Abstract
In a picture signal processing method, an analog picture signal (APS1, APS2) is processed (PSP) in dependence on a quality indication (QI1, Q12) relating to the analog picture signal (APS1, APS2) and received together with the analog picture signal (APS1, APS2). Preferably, the analog picture signal (APS1, APS2) has been obtained from a digital picture signal that has been encoded at a bit-rate and/or at a compression ratio and/or at a quantization level, wherein the quality indication (QI1, QI2) is the bit-rate and/or the compression ratio and/or the quantization level.
Claims13
A picture signal processing method comprising the steps:
- receiving an analog picture signal and a quality indication relating to the analog picture signal;
- and
- processing the analog picture signal in dependence on the quality indication,
- wherein the analog picture signal is formed by decoding a digital picture signal having been encoded at a bit-rate and/or at a compression ratio and/or at a quantization level, and wherein the quality indication is the bit-rate and/or the compression ratio and/or the quantization level and/or other information about the encoding or decoding.
A picture signal processing device, comprising:
- means for receiving an analog picture signal and a quality indication relating to the analog picture signal;
- and
- means for processing the analog picture signal in dependence on the quality indication,
- wherein the analog picture signal is formed by decoding a digital picture signal having been encoded at a bit-rate and/or at a compression ratio and/or at a quantization level, and wherein the quality indication is the bit-rate and/or the compression ratio and/or the quantization level and/or other information about the encoding or decoding.
A picture signal supplying method comprising the steps of:
- receiving a digital picture signal having been encoded at a bit-rate and/or at a compression ratio and/or at a quantization level;
- decoding the digital picture signal to form an analog picture signal;
- generating a quality indication related to the analog picture signal, said quality indication being the bit-rate and/or the compression ratio and/or the quantization level and/or other information about the encoding or decoding;
- supplying the analog picture signal;
- and
- supplying the quality indication.
A picture signal supplying device, comprising:
- an input to which a digital picture signal is applied, said digital picture signal having been encoded at a bit-rate and/or at a compression ratio and/or at a quantization level;
- means for decoding the digital picture signal to form an analog picture signal;
- means for generating a quality indication related to the analog picture signal, said quality indication being the bit-rate and/or the compression ratio and/or the quantization level and/or other information about the encoding or decoding;
- means for supplying the analog picture signal;
- and
- means for supplying the quality indication.
