Collection of usage data
SUBSTANCE: invention is related to methods of usage data collection for television broadcast receivers. Method of usage data collection from broadcast receiver is suggested, whereat receiver is arranged to detect and save such usage data. Method involves representation (16, 18) of confidentiality policy to receiver that identifies not only the usage data subjected to collection, but also preset usage of such data. On receiver interactive or automatic determination (22) whether received policy of confidentiality is acceptable is carried out. If yes, receiver picks up (30) usage data identified in confidentiality policy from storage, and sends them (28) to sender of confidentiality policy.

The technical field to which the invention relates
The present invention relates to a method of collecting data relating to the selection performed by the user and the device that supports the mentioned data collection. In particular, although not exclusively, the invention relates to the collection of data for use with receivers for television broadcast.
Digital set-top box (or any other TV broadcast receiver) has the ability to record actions of the user, for example, which channels he was watching and when he looks. When this television set is connected to the back channel, this information can be transmitted from set-top boxes the other side.
This information is useful for companies, for example, broadcasters, to analyze the demographics of view and to inform consumers on the offers and services that may be of interest to them. However, for the consumer, there are privacy issues of using information about their viewing habits, and this can lead to reluctance on the part of users to access their information.
The present invention is at least a partial solution to the above problem.
According to the first aspect of the present invention, nedosmotrel method of data collection use with a broadcast receiver, made with the possibility of discovery and preservation of such data spaces containing phases in which
In addition, according to the present invention, a device for data collection use, containing
the broadcast receiver (which may be a receiver of TV broadcasting);

These and other aspects of the present invention set forth in appended claims included in this application by reference and to which the reader is now sent, and/or are described in the following description of embodiments of the invention.
List of figures
Embodiments of the present invention will be described by way of example only with reference to the accompanying drawings, in which
Fig. 1 is a diagram of a sequence of interactions between the broadcaster and the receiver according to the present invention;
Fig. 2 is a logical block diagram of the alternative steps that can be performed on the receiver side, of figure 1; and
Fig. 3 is a schematic representation of the functional characteristics of the device conforming to the present invention.
Detailed description of the invention
In this description, the term "broadcaster" will be used, in General, to specify a company or other organization that wants to get the profile information of the viewer. There can be many different the types of companies who may wish to obtain profile information, but the broadcaster is probably the first user, and the use of the term "broadcaster" helps to clarify the following.
In Fig. 1 illustrates the sequence of interactions between the broadcaster (on the left in the figure) and receiver (right). First, the broadcaster transmits 10 one or multiple data streams for broadcast. On the receiver selects 12, usually in accordance with user input which thread (for example, what TV channel to watch or record. On the receiver are registered 14 such election in the non-volatile storage for constructing a picture of the viewing habits of the user, which information is of interest to the broadcaster to provide improved schedules, special offers, etc.
Although a detailed review of the above example is not required, we turn our attention to some part of the purpose of illustration only.
These references indicate the desired data, such as name and gender of the user, the time and date of viewing a recorded audio/video (AV) content (information meaningful content or viewing or recording AV-real-time content.
The one who receives the data.
How long the recipient will hold the data (endlessly in the above example).
Specifies the intended use of the data (in this example, create a demographic profile).
After you create a policy file needs to be transferred 18 on the digital set-top box consumer. Specific details of this transfer are not included in the scope of the invention, but the person skilled in the art known in the art suitable mechanisms for moving data together with the data broadcasting or separately) to the receiver.
When the background of the viewer 28 is transferred from the consumer to the broadcaster, the policy file is used to filter 30 background view. For example, if you had a policy file that specifies only the information about which programs are viewed, all other information in registriernummer will be removed prior to transfer.
If the purpose of the background view is creating an anonymous profile (target specified in the policy file), digital set-top box can replace 32 with any information that identifies the user (e.g., name, user ID, etc) aliases to ensure that the broadcaster will not be able to use the history view for direct analysis of the viewer.
After having read this disclosure, the experts in this field can offer other modifications. Such modifications may involve other features which are already known in the field of data collection, methods and devices that support it, and that you can use instead of the already described here signs or work together with them.
