Embodiment Construction

[0012] The present invention will mainly be described in the context of specific embodiments; however, those skilled in the art who have been inspired by the teachings herein will realize that the present invention is also applicable to other technical fields and / or embodiments.

[0013] In general, this article describes and describes the cross-layer decoding of satellite mobile TV broadcasts in a multimedia multicast broadcast network, but various other capabilities can also be presented in this article. In particular, various embodiments contemplate the use of satellite-based services to enable broadcasting and / or multicasting of multimedia content, such as television programs, movies, etc., to mobile devices generally adapted to terrestrial wireless networks. For example, multimedia broadcast multicast services may include, for example, multimedia broadcast multicast services (MBMS) supported in existing Global System for Mobile communications (GSM) and Universal Mobile Teleco...

Abstract

Methods and apparatus providing error protection in multicast- broadcast service by encoding multimedia content according to a first protocol to provide a plurality of distinct video streams, coding each of the distinct video streams using respective coding protocols, wherein each coding protocol has associated with it corresponding descriptors and coefficients, and multiplexing the coded video streams toward a wireless network.

Description

Technical field [0001] The present invention relates generally to communication networks, and more specifically but not exclusively to mobile television broadcasting. Background technique [0002] The satellite system is economical for use as a broadcaster. Therefore, satellite broadcasting adapted to signals received by mobile device receivers, such as mobile device receivers that comply with Long Term Evolution (LTE) and other wireless standards, is appropriate. Unfortunately, satellite signals are susceptible to data loss due to long-term shielding in which the signal is blocked by bridges, buildings, or other structures. Therefore, when used for broadcasting within the context of mobile applications, signal loss due to long-term shielding can degrade the quality of user experience. Summary of the invention [0003] The various shortcomings in the prior art are solved by embodiments for providing error protection in multicast broadcast services through the following items: en...
