TH84592A - H.264 scalable video coding of interest areas - Google Patents

Abstract

Encoder invention, decoders, consistent encoding and decoding methods, video signal structures and storage medium will be provided for scalable video encoding and decoding. The scalable video encoder has an encoder portion (100) for encoding the image to generate the base layer bit stream and the bit stream in the enhanced layer. The bit stream in the base layer and the bit stream in the enhancement layer are generated by dividing the image into multiple image blocks, grouping multiple image blocks into one or more slices in the bit stream in the base layer. And into two or more slices in the bit stream in the enhanced layer, encoding all of the slices of one or more in the bit stream in the base layer and less than the total slices of the two. A group or more in an improvement floor Where at least one of the slices from two or more slices is not intentionally encoded in the bit stream in the modifier layer, encoding syntactic elements in the header to indicate the slice group that Not being intentionally encrypted in one or more update layers.

Claims (6)

Disclaimer (ALL) that will not appear on the advertisement page: Disclaimer 1. Scalable video encoding device that includes: Encoder for encoding images to create base layers and enhancement layers by dividing images into multiple image blocks and linking multiple image blocks to one or more slices; encoding all slices, one or More than that for all base layers and slices, less than one or more for enhancement layers; And encoding syntactic elements to indicate at least one unencrypted slice in the enhancement layer. 2. The equipment of claim 1, with the modifier floor, will be built to support at least one specific area program. Where all slides are less than one or more for the modifier layer, which is encoded, fever in the modifier layer is included in the slice group, which contains the area of interest while the slide. At least one unencrypted layer in an enhancement layer is included in at least one slice group that has no area of interest. 3. The device of claim 1, where the syntactic element is included in the header. 4. Scalable video encoding methods include: Image encoding for base and enhancement layers Where the aforementioned encryption procedure is included Splitting an image into multiple image blocks; Linking multiple image blocks to one or more slides; Encoding all slices one or more for the base layer and all slices less than one or more for the enhancement layer; And encoding syntactic elements to indicate at least one unencrypted slice in an enhanced layer. 5. Method of claim 4, whereby the improvement floor will be created to support at least one area of interest program. All sliced streams less than one or more for the modifier layer, which is encoded, the fever in the enhanced layer is included in the slice group that contains the area of interest. While at least a few unencrypted slides in the enhancement layer are included in the slide group, at least one of the pointer groups has no area of interest. 6. Method of claim 4, where syntax elements are included in the header. 7. Scalable video decoding equipment, which includes a decoder for decoding of the base layer and the enhancement layer by parsing the syntactic elements that indicate that one or more slides are not. Was intentionally encrypted in an enhancement layer; decoding of one or more slices that were not intentionally encoded in the update layer using only the base layer information; And decoding of any remaining slices from multiple slices in the enhancement layer using the information of the enhancement layer 8. Device of Clause 7, where syntactic elements are included in the header 9. Device of clause Holds 7, where the decoder uses INTRA BL mode to decode one or more of the slides that are not encoded in the enhancement layer, regardless of whether multiple loop decoding is given. Is it recommended to use the specific nitration indicated for the adjustment class? 1 0. Equipment of the claim. 7 where the decoder uses BL_SKIP mode to decrypt one or more slices that are not encrypted in Enhancement Layer 1. 1. Device of claim 7 where the decoder is said to follow the error concealment method to slash one or more unencrypted clients in the enhancement layer when sliced. Any or more that are not encrypted in the update layer are detected as missing. But not specified in the sequence parameter set and the image parameter set corresponding to the improvement class 1. 2. Methods for decoding scalable videos include: Syntactic component parsing indicating that one or more slices are not intentionally encoded in an enhanced layer; decoding of one or more slices that are not intentionally encrypted in The update layer uses only the information of the base class; And decoding any remaining slices from multiple slices in an enhancement layer using the information of enhancement layer 1. 3. Method of claim 12, where the syntactic element is included in header 1. 4. The method of claim 12, where INTRA_BL mode is used to decode one or more of the slides that are not encoded in the modulation layer, regardless of multi-loop decoding.

Claim Method 12 where BL SKIP mode is used to decrypt one or more slices that are not encrypted in the modulation layer 1. 6. The 12 Claims Method also includes the implementation of the Error Concealment Method to hide one or more unencrypted slices in the adjustment layer when sliced. One or more, which is not encrypted in the update layer, was detected as missing. But not specified in the sequence parameter. And a set of image parameters corresponding to the adjustment layer
