Internet protocol broadcasting
Methods, apparatuses, and systems are provided for improving utilization of a communications system through various atom-based techniques for enhancing the viewing experience for Internet protocol content. Some embodiments exploit atom-based processing to determine which content atoms to broadcast (e.g., multicast) over which channels to which subscribers. Other embodiments make atom-based filtering, caching, and/or other determinations at the user terminal. For example, low-level (e.g., physical layer) filtering may be used to limit the amount of user-layer processing needed, and to facilitate delivery of content to those users most likely to desire that content. Still other embodiments allow users to create customized channels of cached content for viewing as a shared channel. Embodiments include techniques for addressing synchronization of channel content and viewing, and social networking, for subscribers to the shared channel. The shared channels may be further used to facilitate social networking among subscribers.

18. The method of claim 17 , wherein similarity between the existing content unit and other content units in the channel increases a value of the existing content unit.
19. The method of claim 17 , wherein similarity between the existing content unit and other content units in the channel decreases a value of the existing content unit.
20. The method of claim 16 , wherein the one or more channel management preferences comprises an indication of relative targets of an amount of fresh data for a channel.
21. The method of claim 20 , wherein a first value of a first channel content unit in a first channel under the relative targets is higher than a second value of a second channel content unit in a second channel that is at or above the relative targets.
22. The method of claim 1 , further comprising:
determining content retention at a user terminal at least in part based on the adjusted value relative to the existing content unit.
23. The method of claim 1 , wherein the client dictionary comprises a client cache.
24. A system for adjusting a value of a candidate content unit in a communications system relative to an existing content unit of a client dictionary, comprising:
a processor; and
a non-transitory computer readable storage medium comprising instructions that when executed by the processor cause the communication system to:
identify a candidate content unit having a baseline value;
determine one or more parameters regarding an existing content unit of the client dictionary, the existing content unit comprising content that is replaceable in the client dictionary by the candidate content unit; and
