Abstract

A sender-subscriber based, transmission traffic control system for video mail, which includes the transmission of bulk electronic data primarily in the form of still or motion picture images, with or without audio track. There are variable bandwidth controls on a per transmission basis. A delivery network system provider often a subscriber service in which the network has absolute control over the actual time of the video mail transmission. The path, bandwidth allocation, protocol format, and other means of transmission--such as wireless, satellite, analog--can be set at the discretion of the network provider. The system can provide transmission data, such as delivery and receipt notification to each sender-subscriber, each recipient, and all other participating transmission agents and networks that are different from the managing network delivery system.

Claims

1. A method of transmitting bulk data with a component in the form of still or motion picture images from at least one sender to at least one receiver under the control of a managing network provider, the method comprising executing on a per transmission basis the following steps:

a) each sender identifying intended receivers to the managing network provider and the duration or size of an intended transmission of data,

b) the managing network provider checks data transmission traffic over a virtual transmission path between each sender and each identified receiver to determine appropriate transmission times,

c) the managing network provider provides a scheduled transmission time to each sender,

d) the managing network provider sets up each control point along the virtual transmission path to each identified receiver for the scheduled transmission time, and

e) each sender transmits the bulk data at the scheduled time through the virtual transmission path to each identified receiver.

2. A method of video mail transmission, defined as a transmission of bulk electronic data with a component in the form of still or motion picture images, with or without audio track, the method comprising the following steps being executed on a per transmission basis between each sender and a managing network provider, being a PSTN, cable company or private network that assumes all control over the transmission and network setup, with each sender'"'"'s involvement reduced to simply inputting the video mail transmission at a network designated time:

(a) each sender initiating the method by first calling the office of the managing network provider, and specifying the telephone numbers or network node address of each receiver of the intended video mail transmission and the duration or size of the intended transmission;

(b) each sender also specifying minimum picture quality and desired encryption of the intended transmission, and whether the receipt of the transmission should be registered or reported by each recipient;

(c) the managing network provider then checking existing and scheduled video mail transmission traffic between each sender and each identified recipient, to determine appropriate transmission times, taking into account all possible bandwidth and transmission controls known to the network that can provide a transmission capability to fully transmit the video mail transmission, and would also optimize available network bandwidth and transmission capabilities for other potential video mail traffic;

(d) the managing network provider announcing one or several optional transmission times to each sender;

(e) the managing network informing all potential agent networks, and all transmission control points along the transmission paths between each sender and each identified recipient of the agreed to time and data communication requirements of the intended video mail transmission, and hence, setting all control points, either through its own operators or the operators of agent networks, and informing all such agents of the pending transmission immediately before calling each sender to instruct each sender to initiate the transmission;

(f) the managing network calling each sender, each sender initiating the video mail transmission at a transmission time designated by the managing network, and then transmitting the video mail to each receiver designated by each sender;

(g) the managing network, if requested to do so by each sender, obtaining a documented confirmation of receipt of the entire video mail transmission from each receiver designated by each sender.

3. The method of claim 2, further comprising a method of transmission-time-flexible video mail delivery along a virtual transmission path, herein defined as a set of transmission controls along a transmission path from each sender to each identified receiver of the video signal transmission, wherein the transmission time, transmission speed, route, encryption, compression, modulation, protocol format, transmission devices and route, RF frequency band, and scale or size of digital bandwidth window for the transmission can be preemptively scheduled and determined by a managing network provider on a per transmission basis, according to these controls, because transmission time and virtual transmission path controls, and whereby all video mail traffic, are independent of each video mail sender,

said video mail delivery, being controlled and transmitted on a per transmission basis, can be reported with certainty, and guaranteed to each sender or subscriber, and all receivers, being either end receivers or multimedia merging processors, of the video mail,

said video mail delivery, being controlled and transmitted on a per transmission basis, enables the notification of all other agent network providers or transmission entities both locally, and at all effective control points along the virtual transmission path of the exact time and period of each anticipated video mail transmission, in order to guarantee an adequate bandwidth window for each said video mail transmission along each time determined virtual transmission path.

