A configuration capable of recording MMT format data on a medium as BDAV format data and performing copy control according to the original copy control information is achieved. The MMT format data, for which copy control information is set, is input and recorded on an information recording medium as BDAV format data. As record data, (a) a stream file including a packet string in which the MMT format data is stored, and (b) copy control information corresponding to the stream file, in which the copy control information corresponding to the MMT format data is reflected, are generated and recorded as an additional header of a packet included in the stream file or as another file.

An editing method includes: obtaining a high quality image and a first low quality image that are still images showing an identical scene, and edit management information that indicates whether or not to permit editing at least one image of the high quality image and the first low quality image; and editing the at least one image when the edit management information indicates to permit editing the at least one image, and when the edit management information indicates not to permit editing the at least one image, the at least one image is not edited.

A method of modifying the output of an output device is provided. A first code, associated with a first recipient party, is received and used to generate, within the output device, a second code, the second code containing encoded data identifying the first recipient party and instructions for activating an additional functionality of the output device. The additional functionality is activated in accordance with the instructions contained in the second code. The output of the output device is modified according to data encoded in the second code, to encode a third code in the output of the output device, the third code including an ID code associated with the first recipient party.

An adaptive interface for a programmable system, for predicting a desired user function, based on user history, as well as machine internal status and context. The apparatus receives an input from the user and other data. A predicted input is presented for confirmation by the user, and the predictive mechanism is updated based on this feedback. Also provided is a pattern recognition system for a multimedia device, wherein a user input is matched to a video stream on a conceptual basis, allowing inexact programming of a multimedia device. The system analyzes a data stream for correspondence with a data pattern for processing and storage. The data stream is subjected to adaptive pattern recognition to extract features of interest to provide a highly compressed representation that may be efficiently processed to determine correspondence. Applications of the interface and system include a video cassette recorder (VCR), medical device, vehicle control system, audio device, environmental control system, securities trading terminal, and smart house. The system optionally includes an actuator for effecting the environment of operation, allowing closed-loop feedback operation and automated learning.

In aspects of recorded content managed for restricted screen recording, a wireless device displays digital image content, and a screen recording session captures the digital image content and audio data. The wireless device implements a content control module that determines a device application restricts the screen recording session from capturing the media content. The content control module can then pause the screen recording session for a time duration that the device application restricts the screen recording session, and then resume the screen recording session after a determination that the screen recording session is no longer being restricted. As an alternative to pausing the screen recording session, the content control module can add a start delimiter to indicate a beginning section of the screen recording session being restricted by the device application, and add an end delimiter to indicate an end section of the screen recording session being restricted.

In some embodiments, a method includes receiving, at a device, digital audio content to be converted by a digital-to-analog converter to produce analog audio content. The digital audio content has at least one audible frequency. The method also includes selecting, at the device, a first signal and a second signal to output with the analog audio content. The first signal has an inaudible carrier frequency and a bandwidth, and the second signal also has an inaudible carrier frequency and a bandwidth. A difference between the first signal and the second signal is an undesired audible signal. The method further includes outputting, from the device, the analog audio content, the first signal and the second signal, such that when the analog audio content is detected by a recording device the undesired audible signal is detected with the analog audio content.
