Tóm tắt

Bài báo này trình bày kết quả thử nghiệm ứng dụng công nghệ 5G cho sản xuất video từ xa (SXTX) được thực hiện tại Đài Truyền hình Việt nam (VTV). Mô hình thử nghiệm sử dụng camera truyền video qua mạng 5G để sản xuất chương trình thể thao trực tiếp tại SEA Games 31 cho môn thi đấu Golf. Một số kết quả đo kiểm chất lượng video và thông số mạng 5G cho SXTX được trình bày. Kết quả thử nghiệm chương trình thể thao với 4 camera kết nối bộ 5G cho sản xuất video trực tiếp. Sử dụng 2 SIM/1 Modul 5G kèm theo camera để capture tín hiệu video. Ở phía thu (Phòng điều hành sân Golf Đầm Vạc, Vĩnh Phúc) dùng 1 bộ decoder giải mã tín hiệu ra luồng SDI đưa đến video switcher, CG, bộ làm chậm,…Kết hợp với hệ thống âm thanh để bình luận. Tín hiệu đồng bộ thực hiện qua bộ Decoder. Video thử nghiệm với codec H.265, tốc độ bit Uplink/1 camera là 15.6 Mbps, với độ trễ 700ms (encoder-decoder). Một số kết quả đạt được ban đầu minh chứng cho khả năng sử dụng 5G cho SXTX một số môn thể thao tại VTV. Ngoài ra, kết quả thử nghiệm cũng giúp các nhân viên kỹ thuật sản xuất chương trình kiểm tra và đánh giá các thông số thiết lập video/audio nhằm đảm bảo các yêu cầu tối thiểu về chất lượng cho sản xuất và phân phối chương trình HD sử dụng HEVC codec đường uplink qua mạng 5G.
