[0049] A first embodiment of the present invention is described below. The video signal processing device practiced as the first embodiment is capable of converting acquired metadata having a representation format incompatible with the device into a representation format compatible therewith, and based on the converted metadata, performing a comparison with various Video signal associated processing. A video signal processing apparatus for realizing the above-mentioned features is described below.

[0050] 1. Video program production support system

[0051] First, the overall configuration of a video program production support system employing the video signal processing apparatus associated with the first embodiment will be described.

[0052] This video program production support system is installed in television stations and production companies for producing, for example, video content and movies, and supports the production of video programs, which are video works such ...

[0249] A second embodiment of the present invention is described below. The second invention is characterized in that the imaging device 40 converts the representation format of the metadata generated by the imaging device 40 into a representation format compatible with the editing terminal device 30, and correlates the converted metadata with the video signal, thereby correlating the associated metadata And the video signal is supplied to the editing terminal device 30, wherein the imaging device 40 is an example of a video signal recording device, and the editing terminal device 30 is an example of a video signal reproducing device. That is, considering the editing terminal device 30 using video signals and metadata, the imaging device 40 supplying these video signals and metadata converts the representation format of the metadata into a format that can be processed by the editing terminal device 30 before supplying the video signals and metadata. representation format.

[0277] A third embodiment of the present invention is described below. The third embodiment of the present invention is characterized in that the imaging device 40 as one embodiment of the video signal recording device correlates metadata generated by itself with a conversion table corresponding to the metadata and the video signal, and converts these metadata, conversion The table and the video signal are supplied to the editing terminal device 30 which is one embodiment of a video signal reproducing device. That is, considering the editing terminal device 30 using video signals and metadata, the imaging device 40 providing these video signals and metadata supplies the editing terminal device 30 with a conversion table corresponding to the metadata together with the metadata so that The editing terminal device 30 is allowed to easily convert this metadata for use.

Abstract

A video signal processor that can flexibly process metadata in a variety of representation formats. A video signal processor that processes a video signal. This video signal processor comprises a metadata representation format identification unit (432) that identifies the representation format of metadata described in predetermined language; a conversion table selection unit (434) that selects a conversion table, corresponding to the representation format of identified metadata, from one or more conversion tables prepared in advance; a metadata representation format conversion unit (436) that converts the representation format of metadata to a representation format processable by the video processor based on the selected conversion table; and a metadata application processor (480) that controls the processing for the video signal based on the metadata whose representation format has been converted. This configuration allows the video signal processor to flexibly process metadata in any format.

Description

technical field [0001] The present invention generally relates to a video signal processing device, a video signal recording device, a video signal reproducing device, a processing method thereof, and a recording medium. Background technique [0002] Recently, the use of metadata associated with captured video material (eg, video data) has become popular in the field of producing video productions such as television programs and video content. Effective use of this metadata requires metadata compatibility between the multiple equipment units used to produce the video production. For example, a case where metadata generated by a video signal recording device such as a video camera is used by a video signal reproducing device such as an editing device requires compatibility of metadata shared therebetween. [0003] However, traditionally, the representation and semantics of the aforementioned metadata lack completeness, so even in the same use of metadata, there is no compati...
