Abstract An $(a,b,\tau)$ streaming code is a packet-level erasure code that can recover under a strict delay constraint of $\tau$ time units, from either a burst of $b$ erasures or else of $a$ random erasures, occurring within a sliding window of time duration $w$. While rate-optimal constructions of such streaming codes are available for all parameters $\{a,b,\tau,w\}$ in the literature, they require in most instances, a quadratic, $O(\tau^2)$ field size. In this work, we make further progress towards field size reduction and present rate-optimal $O(\tau)$ field size streaming codes for two regimes: (i) $gcd(b,\tau+1-a)\ge a$ (ii) $\tau+1 \ge a+b$ and $b \mod \ a \in \{0,a-1\}$.
