Problems solved by technology

[0011] This is a problem because often multimedia captures may take place at different times, in different locations and thus under different environmental conditions; if these variations are not taken into account, the reproduction of the multimedia content may not be optimal and will not Appropriate to the environmental conditions that exist at the time of shooting

Embodiment Construction

[0025] The purpose of the present invention is to define a structure of dynamic metadata that improves the enjoyment of multimedia files, such as videos. This dynamic metadata can be updated during multimedia capture (audio, video, etc.) based on values ​​returned by sensors (GPS, accelerometer, orientation sensor, etc.).

[0026] In addition to performing the normal functions developed for them, the latest cellular phones and camcorders are also equipped with several sensors such as three-axis gyroscopes, accelerometers, proximity sensors, orientation sensors, ambient light sensors, GPS locators, and more. These sensors enrich the basic functionality of the device, which thus makes the device more useful for the user.

[0027] For example, a device equipped with such a sensor can provide information about the created multimedia file ( images, video, audio). Typically, these metadata are added to a dedicated storage area of ​​the multimedia file. In this way, for example, b...

Abstract

The process of capturing and / or reproducing multimedia content is described herein, the capture phase includes the steps of acquiring the multimedia content in the form of a substantially time-varying multimedia stream by means of a video capture device and possibly an audio capture device, by monitoring the capture parameter) acquires data related to the capture condition of the multimedia content, and stores the value of the capture parameter depending on substantially time-varying in the form of dynamic metadata for acquiring multimedia metadata in the associated captured multimedia content In the predetermined area of ​​the multimedia file; and / or in the reproduction stage, the following steps are included: reading at least the multimedia file comprising at least one multimedia content from the memory, reading at least one dynamic metadata of the multimedia content associated with the multimedia file form and data related to the capture conditions (capture parameters) of the volumetric content, and dynamically modify the reproduction mode of the multimedia stream corresponding to the multimedia file according to the value of at least the dynamic metadata associated with the multimedia content.

Description

technical field [0001] The present invention relates to a process and apparatus for recording and reproducing multimedia content by using dynamic metadata. Background technique [0002] Many portable devices have been around for many years and are used to record digital multimedia formats such as audio, video, and photos. In addition to these portable devices, a growing number of cellular telephones have appeared which, in addition to providing the typical functions of mobile telephones, allow recording of video clips or digital photography according to the latest digital compression standards. [0003] In addition to providing the typical capabilities of a cellular telephone, this device is also characterized by several features that enrich its functionality (eg GPS positioning system, accelerometer, orientation sensor, brightness sensor, etc.). [0004] These devices are currently capable of taking digital photographs, which are then stored and categorized into files; mor...
