Hej, er der mulighed for og få en oversigt over bitraten på Yousee DVB-C, jeg kan finde en oversigt på Yousee forum fra 2021, men er interesseret i en der er nyere

Eventuelt om nogen kan måle bestemte kanaler, fortælle hvordan man måler eller har en oversigt jeg ikke kan finde?

Nu, her omkring 21 tiden d.d:

Det ses at status på de testede kanaler herunder generelt er generelt ~12 Mb/s overall variabel bitrate med 10-11 af dem til video encodes som H.264/AVC + lyd der meget varierende ses fra enten fra 128 til 384 kb/s MP2 (stereo) eller 128 kb/s (stereo) eller 384 til 448 kb/s AC3/Dolby Digital (5.1).

Kanalerne er enten 1080i eller 720p og enten 25 eller 50 fps i overenstemmelse med hvordan det aktuelt producerede program er produceret og udsendt fra kanalen.

Lyden er såden mere 'all over the place'. Det er muligt det er forskelligt fra kanal til kanal, eller fra udsendelse til udsendelse (som f.eks. fps) ihht hvad kanalen udsender, men det har jeg ikke overblik over.

Fedt, lige det jeg manglede. Hvordan er du kommet frem til dette, altså hvordan har du målt det? Der er nemlig flere kanaler jeg gerne vil se og håber på en måde selv og kunne måle på

Jeg har bare optaget bitstreamen via DVB-C tuner tilsluttet PC og aflæst mediainfoen fra filen (deraf Filenavn, Size og Duration i status). Man vil også kunne køre en egentlig bitrateanalyser af filen hvis man skulle ønske sig det. Af den kan jeg se at TV-avis klippet f.eks. har haft en max bitrate på 12,992 og en minimum bitrate på 8.460
