

    wherein the compression method includes use of a discrete cosine transformation and motion compensation;

    compressing the audio digital data blocks assigned the second relative time markers;

    placing the compressed video digital data blocks, the compressed audio digital data blocks, the first relative time markers, and the second relative time markers into a file for the audiovisual item;

    storing the file for the audiovisual item on a storage device;

    wherein the storage device stores a file containing compressed video digital data blocks, compressed audio digital data blocks, first relative time markers and second relative time markers for each of a plurality of audiovisual items, the plurality of items including the audiovisual item;

    receiving a request for one of the plurality of items;

    wherein the request is received from the receiving system over a communication channel;

    wherein the request is generated using a user terminal interface;

    wherein the request includes an address of the receiving system;

    wherein the request additionally includes an address associated with the requested audiovisual item; and
