First Claim
Patent Images
1. A method of optimizing bandwidth utilization in a broadcast system, comprising:
- determining that a broadcast signal will be displayed in at least two portions on a display apparatus;
treating a first of the at least two portions in a first manner;
treating a second of the at least two portions in a second manner that differs from the first manner; and
transmitting a combination of the first and second portions as part of a single broadcast signal.

Abstract
Methods and apparatuses for reducing network bandwidth utilization in TV broadcasting networks are provided. More specifically, the network bandwidth may be reduced by determining that an image will be displayed at smaller than full size on a display apparatus and in response to determining the image will be displayed at a smaller than usual size, reducing the resolution associated with the image. A reduction in the resolution associated with the image results in a reduction of the amount of network bandwidth required to transmit the image across the network.

16. A device for use in broadcasting television (TV) signals, comprising:
-
an input for receiving a datastream containing input image representative pixel data; a separation agent operable to determine that pixel data associated with a first portion of the datastream will be displayed on a first portion of a display apparatus and pixel data associated with a second portion of the datastream will be displayed on a second portion of the display apparatus, wherein the separation agent is further operable to separate the pixel data into the corresponding first and second portions; a processor for independently applying a first treatment algorithm to the first portion of pixel data and a second treatment algorithm to the second portion of pixel data thereby altering both the first and second portions of pixel data; and an output for transmitting a datastream containing output image representative pixel data, wherein pixel data associated with the output image comprises the altered first and second portions of pixel data. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A device for receiving broadcast television (TV) signals, comprising:
-
an input for receiving a datastream containing input image representative pixel data; a processor for independently applying a first treatment algorithm to a first portion of the datastream and a second treatment algorithm to a second portion of the datastream thereby altering the pixel data of each portion differently; and an output for transmitting the datastream comprising the first and second portions such that the pixel data associated with the first and second portions are simultaneously displayed. - View Dependent Claims (26, 27, 28, 29, 30)

31. A method of optimizing bandwidth utilization in a broadcast system, comprising:
-
dividing a full screen display into a number of portions; associating a fraction with each of the number of portions, wherein the fraction associated with a portion is based on the size of the portion compared to the full screen display; receiving a first datastream containing image representative pixel data; identifying the member of portions that will display the pixel data associated with the first datastream; and adjusting the pixel data of the first datastream based on the number of portions that will display the pixel data associated with the first datastream. - View Dependent Claims (32, 33, 34)

35. A method, comprising:
-
tuning to a single television channel that has been broadcast across a transmission network; determining that the channel contains two or more services; independently rendering each of the two or more services for display; and causing each of the two or more services to be displayed substantially simultaneously on a common display apparatus. - View Dependent Claims (36, 37, 38, 39, 40)
