摘要： Scalable empirical testing of media file playback utilizes test hooks in each media player to support simulated human interaction and playback monitoring. A media crawler catalogs media files accumulated in a media file database to create a wordlist. One or more scalable instances of media tester accesses the wordlist to select items of work linked to media files. Work items and/or operating modes of media tester specify test parameters such as performance profiles or further define testing such as specifying repetitious playback on one or more media players. Media files are downloaded to and played by a scalable number of media players. Playback performance is monitored, analyzed and reported. Failure reports are accompanied by instructions to reproduce failures and cross-references to content or source code in media files. Failures can be audited by additional work items for follow-up testing.

摘要： A receiver may train its equalizer using consecutive pilot bursts, divide the traffic between the consecutive pilot bursts into multiple sub-segments, and interpolate the trained equalizer coefficients to obtain the coefficients for equalizing one or more of the sub-segments. The receiver may also determine signal to interference and noise ratio (SINR) values based on each of the consecutive pilot bursts, and interpolate the SINR for decoding one or more of the sub-segments. The receiver may be an access terminal receiver operating in a code division multiple access (CDMA) cellular system.

摘要： A system and method of performing re-synchronization for a Digital Video Broadcasting over Handheld (DVB-H) receiver comprises performing a time division multiplexing (TDM) data burst transmission sequence on bits of data received by the DVB-H receiver; performing a data bit re-synchronization sequence on the DVB-H receiver; and reducing a re-acquisition time at every stage of the data bit re-synchronization sequence, wherein the reducing process results in a reduction in the time to perform the re-synchronization for the DVB-H receiver, wherein the reduction in the time to perform the re-synchronization for the DVB-H receiver is greater than one-half of the time required to perform the re-synchronization for the DVB-H receiver absent the reducing of the re-acquisition time at every stage of the data bit re-synchronization sequence.
