Abstract
(EN)
A competition video subtitle processing method and a broadcast guiding system, the method comprising: obtaining competition data during a competition process, the competition data comprising data sent by external equipment; rendering the competition data in a first preset subtitle template of a display area of a preset application to generate a fill signal image, the display area also comprising a second preset subtitle template, and the second preset subtitle template being a key signal image corresponding to the fill signal image; and transmitting the fill signal image to a broadcast guiding station, and transmitting the key signal image to the broadcast guiding station, so that the broadcast guiding station can synthesize a video stream to be displayed according to the fill signal image and the key signal image to obtain a new video stream. By means of using a preset application on a computer to implement a fill signal image and a key signal image, online loading of competition data during the competition process can be achieved, without requiring the purchase of a special subtitle machine, thus reducing the hardware costs.

Procédé de traitement de sous-titres de vidéo de compétition et système de guidage de diffusion, le procédé consistant à : obtenir des données de compétition pendant un processus de compétition, les données de compétition comprenant des données envoyées par un équipement externe ; rendre les données de compétition dans un premier modèle de sous-titres prédéfini d'une zone d'affichage d'une application prédéfinie pour générer une image de signal de remplissage, la zone d'affichage comprenant également un second modèle de sous-titres prédéfini, et le second modèle de sous-titres prédéfini étant une image de signal clé correspondant à l'image de signal de remplissage ; et transmettre l'image de signal de remplissage à une station de guidage de diffusion, et transmettre l'image de signal clé à la station de guidage de diffusion, de sorte que la station de guidage de diffusion puisse synthétiser un flux vidéo à afficher en fonction de l'image de signal de remplissage et de l'image de signal clé pour obtenir un nouveau flux vidéo. L'utilisation d'une application prédéfinie sur un ordinateur pour implémenter une image de signal de remplissage et une image de signal clé, permet le chargement en ligne de données de compétition pendant le processus de compétition, sans qu'il soit nécessaire d'acheter une machine à sous-titres spéciale, ce qui réduit ainsi les coûts de matériel.
