SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, PROGRAM, AND SIGNAL TRANSMISSION SYSTEM

摘要

The present disclosure relates to a signal processing device, a signal processing method, a program, and a signal transmission system, which are capable of enabling video switching in frame units of an original video signal when a high-definition video signal having a high frame it is serially transmitted. A pixel thinning control unit thin out every other pair of two neighboring samples of each line from N consecutive frames of a video signal including an m×n(48P-60P)×N/r:g:b/10-bit or 12-bit signal in which the number of pixels per frame exceeds the number of pixels specified in an HD format at intervals of 2N lines, map the thinned every other pair of two neighboring pixel samples to first to 4N-th sub images including an m′×n′/48P-60P/r′:g′:b′/10-bit or 12-bit signal, and arrange a vertical blanking region between two of N regions in which pixel samples of respective frames of the first video signal are mapped in each sub image. For example, the present disclosure can be applied to a broadcasting camera.

主权项

1. A signal processing device, comprising:
a first pixel thinning control unit configured to thin out every other pair of two neighboring pixel samples of each line from N consecutive frames of a first video signal including an m×n (m indicating m samples and n indicating n lines are positive integers)/(48P-60P)×N (N is an integer of 2 or more)/r:g:b (r, g, and b are a signal ratio in the case of a predetermined signal transmission scheme)/10-bit or 12-bit signal in which the number of pixels per frame exceeds the number of pixels specified in an HD format at intervals of 2N lines, map the thinned every other pair of two neighboring pixel samples to first to 4N-th sub images including an m′×n′ (m′ indicating m′ samples and n′ indicating n′ lines are positive integers)/48P-60P/r′:g′:b′ (r′, g′, and b′ are a signal ratio in the case of a predetermined signal transmission schema)/10-bit or 12-bit signal, and arrange a vertical blanking region between two of N regions in which pixel samples of respective fumes of the first video signal are mapped in each sub image.
