64results about How to "High-quality reproduction" patented technology

Portable appliance, power saving method and sound volume compensating method, and storage medium

There are provided a mobile device that is equipped with a musical composition-reproducing section and capable of curtailing the battery drain as much as possible, and a mobile device that prevents the quality of reproduced musical tones from being degraded even if the voltage level of the battery lowers. A battery voltage detector monitors an voltage level of a battery. The musical composition-reproducing section is controlled such that the number of parts of the musical composition reproduced by the musical composition-reproducing section is reduced when the monitored voltage level of the battery becomes lower than a reference value. In other forms of the invention, when the monitored voltage level of the battery becomes lower than a reference value, a first predetermined number of parts of the musical composition data are assigned to intrinsic ones of a larger second predetermined number of parts that correspond to the first predetermined number of parts of said musical composition, as well as to other ones of the second predetermined number of parts than the intrinsic ones, for reproduction of the musical composition, or the gain of a variable-gain amplifier is increased to compensate for the lowering of the volume of the reproduced parts.

Audio/video reproducing apparatus and method

An audio / video reproducing apparatus is connectable to a communications network for selectively reproducing items of audio / video material from a recording medium in response to a request received via the communications network. The audio / video reproducing apparatus may comprise a control processor operable in use to receive data representing the request for the audio / video material item via the communications network. A reproducing processor is operable in response to signals identifying the audio / video material items from the control processor to reproduce the audio / video material items. The data identifying the audio / video material items includes meta data indicative of the audio / video material items. The meta data may be one of UMID, tape ID and time codes, and a Unique Material Identifier the material items. To facilitate the identification and selection of the audio and / or video material, an audio and / or video processing apparatus is provided for processing audio and / or video signals representing sound and / or images. The processing apparatus comprises an activity detector operable to generate an activity signal indicative of an amount of activity within the sound / images represented by the audio / video signal, and a meta data generator coupled to the activity detector which is operable to generate sample images at temporal positions within the audio / video signal, which temporal positions are determined from the activity signal. The processing apparatus thereby provides a facility for automatically generating meta data from received audio / video signals. The meta data can be used to select the audio / video material.
