Digital video recorder compatible receiver with trick play image enhancement

Claims

I claim:

1. A digital video tape recorder (VTR) compatible receiver for receiving a digital video data stream output by a digital VTR, the video data stream including normal play video data output by the digital VTR during normal VTR playback operation, and trick play video data and trick play video data processing commands output by the digital VTR during trick playback operation, each trick play video data processing command including an instruction for processing the trick play video data, the receiver comprising:

a digital VTR port adapted for coupling the receiver to the digital VTR and for receiving from the digital VTR the digital video data stream including the trick play video data and the trick play video data processing commands output by the digital VTR during trick playback operation, the received trick play video data including a subset of the normal play video data; and

trick play video data processing means coupled to the digital VTR port, for performing video data processing operations on the trick play video data received from the digital VTR as a function of a received trick play video data processing command, the trick play video processing means processing the subset of normal play video data included in the trick play video data to compensate for normal play video data intentionally omitted by the VTR from the subset of normal play video data.

2. The receiver of claim 1, wherein the trick play video data processing means includes a two dimensional spatial filter for performing spatial filtering of the subset of normal play video data in response to a first trick play command.

3. The receiver of claim 1, wherein the trick play video data processing means includes a temporal filter for performing temporal filtering of the subset of normal play video data in response to a second trick play command.

4. The receiver of claim 1, wherein the trick play video data processing means includes a temporal filter for performing temporal filtering on the subset of normal play data in response to a first trick play command and a spatial filter for performing spatial filtering on the subset of normal play video data in response to a second trick play command.

5. The receiver of claim 1, further comprising a transport and priority decoder circuit that receives the video data and trick play video data processing commands, and performs video transport depacketization and priority decoding on the trick play video data received from the digital VTR to generate video codewords, the transport and priority decoder being responsive to the trick play video data processing commands to enable trick play video transport depacketization and priority decoding.

6. The receiver of claim 5, further comprising a video decoder coupled to the transport and priority decoder circuit, the trick play video data processing means, and adapted for coupling to a display circuit, the video decoder circuit receiving video codewords from the transport and priority decoder circuit and decoding the video codewords, the trick play video processing means performing video data processing on the video codewords received by the video decoder in response to the trick play video data processing commands.

7. The receiver of claim 6, wherein trick play video processing means includes a two dimensional spatial filter for performing spatial filtering of the video codewords in response to a first trick play video data processing command.

8. The receiver of claim 6, wherein the trick play video data processing means includes a temporal filter for performing temporal filtering of the video codewords in response to a second trick play video data processing command.

9. The receiver of claim 6, wherein the trick play video data processing means includes a temporal filter and a spatial filter for performing temporal filtering and spatial filtering, respectively, of the trick play video data in response to trick play video data processing commands.

10. The receiver of claim 5, further comprising a tuner module coupled to the digital VTR port and adapted for receiving a radio frequency signal, the tuner module demodulating, trellis decoding and de-interleaving the received radio frequency signal to generate transport data packets.

11. A digital video tape recorder (VTR) compatible receiver for receiving a video data stream output by a digital VTR, the video data stream including normal play video data output by the digital VTR during normal VTR playback operation, and trick play video data and trick play video data processing commands output by the digital VTR during trick playback operation, the receiver comprising:

a tuner module adapted for coupling to the digital VTR and for receiving from the digital VTR the trick play video data stream including the trick play video data and the trick play video data processing commands output by the digital VTR during trick playback operation, the trick play video data including a subset of the normal play video data; and

trick play video data processing means coupled to the tuner module, for performing video data processing operations on the trick play video data received from the digital VTR as a function of a received trick play video data processing command, the video processing means processing the subset of normal play video data included in the trick play video data to compensate for normal play video data intentionally omitted by the VTR from the subset of normal play video data.

12. The receiver of claim 11, wherein the trick play video data processing means includes a spatial filter for performing spatial filtering of the subset of normal play video data received from the digital VTR in response to a first trick play command.

13. The receiver of claim 12, wherein the trick play video data processing means includes a temporal filter for performing temporal filtering of the subset of normal play video data in response to a second trick play video data processing command.

14. A receiver comprising:

a tuner module adapted for coupling to a video tape recorder (VTR) and for receiving a video data stream from the digital VTR, the video data stream including normal play video data output by the digital VTR during normal VTR playback operation, and trick play video data output by the VTR during trick playback operation, the trick play video data including a subset of the normal play video data; and

trick play video data processing means coupled to the tuner module, for detecting the receipt of trick play video data from the digital VTR and for performing video data processing operations on the trick play video data received from the digital VTR to compensate for the absence of normal play video data intentionally omitted by the VTR from the subset of normal play video data included in the trick play video data.
