Abstract
An improved video recorder/transmitter with expanded functionality including a capability for editing and/or copying from one video tape to another using only a single tape deck. The increased functionality is realized through the use of analog to digital conversion, signal compression and intermediate storage in an integrated circuit, random access memory. The recorder/transmitter has capabilities to transmit and receive program information in either a compressed or decompressed format over fiber optic lines.
Claims80
An audio/video transceiver apparatus comprising:
- input means for receiving audio/visual source information;
- compression means, coupled to said input means, for compressing said audio/video source information into a time compressed representation thereof having an associated time period that is shorter than a time period associated with a real time representation of said audio/video source information;
- random access storage means, coupled to said compression means, for storing the time compressed representation of said audio/video source information;
- and
- output means, coupled to said random access storage means, for receiving the time compressed audio/video source information stored in said random access storage means for transmission away from said audio/video transceiver apparatus.
2 more elements
An audio/video transceiver apparatus as in claim 11 wherein said random access storage means comprises an optical disc.
An audio/video transceiver apparatus comprising:
- input means for receiving audio/video source information as a time compressed representation thereof, said time compressed representation of said audio/video source information being received over an associated burst time period that is shorter than a real time period associated with said audio/video source information;
- random access storage means, coupled to said input means, for storing the time compressed representation of said audio/video source information received by said input means;
- and
- output means, coupled to said random access storage means, for receiving the time compressed representation of said audio/video source information stored in said random access storage means for transmission away from said audio/video transceiver apparatus.
1 more element
An audio/video information transfer network comprising:
- a plurality of audio/video transceivers, coupled via one or more communication links, each of said audio/video transceivers comprising;
- input means for receiving audio/video source information;
- compression means, coupled to said input means, for compressing said audio/video source information into a time compressed representation thereof having an associated burst time period that is shorter than a time period associated with a real time representation of said audio/video source information;
- random access storage means, coupled to said compression means, for storing the time compressed representation of said audio/video source information;
- and
- output means, coupled to said random access storage means and to one of said one or more communications links, for receiving the time compressed format representation of said audio/video source information stored in said random access storage means for transmission in said burst time period to another one of said plurality of audio/video transceivers.
3 more elements
An audio/video transceiver apparatus comprising:
- input means for receiving analog and/or digital audio/video source information;
- analog to digital converter means for converting analog audio/video source information received at said input means to corresponding digital audio/video source information;
- digital to analog converter means for converting digital audio/video source information received at said input means to corresponding analog audio/video information;
- compressor/decompressor means for compressing digital audio/video source information received at said input means or said corresponding digital audio/video source information received from said analog to digital converter means into a time compressed representation of said digital or corresponding digital audio/video source information, said time compressed representation having an associated time period that is shorter than a time period associated with a real time representation of said digital or corresponding digital audio/video source information, said compressor/decompressor means being further operative for decompressing said time compressed representation into a decompressed real time representation of said digital or corresponding digital audio/video source information;
- central processing unit means for controlling operation of said compressor/decompressor means;
- random access storage means for storing said time compressed representation of said digital or corresponding digital audio/video source information and for storing said decompressed real time representation of said digital or corresponding digital audio/video source information;
- controller means for enabling communication between said compressor/decompressor means, said central processing unit means, and said random access memory means;
- and
- output means for receiving said time compressed representation of said digital or corresponding digital audio/video source information stored in said random access storage means for transmission away from said audio/video transceiver apparatus.
