    摘要: Aspects of the subject matter described herein relate to offload reads and writes. In aspects, a requestor that seeks to transfer data sends a request for a representation of the data. In response, the requestor receives one or more tokens that represent the data. The requestor may then provide one or more of these tokens to a component with a request to write data represented by the one or more tokens. In some exemplary applications, the component may use the one or more tokens to identify the data and may then read the data or logically write the data without additional interaction with the requestor. Tokens may be invalidated by request or based on other factors.

    摘要: Described are embodiments which allow token-based file operations. The client may request a special offload file operation that is formatted according to a file access protocol. The file operation may be an offload read operation or an offload write operation. In an offload read operation, the client requests that data be logically read from a stored file, or a portion thereof. In response, the file server provides a response that includes a token that represents the logically read data. In some embodiments, the file server may return a response with a token that represents less than all of the requested data if for some reason it cannot provide a token that represents all of the data. The token can then be used by the client in a subsequent offload write operation. In embodiments, the tokens represent immutable data that can be safely and securely used across servers and clients.

    摘要: Aspects of the subject matter described herein relate to a zero token. In aspects, a zero token may be used to represent one or more zeroes in an offload write command. A component receiving an offload write command with the zero token is free to write the zeroes in a variety of ways including, for example, changing data structures the component uses to represent the zeroes, issuing another command that writes zeroes, writing physical zeroes, and so forth. A component receiving an offload write command with the zero token does not need to verify that the zero token was obtained from a successful offload read or that the zero token is still valid. In response to an offload read request, a component may provide the zero token to represent all or a portion of the data associated with the offload read request.

    摘要: Aspects of the subject matter described herein relate to an offload provider. In aspects, an offload provider may provide a token that represents data. The offload provider may be expected to ensure that the data the token represents will not change while the token is valid. The offload provider may take actions to ensure the immutability of the data. The actions may be taken, for example, in conjunction with receiving an offload read and/or offload write, and/or in conjunction with receiving another write that, if allowed to proceed, would otherwise change the data represented by the token.

    摘要: A digital video recorder stores digital video streams having sequences of encoded frames that are predominantly non-keyframes. The digital video recorder synthesizes keyframes for the digital video stream by decoding the frames in sequence and occasionally capturing the state of the decoder as it decodes the frames. The decoder states are stored in a state index in association with the frames. During playback at normal or accelerated speeds, the digital video recorder is capable of random accelerated access of any frame in the digital video stream. A decoder state associated with the accessed frame is retrieved from the state index and used to begin decoding at or near the accessed frame. The decoder state initializes a playback decoder to the state that enables complete decoding and rendering of the accessed frame without having to decode multiple frames previous to the accessed frame, thereby minimizing time delays in playback.
