Abstract
Abstract In a video system incoming video having a given frame size is sent over a video transmission system that supports a different frame size. When a transmitting terminal in the transmission system receives the incoming video, the terminal does not scale the video to fit the transmitted frame size. Instead, the video compression encoder only encodes and sends the data associated with the incoming video. The encoder does not encode or send the rest of the standard transmitted frame. At a receiving terminal in the transmission system, all of the received data is decoded. However, because the decoded data will correspond to the original incoming frame size, this data, rather than the entire transmitted frame, is scaled to match the size of the display or the target window.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
129 words
A method for transmitting a video signal of a first format via a communication protocol for a second format, said method comprising: mapping data elements from a first data array representing a portion of a frame of the video signal of the first format into a second data array representing a portion of a frame of a video signal of the second format, wherein the number of rows and columns in the second data array is equal to or greater than the number of rows and columns in the first data array; setting to an arbitrary value each element in the second data array which does not correspond to an element in the first array; and transmitting the second array according to the communication protocol for the second format.
Claim 2
Independent Claim
129 words
A method for transmitting a video signal of a first format via a communication protocol for a second format, said method comprising: mapping data elements from a first data array representing a portion of a frame of the video signal of the first format into a second data array representing a portion of a frame of a video signal of the second format, wherein the number of rows and columns in the second data array is equal to or greater than the number of rows and columns in the first data array; setting to an arbitrary value each element in the second data array which does not correspond to an element in the first array; and transmitting the second array according to the communication protocol for the second format.
Claim 3
Dependent Claim
17 words
The method according to claim 1 , further comprising the step of receiving the second data array.
Claim 4
Dependent Claim
29 words
The method according to claim 2 , further comprising decoding into a video image data elements in the second data array corresponding to data elements in the first array.
Claim 5
Dependent Claim
22 words
The method according to claim 3 , further comprising scaling the decoded video image according to a size of a display media.
Claim 6
Dependent Claim
18 words
The method according to claim 4 , wherein the display media comprises a window on a display screen.
Claim 7
Dependent Claim
14 words
The method according to claim 1 , wherein the first video format is NTSC.
Claim 8
Dependent Claim
14 words
The method according to claim 1 , wherein the second video format is CIF.
Claim 9
Dependent Claim
20 words
The method according to claim 6 , further comprising frame grabbing an NTSC signal to produce the first data array.
Claim 10
Dependent Claim
14 words
The method according to claim 7 , further comprising packetizing the second data array.
Claim 11
Independent Claim
143 words
A system for transmitting a video signal of a first format via a communication protocol for a second format, said system comprising: a data processor to map data elements from a first data array representing a portion of a frame of the video signal of the first format into a second data array representing a portion of a frame of a video signal of the second format, wherein the number of rows and columns in the second data array is equal to or greater than the number of rows and columns in the first data array, said data processor also adapted to set to an arbitrary value each element in the second data array which does not correspond to an element in the first array; and a data transmitter to transmit the second array according to the communication protocol for the second format.
Claim 12
Independent Claim
143 words
A system for transmitting a video signal of a first format via a communication protocol for a second format, said system comprising: a data processor to map data elements from a first data array representing a portion of a frame of the video signal of the first format into a second data array representing a portion of a frame of a video signal of the second format, wherein the number of rows and columns in the second data array is equal to or greater than the number of rows and columns in the first data array, said data processor also adapted to set to an arbitrary value each element in the second data array which does not correspond to an element in the first array; and a data transmitter to transmit the second array according to the communication protocol for the second format.
Claim 13
Dependent Claim
18 words
The system according to claim 10 , further comprising a data receiver to receive the second data array.
Claim 14
Dependent Claim
23 words
The system according to claim 10 , further comprising a frame grabber to grab a frame of a signal in the first format.
Claim 15
Dependent Claim
17 words
The system according to claim 10 , further comprising a packetizer to packetize the second data array.
