Embodiment Construction

[0017] In the following description, functions and constructions that are well known to those skilled in the art are not described in detail because unnecessary detailed description would obscure the present invention.

[0018] The invention relates to a video communication system for processing digital video signals.

[0019] exist figure 1 Such a system as described in can be used for video applications in MPEG2 or MPEG4, wherein the video communication system comprises a transmitter TRANS, a transmission medium CH and a receiver RECEIV. Said transmitter TRANS and said receiver RECEIV comprise an encoder ENC and a decoder DEC respectively.

[0020] In order to efficiently transmit some video signals through the transmission medium CH, wherein the transmission bits of the video signals are known as the bit stream BIT_STR, the encoder ENC encodes the video signals, and then sends the encoded video signals to the decoder DEC, which The signal is decoded. Finally, the receive...

Abstract

The present invention relates to a video communication system (SYS), which is able to receive a digital video signal, said digital video signal comprising some sets of objects (OBJ) with components (COMP). The invention is characterized in that it comprises:- availability information (FLAG) for determining if a component (COMP) of said object (OBJ) is to be encoded and transmitted via the transmission channel (CH), - encoding means for encoding a component (COMP) of said object (OBJ) if the availability information (FLAG) is enabled,- decoding means for decoding said component (COMP) of said object (OBJ) if the availability information (FLAG) is enabled, and,- retrieving means for retrieving said component (COMP) of said object (OBJ) if the availability information (FLAG) is disabled.

Description

technical field [0001] The invention relates to a video communication system according to the preamble of claim 1, capable of receiving digital video signals. The invention further relates to a method of processing a digital video signal according to the preamble of claim 8 . [0002] Such systems can be used, for example, for 3D video applications in the MPEG standard. Background technique [0003] A video communication system typically includes a transmitter with an encoder and a receiver with a decoder. This system receives an input digital video signal, encodes said signal through an encoder, sends the encoded signal to a receiver, and then decodes the sent signal through a decoder to obtain an output digital video signal, which is the input digital Reconstruction signal of video signal. The receiver then displays the output digital video signal. A digital video signal includes groups of objects characterized by certain components such as shape, texture, motion infor...
