发明名称 Time shift and tonal adjustment to support video quality adaptation and lost frames
摘要 A digital electronic device includes a time shifter/tone adapter that eliminates unwanted audio effects at recipient device, that includes stutter and loss of audio synchronization, as a result of video quality adaptation (the video quality adapter varies frame rate, pixel and color resolutions without having a discernable difference in picture quality, that is, drops many frames in every frame set). The tone adaptation involves gradual frequency shifting, that is, gradual up shifting until synchronization with video is obtained (time shifting), then gradual down shifting. The recipient device (or a set top box) may contain a time shifter/tone adapter that eliminates unwanted audio effects at the recipient devices that may include stutter and loss of audio synchronization, as a result of loss of packets in channel.
