Abstract

A transportable digital video recorder system provides a transportable DVR containing a processor and persistent storage device storing a plurality of digital streams and is inserted into an authorized receiving device or a docking station. The system allows a receiving device to select a specific digital stream from the persistent storage device which is output to the receiving device and displayed to a user. User control commands are accepted via the receiving device and sent through the system and allow the user to view and listen to stored digital streams with at least the following functions: variable rate fast forward and rewind, frame step, index, pause, variable rate reverse play, variable rate play, and play.

Claims

exact text as granted — not AI-modified
1 . A method for a small form factor transportable digital video recorder (DVR), comprising:

         2 . The method of  claim 1 , further comprising:
 receiving analog signals from the receiving device;   converting, by the small form factor transportable DVR, the analog signals into a digital stream; and   storing the digital stream on the storage device.   
     
     
         3 . The method of  claim 1 , further comprising:
 receiving digital video signals from the receiving device;   converting, by the small form factor transportable DVR, the digital video signals into a digital stream; and   storing the digital stream on the storage device.   
     
     
         4 . The method of  claim 1 , further comprising:
 accepting digital television broadcast signals using a plurality of input signal tuners in the small form factor transportable DVR;   wherein each of the tuners is individually tuned to a specific broadcast signal;   converting digital television broadcast signals into a digital stream; and   storing the digital stream on the storage device.   
     
     
         5 . The method of  claim 1 , wherein the small form factor transportable DVR will only allow access to digital streams on the storage device by an authorized receiving device. 
     
     
         6 . The method of  claim 1 , further comprising:
 storing an electronic program guide on the storage device in the small form factor transportable DVR; and   wherein the small form factor transportable DVR delivers portions of the electronic program guide to the receiving device upon request from the receiving device.   
     
     
         7 . The method of  claim 1 , further comprising:
 upon the small form factor transportable DVR being communicatively connected to the receiving device, the small form factor transportable DVR authenticating the receiving device.   
     
     
         8 . The method of  claim 1 , wherein the storage device is at least one microdrive. 
     
     
         9 . The method of  claim 1 , wherein the small form factor transportable DVR is communicatively connected to the receiving device via at least one of: USB, Firewire, or docking station. 
     
     
         10 . The method of  claim 1 , wherein the storage device is at least one solid state memory device. 
     
     
         11 . The method of  claim 1 , wherein the small form factor transportable DVR is a plug-in module. 
     
     
         12 . An apparatus for a small form factor transportable digital video recorder (DVR), comprising:
 a storage device in a small form factor transportable DVR;   a processor on the small form factor transportable DVR, the small form factor transportable DVR is communicatively connected to a receiving device, the processor in the small form factor transportable DVR communicates with the receiving device;   at least two digital streams stored on the storage device;   a command receiving subsystem in the small form factor transportable DVR that receives a selection from the receiving device of a specific digital stream among the plurality of digital streams stored on the storage device in the small form factor transportable DVR;   a digital stream selection subsystem in the small form factor transportable DVR that selects the specific digital stream from the storage device among the at least two digital streams stored on the storage device and sends the specific digital stream to the receiving device;   in response to receiving a user command via the receiving device, the command receiving subsystem controls a delivery rate and direction of the specific digital stream to the receiving device to perform at least one of: variable rate fast forward, variable rate rewind, pause, or play functions.   
     
     
         13 . The apparatus of  claim 12 , further comprising:
 an analog signal receiver that receives analog signals from the receiving device;   an analog signal to digital signal converter that converts the analog signals into a digital stream; and   a storing subsystem that stores the digital stream on the storage device.   
     
     
         14 . The apparatus of  claim 12 , further comprising:
 a digital signal receiver that receives digital video signals from the receiving device;   a digital signal converter that converts the digital video signals into a digital stream; and   a storing subsystem that stores the digital stream on the storage device.   
     
     
         15 . The apparatus of  claim 12 , further comprising:
 a plurality of input signal tuners on the small form factor transportable DVR;   wherein the plurality of tuners accept digital television broadcast signals;   wherein each of the tuners is individually tuned to a specific broadcast signal;   a digital signal converter that converts digital television broadcast signals into a digital stream; and   a storing subsystem that stores the digital stream on the persistent storage device.
