Abstract
Provided is a hybrid protocol which may provide web browsing service even by means of a low-performance set-top box using a virtualization server. The virtualization server separately encodes a region of a target page, the video of the region being reproduced, or transcodes the video concerned and transmits the transcoded video. In addition, the virtualization server captures a region, on which web data is displayed, as an image file and transmits the image file to the set top box. The set top box reproduces the video using a hardware decoding chip, and restores the target page from the image file using a low-performance CPU.
Claims16
A virtualization server, comprising:
- a parsing unit that parses a target page received from a web server to divide the target page into a moving picture area in which a moving picture is reproduced and a web data area in which web data are displayed;
- an encoder that captures the moving picture area to re-encode the moving picture when the moving picture is reproduced;
- a transcoder that downloads the moving picture and that transcodes the downloaded moving picture;
- a capture unit that captures a web data area to generate an image file;
- and
- a transmitting unit that transmits the captured image file and the re-encoded moving picture to the settop box or that transmits the captured image file and the transcoded moving picture to the settop box,
- wherein the captured image file is restored at the settop box in order to configure a web data area of the target page, the re-encoded moving picture or the transcoded moving picture is restored at the settop box in order to configure a moving picture area of the target page to constitute the target page at the settop box.
A settop box, comprising:
- an image receiving unit that receives an image file generated by capturing a web data area in which web data are displayed in a target page;
- a moving picture receiving unit that receives a moving picture re-encoded by capturing a moving picture area in which a moving picture is reproduced in the target page or that receives a moving picture generated by transcoding in the virtualization server;
- and
- a target page restoration unit that restores the web data area with the image file and that restores the moving picture area with the re-encoded moving picture or the transcoded moving picture to restore the target page.
A method of operating a virtualization server, the method comprising:
- parsing a target page received from a web server to divide the target page into a moving picture area in which a moving picture is reproduced and a web data area in which web data are displayed;
- capturing the moving picture area to re-encode the moving picture or downloading the moving picture to transcode the downloaded moving picture, when the moving picture is reproduced;
- capturing a web data area to generate an image file;
- and
- transmitting the captured image file and the re-encoded moving picture to a settop box or transmitting the captured image file and the transcoded moving picture to a settop box,
- wherein the captured image file is restored at the settop box in order to configure a web data area of the target page, and the re-encoded moving picture or the transcoded moving picture is restored at the settop box in order to configure a moving picture area of the target page to constitute the target page at the settop box.
