Video playback device for channel browsing
First Claim
1. A video playback device, provided in a P2P-based network, comprising:
- a channel pre-cached buffer, for storing a plurality of video blocks corresponding to a number of pre-cached channels;
a display interface, for receiving a request for channel browsing from a viewer and executing playback of the video blocks pertaining to a selected channel indicated on the request; and
an agent mechanism, for receiving the request for channel browsing from the display interface, obtaining a seed/peer list pertaining to the selected channel indicated on the request, and downloading the video blocks from seed and/or peer nodes based on the seed/peer list;
characterized in thatthe agent mechanism applies an automatic refreshing mechanism for updating the corresponding video blocks to each pre-cached channel by supplying the most updated video blocks in the channel pre-cached buffer, wherein when the agent mechanism receives the request for channel browsing, the automatic refreshing mechanism stops refreshing, a predetermined number W of video blocks of the selected channel are received in the channel pre-cached buffer, and the automatic refreshing mechanism is started again to refresh the other pre-cached channels that have not been selected after the predetermined number W of video blocks of the selected channel are received in the channel pre-cached buffer.

11. A channel browsing method, comprising the steps of:
-
(1) providing a video playback device which comprises a channel pre-cached buffer, a display interface and an agent mechanism for connecting to a P2P-based network; (2) sending a request for channel browsing to the agent mechanism from a viewer on the display interface that indicates a selected channel; (3) receiving the request at the agent mechanism from the display interface and starting to obtain a seed/peer list pertaining to the selected channel indicated on the request; (4) starting to download the video blocks at the agent mechanism for the selected channel from seed and/or peer nodes in the P2P-based network; (5) continuing to download the video blocks for the selected channel at the agent mechanism until the number of video blocks reaching to a predetermined number W in the channel pre-cached buffer; (6) executing playback of the selected channel at the display interface while receiving the predetermined number W of the video blocks pertaining to the selected channel; and (7) starting to implement an automatic refreshing mechanism at the agent mechanism for refreshing the video blocks corresponding to each pre-cached channel except for the selected channel by supplying the most lately video blocks in the channel pre-cached buffer, wherein when the agent mechanism receives the request for channel browsing, the automatic refreshing mechanism stops refreshing, predetermined number W of video blocks of the selected channel are received in the channel pre-cached buffer, and the automatic refreshing mechanism is started again to refresh the other pre-cached channels that have not been selected after the predetermined number W of video blocks of the selected channel are received in the channel pre-cached buffer. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
