摘要： An adaptive error correction method for data transmission and the devices thereof are disclosed. By comparing the announced recovery data and data requested for error correction, no redundant join messages will be sent if the recovery data have been announced before. This will greatly reduce the number messages and save the band width of transmission.

摘要： In the context of IEEE 802.11 WLAN networks, enhancement to the Relaxed Deterministic Backoff (R-DEB) for random access of shared (Medium Access Control MAC) method. For all available candidate resource slots, a busy index is calculated that reflects the level of use/occupation in the past and infers a probability of use in the future by another concurring device. The method assumes the use of a sub-set of resource slots for transmission, and updates this set by replacing resource slots for which collisions are frequent with a not currently used candidate resource for which the busy index is the lowest. Passive Spoofing/overhearing of all resources for clear channel assessment (CCS) is used for resource monitoring purposes.

摘要： Trick mode play for controlling video content playback can be realized using a semantic based criterion in order to achieve a more uniform playback experience for the viewer, when that viewer wishes to observe the video content presented according to a selected semantic. In one embodiment of the method, semantics associated with shorter time intervals in the video content are replayed in trick mode play proportionally slower than semantics associated with longer time intervals, wherein the proportionally is determined, at least in part, to the time interval associated with each semantic. In various embodiments, semantics can include scenes, audio, metadata, tags, and the like. The semantics based trick mode play approach allows for a more uniform viewing experience, on a time duration basis, from one semantic to the next.

摘要： A system such as a multicast VOD system communicates content, e.g., delivers content or receives content, responsive to a user request for content and according to a schedule adapted to a user-specified acceptable latency for content delivery. The schedule may be modified to minimize initiation of delivery of content in response to the user's request. The schedule may also be modified to delay delivery of subsequent portions of the content as late as possible to allow subsequent requests to share a content stream while not exceeding the acceptable latency parameter specified by the user.
