摘要： Aspects of a method and system for redundancy-based decoding of video content in a wireless system are provided. A wireless receiver may determine whether a received multimedia data stream comprises video content and may select a redundancy-based decoder when video content is detected. The wireless receiver may be a wireless local area network (WLAN) receiver or a cellular receiver. Video content may be indicated by at least one flag in a preamble or a reserved field of the received multimedia data. The redundancy-based decoder may be a Viterbi decoder. The wireless receiver may enable a standard Viterbi decoder to decode portions of the multimedia data that do not comprise video content. The wireless receiver may generate at least one signal to select the redundancy-based decoder or the standard Viterbi decoder.

摘要： Methods and systems for distributed infrastructure for streaming data via multiple access points. Aspects of one method may include apportioning multimedia information among a plurality of transmitting devices based on feedback channel information received from a destination receiving device by, for example, a transmission controller device. The transmitting devices may transmit the multimedia information to the destination receiving device. A transmitting device that may not be apportioned multimedia information may transmit a probing signal. The destination receiving device may generate feedback channel information for a transmitting device, for example, based on the multimedia information or the probing signal received from the respective transmitting device. The apportioning of the multimedia information may be dynamically adjusted based on updated feedback channel information received from the destination receiving device.

摘要： Aspects of a method and system for redundancy-based decoding of voice content in a wireless local area network (WLAN) system are provided. A WLAN receiver may determine whether a decoded portion of a received packet comprises voice content and may select a redundancy-based decoder to decode a remaining portion of the packet when voice content is detected. The redundancy-based decoder may be a Viterbi decoder. The redundancy-based decoder may be selected to decode a determined number of subsequent packets or to decode subsequent packets for a determined amount of time. After decoding the remaining portion of the packet and any subsequent packets, the WLAN receiver may select a standard Viterbi decoder to decode additional received packets. The WLAN receiver may generate at least one signal to select the redundancy-based decoder and the standard Viterbi decoder.

摘要： Aspects of a method and system for providing visually related content description to physical layer are provided. A MAC layer and/or a PHY layer in a wireless communication device may be controlled for processing at least one media object in an audiovisual scene based on metadata information that corresponds to the audiovisual scene. The metadata information may result from, for example, MPEG-4 encoding of the audiovisual scene. Each media object may be forward error corrected based on a determined priority level, such as foreground and background priorities, that results from the metadata information. In this regard, the number of bits utilized for protection and/or the RF modulated scheme may be selected in accordance with the priority level. The RF modulation may be, for example, QPSK modulation or 16 QAM modulation. The metadata information and the processed media objects may then be wireless communicated.
