Er der nogen der har en sammenligning mellem
Yousse->kabel->boks
og
Yousee Play->App på tv/appletv?
Kvaliteten via DVB-c (som jeg tænker du mener når du siger (Yousee->kabel->boks) og så YouSee play er signifikant. Jeg har ikke selv kunnet tjekke bitraten på YouSee play, men kan fra netsøgning se at man nok skal regne med noget omkring 5 mbps som udgangspunktet, især hvis det er samme encode som på YouSee film og TV appen. Hvis du bruger YouSee's boks til streaming og det ikke handler om DVB-c vs streaming, så kan det meget vel være samme encode der benyttes og i så fald vil du ikke opleve nogen forskel, da det er så ikke er et spørgsmål om streaming vs DVB-c
Der er omkring små 12 Mbps via DVB-c, jeg har nedenfor lige copy og pasted de sidste målinger jeg lavede tilbage i 2023 til syn på sagen - Bemærk dog at der gøres brug af både forskellige codecs og at nogle kanaler udsendes interlaced, men den markant højere bitrate sikrer dog stadig signifikant bedre HD kvalitet via DVB-c.
