Abstract

A method of providing a video signal for display of a stream of video data (200) at a rate other than real-time, the video data being built up from frames, includes real-time rendering of non-contiguous segments of the stream of video data having multiple subsequent frames to a first rendered stream, non-real-time rendering of the stream of video data by rendering pre-determined non-subsequent frames at a speed other than real-time to a second rendered stream; and multiplexing the first rendered stream and the second rendered stream for simultaneous display on a display device (150), wherein the first rendered stream is displayed on a first part (310) of the display device, and the second rendered stream is displayed on a second part (320) of the display device.

Claims

1. A method of providing a video signal for display of a stream of video data at a rate other than real-time, the stream of video data being built up from subsequent frames, the method comprising the steps of:

selecting a plurality of non-contiguous segments of the stream of video data, each of said non-contiguous segments comprising multiple subsequent frames;

real-time rendering said plurality of non-contiguous segments in a concatenated manner to form a first rendered stream having a first rate other than real-time;

selecting a plurality of pre-determined non-subsequent frames of said stream of video data;

non-real-time rendering said pre-determined non-subsequent frames in a concatenated manner to form a second rendered stream having a second rate other than real-time; and

multiplexing the first rendered stream and the second rendered stream for simultaneous display on a display device,

wherein the first rendered stream is displayed on a first part of the display device and the second rendered stream is displayed on a second part of the display device; and

wherein the second rate is greater than the first rate and real-time.

2. The method according to claim 1, wherein the second part of the display device is significantly smaller than the full size of the display device and the first part of the display is the complement to the second part.

3. The method according to claim 1, wherein the first part of the display device is significantly smaller than the full size of the display device and the second part of the display is the complement to the second part.

4. The method according to claim 1, wherein the first part of the display device and the second part of the display device have mutually equal sizes.

5. The method according to claim 1, wherein the method further comprises the steps of:

providing a first bar representative of the stream of video data; and

indicating on the first bar a location in the stream of video data of the first rendered stream that is displayed on the first part of the display device.

6. The method according to claim 1, wherein the method further comprises the steps of:

providing a second bar representative of the stream of video data; and

indicating on the second bar a location in the stream of video data of the second rendered stream that is displayed on the second part of the display device.

7. The method according to claim 5, wherein the method further comprises the step of:

indicating on the first bar a location in the stream of video data of the second rendered stream that is displayed on the second part of the display device.

8. The method according to claim 1, wherein the method further comprises the step of:

providing an indicator indicative of a direction of the non-real-time rendering.

9. The method according to claim 1, further comprising the step of:

providing an audio signal at real-time, synchronized with the first rendered stream.

10. An apparatus for providing a video signal for display of a stream of video data at a rate other than real-time, the stream of video data being built up from subsequent frames, the apparatus comprising:

first means for selecting a plurality of non-contiguous segments of the stream of video data, each of said plurality of non-contiguous segments comprising multiple subsequent frames;

a first rendering unit for real-time rendering the plurality of non-contiguous segments in a concatenated manner to form a first rendered stream having a first rate other than real-time;

second means for selecting a plurality of pre-determined non-subsequent frames of said stream of video data;

a second rendering unit for non real-time rendering of the plurality of pre-determined non-subsequent frames in a concatenated manner to form a second rendered stream having a second rate other than real-time; and

a multiplexer for multiplexing the first rendered stream and the second rendered stream for simultaneous display on a display device,

wherein the first rendered stream is displayed on a first part of the display device and the second rendered stream is displayed on a second part of the display device; and

wherein the second rate is greater than the first rate and real-time.

11. A non-transitory computer-readable storage medium having stored thereon programmable instructions configured for being executed by at least one processor for performing a method suitable for providing a video signal for display of a stream of video data at a rate other than real-time, the stream video data being built up from subsequent frames, the method comprising:

Selecting a plurality of non-contiguous segments of the stream of video data, each of said plurality of non-contiguous segments comprising multiple subsequent frames;

real-time rendering of the plurality of non-contiguous segments in a concatenated manner to form a first rendered stream having a first rate other than real-time;

selecting a plurality of pre-determined non-subsequent frames of said stream of video data;

non-real-time rendering of the plurality of pre-determined non-subsequent frames in a concatenated manner to form a second rendered stream having a second rate other than real-time; and

multiplexing the first rendered stream and the second rendered stream for simultaneous display on a display device,

wherein the first rendered stream is displayed on a first part of the display device and the second rendered stream is displayed on a second part of the display device; and

wherein the second rate is greater than the first rate and real-time.

12. A method of providing a video signal for display of a stream of video data at a rate other than real-time, the stream of video data being built up from subsequent frames, the method comprising the steps of:

Selecting a plurality of non-contiguous segments of the stream of video data, each of said plurality of non-contiguous segments comprising multiple subsequent frames;

real-time rendering of the plurality of non-contiguous segments in a concatenated manner to form a first rendered stream having a first rate other than real-time;

selecting a plurality of pre-determined non-subsequent frames of said stream of video data;

non-real-time rendering of the plurality of pre-determined non-subsequent frames in a concatenated manner to form a second rendered stream having a second rate other than real-time;

multiplexing the first rendered stream and the second rendered stream for simultaneous display on a display device;

wherein the first rendered stream is displayed on a first part of the display device and the second rendered stream is displayed on a second part of the display device; and

wherein the second rate is greater than the first rate and real-time;

providing a first bar representative of the stream of video data;

indicating on the first bar a location in the stream of video data of the first rendered stream that is displayed on the first part of the display device; and

indicating on the first bar a location in the stream of video data of the second rendered stream that is displayed on the second part of the display device.
