  We apply the coded caching scheme proposed by Maddah-Ali and Niesen to a
multipoint multicasting video paradigm. Partially caching the video files on
the wireless devices provides an opportunity to decrease data traffic load in
peak hours via sending multicast coded messages to users. In this paper, we
propose a two-hop wireless network for video multicasting, where the common
coded multicast message is transmitted through different single antenna Edge
Nodes (ENs) to multiple antenna users. Each user can decide to decode any EN by
using a zero forcing receiver. Motivated by Scalable Video Coding (SVC), we
consider successive refinement source coding in order to provide a ``softer''
tradeoff between the number of decoded ENs and the source distortion at each
user receiver. The resulting coding scheme can be seen as the concatenation of
Maddah-Ali and Niesen coded caching for each source-coded layer, and multiple
description coding. Using stochastic geometry, we investigate the tradeoff
between delivery time and per-user average source distortion. The proposed
system is spatially scalable in the sense that, for given users' and ENs'
spatial density, the achieved distortion-delivery time performance is
independent of the coverage area (for in the limit of large area).
