Abstract: A first shaped video signal V₁K₁ and a second shaped video signal V₂V₂, are combined so as to generate a third shaped video signal V₃ʹ given by 
    V₃ʹ = V₁ K₁ [l - K₂(l - P₁₂)] + V₂K₂(l - K₁P₁₂) 
where P₁₂ is a priority signal. a key signal K₃ given by 
    K₃ = l - (l - K₁)(l - K₂) 
is also generated. An output processor receives the shaped video signal V₃ʹ, the key signal K₃ and a matte signal M₃. In a first mode of operation, the output video signal V₃ʺ of the output processor is given by 
    V₃ʹʹ = V₃ + M₃(l - K₃) 
and the key signal K₃ʹ that is generated by the output processor has a constant value, and in a second made of operation of the output processor the output video signal is given by 
    V₃ʹʹ = V₃ʹ/K₃ 
and the key signal K₃ʹ is directly proportional to K₃.

Abstract: Actin and myosin is extracted from pre-rigor muscle using a brine solution containing salt at between 3% and 18% by weight, and optionally food phosphates at 0.05% to 2 wt. %. Comminuted or chopped pre-rigor meat is mixed with the brine in a ratio between 2:1 and 4:1 to yield a slurry or paste-like mixture. The temperature is maintained below 30°C to prevent the proteins denaturing. The slurry is stored in the absence of oxygen at 0°C or dried e.g. by drum drying to a particulate material which can be kept at room temperature under anoxic conditions. On heating above 50°C the protein product gels and by its presence in a meat product during cooking it provides good water holding properties and good binding properties. When used in processed meat products it can improve both succulence and organoleptic properties.
