Embodiment Construction

[0026] figure 1 is a block diagram illustrating the general path taken by video data distributed over a network. An input video signal 10 is fed to an encoder 12 which converts the signal 10 into machine readable video data in the form of a series of bits or a stream of bits. Then, the video data is stored in the server 14, waiting for a request for the video data. When server 14 receives a request for video data, it sends the data to transmitter 16, which sends the data along communication channel 18 on the network. Receiver 20 receives the data and sends it to decoder 22 in the form of a bit stream. Decoder 22 converts the received bitstream into a ready-to-view output video signal 24 .

[0027] The encoding performed by encoder 12 may involve lossy compression techniques, such as MPEG-4, resulting in a base layer, ie a data volume sufficient to allow the generation of a visual video sequence of lower quality than that represented by the source video sequence. The base l...

Abstract

During encoding, video data is represented as a bitstream of a quantized base layer and at least two enhancement layers, where each picture in each layer is identified by a start code. The base layer plus a certain number of enhancement layers that can be transmitted according to the bandwidth of the communication channel are transmitted on the communication channel.

Description

[0001] This is a non-provisional application claiming the benefit of the provisional application entitled "Proyiding Prediction Mode Fine Granularity Scalability" filed on January 9, 2001. technical field [0002] The present invention relates to video systems and methods with fine-grained scalability. Background technique [0003] A video signal is primarily a series of still pictures that follow one another in rapid succession, giving the viewer the illusion of motion. Analog video signals may need to be converted, or "encoded," into digital form before they can be transmitted over a communication channel. In digital form, video data consists of a series of bits called a "bitstream". When the bitstream arrives at the receiving location, the video data is "decoded," that is, reconverted into a viewable form. Due to the bandwidth limitations of the communication channel, video data is often "compressed" prior to transmission over the communication channel. Compression may...
