measurement for the power consumption of audio, video and related equipment)

Project: IEC 62455 Ed.1: IP and transport stream based service access (TC 100 TA1)- DLNA scope is limited to a homenetwork, while the scope of 100/1141A/CDV is terminal for broadcast systems. These fields are different. DLNA uses HTTP as the common content transfer protocol, and HTTP is not suited for broadcast applications. Furthermore, so far DLNA has only selected link protection technologies such as DTCP-IP for the narrowest possible scope, streaming from a media server that is in the proximity of the media renderer. These technologies are not suitable for broadcast applications, and they will not work in any applications in which the server is outside the home network; - Section 4.1.1 of 100/1141A/CDV describes the selected technologies, and the goal has been to maximize the use of existing protocols wherever applicable

Loi de ZIPF sur n programmes ou chaînes classées par ordre d'audiences décroissantes, la Mième a M fois moins d'audience que la "pseudo première", pseudo car en fait les 4 ou 5 premières chaînes doivent traitées séparément Permet un calcul sommaire par les approximations

Sigma (i de 1 à n) i = 0,577+ ln (n) Sigma (i de 1 à n) ia = Zeta[a]-Zeta[a, n+1]

Audience de la Mième = (Audience totale des n chaînes)/ (0,577+ ln (n) )/M

La 30ème chaîne parmi 100 a 6 pour mille de l'audience

La 100ème chaîne parmi 100 a 2 pour mille de l'audience

Les quatre premières ensemble 40% de l'audience pour 100 chaînes mais 28% de l'audience pour mille chaînes

Lorsque le réseau est segmenté par groupe de 1000 logements ou 1000 téléviseurs en service, les programmes 101 à 1000 sont ils à mettre en "diffusé" ou en "à la demande"?
