Abstract
Abstract To provide a user with the capability of accessing audio/video material, and to remotely select, store and play back the material at any time, there is provided a receiving system responsive to a user input identifying a choice of an item stored in a source material library to be played back to the subscriber at a location remote from the source material library, the item containing information to be sent from a transmitter to the receiving system. The receiving system comprises transceiver means for automatically receiving the requested information from the transmitter as compressed formatted data blocks; receiver format conversion means coupled to the transceiver means; storage means coupled to the receiver format conversion means; decompressing means coupled to the receiver format conversion means; and output data conversion means coupled to the decompressing means for playing back the decompressed information in real time at a time specified by the user.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
155 words
A receiving system responsive to a user input identifying a choice of an
item stored in a source material library to be played back to the subscriber at a
location remote from the source material library, the item containing
information to be sent from a transmitter to the receiving system, the receiving
system comprising: transceiver means, for automatically receiving the requested information
from the transmitter as compressed formatted data blocks; receiver format conversion means, coupled to the transceiver means, for
converting the compressed formatted data blocks into a format suitable for
storage and processing for playback in real time; storage means, coupled to the receiver format conversion means, for
storing the compressed formatted data; decompressing means, coupled to the receiver format conversion means,
for decompressing the compressed formatted information; and output data conversion means, coupled to the decompressing means, for
playing back the decompressed information in real time at a time specified by
the user.
Claim 2
Dependent Claim
108 words
A digital audio/video communication network comprising: a local reception system comprising: means for receiving compressed, digitized data representing at least one
item of audio/video information at a non-real time rate, means for storing a complete copy of the received compressed, digitized
data, and means, responsive to the stored compressed, digitized data, for
transmitting a representation of the at least one item of audio/video information
at a real-time rate to at least one of a plurality of subscriber receiving stations
coupled to the local reception system, the at least one of the plurality of
subscriber receiving stations being located at a different physical location than
the local reception system.
Claim 3
Dependent Claim
33 words
A digital audio/video communication network as recited in claim 2,
wherein the means for transmitting comprises a converter for decompressing the
compressed digitized data representing the at least one item of audio/video
information.
