Description

[Detailed description of the invention] Systems and devices for data transmission and related methods The invention relates to a system for transmitting data, and more particularly to a system for transmitting data to a remote location. Concerning transmission for display on.

Non-glare Ω and 1 Allows you to send data, collect responses to this data, and analyze these responses. Systems for storing data in a format that is of interest to the art for many years. . Such systems include, for example, polling and rate can be used for rating services.

Many other uses, such as access to central database information systems, are available to those skilled in the art. It is obvious that

In the consumer sector, such polling can be done by e.g. , used to determine consumer preferences for television programs or channels. Ru.

Research services traditionally use multiple different methods to collect their responses. I've been using it. One of these methods is to ask a question in the form of a letter requesting a response. There is a way to send a letter. This means writing an address on a letter, sending it, receiving it, and writing it. responses are then manually analyzed or compiled by a research firm. The data must be entered into a computer, which is very costly and time consuming. Ru. Furthermore.

Response yield is low due to the significant amount of time required to write the response by the consumer. poor and inaccurate. *Another method of conducting an inspection is verbally over the telephone. This is the way to do it. Making phone calls and listening to people's questions is expensive, and the company is Requires manual calculation or entry of responses.

Another traditional data collection method is to give survey participants diaries. . Participants may keep records of the programs they watch or the products they use. Must be entered in the diary. These diaries are then collected and responses are handwritten. Analyzed at work or entered into a computer. This applies to both participants and companies. This is a very labor-intensive task.

Entering the electronic age, an attempt to simplify the process for both the company and the participants Now I can see it.

Barcode readers allow researchers to track products encoded with universal product codes. make it possible to do Response data read by these readers is stored in a database, which shows the products of interest covered by that survey. sold to a company with In practice, this system is usually non-discriminatory. For example, if a barcode reader is installed at a Korean grocery store, All products that come out are entered into the database. This represents a significant amount of useful data. data, but in addition, it can also store a significant amount of unusable data. It becomes. In other words, the database becomes too large to use; The cost is high and it is also complicated.

Some systems for determining television ratings are fully automated. C Hardware devices can be hooked directly to monitor TV channel usage. , this information is transmitted to a central computer using a dedicated telephone line. This Although the system is fully automated, the hardware implementation costs are considerable. This only gives specific information about the time, duration and channel watched. Ru.

Systems that provide moment-to-moment viewer responses to an event are particularly effective. 8 Well-known systems in which the event is such that individual participants respond differently, e.g. A design to allow him/her to enter his/her response by means of the corresponding button. The response data must be carried out in a room equipped with collected over a single day, combined with known demographics of the audience, and synchronized with the event. expected. Clearly, this system does not require participants to go out to a central location. and request. Therefore, the event may occur in a setting that is unfamiliar to the participants. This may change the reliability of his or her response.

*Up until now, it has been very difficult to conduct instantaneous audience research online by telephone. For example, creating a dedicated A telephone line was required.

In the area of information systems, applications of the invention include personal combinators and This includes access to a central database using a computer and modem. system operation The controller creates and maintains a database within the host computer and typically has permissions Access is controlled via passwords issued to authorized users. hostco The user's request and the host's answer are sent to the computer via the telephone network. sent and received. Users are required to pay for subscription and/or connection time. Fees will be charged on a base basis. This allows access to infinite amounts of data . However, this system allows each user to use a personal computer and computer. requires investing in the necessary software and modem to operate the computer.

Additionally, users are responsible for determining how to make calls, sign their arrival, and request requests. You must search for information or receive education.

This system is useful for more advanced computers with specialized and non-standard information needs. Appropriate for users.

Furthermore, for the mass distribution of information, personal computer information systems are Requires individual users to access a central database using a telephone line do. This ties up the user's phone and phone system, and the host computer Requires having a large number of access ports.

In order to simplify this personal computer system, it is possible to make it more user-friendly and professional. An information access system has been developed for The user enters a key to complete the search. - Just enter the numerical response on the pad.

These systems typically have graphics-based screens, with individual requires a fairly long drawing session. Also, for this system Purpose-built receivers and decoders are too expensive to appeal to the mass market. Giru. A system that allows all users to access the host is Bind the line and host computer access boat.

Another information system transfers that information to the vertical blanking period of regular television signals. Send within the normally unused part between. Visual MW needs to be specialized to view this information. Systems using this vertical blanking period must have a decoder for A major limitation of systems is limited bandwidth.3 Typically, pages run in loops. , and you want the access time to be reasonable, only a limited number of pages can be accessed. unable to send, Other systems include cable TV services available in most cities throughout North America. use the Unfortunately, not all homes are equipped with basic cable service. However, very few households have two-way cable systems and therefore Interactive uses are excluded.
