ABSTRACT:
TECHNICAL FIELD
The invention relates to television entertainment systems for providing television programming to consumer homes. More particularly, the invention relates to a network controller that monitors, controls and manages a television program delivery network from a cable headend.
BACKGROUND OF THE INVENTION
Advances in television entertainment have been primarily driven by breakthroughs in technology. In 1939, advances on Vladmir Zworykin's picture tube provided the stimulus for NBC to begin its first regular broadcasts. In 1975, advances in satellite technology provided consumers with increased programming to homes.
Many of these technology breakthroughs have produced inconvenient systems for consumers. One example is the ubiquitous three remote control home, having a separate and unique remote control for the TV, cable box and VCR. More recently, technology has provided cable users in certain parts of the country with 100 channels of programming. This increased program capacity is beyond the ability of many consumers to use effectively. No method of managing the program choices has been provided to consumers.
Consumers are demanding that future advances in television entertainment, particularly programs and program choices, be presented to the consumer in a user friendly manner. Consumer preferences, instead of technological breakthroughs, will drive the television entertainment market for at least the next 20 years. As computer vendors have experienced a switch from marketing new technology in computer hardware to marketing better useability, interfaces and service, the television entertainment industry will also experience a switch from new technology driving the market to consumer useability driving the market.
Consumers want products incorporating new technology that are useful, and will no longer purchase new technology for the sake of novelty or status. Technological advances in sophisticated hardware are beginning to surpass the capability of the average consumer to use the new technology. Careful engineering must be done to make entertainment products incorporating new technology useful and desired by consumers.
In order for new television entertainment products to be successful, the products must satisfy consumer demands. TV consumers wish to go from limited viewing choices to a variety of choices, from no control of programming to complete control. Consumers wish to advance from cumbersome and inconvenient television to easy and convenient television and keep costs down. Consumers do not wish to pay for one hundred channels when due to lack of programming information, they seldom, if ever, watch programming on many of these channels. Viewers wish their programming to be customized and targeted to their needs and tastes.
The concepts of interactive television, high definition television and 300 channel cable systems in consumer homes will not sell if they are not packaged, delivered and presented in a useable fashion to consumers. Consumers are already being bombarded with programming options, numerous “free” cable channels, subscription cable channels and pay-per-view choices. Any further increase in TV entertainment choices, without a user friendly presentation and approach, will likely bewilder viewers with a mind-numbing array of choices.
The TV industry has traditionally marketed and sold its programs to consumers in bulk, such as continuous feed broadcast and long-term subscriptions to movie channels. The TV industry is unable to sell its programming in large quantities on a unit per unit basis, such as the ordering of one program. Consumers prefer a unit sales approach because it keeps costs down and allows the consumer to be more selective in their viewing.
In today's television world, networks manage the program lineup for individual channels. Each network analyzes ratings for television shows and determines the appropriate schedule or program lineup to gain market share and revenue from advertising. Program ratings are determined using a test group of viewers and statistical analysis methods. Since each channel is in competition with every other channel, there is no coordinated effort to organize television programming in a manner that primarily suits the viewers.
Advertising has become equally annoying, with viewers being “forced” to watch television commercials for goods and services that are neither needed nor desired. As a result, consumers have become impatient and dissatisfied with today's television delivery systems. Equally problematic, these television delivery systems do not have the capabilities or features necessary to operate in the digital environment. Consequently, advances in digital technology call for a new television program delivery system that is capable of satisfying varying consumer and viewer needs.
Existing cable headends are unequipped for the transition to a digital system. These cable headends have no means for monitoring and controlling the large numbers of program signals and advertisements that will eventually be passed on to both consumers and viewers. These cable headends are unequipped to manage account and billing information for set top terminals without relying on telephone lines. In addition, these cable headends have no means for targeting advertisements to particular consumers and viewers.
What is needed is a network controller for a digital cable headend used in a television delivery system.
What is needed is a versatile network controller for a cable headend.
What is needed is a network controller for use in a cable headend that Is capable of operating in both the digital and analog environment.
What is needed is certain components of a network controller for a digital cable headend used in a cable television delivery system.
What is needed is a network controller capable of controlling multiple video/audio program signals received by a cable headend from a satellite transponder.
What is needed is a network controller that can control the routing of both analog and digital video/audio program signals from cable headend to viewer homes.
What is needed is a network controller component for a cable headend that controls the combining the digital video/audio signals.
What is needed is a network controller that creates tiered programming by combining various digital video/audio signals.
What is needed is a network controller for a cable headend that accommodates different bandwidth availability between cable headend and certain viewer homes.
What is needed is a network controller capable of modifying program control information received from an external source.
What is needed is a network controller capable of targeting video to viewers.
What is needed is a network controller capable of targeting television commercials to specific consumers and viewers.
What is needed is a network controller capable of gathering information on programs watched by viewers.
What is needed is a better method of determining program ratings.
What is needed is a network controller capable of managing account and billing information.
The present invention is addressed to fulfill these needs.
SUMMARY OF INVENTION
The present invention is a network controller for a television delivery system. The network controller is the central component that provides monitoring and control of set top terminals in a television delivery system. The network controller is a key component of a digital cable television delivery system. The network controller of the present invention provides much greater capability and flexibility than existing cable headend control equipment.
The network controller of the preferred embodiment performs all its cable network monitoring and control of set top terminals within the cable headend. The cable headend receives and processes digitally compressed program signals before the signals are relayed to each set top terminal. Each cable headend site is equipped with multiple satellite receiver dishes and a signal processor.
As an intermediary between the set top terminals and the program delivery system&apo
