Аннотация:This work includes three parts: (1) underwater channel study to determine necessary power levels and frequency allocation, (2) video compression to reduce the amount of data to be transmitted through the channel, and (3) OFDM modulation to achieve high bit rates over the underwater link. The feasibility of underwater wireless video transmission using an acoustic multicarrier system for applications such as deep-sea supervisory control and inspection is discussed and proved. The results demonstrate the usefulness of the coupled MPEG-4 compression and OFDM modulation, reaching bit rates on the order of 90 kbps in a 115 kHz acoustic band over a 200-meter link under a variety of channel conditions. Such a system is of interest over short distance links, with short delays and high available bandwidth, as near real time imagery can be transmitted to monitor targeted underwater spots. Experimental testing was conducted at the MIT Sailing Pavilion premises, in the Charles River, Boston.

Создание VideoCD

Для сжатия видео до такой скорости использовали алгоритм сжатия MPEG1 - видеопоток со скоростью 1125 kbi /s, аудиопоток со скоростью 224 kbi /s, что позволяло записать более 70 минут видео с качеством, как утверждали VHS. Таким оно и было, если в видеоматериале не было быстрых движений на экране, в противном же случае экран покрывался десятками и сотнями квадратиков. Стандарт Video CD 2.0, принятый годом позже, добавил возможность создания экранного меню и неподвижных изображений. Video CD могут воспроизводиться на компьютере программными или аппаратными проигрывателями, CD-I-плейерами (So y PlayS a- io ), VideoCD- и DVD-проигрывателями. Video CD 1.0 представляет собой один и более треков аудио/видеоданных в формате MPEG1 (аналогично аудиодиску). Процесс воспроизведения его также аналогичен CD: после воспроизведения первого трека начинает воспроизводиться второй и так далее. При записи фильмов обычно делают два трека: первый - с заставкой производителя, второй - собственно фильм, при этом всегда есть возможность эту заставку пропустить.
