The invention relates to a portable storage medium, a media player, a method, and a signal for disturbing the perception of content provided in a first media stream. The first media stream is combined with a second media stream in at least one transport stream. The media player includes a control unit, which receives a user selection of reproducing content provided in the first media stream, (step 40), selects the second media stream for presentation together with the first media stream, (step 42), determines if there is a user- selectable object in the second stream having an action associated with it, (step 50), and at least orders the automatic performance of the action associated with the user-selectable object found, (step 52), in order to disturb the perception of content provided in the first media stream.

Various quality versions of an electronic content are defined, and one or more distortion algorithms (22, 32) that are executable to generate a lower quality version of the electronic content by a distortion of the highest quality version (21, 31) are defined. Each quality version is selectively assigned a content key (CK) whereby an electronic content player (34, 70) will have the appropriate information when decrypting, decoding, and/or distorting the highest quality version (21, 31) of the electronic content.

An apparatus for applying an anti-copy protection signal for use with switchable head recorders, such as Video Hi-FI recorders, is described. A high frequency pulsed signal is added to an original signal. The pulses interfere with the compensator circuitry such that the switching of the record head cannot adequately be masked on recording of a signal. On playback, the switching of the recording heads can subsequently be heard. In Video Hi-Fi recorders, the effect of the high frequency signals also interferes with the compressor-expander circuits to worsen the sound of the head switching.

A software agent (107) for digital rights management, comprising a unit (106) adapted to manage use rights for a given digital multimedia content (CONT) at a given portable electronic device (101), is characterized in that said software agent (107) is adapted to gradually degrade the quality of the digital multimedia content (CONT) upon reading or otherwise invoking the digital multimedia content (CONT). Also claims for a portable electronic device, a digital rights management system, and for a method for managing use rights for digital multimedia content.

A modified ColorstripeTM copy protection process utilizes a basic anti-copy protection (ACP) signal that causes attenuation of a video signal, wherein, in one embodiment, the process modifies (lowers) the level of a front porch portion and adds an incorrect color signal (color burst) in the region of the sync tip. When an illegal copy is made, a pre-blanked end of line portion causes a TV set to trigger the color burst sample pulse ahead of time and cause the incorrect color signal in the sync tip region to be sampled. Thus, since the sync tip region has incorrect color phase or frequency, the resulting illegal copy will have enhanced color distortions. In other embodiments, other portions of the horizontal blanking interval are lowered in level and incorrect color bursts are added to a portion or portions of the back porch and/or portion of the front porch. The various embodiments of the process may include an adaptable process, as well as several alternative ACP signals for use in combination with the process.

A recording of an information signal, which recording comprises the information signal and a spoiler signal, the spoiler signal being such that it is of a frequency which has been modulated to be in synchronism with a varying frequency modulating signal. Also provided are a method of recording an information signal in which the spoiler signal is also recorded, and apparatus for producing a recording of the information signal. The drawing shows a circuit diagram for the apparatus.

摘要:
The invention relates to a portable storage medium, a media player and a method of disturbing the perception of content provided in a first media stream. The first media stream is combined with other media streams to at least one transport stream and provided, together with at least one second media stream, on the portable storage medium. The media player includes a control unit, which retrieves a playing control unit from the storage medium and implements it, (step 37), receives a user selection of reproducing content provided in the first media stream, (step 40), selects the second media stream for presentation in relation to the first media stream based on the user selection, (step 44), and presents content provided in the second media stream in relation to the first media stream so that the content of the second media stream disturbs the perception of content provided in the first media stream, (step 48).
