Abstract

a presente descrição descreve um método, um aparelho e um meio legível por computador para controle de congestionamento em comunicações sem fio. por exemplo, o método exemplar pode incluir a determinação de uma pluralidade de deltas de transmissão de imagem, em que um delta de transmissão de imagem é uma diferença entre tempos de transmissão de duas imagens consecutivas. o método exemplar inclui ainda determinar se o congestionamento associado ao recebimento de pacotes de protocolo de transporte em tempo real (rtp) está presente com base em um jitter de delta de transmissão de imagem, determinar uma nova taxa de bits máxima com base em uma taxa de bits máxima atual e uma determinação que congestionamento está presente, e transmitir a nova taxa de bits máxima para um dispositivo de envio.
