    摘要: 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.

    摘要: An audio and/or video generation apparatus comprises a recording processor which is operable to record audio and/or video signals on a recording medium, a meta data generation processor which is operable to generate meta data identifying the content of the audio/video signals, and a communications processor which arranged to communicate the meta data separately from the recording medium.Furthermore, the meta data generation processor may be operable to generate at least one sample image which is representative of a video image from the recorded video signals, and to associate the sample image with an address on the recording medium at which the video image is recorded. The video and/or audio generation apparatus provides an advantage in generating and utilising meta data to facilitate the generation of audio/video productions. Accordingly, a system for generating an audio and/or video production comprises an acquisition processor operable in use to receive instructions from a user which instructions are representative of a list of content items for the audio and/or video production. The audio and/or video generation apparatus is arranged in use to receive information representative of the list of content items, and to generate audio and/or video signals in accordance with the content items on the list. An ingestion processor may be provided to receive the list of content items, and the audio and/or video signals and to form the audio and/or video production by associating the audio and/or video signals with the list of content items.

    摘要: Method and apparatus for digital calibration of an analog-to-digital converter (ADC). One example relates to calibrating an analog-to-digital (A/D) conversion system having an N-bit resolution. The A/D conversion system includes an ADC that generates an output having N most significant bits (MSBs) and M least significant bits (LSBs) (i.e., an N+M bit resolution). An offset calibration circuit is configured to determine an offset in the ADC and to compensate the N+M bit output using the offset to provide an N+M bit offset corrected output. A gain calibration circuit is configured to determine a gain correction factor for the ADC and to compensate the N+M bit offset corrected output using the gain correction factor to provide an N bit offset and gain corrected output.
