摘要:
An apparatus comprising: a camera module configured to capture a first image of a subject with a first image capture parameter and at least one further image of substantially the same subject with at least one associated further image capture parameter; a reference image encoder configured to encode the first image into a first encoded image; a further image encoder configured to encode the at least one further image into at least one further encoded image; and a file compiler configured to combine the first encoding image and the at least one further encoded image into a first file.

Methods, devices, computer program products and systems for transmitting and receiving media information are disclosed. The media information is protected against errors introduce by an unreliable channel by error-protection information. The error-protection information is generated, transmitter, received and/or used in rendering based on the context of the receiver, e.g. based on a geographical location of the receiver.
摘要:
An apparatus comprising a controller configured to divide a section of an encoded multimedia signal into at least two segments depending on a time based decoding criteria; a generator configured to determine an error correction code for each of the at least two time segments; and a distributor configured to associate the error correction code for each of the at least two time segments with the section of the encoded multimedia signal and with a section of at least one further encoded multimedia signal.
摘要:
The invention relates to an encoder for forming an encoded picture stream. The pictures are defined as reference pictures or non-reference pictures, and information relating to decoding order and output order of a picture is defined for pictures of the picture stream. The encoder is arranged to form to the bitstream an indication of such a number of pictures arranged to be buffered in decoding order that is sufficient to recover the output order of pictures. The invention also relates to a signal, hypothetical encoder, decoder, hypothetical decoder, electronic device, system, software program and a storage medium.
摘要:
The invention relates to method for buffering encoded pictures. The method includes an encoding step for forming encoded pictures in an encoder. The method also includes a transmission step for transmitting said encoded pictures to a decoder as transmission units, a buffering step for buffering transmission units transmitted to the decoder in a buffer, and a decoding step for decoding the encoded pictures for forming decoded pictures. The buffer size is defined so that the total size of at least two transmission units is defined and the maximum buffer size is defined on the basis of the total size.
摘要:
A sender in a wireless network may adjust the encoding bit rate of the transmitted content and/or the transmission bit rate of the content based on the predicted future channel throughput at a predicted future geographical position of a client mobile device, such as a cellular telephone. By appropriately adjusting the bit rate prior to the client mobile device experiencing the predicted low throughput, the likelihood of continuous content consumption by the client mobile device, even while experiencing the predicted low throughput conditions, may be increased. The prediction may be performed at the network side and/or at the client mobile device side.
摘要:
A method of encoding a video signal representing a sequence of pictures, the method comprising receiving a current picture for encoding, forming a temporal prediction of the current picture from a default reference picture for the current picture, comparing the default reference picture with at least one further reference picture, calculating a measure of the similarity between the default reference picture and each further reference picture and, if the measure of similarity meets a pre-determined criterion, outputting an indicator identifying the further reference picture.
摘要:
A real-time program transmission system and method may receive a signal from a content source, and generate two different data streams. One stream may be of a higher quality than the other. The two streams may then be inserted into time slice frames, such that a single frame carries two portions of data: one corresponding to a first time segment in the program, and a second corresponding to a different time segment in the program. A receiving mobile terminal may buffer the received data, and may use the lower quality data as a backup in the event of a transmission error in the higher quality data.
摘要:
Systems and methods for using sample numbers to pair timed metadata samples with media or hint samples is provided. A timed metadata sample can be paired with media or hint samples since a sample number contained in the time media sample is provided relative to the appropriate media or hint track. Additionally, an offset of sample numbers, applicable to scenarios where a plurality of timed metadata samples exist, may be added to the provided sample number to obtain the actual sample number within the media or hint track.
摘要:
A system, method and computer program tangibly embodied in a memory medium for implementing motion skip and single-loop decoding for multi-view video coding. In various embodiments, a more efficient motion skip is used for the current JMVM arrangement by 8×8 or 4×4 pel disparity motion vector accuracy, while maintaining the motion compensation process that is compliant with the H.264/AVC design regarding hierarchical macroblock partitioning. Adaptive referencing merging may be used in order achieve a more accurate motion skip from one inter-view reference picture. In order to indicate whether a picture is to be used for motion skip, a new syntax element or syntax modification in the NAL unit header may be used.
