Abstract
A cache for a linear stream based cache system receives video data from a data source and transmits the video data to an application controlling a display for displaying the video data. The cache system includes an application memory storing first data, a cache memory, operatively connected to the application memory, and storing second data, and a data processor, operatively connected to the application and cache memories. The data processor controls the transmission of third data from the data source to the application via at least one of the application and cache memories responsive to an application file request. When the data processor determines that a sufficient amount of at least one of the first and second data is stored in at least one of the application and cache memories, respectively, the application accesses the first data in the application memory, and the data processor controls the transmission of the second data from the cache memory to the application memory, and the third data from the data source to the cache memory. In addition, when the data processor determines that the sufficient amount of at least one of the first and second data is not stored in at least one of the application and cache memories, respectively, the application accesses the first data in said application memory, and the data processor controls the transmission of the second data from the cache memory to the application memory, and the third data from the data source to the application memory.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
