Abstract
Abstract Video on Demand allows, for example, a coded TV signal or film to be transmitted to a subscriber over a standard two-wire metallic telephone line. A similar apparatus for connecting unidirectional mobile data output to a destination via a standard metallic telephone line, the apparatus comprising a High Bandwidth Subscriber Link Transmitter Unit connected between the data source and a connection point on the telephone line and a High Bandwidth Subscriber Link Receiver Unit connected to a further connection point on the telephone line would enable a signal such as from a video camera to be input at or subscriber terminal and transmitted over a metallic telephone line.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
A video reporting system for enabling a real-time, unidirectional, data transmission of high-bandwidth video data signals over a metallic telephone line to an intermediate destination before or at the input to a telephone exchange connected thereto, said signals being from a mobile video data source that is movable to said intermediate destination, said system comprising: a) a high-bandwidth subscriber link transmitter unit connected between the mobile source and a first telephone subscriber connection point on the telephone line; b) a high-bandwidth subscriber link receiver unit connected at said intermediate destination; and c) means at the first connection point, for accessing the receiver unit to establish a high-bandwidth connection for the data signals between said intermediate destination and a further destination.
Claim 2
Dependent Claim
120 words
A video reporting system for enabling a real-time, unidirectional, data transmission of high-bandwidth video data signals over a metallic telephone line to an intermediate destination before or at the input to a telephone exchange connected thereto, said signals being from a mobile video data source that is movable to said intermediate destination, said system comprising: a) a high-bandwidth subscriber link transmitter unit connected between the mobile source and a first telephone subscriber connection point on the telephone line; b) a high-bandwidth subscriber link receiver unit connected at said intermediate destination; and c) means at the first connection point, for accessing the receiver unit to establish a high-bandwidth connection for the data signals between said intermediate destination and a further destination.
Claim 3
Independent Claim
120 words
A method of enabling a real-time, unidirectional, data transmission of high-bandwidth video data signals over a metallic telephone line to an intermediate destination before or at the input to a telephone exchange connected thereto, said signals being from a mobile video data source that is movable relative to the destination, said method comprising the steps of: a) connecting a high-bandwidth subscriber link transmitter unit between the mobile source and a first telephone subscriber connection point on the telephone line; b) connecting a high-bandwidth subscriber link receiver unit connected at said intermediate destination; and c) accessing at the first connection point, the receiver unit to establish a high-bandwidth connection of the data signals between said intermediate destination and a further destination.
Claim 4
Independent Claim
120 words
A method of enabling a real-time, unidirectional, data transmission of high-bandwidth video data signals over a metallic telephone line to an intermediate destination before or at the input to a telephone exchange connected thereto, said signals being from a mobile video data source that is movable relative to the destination, said method comprising the steps of: a) connecting a high-bandwidth subscriber link transmitter unit between the mobile source and a first telephone subscriber connection point on the telephone line; b) connecting a high-bandwidth subscriber link receiver unit connected at said intermediate destination; and c) accessing at the first connection point, the receiver unit to establish a high-bandwidth connection of the data signals between said intermediate destination and a further destination.
Claim 5
Dependent Claim
22 words
The video reporting system of claim 1, wherein the transmitter unit and the receiver unit include an asymmetric digital subscriber link card.
Claim 6
Dependent Claim
14 words
The video reporting system of claim 3, wherein the transmitter unit includes a coder-decoder.
Claim 7
Dependent Claim
49 words
The video reporting system of claim 4, wherein the transmitter unit includes a housing in which the link card and the coder-decoder are mounted; wherein the housing has a telephone connector; and wherein the accessing means includes a telephone having a telephone wire for plugging into the telephone connector.
Claim 8
Dependent Claim
37 words
The video reporting system of claim 5, wherein the housing has an input port connected to the coder-decoder, and wherein the data source is a field-portable video camera having a wire for plugging into said input port.
Claim 9
Dependent Claim
28 words
The video reporting system of claim 1, and further comprising a test line connected to said exchange; and wherein the receiver unit is connected on the test line.
Claim 10
Dependent Claim
36 words
The video reporting system of claim 1, and further comprising a telephone concentrator on the telephone line, and a test line connected to said concentrator; and wherein the receiver unit is connected on the test line.
Claim 11
Dependent Claim
29 words
The video reporting system of claim 1, wherein the high-bandwidth connection extends over a telephone network having a data transmission rate on the order of two megabits per second.
