Abstract

Dispositivo y sistema escalable que permite la alteración dinámica de flujos de vídeo minimizando su recodificación para la inserción de imágenes en fotogramas, tales como los logos identificativos de canales de televisión ("mosca"), sobreimpresión de múltiples canales (multi picture-in-picture), sobreimpresión de imágenes personalizadas, entre otras. Comprende un recortador (20), un sintetizador (30), un mezclador (40) y un controlador (10). El recortador (20) recorta regiones en los fotogramas de un flujo de vídeo (50) según un patrón de recorte (52) para producir un flujo recortado (60) y flujos de recortes (70) y/o escalados (74). El sintetizador (30) sintetiza flujos de vídeo coincidentes con los recortes según un patrón de síntesis (32) para producir flujos con recortes sintetizados (80) a partir de (70, 74). El mezclador (40) mezcla los flujos (60, 80) según un patrón de mezcla (42) para producir flujos de vídeo con recortes sobreimpresos (90). El controlador (10) coordina el funcionamiento conjunto.Device and scalable system that allows dynamic alteration of video streams minimizing their recoding for the insertion of images in frames, such as the logos identifying television channels ("fly"), multi-channel overprint (multi picture-in-picture) ), overprinting of custom images, among others. It comprises a trimmer (20), a synthesizer (30), a mixer (40) and a controller (10). The trimmer (20) cuts regions in the frames of a video stream (50) according to a crop pattern (52) to produce a clipped stream (60) and clip streams (70) and / or scaled (74). The synthesizer (30) synthesizes video streams matching the clippings according to a synthesis pattern (32) to produce streams with synthesized clippings (80) from (70, 74). The mixer (40) mixes the streams (60, 80) according to a mixing pattern (42) to produce video streams with overprinted clippings (90). The controller (10) coordinates the joint operation.
