Abstract
A data stream accessor seeks to simulate an uninterrupted bitstream for a decoder during network interruptions. The accessor performs a set of operations including receiving an available amount of image data and storing a current execution context of the call site, passing execution flow to the decoder, and performing a subset of operations. The subset includes receiving an indication of a desired amount of image data from the decoder. If a total amount of image data at the accessor is greater than or equal to the desired amount, the desired amount is transmitted to the decoder for decoding. Otherwise, and unless an error issues, a current execution context of the decoder is stored, execution flow is passed from the decoder to the call site, and the restorable execution context is loaded as the current execution context of the call site. The subset is repeated unless the image is completely decoded.
