nit: s/LSB/LSb/ since you are referring to the least significant bits and not
bytes?

I am referring to bits. Since the signature of this functions has changed, I
don't use LSb anymore ;)

+  void Update(uint32 data, int nbits);
+
+  bool IsValid();
+
+ private:
+  uint32 crc_;
+};
+
+}  // namespace mpeg2ts
+}  // namespace media
