Benefits of technology
This approach allows for efficient and robust transmission of high-quality HDTV and SDTV content over wireless networks, optimizing power consumption and handling channel conditions to ensure reliable multimedia services.
Problems solved by technology
There are also significant challenges in deploying broadcast services to mobile user equipment.
Another consideration is the Doppler effect in moving user equipment, which may cause inter-symbol interference in received signals.
However, broadcasting may often require high bit rate data transmission at rates higher than could be supported by existing mobile communications networks.
Furthermore, downlink communication paths which may be utilized for communicating information to one or more receivers may deteriorate.
In this regard, significant delays may be experienced at the receiver side for receiving the communicated information.
In addition, quality of the received information communicated via a deteriorated downlink communication path may also decrease.

Embodiment Construction
[0025]Certain embodiments of the invention may be found in a method and system for communicating information via a plurality of different networks within a multistandard wireless communication system. A multistandard wireless communication system may comprise a plurality of different networks and corresponding base stations. Each network may utilize a different communication protocol. For example, one or more of the networks within the multistandard communication system may comprise a DVB-H communication network, a cellular communication network, an IEEE 802.11 wireless local area network (WLAN), and / or an IEEE 802.16 wireless metropolitan area network (WMAN).
[0026]A high definition television (HDTV) signal may be received at a mobile terminal via a DVB-H downlink communication path. A standard definition television (SDTV) signal may be simultaneously received at the mobile terminal via a cellular downlink communication path. The SDTV signal may comprise NTSC-encoded or PAL-encoded ...

Methods and systems for communicating information in a network are disclosed herein and may include receiving, at a mobile terminal, a first media signal via a first downlink communication path. A second media signal may be simultaneously received at the mobile terminal via a second downlink communication path. The first media signal and the second media signal may comprise the same media content. The first media signal received via the first downlink communication path and the second media signal received via the second downlink communication path may be selected in the mobile terminal for processing. The selection may be based on at least one downlink channel condition indicator corresponding to the first media signal or the second media signal.
