Techniques for monitoring local and/or remote file systems by a synchronization component (e.g., client/server) of a cloud-based platform are disclosed. In some embodiments, a method of building synchronization events by a synchronization component (e.g., a synchronization server/client) includes obtaining a set of items that have been changed and their new states and retrieving last known states of the set of items that are stored in a reference snapshot inside a filesystem scanner. The method further includes generating differences between the new states and the last known states of the set of items as item changes and utilizing information provided by the item changes to translate the item changes into synchronization events for execution on the opposing file system. A method of handling failed synchronization events by a synchronization component of the cloud-based platform by collapsing a subsequent event with the failed synchronization event is also disclosed.

Systems and methods for maintaining and updating file system shadows by a synchronization client of a cloud-based platform. In some embodiments, an executor of the synchronization client can execute an action on an item in the local file system which changes the state of the item from an old state to a new state. The synchronization client updates the file system shadows with the new state of the item via an interface to facilitate generation of a synchronization event for the change to the item, that would otherwise go undetected if the change to the item was immediately reversed. In some embodiments, methods for providing shadow consistency and enhancing concurrent access to shadows are implemented by the synchronization client in maintaining and updating the file system shadows.

A system or method selects among multiple tuners to tune a particular channel. A request is received to tune a first channel. In response to this request, a first tuner is assigned to tune the first channel. A request is received to tune a second channel. If the program tuned by the first tuner is not being recorded, the first tuner is assigned to tune the second channel. If the program tuned by the first tuner is being recorded, the second tuner is assigned to tune the second channel.

Techniques are described to provide content access. In an implementation, a determination is made at a client that a high-definition channel has content that matches content provided by a standard-definition channel. Access is provided to the content via the high-definition channel and access is restricted to the content via the standard-definition channel up the client is capable of outputting the content and high definition.

Content access

Methods, systems and computer program products for scheduling retrieval of shared content. Certain embodiments commence upon storing shared content at a collaboration system that is connected to a plurality of user devices by a network. After gathering one or more environmental conditions that correspond to at least one of the plurality of user devices, a time or a plurality of times is predicted, the predicted time or times corresponding to when conditions such as a user's device location or network strength conditions or other environmental conditions that affect the user devices might change. Based on the predicted times, a retrieval schedule is defined. The retrieval schedule includes instructions for initiating downloading of portions of the shared content from the collaboration system to the user device. Initiation of the start of downloading may be calculated to cause just-in-time downloading that completes just before the time of a predicted change in conditions.

Scheduled retrieval of shared content

A unified recording format allows both recorded programs and paused buffered broadcasts to be stored in memory as a common virtual stream. As content is received on a channel, it is placed into the virtual stream with newer content at the start of the stream and progressively aging content migrating farther downstream. A front section of the stream effectively operates as a pause buffer, as the currently tuned broadcast program is recorded in this section and is responsive to pause/resume commands. Recorded programs are also stored as part of the same virtual stream. Pointers are used to identify the boundaries of the pause buffer, as well as the beginning and end of each recorded program in the virtual stream.
