To facilitate the distribution of video contents, MPEG-DASH (Dynamic Streaming over HTTP) standard is developed to provide standardized manifest format, content format and streaming protocol for adaptive streaming, thereby increasing interoperability of Internet TV services. Although DASH contents are delivered by HTTP without supporting data multicast, some studies shows the possibility of delivering...
In recent years, application-layer forward error correction (AL-FEC), particularly rateless AL-FEC, has received much attention due to its superior performance in both transmissional and computational efficiency. Rateless AL-FEC (e.g., Raptor code or Luby transform (LT) code) can protect a large data block with an overhead somewhat close to ideal codes. In the meantime, its data processing rates of...
Several studies indicate that video contents will be the vast majority of Internet traffic in the near future. To facilitate the distribution of video contents, we have to overcome the issue of interoperability between various servers and devices. MPEG-DASH standard is developed to provide standardized manifest format, content format and streaming protocol for adaptive streaming, thereby increasing...
In this paper, we implement our previously proposed inter-layer protection scheme to protect the RTP-based SVC video streaming service based on the DVB AL-FEC. The proposed scheme enables the video data in a more important layer to be recovered with a higher probability. To verify the feasibility of the proposed scheme, we fully design and implement the corresponding interfaces and components. The...
Scalable Video Coding (SVC) enables the partition of video data into layers of different priorities for adapting to both the diversities of terminal capabilities and the variation of network transmission mediums. It is more desirable that more important video data can be recovered with higher probabilities. In this paper, we propose a lightweight inter-layer protection scheme for SVC transmission,...
FLUTE is a file delivery protocol whose operation can only require a unidirectional communication channel from a sender to a receiver. Due to the nature of unidirectional delivery, FLUTE is designed in a flexible way so that it can cooperate with different kinds of forward error correction codes in application layer, such as systematic Raptor codes or other FEC codes defined in IETF. Besides, since...
Several applications benefited from multicast data distribution because a sender can concurrently transmit data to multiple receivers using fewer bandwidth. However, reliability is an important issue in multicast because retransmission is not very efficient in multicast. In recent years, Forward Error Correction (FEC) codes are proposed to facilitate reliable multicast data distribution and are applied...
Forward error correction (FEC) allows the receiver to correct erasure without asking retransmission. This advantage is significant for several applications where retransmission is not available or desirable. In recent years, applying FEC codes to peer-to-peer data distribution networks is an innovation. In this way, the downloader can efficiently reconstruct the data from the encoding symbols multicasted...
Multicast transmission enables a sender to distribute data to multiple intended receivers simultaneously. However, the multicast transmission should be reliable in erasure channel. Forward Error Correction (FEC) enables the lost packets to be recovered from some extra redundant packets without any retransmission. In this paper, we propose a new FEC codes, called Polynomial Interpolation codes (PI...
