Fim da televisão terrestre analógica...

Fica o registo da última transmissão de televisão analógica no território Português: os paineis informativos sobre o apagão...

Imagem 1: Espectro UHF - o sinal TDT em 754MHz é perfeitamente visível, mas continuam 3 emissores analógicos! Estes destingem-se pelo facto do pico vídeo ser acompanhado com um pico menor à direita, onde é transmitido o sinal áudio.

Imagem 2: Ao seleccionar a frequência de 495MHz aparece de facto uma emissão analógica...

Imagem 3: ...que apresenta apenas o painel informativo sobre o apagão analógico!

Imagem 4: Medição da frequência do transponder TDT - 754 MHz

Imagem 5: O sinal TDT é recebido com uma intensidade de 64dBuV, o que é mais do que suficiente, já que na transmissão digital, os factores importantes são MER (Modulation Error Rate) e BER (Bit Error Rate).

Abschied vom Analogen Sat-Empfang

Ich habe ein Video vom letzen Tag des analogen Satelliten-Empfangs auf Astra 19.2E auf Youtube veröffentlicht. Bitte lest die Beschreibung.

I have uploaded a video on Youtube, which documents the last day of analogue satellite transmission on Astra 19.2E.

The video shows the remaining channels, which show a scrolling text alerting to the immediate switch off. The noise in some passages is on purpose, to show the effects of bad receptions on analogue broadcasts.

Unfortunately, my capture device shuts of image on white noise...

The video was rendered with an Emitor Satlook Digital Color, the spectrum shows the analogue transponders. These have not just been replaced/switched off - they continue(d) to broadcast an info-page and are gradually replaced by new DVB-S2 transmissions.
