“…DVB-H (Digital Video Broadcasting -Handheld), the specification for bringing broadcast services to battery-powered Mobile Handsets (MHs), was formally adopted as an ETSI standard in November 2004 [1]. However, due to the wireless channel characteristic and wireless broadcast properties, MHs are vulnerable to lose packets in a wireless environment [2,3]. Some studies are trying to deal with the DVB-H data loss problem, [4] adopts a cellular network to transmit repair data, [5] proposes an FEC scheme to deliver DVB-H lost packets to improve transmission efficiency, and [6] integrates DVB-H with a 3G network to transmit data for the recovery purpose.…”

DVB-H is developed to broadcast digital videos to mobile handsets, but data loss is a concern due to the wireless broadcasting nature. In this paper, take WiMAX as an IPbased wireless network to recover the loss packets in DVB-H, and take E-WP based on network coding as the encoding packet selection algorithm. Furthermore, a prioritized scheme EWP-PNC based on E-WP packet selection algorithm is proposed. In this scheme, take a base station in WiMAX as encoding node to encode any two packets that meet the encoding and decoding necessary and sufficient condition into an encoding recovery packet according to the current lost packet distribution, and calculate the benefit of each encoding packet to decide the final priority of all encoding packets. The goals of this scheme are to improve the lost packet recovery ratio and reduce the discarded packet ratio. According to the simulation results, the validity of this scheme is proved.

SUMMARYThe digital video broadcasting-handheld (DVB-H) standard is developed by European Telecommunications Standards Institute to broadcast digital videos to handheld devices, but data loss is a critical issue due to the broadcast behavior. On the other hand, DVB-Internet protocol datacasting (DVB-IPDC) integrates DVB-H with an Internet protocol-based wireless network to provide bidirectional communication. We adopt this wireless network to deal with data retransmission and call it a recovery network. The paper argues that network coding can improve retransmission efficiency of the recovery network because DVB-H packet loss often exhibits high correlation. In addition, DVB-H packets may be heterogeneous in the sense that they have different importance. According to these two arguments, the paper considers that DVB-H packets are associated with different profit depending on their importance and proposes an˛-maximum profit network coding problem. It asks the base station in the recovery network to use no more than˛coded packets for handheld devices to retrieve the lost DVB-H packets such that the overall profit is the maximum. An efficient exclusive-or coding scheme, namely the profit-based exclusive-or network coding (PEN) algorithm, is proposed to solve this problem. Extensive simulation results also verify the effectiveness of the PEN algorithm.

Recently, digital video broadcasting‐handheld (DVB‐H) and IP datacast over DVB‐H (DVB‐IPDC) have been developed to support broadcasting services. DVB‐H is designed to support digital video broadcast for handheld devices, whereas DVB‐IPDC can integrate with an IP‐relay network to complement the data loss problem in DVB‐H. Assuming that WiMAX networks are adopted to support DVB‐IPDC, this paper points out two critical problems: group packet loss (GPL) and broadcast data handover (BDH). GPL occurs when there is a burst of retransmission requests for the same pieces of data with high spatial or temporal correlation. BDH happens when some devices that made the above requests handover to new serving cells. To solve these problems, we propose lazy wait and group acknowledgement schemes to alleviate duplicate requests by exploiting their spatial and temporal correlations. This not only reduces the requests submitted by neighboring devices in both space and time domains but also avoids handovering devices from sending duplicate requests in new cells. Through mathematical analysis, we show how to adaptively adjust the timers of lazy wait and group acknowledgement based on channel quality. Simulation results prove that our schemes can efficiently reduce retransmission requests and retransmission packets, thus alleviating congestion in the IP‐relay network.
