With the convergence of telecommunication infrastructures, computer technology, and media content services, mobile TV offerings have become feasible. Mobile TV offerings are defined as real-time broadcast transmissions of content to mobile devices. Research on early adopters suggests that 3Italia's Mobile TV offerings, the world's first nationwide DVB-H Mobile TV offerings, are experiencing increasing use, user preferences for time sensitive content, and user satisfaction with content. Our analysis suggests that from a user perspective, Mobile TV offerings represent a convergence of familiar technologies. The familiar nature of offerings may lead to emergence of fewer technology induced paradoxes than what has been found with other mobile services. We find that only two paradoxes appear relevant to Mobile TV use: empowerment / enslavement and engagement / disengagement. Future research must wait for a richer set of paradoxes emerging from a stronger consideration of broadcast technology and services. This paper contributes to innovation research on mobile services.

Forward Error Correction (FEC) is commonly used for content broadcasting. The performance of the FEC codes largely vary, depending in particular on the code used and on the object size, and these parameters have already been studied in detail by the community. However the FEC performances are also largely dependent on the packet scheduling used during transmission and on the loss pattern introduced by the channel. Little attention has been devoted to these aspects so far. Therefore the present paper analyzes their impacts on the three FEC codes: LDGM Staircase, LDGM Triangle, two large block codes, and Reed-Solomon. Thanks to this analysis, we define several recommendations on how to best use these codes, depending on the test case and on the channel, which turns out to be of utmost importance.

“…But in that case we introduce additional parameters like the loss model and the loss ratios. In contrast our approach avoids these problems, is more universal, simulates lossy transmissions with a random carousel like scheme, and is in line with transmissions like data broadcasting to cars [2], DVB IP Datacast [8], or a video streaming approach like [6].…”

“…Data broadcasting to cars (e.g. [2]), video delivery over satellites, DVB-T/H using "IP Datacast" (IPDC) [8] are possible applications for such types of transmissions. Because there is no back channel, no repeat request mechanism can be used that would enable the source to adapt its transmission according to the feedback information sent by the receiver(s).…”

Abstract. With many multimedia delivery schemes a client does not necessarily receive a given media content entirely (e.g. router congestions can lead some information to be lost). Mechanisms like error concealment and error resilient video coding allow the receiver to deal with partially received data and to play the content, with decreased quality though. Packet-level Forward Error Correction (FEC) can be used as a complementary technique to counter the effects of losses and reconstruct the missing packets. However if the number of packets received is too low for the FEC decoding process to finish, the received parity packets may turn out to be useless, and finally more source packets may be unavailable to the application than if FEC had not been used at all. This paper analyzes the adequacy of the LDGM Staircase, LDGM Triangle and RSE FEC codes to offer a partial reliability service for media content distribution over any kind of packet erasure channel, that is to say a service that enables a receiver to reconstruct parts of the content even if the FEC decoding process has not finished. We analyze this service in the context of a broadcasting system having no feedback channel and that offers media content distribution, like Digital Video/Audio Broadcasting.
