Hi RoHC'ers! A short question about the default-slope(TS) if value(Tsc) = 0. See RFC 4815, page 10. The default-slope is needed to compute the TS if no TS bits are received: > delta_TS = delta_SN * default-slope A packet without TS bits together with value(Tsc) = 0 is invalid: > If a packet with no TS bits is received with Tsc = 0, > the decompressor MUST discard the packet. And > If value(Tsc) = 0, the Timestamp value is compressed as-is, > and default-slope(TS) = value(TS_STRIDE). But what should I do with that default-slope(TS) = value(TS_STRIDE)? If Tsc=0 I take the TS from the packet, maybe coded as a self-describing variable length value, encode the W-LSB stuff. Is there anything I oversee where this default-slope is needed? Any help would be appreciated. br Klaus _______________________________________________ Rohc mailing list Rohc@ietf.org https://www1.ietf.org/mailman/listinfo/rohc
