摘要： The invention relates to a method for obtaining media data and metadata from an encapsulated bit-stream resulting from the encapsulation of one or more bit-streams, the media data of each of the one or more bit-streams being organized into one or more layers, each layer comprising timed samples or sub-samples. A data structure is obtained for referencing metadata including at least one definition of at least one group of timed samples of the media data. At least one operating point descriptor is obtained for each of the one or more bit-streams, the at least one operating point descriptor providing metadata related to descriptive information enabling timed samples belonging to a group of timed samples defined in metadata referenced by the data structure to be independently decoded. Each operating point descriptor associated with one group of timed samples defines the descriptive information of the timed samples belonging to the group.

摘要： A method of encapsulating an encoded bitstream representing one or more images includes providing description of images and/or sub-image picture, providing composed picture description, and outputting the bitstream. The description of images and/or sub-image pictures identifying portions of the bitstream representing the images and/or sub-images of the one or more images is provided. The composed picture description of at least one composed picture formed by one or more images and/or sub-image pictures also is provided. The bitstream, together with the composed picture description, is output as an encapsulated data file.

摘要： Recording apparatus (100) is described that provides for content authentication. The apparatus (100) has a first storage media (109) for storing at least a digital certificate (115) and a pair of cryptographic keys comprising a private key (113), and a public key (114) corresponding to the private key. A recording arrangement (150, 101-105) operates to record event data (112) and a second storage media (108) is configured for storing at least the recorded event data. A signing processor (107) generates a digital signature (118) using at least the stored private key (113) and the recorded event data (112). A controller (160) is arranged to cause the apparatus to supply the stored public key (114) to a certificate generating authority (560), store (119) the digital certificate (115) in at least the second storage media (108), the certificate being formed using the public key (114) and supplied to the apparatus from the certificate generating authority (560), and to record the event data (112) and to associate a digital signature (118) generated by the signing processor (107) with the event data (112), thus forming an authenticable communications package (120). Also disclosed is method of authenticating recorded data received by way of the communication package (120). The method includes verifying (417) the certificate (119) using a public key (415) of the certifying authority (560), and verifying (411) the digital signature (118) and the public key (114, 413) of the apparatus (100). If both the certificate (119) and the signature (118) positively verify, the recorded event data (112) is said to be authentic.

摘要： A method ( 200 ) of enhanced peak detection in a correlation signal (g(x)) is disclosed. The method ( 200 ) comprises identifying ( 215 ) in the correlation signal (g(x)) positions where the modulus value of the correlation signal is above a first predetermined value. Each of the identified positions is then processed by forming ( 220 ) a sub-signal from the correlation signal by isolating a region of samples, the region comprising substantially equal numbers of samples on opposite sides of the identified position. The sub-signal is then up-sampled ( 221, 222, 225 ) to a higher resolution using Fourier interpolation. The up-sampled sub-signal is searched ( 230 ) for a peak value, and when the peak value is greater than a second predetermined value, parameters associated with the peak value is stored ( 236 ).

摘要： A method inverse discrete wavelet transforms subband data in segments and maintains a state between segments. The method selects one of a plurality of different computational procedures for performing the inverse DWT by testing the state and the subset of the current segment of subband data to determine if a current segment can be inverse transformed with a reduced computation procedure. If the test is positive the method performs the inverse DWT using the reduced computation procedure; otherwise the method performs the inverse DWT of the segment using another procedure.
