Claim 1
Independent Claim 125 words
A distribution method responsive to requests identifying information to be sent from a transmission system (100) to remote locations (200), the method comprising the steps of: storing, in the transmission system, audio and video information as files (413e) in a compressed sequenced data form; requesting transmission (415), by a user, of at least a part of the stored compressed sequenced data to a remote location selected by the user; sending (416) at least a portion of the stored compressed sequenced data to the remote location; receiving (417) the sent data at the remote location; buffering (419) the received data at the remote location; decompressing (205) the buffered data; and playing back the decompressed data in real time at a time requested by the user (419).
Claim 2
Dependent Claim 17 words
The distribution method of claim 1 wherein the files are stored on a mass storage device (118).
Claim 3
Dependent Claim 19 words
The distribution method of claim 1 wherein the files are stored on a network of mass storage devices (118).
Claim 4
Dependent Claim 50 words
The distribution method of claim 1 further comprising receiving, at the transmission system (100), a request from a user for a list of items available that match a search criteria and providing a responsive list to the user so that the user may remotely request a particular item for transmission.
Claim 5
Dependent Claim 68 words
The distribution method of any of claims 1 to 4 wherein the information includes analog and digital signals, and wherein the step of storing comprises the steps of: converting (123) analog signals of the information to digital components; formatting (125) the digital data signals of the information; ordering (114) the converted analog data and the formatted digital data in a predetermined sequence; and compressing (115, 116) the information.
Claim 6
Dependent Claim 34 words
The distribution method of any of claims 1 to 5 wherein the step of storing information items includes the substep of storing the items in a plurality of compressed picture and sound information blocks.
