Abstract

A system and method for permitting an end user to select a media stream and immediately experience the audio and video of that stream, in order to evaluate whether the stream is appropriate to the user'"'"'s interests and needs. The invention implements a multi-channel receiver that is actively receiving multiple streams, simultaneously. In a preferred aspect, the bandwidth requirements necessary to convey multiple streams, e.g., those communicated on the same network branch, is reduced. Further, the resource requirements of the multi-channel receiver device are reduced for enabling a user to select from among the received multiple streams. A novel user interface is provided that enables fast selection of a pre-acquired stream and, playback of the stream content immediately upon selection.

3. The method of claim 1, wherein the audible or visual reproduction for said user during said fast stream selection is at a quality level lower than that which is appropriate for the selected stream, said streaming being communicated by said server device at a lower bandwidth.

4. The method of claim 1, wherein prior to user selection of a stream, the step of running all streams at a limited quality, enabling said user to evaluate the content of alternative streams quickly but not their quality.

5. The method of claim 1, wherein said providing step c) further includes the step of initially providing said immediate audible or visual reproduction of said selected stream at said lower quality level;

and, after a predetermined time period, the step of initiating a full quality version of said selected stream for reproduction.

6. The method of claim 5, wherein the predetermined time period is a sampling period commensurate with user sampling of the stream at the lower quality level.

7. The method of claim 5, wherein a predetermined time period is set by a user as part of that user'"'"'s preferences.

8. The method of claim 2, wherein multiple streams that are activated simultaneously include an active stream selected from said interface and streams that may be potentially selected according to its position relative to a position of the selected stream via the interface.

9. The method of claim 7, wherein said streams that may be potentially selected by virtue of its proximate location to said selected stream are active at a lower fidelity

10. The method of claim 7, wherein a number L/T neighbors of the current selected stream are active wherein said “

L”

represents the stream latency and “

T”

represents the time for a user to move a pointer of said fast selection interface from one selecting position to another adjacent selecting position.

16. The system of claim 1, wherein said user interface device enabling fast selection includes a linear selector, comprising a linear selector window, capable of movement in a single dimension for pointing to one of multiple selecting positions.

11. A system for accessing multiple multi-media data streams for selection by a user, said system comprising:

multi-channel receiver device for receiving selected number of data streams broadcast from one or more server devices via a network connection;

user interface device having multiple stream selecting positions for enabling fast switching between stream selections; and

,

means for providing immediate audible or visual reproduction of a stream at said multi-channel receiver device in response to the fast selecting.

12. The system of claim 11, further comprising stream handler means for initiating simultaneous streaming for one or more said multiple streams from said one or more server devices via a network connection to enable a user to sample by viewing or listening to stream content immediately upon fast selecting.

13. The system of claim 11, wherein the audible or visual reproduction for said user during said fast stream selection is at a quality level lower than that which is appropriate for the selected stream, said multi-channel receiver device receiving a selected number of streams broadcast from a server device via a network connection at a lower bandwidth.

14. The system of claim 11, wherein said server device initially provides said selected stream at said lower quality level for initial audible or visual reproduction, and, after a predetermined time period, provides a full quality version of said selected stream for reproduction.

15. The system of claim 11, wherein said user interface device enabling fast selection includes a rotary dial including a rotary pointer knob for pointing to one of multiple selecting positions

17. The system of claim 12, wherein multiple streams that are activated simultaneously include an active stream selected from said interface and streams that may be potentially selected according to its position relative to a position of the selected stream via the interface.
