Embodiment Construction

[0024] now refer to figure 1 , which is a half diagram, half block diagram of a managed caching system 10 constructed and operative in accordance with an embodiment of the present invention.

[0025] figure 1 A client 12 is shown sharing a screen 16 with two other clients 14 . Screen sharing is assisted by the management cache system 10 . It will be appreciated that the content of screen 16 may change frequently or remain constant over an extended period of time.

[0026] The managed cache system 10 can enhance collaborative product interoperability when some type of standardized video format is used to transmit screen content. Standardized video formats may require more bandwidth than individual video formats. It should be noted that the managed cache system 10 can also be implemented using a personal video format.

[0027] as will be combined Figure 3 to Figure 19 As described in detail, the managed caching system 10 can enhance collaborative product interoperability ...

Abstract

In one embodiment, a managed cache system, includes a cache memory to receive storage units via an uplink from a transmitting client, each storage unit including a decodable video unit, each storage unit having a priority, and enable downloading of the storage units via a plurality of downlinks to receiving clients, and a controller processor to purge the cache memory of one of the storage units when all of the following conditions are satisfied: the one storage unit is not being downloaded to any of the receiving clients, the one storage unit is not currently subject to a purging exclusion, and another one of the storage units now residing in the cache, having a higher priority than the priority of the one storage unit, arrived in the cache after the one storage unit. Related apparatus and methods are also described.

Description

technical field [0001] The present invention relates to screen sharing, in particular to the management of screen sharing cache. Background technique [0002] By introduction, real-time screen sharing has become a must-have feature for many collaboration products. With the rapid growth of mobile devices, this popularity has created new challenges for collaborative products. Collaborative products usually require interoperability of different types of devices, service providers and products, concurrency to support multi-point communication and adaptability to enhance the business value of suppliers and customers. Contents of the invention [0003] A managed buffering system comprising: a buffer memory for receiving a plurality of storage units via an uplink from a transmission client, each storage unit comprising a decodable video unit, each storage unit having a priority selected from a plurality of priority levels stage, and enabling the storage unit to be downloaded to...
