Media-aware scheduling method for transmitting signalling message over MPEG media transport-based broadcast

The broadcasting system should send signalling messages frequently because users randomly access to the broadcast service. However, the repetition of transmitting these data wastes network resources such as the limited bandwidth. To solve this problem, we propose a media-aware scheduling method of signalling messages for MPEG media transport (MMT)-based broadcasting. MMT recommends that the sending entity may send signalling messages at regular time intervals, but our method considers the media type when sending messages. We compared and analysed between two methods with various media encoding parameters which impact on overhead size. As a result, the proposed method not only maintained the latency time as similar as the MMT's proposal but also reduced overhead size.
