- This writing discloses a data management method for recorded programs stored on a digital recording device.
- VCR video cassette recorders
- PVR personal video recorders
- DVR digital video recorders
- PVRs and DVRs are stored digitally on an internal storage device (e.g., a hard disk drive).
- a user can program the device to record a television program to the hard drive for viewing at a later time.
- a user can subscribe to service that provides downloadable channel guides that can be used to record every instance of selected television programs whenever they are broadcast. Due to the amount of programming available to the typical user, often hundreds of channels, and the finite amount of storage space of a PVR or DVR, it is common for a user to fill the storage space of the hard drive. When the storage space is filled, no more television programs can be recorded.
- the user has the option of deleting the entire television program. Deleting a television program releases the storage space used to store the television program, allowing the recording of other television programs. However, a user may not have enough time to view the entire recorded program, so the user does not delete the television program, saving it so that the remaining portion can be viewed at a later time.
- the digital recording device is a personal video recorder (PVR). In another embodiment, the digital recording device is a digital video recorder (DVR).

- graphical user interface 300 is rendered on a display of an audio/video device. By interacting with graphical user interface 300, for example by using a remote control, a user can select a user selection.
- Graphical user interface 300 is rendered in response to a user stopping playback of a recorded program.
- User selection 310 provides for a user to continue playback of the recorded program.
- User selection 320 provides for a user to delete the entire recorded program.
- User selection 330 provides for a user to delete the viewed portion of the recorded program.

- the first recorded program is concatenated at an Intra frame of said MPEG video stream.
- An MPEG video stream comprises both video and audio components.
- the video component comprises Intra frames (I frames), predicted frames (P frames), and bi-directional frames (B frames).
- I frames comprise ' the information in the picture itself, such as a JPEG image. Following I frames will be one or more P frames.
- the P frame comprises information based only the differences between the P frame and the I frame it is based on. Between I and P frames are B frames which are based on the nearest I or P frames both before and after them. Because an Intra frame comprises information for a complete image, the MPEG video stream for the first recorded program is concatenated at an Intra frame. In one embodiment, the first recorded program is concatenated before the last I frame rendered prior to stopping the MPEG video stream.
- memory e.g., storage
- memory associated with the rendered portion is released prior to the last I frame rendered prior to stopping the MPEG video stream.
- a byte offset can be calculated to that point in the digital file (e.g., the first recorded program).
- the number of bytes calculated by the byte offset is deleted from the first recorded program.
- the total number of bytes of the program prior to the deletion minus the byte offset represents the remaining portion of the first recorded program.
- the number of seconds remaining in the first recorded program can be calculate based on the last I frame rendered. It should be appreciated that any reference files associated with the first recorded program that are required for playback are truncated at the same proportions as the first recorded program.
- Releasing the memory allows for the memory to be available to store data associated with a second recorded program. Furthermore, the remaining portion of the first recorded program is not deleted, and thus is available for presentation to the audio/video device.
- Steps 450-470 of process 400 illustrate steps in a process for playback of a first recorded program once a portion of the first recorded program has been deleted in accordance with one embodiment of the present invention.