4. The method of claim 2, operating on a telecommunication system involving one or several public or private switched telephone, computer, cable, satellite or wireless agent networks or transmission enabling entities, on a per transmission basis, to provide video mail transmissions from each sender-subscriber'"'"'s premises to each identified receiver premises,

said telecommunication system managed by a managing network provider, which may be one of the aforementioned networks said telecommunication system comprising:

one or several managing network provider, or agent network provider offices, or points of presence of the managing network provider, receiving digital or analog video signals from local sender-subscribers as well as orders regarding the delivery of video mail and any requests of notification of successful delivery from sender-subscribers, and one or several offices, local to recipients, routing the video mail to receivers locally, said receiving local offices including a video mail gateway, being potentially the first control point of any virtual transmission path to each and every receiver,

said virtual transmission path being controlled specifically for any video mail transmissions by the managing network provider'"'"'s operators or transmission control system,

said operators or transmission control system also providing, on occasion, similar virtual path controls over video mail received from each sender-subscriber at the local office video mail transmission interface to the video mail gateway, such as RF band or acceptance bandwidth;

an office interface for each sender-subscriber or video mail receiver, including an operator, voice, data or voice and data interactive system to obtain necessary information about each sender-subscriber'"'"'s video information and then to inform each sender-subscriber as to when the transmission will take place, another interface to handle the reception of each sender-subscriber'"'"'s video mail, in one or more of the following transmission forms, satellite downlink, digital wireless or analog RF wireless or coaxial transmission, digital optical fibre, digital coaxial or digital telephone line transmission, a similar operator or interactive interface and one or more of said video mail interface capabilities also being included at an office local to each identified receiver;

each said sender-subscriber premises including the means of transmitting the video mail to the local office, which may include a video camera, image digitizer or scanner, television, VCR, video network server or video computer system, video telephone, satellite uplink, digital wireless modem or RF analog signal transmitter;

transmission interface multiplexer or digital encoder for an optical fibre or coaxial cable link to the nearest local office, or a line provided by a telephone company with sufficient bandwidth to transmit video of an accepted picture information quality for each sender-subscriber,

said means of transmission can also include digital compression or modulation capabilities at each sender-subscriber'"'"'s premises;

each said receiver premises receiving each sender-subscriber'"'"'s video mail, which is controlled by the managing network'"'"'s transmission control, including the means of receiving the video mail, which may include a video telephone, television, VCR, video network server or video computer system, satellite downlink, digital wireless modem or RF analog signal transmitter;

transmission interface multiplexer or digital encoder for an optical fibre or coaxial cable link to the nearest local office, or a line provided by a telephone company with sufficient bandwidth to receive video of the originally transmitted picture information quality or an accepted picture information quality determined by the bandwidth between a receiver and a local office,

said means of receiving the video mail can also include digital decompression or demodulation capabilities at the receiver'"'"'s premises.

5. The method of claim 2, further comprising a method by which the managing network provider may with liberty through its own telecommunication system or through the telecommunication systems of agent networks, on a per transmission basis, at any control point along any virtual transmission path, convert the video mail transmission from analog to digital formats, compress and decompress the message using digital methods of video and audio compression, or use any digital modulation techniques to squeeze more bandwidth onto a single RF carrier, encrypt the message, convert the video mail transmission at any point from one to any other digital communication protocol, determine the period of usage and frequency of the band for digital wireless or analog RF transmission, determine the period of transponder access on a satellite to enable a satellite uplink for the transmission, or provide these latter two capabilities to each sender-subscriber directly for the local leg of the video mail transmission, from each sender-subscriber to a local office, before the first control point, as well as at any control point along the virtual transmission path thereafter.

6. The method of claim 2, further comprising a method by which a single or network of video mailbox systems, each consisting of a computer or microprocessor, and a computer memory capability to store database information, may be used by the managing network provider to schedule, at any control point along the virtual transmission path, the necessary bandwidth, protocol formats and routing of every video mail transmission on a per transmission basis,

said video mailbox database storing said database information per transmission as each senders'"'"' and all recipients'"'"' video mail transmission telephone or network node addresses, transmission time, duration, input picture information quality or format, requested message encryption, identified receivers'"'"' names and addresses for documented receipt, and such control point information per transmission path from each sender to each identified receiver as available switch/router protocol translation processors, compression/decompression and modulation/demodulation processors, agent network bridges, encryption processors, bandwidth scaling processors, analog to digital conversion interfaces, satellite transmission interfaces and wireless transmission interfaces, and any other network control information pertaining to the routing and scheduling of an adequate transmission path, based on an assessment of adequate bandwidth window provided by all necessary control points between each sender and each identified receiver.
