    摘要： Methods and apparatus for service acquisition in a broadcast system. In an aspect, a method includes detecting whether a loss of service has occurred, and initiating acquisition attempts during an aggressive acquisition phase if a loss of service has occurred, wherein a backoff time interval between successive acquisition attempts is constant or increased, and wherein the aggressive acquisition phase ends when service acquisition is achieved or a selected number of acquisition attempts have been performed. An apparatus includes interface logic configured to detect whether a loss of service has occurred, and processing logic configured to initiate acquisition attempts during an aggressive acquisition phase if a loss of service has occurred, wherein a backoff time interval between successive acquisition attempts is constant or increased, and wherein the aggressive acquisition phase ends when service acquisition is achieved or a selected number of acquisition attempts have been performed.

    摘要： A wireless communications device configured to operate in a multimedia broadcast system is disclosed. The wireless communications device includes a receiver configured to receive a plurality of video streams each comprising intra-coded and inter-coded video frames. The wireless communications device also includes a video decoder, and a processing unit configured to switch the video streams to the video decoder. The processing unit is further configured to receive a prompt to switch from a first one of the video streams to a second one of the video streams, and in response to the prompt, delay switching to the second one of the video streams until an intra-coded video frame is received in the second one of the video streams.

    摘要： Apparatus is disclosed for automatically and simultaneously cleaning both sides of a plurality of workpieces. The workpieces are illustratively thin, fragile slices of brittle material, such as single-crystal silicon wafers. These workpieces are supplied to the cleaning apparatus within a cassette. The cleaning apparatus includes a cassette receiving station, a processing station and guide means extending from the cassette receiving station through the processing station. The guide means is adapted to receive edge portions of the workpieces. A transfer arm is extended from a retracted position through the cassette so that a first portion of the transfer arm pushes a workpiece along the guide means through the processing station. The transfer arm is then retracted and a second portion of the transfer arm pushes the workpiece along the guide means back through the processing station and into the cassette. The cassette is then moved so that the next workpiece to be processed is in position adjacent the guide means. The processing station extends on both sides of the guide means and includes a scrubbing station. In the region of the scrubbing station, the guide means is arranged so that the entire workpiece surface is exposed to the scrubbing station.
